Proven AI Search Optimization Guide 2026: Boost Rankings in Google AI & ChatGPT

Search stopped being ten blue links a while ago. Today, the majority of informational queries on Google trigger an AI Overview before a single traditional result appears, and a growing share of research journeys now start inside ChatGPT or Perplexity instead of a search box at all. If your content strategy still treats “ranking ” as the finish line, you’re optimizing for a search experience that fewer and fewer people actually see.

AI Search Optimization (ASO) is the discipline of structuring, writing, and technically preparing content so that AI systems — Google AI Overviews, AI Mode, ChatGPT, Perplexity, and Gemini — can retrieve it, trust it, and cite it inside a generated answer. It sits alongside traditional SEO rather than replacing it, but it has its own rules, its own failure modes, and its own metrics.

This guide walks through exactly how each major AI system selects sources, what separates content that gets cited from content that gets ignored, and a practical, step-by-step framework you can apply this week. At Pentox Studio, this is the same process we run inside our own SEO Services and Technical SEO Services engagements, so everything here reflects what actually moves the needle in live AI Overview and ChatGPT citation tracking — not recycled theory.

What Is AI Search Optimization (ASO)?

AI Search Optimization is the process of making a website’s content extractable, verifiable, and citable by generative AI systems that answer questions directly instead of just linking to pages. Where traditional SEO optimizes for a ranking position in a list, ASO optimizes for a specific outcome: being the passage an AI model lifts, paraphrases, or names when it builds its answer.

You’ll also see this discipline called:

GEO (Generative Engine Optimization) — the term most commonly used in academic and enterprise research
AEO (Answer Engine Optimization) — focused specifically on direct-answer formats
LLM SEO — optimizing for how large language models retrieve and represent information

These terms overlap heavily and, in practice, most agencies (Pentox Studio included) use them interchangeably. What matters is the underlying mechanic: every AI search system — regardless of vendor — runs some version of retrieve, evaluate, extract, synthesize, cite. Your content has to survive all five stages, not just rank well in the first one.

Why ASO Exists as a Separate Discipline

Three structural shifts made ASO necessary:

Retrieval and citation are now separate steps. A page can be retrieved by an AI system and still never be cited. Research on ChatGPT’s browsing behavior found that ChatGPT cites only around 15% of the pages it retrieves, with the other 85% read by the model but never referenced in the output. Ranking well enough to be retrieved is necessary but no longer sufficient.
AI systems evaluate passages, not pages. Google’s AI breaks pages into smaller sections and evaluates individual passages, meaning even a single well-written section can be selected even if the rest of the page is mediocre.
Zero-click behavior is now the default for informational queries. When an AI Overview fully answers a question, the user often never clicks through — which means your visibility now depends on being named inside the answer, not just appearing below it.

AI Search vs Traditional SEO

The two disciplines share a foundation — technical crawlability, authority, and topical relevance still matter enormously — but they diverge in what “winning” looks like and how content earns it.

Dimension	Traditional SEO	AI Search Optimization
Goal	Rank in position 1–10	Be the source an AI cites or paraphrases
Unit of evaluation	Whole page	Individual passage or section
Success metric	Click-through rate, rankings	Citation frequency, share of AI answer
Content structure	Keyword-optimized headings	Answer-first, self-contained passages
Freshness window	Weeks to months	Often 48 hours to 30 days for volatile topics
Authority signal	Backlinks, domain rating	Backlinks + third-party mentions + entity clarity
Traffic pattern	Multiple clicks per session	Fewer, but far more qualified clicks

That last row matters more than most teams realize. Analysis of post-AI-Overview click behavior found that users who click through from an AI Overview arrive already convinced of a site’s credibility because the AI has effectively endorsed the content, with some datasets suggesting these visitors convert at dramatically higher rates than traditional organic visitors. Fewer clicks, but the ones you get are warmer leads — which is exactly why ASO belongs in the same conversation as Digital Marketing Services and lead generation, not just visibility metrics.

How Google AI Overviews Choose Sources

Google hasn’t published a formal ranking algorithm for AI Overviews, but citation-pattern analysis across thousands of queries reveals a consistent process.

