Is SEO Still Relevant With AI Answers?

Most AI engines don't find pages by magic. A crawler fetches the page, an index stores it, a retrieval step pulls it into the model's context, and the model writes the answer. If the first two steps fail, nothing after them can help.

Google is explicit about its own AI surfaces. Its AI features documentation says: "To be eligible to be shown as a supporting link in AI Overviews or AI Mode, a page must be indexed and eligible to be shown in Google Search with a snippet." The same page adds that there are no additional technical requirements and no special optimizations needed.

That means the work that keeps a page indexable on Google is the same work that makes it eligible for Google's AI answers. Eligible is not the same as included, though. Google also says indexing and serving isn't guaranteed.

So SEO stays relevant as a prerequisite, not as a promise. For a broader look at which SEO practices carry over, see SEO in the age of AI.

It helps to split the process into four stages, because SEO touches some of them and not others.

• Parametric. What the model knows with no web access, frozen at its training cutoff. Nobody changes this in the current quarter.
• Access. Whether a crawler may fetch and store your page. You and your CDN control this.
• Retrieval. Whether your page enters the model's context for a given query. The engine controls this, and you influence it only partly.
• Generation. Which retrieved pages the model uses and cites. The model controls this.

Technical SEO lives almost entirely in the access stage, and access feeds retrieval. That is why it still matters.

One more caveat: retrieval is discretionary. As of October 2026, Google AI Overviews don't trigger on every query, and ChatGPT decides per question whether to search. When an engine answers without searching, nothing on your site is in play for that answer.

The old rule was simple: rank in the top 10 and you get the traffic. AI answers break that link.

Ahrefs found that 37.9% of URLs cited in Google AI Overviews also appeared in the first 10 results, in a study published in March 2026. Roughly 31% of citations came from positions 11 to 100, and roughly 31% from beyond position 100. Ahrefs changed its method between studies, so don't read its older, higher figure as a measured decline. The March figure is the one to use.

Three things explain the gap.

• Engines rewrite the query. OpenAI says ChatGPT search rewrites a prompt into one or more targeted queries. Google may fan out across subtopics. The query you rank for may not be the query the engine ran.
• Position inside the context matters, but you can't set it. C-SEO Bench found that a document's position in the model's context drives citation far more than rewriting tricks. That position was set by the researchers, not earned through ranking.
• Fit to the question matters. Research keeps pointing to topical relevance as one of the most reproducible factors, and that is not the same as keyword coverage.

The practical read: rank is still a useful signal that a page is indexed and relevant. It's just not a forecast of citation. The Is SEO dead? guide covers what that shift means for reporting.

A public experiment by OtterlyAI shows the index link clearly. Otterly published about 1,000 AI-generated posts on each of two new domains and tracked them for roughly four months.

• Google deindexed one site after about 14 days and the other after about 90, with no manual action reported in Search Console.
• After the removal, Google AI Overviews, AI Mode and Gemini almost never cited either site.
• Bing never deindexed them. Microsoft Copilot, which grounds on Bing, produced 2,718 of the 3,934 citations Otterly tracked for one of the sites.
• ChatGPT cited them effectively zero times, even while they ranked in Bing.

Two lessons follow. An engine cannot cite what its index no longer holds. And being indexed somewhere is necessary but not enough: ranking in Bing did not translate into ChatGPT citations here.

The test has limits. It ran one site per arm, on a low-competition topic, and a tracking vendor ran it. Treat it as a clear illustration, not a general law. If Copilot matters to you, understand how Bingbot reaches your site.

The levers with real evidence behind them mostly work by removing blocks. Here is how the main factors split.

The bottom half of the table is where most frustration comes from. No change to your site sets how an engine rewrites a query or orders its sources.

Work through these in order. Each step removes a reason an engine can't use your page.

