AI Search Optimization: What Google Changed in 2026

AI search optimization is the work of getting your business mentioned, cited and described accurately when Google AI Overviews, AI Mode, Gemini, ChatGPT, Perplexity, Claude and Copilot answer customers' questions. In practice that means checking what those engines say about you, keeping their search crawlers allowed, and answering customers' questions in plain text on your pages.

In 2026 Google added a Search Console report that counts impressions of your links in AI Overviews and AI Mode, plus a control that lets you exclude your site from Google's generative AI features. For you, that means your service pages can be excluded from AI Overviews and AI Mode while they still show in ordinary Search.

Key points

• Meeting Google's eligibility rules makes a page eligible for AI Overviews and AI Mode, not guaranteed a link.
• Search Console now reports impressions of your links in AI Overviews and AI Mode; as of August 2026, Search Engine Journal reported it had no click data.
• The new control can exclude your site from those features, so check no property or parent property is set to exclude.

Does meeting Google's requirements mean you'll be cited?

No. Google's 2026 AI optimization guide lists three requirements, and meeting them only makes a page eligible:

1. The page is indexed.
2. It's eligible to be shown with a snippet.
3. The property is included in Search generative AI features in Search Console, the default unless someone opted it out.

First check: in Search Console, open Settings, then Search generative AI, and confirm it says include. Even then, Google says "Indexing and serving aren't guaranteed."

What changed in AI search optimization in 2026?

What does Google say you need to do to appear in AI Overviews and AI Mode?

Google's AI features documentation, last updated in December 2025, says, "There are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary." Google's July 2026 guide adds one condition, the inclusion setting, and it's on by default, so the only new task is confirming nobody switched it off.

You don't need "new machine readable files, AI text files, or markup," and there's no special schema.org structured data to add. Google's best-practice list for AI features:

• Crawling allowed in robots.txt "and by any CDN or hosting infrastructure"
• Content findable through internal links
• A good page experience
• Important content available as text, supported by images and video
• Structured data that matches the visible text on the page
• Merchant Center and Business Profile information kept up to date

What does the Search Console generative AI report show?

Google's definition reads, "Impressions are how many times links to your site were shown to a user in a generative AI feature on Google Search." As of August 2026, the report's help page lists four ways to group the data, and none by query:

• Countries: where the search came from
• Devices: desktop, tablet or mobile
• Dates: days, weeks or months
• Pages: the final URL Google linked, after any redirects

As of its August 2026 report, Search Engine Journal said the report doesn't include click data. Google says sites appearing in AI features "are included in the overall search traffic in Search Console," so AI clicks are mixed into your normal Performance report.

A Pages export lists pages with recorded impressions in the date range you picked. Google assigns most of this data to the canonical URL, and the usual Performance report limits apply.

Hypothetical example: two of your pages are linked in the same AI Overview. The chart, which Google aggregates by property, counts one impression. The Pages table, aggregated by page, counts one for each page. So never add up page rows and treat the sum as the chart total; Google says the two totals can differ for this reason.

How does Google's report compare with Bing's?

Bing defines grounding queries as "the key phrases the AI used when retrieving content that was referenced in AI-generated answers," from "a sample of overall citation activity."

What does a missing page look like in practice?

Hypothetical example: a plumber's Pages export lists the homepage but not the water heater repair page. That shows missing data, not a diagnosed cause. The owner works in three stages:

1. Reporting limits: check the filters, impressions credited to another canonical URL, and the row limits.
2. Eligibility: the page is indexed, the applicable setting is include, and neither HTML nor headers carry nosnippet or max-snippet:0. If the regular Performance report shows no Search impressions for water heater queries, fix standard Search visibility first. Regular impressions without AI impressions still don't reveal a cause, since Google doesn't guarantee an eligible page will be shown.
3. Content: the page never says which heater types the plumber repairs or which towns it serves, the first things a caller asks. That gap is worth fixing whatever the report shows.

Should you use the Search generative AI control?

If you want customers to find you, leave it set to include. Google's control help page says that if you exclude your site, "links to your site and your site's content won't appear in Search generative AI features." Know three things first:

1. It is not a ranking signal. Google says the control "isn't used as a ranking or inclusion signal affecting other parts of Search."
2. It does not stop model training. For that, Google points to Google-Extended.
3. Properties inherit it. By default a property follows its closest ancestor that has its own setting configured, and the owner of a child property can override it for that section.

Google says that after you change the control, exclusion generally takes a few days.

How do you do AI search optimization for ChatGPT and Perplexity?

OpenAI's crawler documentation says, "Sites that are opted out of OAI-SearchBot will not be shown in ChatGPT search answers, though can still appear as navigational links." GPTBot is its training crawler, so you can block GPTBot and still allow OAI-SearchBot. Perplexity's documentation says PerplexityBot "is designed to surface and link websites in search results on Perplexity," isn't used to crawl for AI foundation models, and recommends allowing it in robots.txt.

A site that blocked every AI bot to stay out of training may have dropped out of ChatGPT search answers and shut out the crawler Perplexity uses for its search results.

How do you start AI search optimization this week?

Quick path for today: confirm the inclusion setting (step 1), then run URL Inspection and the step 4 checks on your most important service page, whether or not it appears in an export. The full list gives you the pages with recorded AI impressions, the important pages to investigate, and a crawler setup with no accidental blocks.

1. In Search Console, open Settings, then Search generative AI, and confirm the setting that applies to each property, inherited from a parent or set on its own, is include.
2. Open the generative AI performance report, group by Pages, and use its export button. If the report doesn't appear, Google says your site may not have enough AI impressions yet; list your most important service pages and go to step 3.
3. For each important page missing from the export, run URL Inspection. Its default result is Google's indexed version, not the live page: confirm the page is indexed and not blocked by noindex, and that the Google-selected canonical is that URL, then view the HTML Googlebot received.
4. Then check the current page, since it may have changed since the crawl. If you don't edit your site's code, hand this step and step 5 to your web developer.
5. HTML directives: no nosnippet or max-snippet:0 in the robots meta tag. Both stop the page's content being used as a direct input for AI Overviews and AI Mode.
6. Response headers: the same rules can sit in an X-Robots-Tag HTTP header, which doesn't show on the page.
7. Conflicting rules: the more restrictive one applies, so max-snippet:-1 won't undo nosnippet. See Google's robots meta tag specifications.
8. Check robots.txt and your CDN or firewall bot settings for blocks on Googlebot, Bingbot, OAI-SearchBot and PerplexityBot.
9. Where a key page leaves a specific customer question unanswered, answer it in plain text near the top. Google says you don't need to write a special way for AI.
10. Verify the site in Bing Webmaster Tools and read the grounding queries in AI Performance.

FAQ

Is AI search optimization different from SEO?

For Google, mostly not, since Google says the same foundational SEO practices apply. The difference is that ChatGPT and Perplexity use their own search crawlers. ChatGPT search won't show a site opted out of OAI-SearchBot except as a navigational link, and Perplexity recommends allowing PerplexityBot.

Will opting out of AI Overviews hurt my regular Google rankings?

Google says the Search generative AI control isn't used as a ranking or inclusion signal for other parts of Search. What you give up is the AI Overviews, AI Mode and Discover AI placements.

What should I do if my site has no generative AI report?

Google's help page lists two reasons: the site hasn't had enough impressions in generative AI features, or it has been excluded. The same page says the report reached all websites worldwide on August 31, 2026. Check the control first, because exclusion is the one you can change yourself. Steps 3 and 4 check for common eligibility blockers; passing them doesn't prove a page is eligible or explain why the report is missing.