The Selection Mechanism

Google’s system starts from the traditional organic index, then layers AI evaluation on top. As one analysis of the process describes it, Google’s systems scan indexed content, evaluate source credibility, assess answer completeness, and synthesize the most helpful response in a dynamic, real-time process for each query. This means:

You generally need to already be indexable and reasonably relevant to be considered at all
The AI then re-evaluates candidate pages at the passage level, not the page level
Multiple sources are frequently blended into a single answer, so you’re not just competing for one slot — you’re competing to be one of several contributors

E-E-A-T Has Become a Functional Filter, Not Just a Guideline

This is the single biggest shift of 2026. What used to live only in Google’s quality rater guidelines now functions as an active filter: Experience, Expertise, Authoritativeness, and Trustworthiness have shifted from quality rater guidelines to functional ranking filters, and content without clear E-E-A-T signals increasingly fails to appear in AI Overviews regardless of other optimization efforts. Specifically, Experience has become particularly critical, with Google’s algorithms actively identifying content created by people with demonstrated first-hand knowledge — directly targeting the flood of generic, first-person-free AI-generated content across the web.

Freshness and Historical Trust Compound Each Other

Two separate signals reinforce one another. Recency is a strong tie-breaker — an article with a current-year timestamp will almost always be selected over an older one for a “best of” list. But recency alone doesn’t build a durable advantage. A website’s historical reputation still plays a role in source selection, and once Google’s AI determines a site is a reliable source for a topic, it tends to keep returning to that site, making new content from that domain easier to get selected quickly. In practice, this means a domain that consistently publishes accurate, well-structured content on a topic builds a compounding advantage that a single well-optimized page cannot replicate alone — which is why topical depth (multiple related articles) consistently outperforms a single “pillar page” trying to cover everything.

Information Gain Is a Real, Measurable Filter

Google increasingly penalizes redundancy. If a page simply repeats information that already exists elsewhere, it is less valuable to Google’s AI; pages that contribute meaningful new insights, explanations, or perspectives are preferred. This is the death knell for content that summarizes competitors without adding anything new — a pattern distressingly common in AI-generated “10 best tools” listicles.

Preferred Sources: A New (and Growing) Signal

In May 2026, Google extended its Preferred Sources feature — previously limited to the Top Stories carousel — directly into AI Overviews and AI Mode. Choosing a site as a preferred source in Top Stories now also shapes that reader’s AI Mode and AI Overviews results, and vice versa. The scale is already meaningful: by the rollout, users had selected more than 345,000 unique sources, and Google itself reports that people are twice as likely to click through to a source they’ve marked as preferred.

Importantly, this is currently a visibility and click-through mechanism, not a direct ranking factor — it highlights selected sources in certain Google surfaces and can increase their click-through there, but a site’s organic position in classic search is not directly changed by it. That said, Google has stated it is working on using Preferred Sources as a ranking signal across its AI features going forward, so building an active opt-in campaign now — asking loyal readers to mark you as a preferred source — is a low-cost, high-upside move worth adding to any Local SEO Services or content marketing plan today.

How ChatGPT Selects and Cites Information

ChatGPT’s citation behavior is fundamentally different from Google’s because it isn’t operating its own web index — and understanding that distinction changes everything about how you optimize for it.

Two Very Different Modes, One Common Confusion

AI Search Optimization (ASO): The Complete 2026 Guide to Ranking in Google AI Overviews, ChatGPT & Perplexity

Search stopped being ten blue links a while ago. Today, the majority of informational queries on Google trigger an AI Overview before a single traditional result appears, and a growing share of research journeys now start inside ChatGPT or Perplexity instead of a search box at all. If your content strategy still treats “ranking #1” as the finish line, you’re optimizing for a search experience that fewer and fewer people actually see.

How ChatGPT Selects and Cites Information

Two Very Different Modes, One Common Confusion

ChatGPT operates in two source mechanisms: parametric memory, where it generates answers from training data with no live retrieval and a real risk of outdated or fabricated information, and browsing mode, which is Bing-powered and produces real, verifiable citations. Most users don’t consciously track which mode is active for a given answer — which means your optimization strategy has to assume browsing mode will eventually be triggered for any commercially relevant query, even if a specific session happens to answer from memory.