1. Check rendering. Vercel found that ChatGPT and Claude crawlers fetch JavaScript files but don't execute them, so they can't read client-side rendered content. Googlebot renders; most AI crawlers don't. Compare your raw HTML with the rendered page and move anything important into the server response.
2. Check robots.txt per bot. OpenAI's crawler page says each setting is independent. GPTBot governs training. OAI-SearchBot governs ChatGPT search. A blanket AI block can remove you from ChatGPT search without anyone noticing. Read whether to block GPTBot before you edit anything. A minimal allow rule looks like this:

User-agent: OAI-SearchBot
Allow: /

3. Check the network layer. OpenAI says eligibility means allowing OAI-SearchBot and confirming your host or CDN allows its published IP addresses. A firewall can return 403 to a crawler robots.txt allows. Since 2026-09-15, Cloudflare blocks its Training and Agent crawler categories by default on ad-displaying pages for new domains and existing free-tier customers, so recheck even if you changed nothing. The AI Crawler Checker requests a page as each AI crawler and shows which ones get turned away.
4. Remove accidental suppression. Look for noindex, nosnippet, max-snippet:0 and data-nosnippet left over from templates. In Search Console, confirm the property hasn't opted out of AI features. Inclusion is the default, but child properties inherit the parent's setting.
5. Check index status engine by engine. Use Google Search Console and Bing Webmaster Tools separately. One being healthy tells you nothing about the other.
6. State facts plainly. A specific price, number or one-line definition on a fetchable page gives an engine a sentence it can quote.
7. Get named where engines look. When engines cite other sites instead of yours, being mentioned on those sites is associated with appearing in the answer. See whether backlinks still matter.

Once the gates are open, measure. The free checker on this site shows whether AI engines name you for three buyer questions, as a snapshot.

• Reading rank as citation. A top-3 ranking says your page is indexed and relevant. It doesn't say an AI answer will cite it.
• Allowing GPTBot to get into ChatGPT. GPTBot controls training use only. ChatGPT search uses OAI-SearchBot.
• Trusting robots.txt alone. It's necessary but not sufficient. A WAF or CDN can block a crawler your file allows.
• Adding markup as an AI lever. Google says structured data isn't required for generative AI search, and its optimization guide says Search ignores llms.txt. Ahrefs' matched test found AI Overview citations fell 4.6% after pages added schema. Existing markup does no harm, so there's no need to remove it. It's just not a lever.
• Rewriting for AI. Google says you don't need to write in a specific way for generative AI search, and it rejects chunking as a requirement.
• Mass-publishing thin pages. In the Otterly test, Google removed both sites silently. Copilot citations did not replace Google.
• Chasing an AI rank. As of October 2026, Google's generative AI report shows impressions only, with no position data. Any "AI rank" for Google has nothing to be checked against.

Does ranking first on Google guarantee an AI Overview citation? No. Ranking shows your page is indexed and relevant, which makes it eligible. Google says indexing and serving isn't guaranteed, and AI Overviews don't trigger on every query. Ahrefs found that 37.9% of URLs cited in AI Overviews appeared in the top 10 results, so most citations came from pages ranked lower. Treat rank as a proxy for eligibility, not a forecast.

Do I need schema or an llms.txt file to appear in AI answers? No evidence says either one gets you cited. Google says structured data isn't required for generative AI search and that Google Search ignores llms.txt. No other engine documents reading llms.txt. Ahrefs' matched test found AI Overview citations fell 4.6% after pages added schema. Keep existing markup if you have it, since it does no harm, but spend your time on access fixes.

If Google deindexes my site, can other AI engines still cite it? Yes, if they draw on a different index. In Otterly's experiment, Microsoft Copilot, which grounds on Bing, kept citing two sites after Google removed them, while Google's own AI features almost never did. That is one test with one site per arm. The practical lesson is to check index status in each search engine separately.

Does Bing matter more now? It matters for Microsoft Copilot and Bing's AI summaries, which are backed by Bing's index. OpenAI says ChatGPT search sometimes partners with other search providers, but no source measures how much Bing presence affects ChatGPT. In Otterly's test, ranking in Bing produced effectively zero ChatGPT citations. Verify your site in Bing Webmaster Tools and treat it as its own channel.

Can I track my position inside Google's AI answers? Not with first-party data. As of October 2026, Google's generative AI report in Search Console shows impressions only, with no clicks, click-through rate or position. Google also says third-party tools don't have access to its internal ranking data. Track presence and citations per engine instead, and be clear which numbers are measurements and which are estimates.