What Determines Citation in Browsing Mode

When browsing mode activates, ChatGPT weighs a combination of authority and content quality. Independent analysis puts the weighting at roughly domain authority around 40%, content quality around 35%, and platform trust around 25%, typically surfacing three to six clickable citations per response. This is a meaningfully steeper authority curve than classic Google SEO: research from SE Ranking found sites with over 32,000 referring domains are 3.5 times more likely to be cited by ChatGPT than sites with fewer than 200 referring domains, describing this as an authority “trust cliff” — ChatGPT is risk-averse and prefers sources it can confidently attribute.

Structure Beats Cleverness

ChatGPT strongly favors a specific content pattern researchers call BLUE (Bottom Line Up Front) formatting: when a user asks an informational query, ChatGPT triggers BLUE formatting, so content with clear definitions at the top is more likely to be cited. This lines up with a separate structural finding that 44% of citations come from the first third of a webpage’s content — meaning burying your best answer under 600 words of preamble is one of the most common (and easily fixed) reasons content never gets cited.

Freshness Beats Authority in Time-Sensitive Categories

Domain authority isn’t everything. For fast-moving topics, an outdated page from a strong domain will still lose to a fresher page from a weaker one: if a competitor has a “Best CRM 2026” guide updated this week while your equivalent guide is from last year, ChatGPT will more likely cite and link the competitor, even if your site has higher traditional SEO authority.

Win the First Question, Not the Follow-Up

One of the more counterintuitive findings from large-scale conversation analysis: citation opportunity is concentrated almost entirely in the opening question of a research session. Turn 1 is 2.5 times more likely to trigger a citation-generating web search than turn 10, and nearly 4 times more likely than turn 20 — so the practical implication is to target the first question someone asks when starting a research journey (“what is X,” “best X for Y,” “how does X work”), not the narrower clarifying questions that follow. And when it comes to general knowledge queries, don’t underestimate the incumbent: Wikipedia

serves as the default knowledge layer, appearing in roughly one in six cited conversations.

How Perplexity Ranks and References Websites

Perplexity is built around live retrieval for nearly every query, which makes it the most immediately responsive of the three platforms — and, in some ways, the most meritocratic.

A Smaller, More Curated Pool

Unlike Google’s massive index, Perplexity draws from a smaller pool of trusted sources, which means authority signals and citation patterns matter more than raw backlink volume. Perplexity’s own ranking pipeline runs in stages: retrieval-augmented generation first pulls candidate pages based on query matching and authority signals, then a separate ranking model scores those pages on quality, trust, and structural clarity to determine which ones actually appear as citations.

Freshness Windows Can Be Brutally Short

Perplexity rewards genuinely current content more aggressively than any other platform. Content published or updated within the last 30 days receives a measurable citation boost, and for rapidly developing topics that window can compress to just 48 to 72 hours. If you’re publishing in a fast-moving category — AI tools, algorithm updates, product launches — a content calendar built around monthly refreshes is already too slow.

Topical Authority Can Beat Domain Size

This is the finding that surprises most SEO practitioners: Perplexity doesn’t simply defer to the biggest domain. In one documented case, a niche blog focused specifically on agency operations was cited over much larger general publishers for a specific comparison query, directly contradicting the traditional SEO assumption that domain authority predicts ranking. This pattern holds at scale — one analysis found 92.78% of Perplexity’s cited pages had fewer than 10 referring domains. The takeaway for smaller or newer sites: deep, narrow expertise on a specific subtopic can out-cite a broad authority site that only covers the topic superficially. This is precisely the logic behind building out topic clusters through consistent Content Marketing rather than chasing a single “ultimate guide.”

Extractability Is Non-Negotiable

Being trustworthy isn’t enough if your claims can’t be safely lifted out of context. Perplexity cannot safely extract a claim when the meaning shifts between the source and the quote — which is why a page with strong Google rankings can still be invisible to Perplexity if its claims are buried, ambiguous, or structurally difficult to attribute. And accuracy at scale is harder than it looks: even frontier models achieve only 39–77% factual accuracy when citing sources at scale — a strong argument for writing single, self-contained, unambiguous sentences that state a fact plainly rather than burying it in a compound clause.

Exact-Match Phrasing Matters More Here Than on Any Other Platform

Perplexity diverges from ChatGPT in one specific way: it rewards literal phrase matching more heavily. ChatGPT tolerates partial or semantic matches, but Perplexity prefers pages whose titles, headings, or metadata mirror the exact wording of the query. Practically, this means mining Perplexity’s own autosuggest and “related questions” for exact phrasing — and mirroring that phrasing in your H2s and H3s — is a higher-leverage tactic here than it is for ChatGPT or Google AI Overviews.

Understanding LLM SEO and Generative Engine Optimization (GEO)

GEO is best understood as the connective layer across all AI platforms — the set of practices that improve your odds regardless of which model is doing the retrieving. Across ChatGPT, Perplexity, and Google AI Overviews, researchers converge on the same short list of universal factors: crawlability, content freshness, entity clarity, topical authority, structured information, and source trust.

A few GEO-specific practices worth calling out explicitly:

Entity clarity over keyword density. Perplexity evaluates topical relationships, not just isolated keywords — meaning your content needs to clearly establish what it’s about (a specific product, method, or concept) and how it relates to adjacent entities, not just repeat a target phrase.
Structured data as a trust accelerant. While schema alone won’t guarantee citations, clear markup makes content easier for retrieval systems and language models to interpret, classify, and trust during answer generation.
External validation compounds internal optimization. AI systems use external references as trust and authority signals, so digital PR, reviews, expert mentions, podcasts, and industry citations directly support AI search visibility — this is where Social Media Marketing and PR-driven link earning intersect directly with ASO, rather than sitting in a separate silo.
Earned media outranks brand-owned content for ChatGPT specifically. Across six independently studied predictors of ChatGPT citation share, earned media presence in trusted third-party publications emerged as the single largest factor, with ChatGPT preferentially citing third-party authoritative coverage over brand-owned pages. In practice: a guest feature or expert quote in an industry publication can outperform ten posts on your own blog.

EEAT and AI Search Visibility

EEAT (Experience, Expertise, Authoritativeness, Trustworthiness) isn’t new, but its role has changed from “helps you rank slightly better” to “gates whether you appear at all” in AI-generated answers.

Experience Is the New Tie-Breaker

As covered above, Google’s systems in 2026 actively hunt for markers of genuine first-hand experience — the kind of specific, situational detail that a purely synthetic article can’t fake convincingly. Practical signals include:

Specific numbers, timeframes, and outcomes from real projects (not generic ranges)
Named case studies with verifiable client or project context
First-person observations (“we tested this across 40 client accounts” beats “many experts recommend”)
Original images, screenshots, or data visualizations rather than stock graphics

Build a Visible Author and Organizational Entity

AI systems cross-reference author and brand identity against external mentions to validate trustworthiness. This means:

Every article should carry a named author with a real bio, credentials, and links to their other published work
Your organization needs a consistent entity presence — the same name, description, and details — across your website, Google Business Profile, LinkedIn, and industry directories
Author and organization schema markup (covered next) should reinforce, not just repeat, this information

Trustworthiness Is Increasingly External, Not Just On-Page

You can’t fully self-certify trust anymore. Third-party mentions, reviews, and citations function as external validation that AI systems weigh independently of what your own page claims about itself — which is exactly why digital PR and consistent publishing on International SEO Services and industry-specific subtopics compounds over time rather than producing an immediate spike.

Structured Data for AI Search

Schema markup has moved from a “nice-to-have” ranking signal to something closer to a prerequisite for reliable AI citation. One analysis of AI Overview selection rates found structured data markup associated with a 73% improvement in AI Overview selection rates, because citation algorithms scan schema to verify E-E-A-T signals before choosing sources. The same analysis found that <cite index=”15-

1″>pages with proper FAQ schema, structured author credentials, and explicit expertise markers consistently outperform equivalent pages without schema.

Priority schema types for ASO, in order of impact:

Article / BlogPosting schema — establishes author, publish date, and modified date (critical for the freshness signals covered above)
FAQPage schema — directly maps to the question-and-answer format AI Overviews and voice assistants prefer to extract
Author / Person schema — reinforces E-E-A-T by connecting content to a verifiable individual with credentials
Organization schema — establishes your brand as a consistent, recognizable entity across the web
BreadcrumbList schema — helps AI systems understand topical hierarchy and site structure
HowTo schema — where applicable, structures step-based content for direct extraction

Technical SEO Best Practices for AI Search

Structured content means nothing if AI crawlers can’t reach it. Technical accessibility is the foundation everything else sits on, and it’s consistently underestimated.

Confirm AI crawler access explicitly. GPTBot, PerplexityBot, Google-Extended, and ClaudeBot need to be allowed in robots.txt if you want to be eligible for citation on those platforms. As one guide puts it plainly: if a crawler can’t crawl or render your main content, your page is less likely to be available as a reliable citation candidate — technical accessibility matters as much as classic SEO signals in this environment.
Ensure content is server-rendered or pre-rendered. AI crawlers vary in their JavaScript execution reliability; heavily client-rendered content is a common, invisible failure point.
Fast Core Web Vitals still matter — slow, unstable pages get deprioritized in the initial retrieval pool before AI evaluation even begins.
Clean, semantic HTML (proper heading hierarchy, no keyword-stuffed alt text, real <table> markup for tabular data) makes passage extraction significantly more reliable.
Maintain a consistent, crawlable XML sitemap and submit it through Google Search Console — this remains the backbone of eligibility for Google’s AI systems specifically.
Publish an llms.txt file where feasible, signaling to AI crawlers which content on your site is most authoritative and citation-ready — an emerging but fast-growing convention referenced across recent GEO guidance.

This technical layer is exactly where Web Design & Development and SEO strategy have to work in lockstep — a beautifully designed site with poor crawlability is functionally invisible to AI search, no matter how good the writing is.

Content Strategies That AI Models Prefer

Across all three platforms, a clear content pattern emerges from the research above. Structure your content around these principles:

1. Answer First, Explain Second

Open every section with a direct, self-contained answer in the first one to two sentences, then expand with context, nuance, and examples. This satisfies Google’s BLUE-style extraction preference, ChatGPT’s “first-third of content” citation pattern, and Perplexity’s preference for unambiguous, extractable claims — simultaneously.

2. Write Passages, Not Just Pages

Because AI systems evaluate at the passage level, every H2 and H3 section should be able to stand alone and make sense if it were the only paragraph an AI model ever extracted from your page. Avoid pronouns and references that only make sense in the context of the paragraph before (“this approach,” “as mentioned above”) — restate the subject clearly each time.

3. Lead With Original Data and Specificity

Generic explanations get filtered out by information-gain checks. Original research, proprietary data, case studies, and named examples consistently outperform recycled definitions — this is true across Google AI Overviews, ChatGPT, and Perplexity alike.

4. Update on a Cadence That Matches Topic Volatility

A slow-moving evergreen topic can be refreshed quarterly. A fast-moving one — AI tools, algorithm changes, pricing, product comparisons — needs updates measured in days, not months, especially for Perplexity visibility.

5. Diversify Beyond Your Own Domain

Since earned third-party mentions carry independent weight with every platform studied here, a content strategy confined to your own blog has a structural ceiling. Pair on-site publishing with digital PR, guest contributions, and expert-source outreach (e.g., HARO-style platforms) to build the external citation signals that AI systems specifically look for.

Common AI SEO Mistakes

Treating ASO as a one-time project instead of an ongoing content operation. Freshness windows as short as 48–72 hours on fast-moving topics mean a “set it and forget it” article strategy quietly decays.
Burying the answer under a long introduction. With roughly 44% of ChatGPT citations pulled from the first third of a page, a slow, scene-setting opening is a direct visibility cost.
Chasing keyword density instead of entity clarity. AI systems evaluate topical relationships and meaning, not phrase-matching frequency — over-optimized, keyword-stuffed copy actively signals low quality.
Ignoring crawler access in robots.txt. A well-written, perfectly structured page that AI crawlers can’t reach never enters the evaluation pipeline at all.
Publishing without a named, credentialed author. Anonymous or generic “Admin” bylines undercut E-E-A-T at exactly the layer AI systems weight most heavily in 2026.
Assuming domain authority alone guarantees citations. Perplexity in particular rewards narrow topical depth over broad domain size — a strategy built purely around backlink volume misses this.
Duplicating what’s already ranking instead of adding information gain. Summarizing five competitor articles into a sixth, near-identical one is the single fastest way to be filtered out.

AI Search Optimization Checklist

Use this as a working audit for any page you want AI systems to cite.

AI citation tracking in place to measure actual performance, not just rankings

Best AI SEO Tools in 2026

The AI visibility tooling category matured quickly through 2025 and 2026. Rather than recommend specific vendors (the landscape shifts fast and claims should always be independently verified), here are the categories worth building into your stack:

AI citation trackers — tools that monitor whether and how often your brand is cited across ChatGPT, Perplexity, and Google AI Overviews for a defined set of target prompts, similar in spirit to traditional rank trackers but built for generated answers instead of ranked lists.
Schema validators and generators — tools that audit your structured data implementation against current schema.org standards and flag gaps in Article, FAQ, and Author markup.
Crawler log analyzers — tools that show whether GPTBot, PerplexityBot, and Google-Extended are actually reaching and rendering your content, not just whether robots.txt technically allows them.
Content freshness dashboards — tools that flag pages approaching their topic-specific staleness threshold before a competitor’s more recent update displaces you.
Digital PR and mention monitoring platforms — tools that track third-party citations and mentions, since earned media is one of the strongest predictors of ChatGPT citation share specifically.

Because this category evolves monthly, we recommend validating current tool capabilities directly against vendor documentation before purchasing — a step Pentox Studio builds into every SEO Services engagement.

Future of AI Search

A few directional shifts are already visible and worth planning around:

Preferred Sources will likely become a genuine ranking input, not just a display feature, as Google has stated this is an active area of development. Building a reader base that actively opts in to preferring your domain is a compounding asset, not a vanity metric.
Multi-modal retrieval will expand. As AI Overviews and AI Mode increasingly synthesize images, video transcripts, and structured tables alongside text, content that exists only as unstructured prose will fall further behind content built with proper markup across formats.
Agentic search will raise the bar on trust signals. As AI systems increasingly take actions on a user’s behalf (booking, comparing, purchasing) rather than just answering questions, the trust and verification bar for being cited as a source will almost certainly increase further, not ease.
The “trust cliff” between high- and low-authority domains may widen before it narrows, as AI systems remain risk-averse about attribution errors — making the earned-authority work described in this guide a compounding, not a one-time, investment.

Frequently Asked Questions

What is AI Search Optimization (ASO)?
AI Search Optimization is the practice of structuring and technically preparing website content so AI systems like Google AI Overviews, ChatGPT, and Perplexity can retrieve, evaluate, and cite it inside a generated answer, rather than simply ranking it in a traditional results list.

Is AI Search Optimization the same as GEO or AEO?
They overlap significantly and are often used interchangeably. GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization) both describe the same underlying goal as ASO: earning citations inside AI-generated answers rather than just search rankings.

Does traditional SEO still matter if I’m optimizing for AI search?
Yes. Technical crawlability, backlink authority, and topical relevance remain the foundation AI systems build their evaluation on top of. ASO adds a passage-level, freshness-sensitive, and structure-sensitive layer on top of traditional SEO — it doesn’t replace it.

How often do I need to update content to stay visible in AI search results?
It depends on topic volatility. Perplexity in particular can compress freshness windows to 48–72 hours for rapidly developing topics, while more evergreen subjects may only need quarterly reviews. Track your specific category’s rate of change rather than applying one fixed schedule.

Does domain authority guarantee citations in ChatGPT and Perplexity?
No, though it helps differently on each platform. ChatGPT shows a steep advantage for high-authority domains, while Perplexity has repeatedly cited smaller, topically focused sites over larger general publishers when the smaller site demonstrated deeper subject-matter authority.

What’s the single highest-impact change I can make for AI Search Optimization today?
Restructure your top-performing pages so each section answers its core question in the first one to two sentences, in a self-contained way. This single change aligns with how Google AI Overviews, ChatGPT, and Perplexity all extract passages, and it’s typically the fastest, lowest-cost improvement available.

Conclusion

AI Search Optimization isn’t a rebrand of SEO — it’s the next layer built on top of it. Google AI Overviews reward historical trust, freshness, and genuine information gain. ChatGPT rewards domain authority, BLUE-style structure, and earned third-party media. Perplexity rewards extractability, topical depth, and near-real-time freshness. The throughline across all three is consistent: clear, self-contained, well-structured, genuinely original content backed by verifiable expertise wins — regardless of which AI system is doing the evaluating.

Treat AI Search Optimization as an ongoing operating discipline, not a one-time audit. The sites winning AI citations in 2026 are the ones publishing consistently, structuring deliberately, and earning trust signals outside their own domain — not the ones that optimized a handful of pages once and moved on.
