How does Google choose which sites appear in AI Overviews and AI Mode?
Google picks supporting links for AI Overviews and AI Mode from its regular search index using its core ranking systems, so a page has to be indexed and eligible to show a snippet before it can be cited.
Google's documentation names two techniques. The first is retrieval-augmented generation, also called grounding: the system pulls relevant pages from the index and builds the answer from them, with links. The second is query fan-out: the model runs several related searches at the same time to cover sub-topics. Google's own example turns a question about a lawn full of weeds into searches about herbicides, removing weeds without chemicals and preventing them.
That second point matters most. You can be cited for a broad question because you have the clearest answer to one narrow sub-question inside it. Google also says there are no extra technical requirements and no special markup needed for AI features.
So we map the sub-questions around your main topics, the same way this section was built, and make sure each one has a direct answer on a page Google already indexes.

How does ChatGPT decide which websites to cite?
ChatGPT search rewrites the user's question into one or more search queries, sends them to third-party search providers, and cites pages from those results that answer the question.
OpenAI's help center describes the flow. A detailed question becomes a targeted query, and after reading the first results, ChatGPT may send more specific follow-up queries. It can also use general location to localize searches. OpenAI does not publish how it ranks what comes back.
The part you control is access. OpenAI's search crawler is OAI-SearchBot, and sites that block it in robots.txt will not appear in ChatGPT search answers beyond bare navigational links. GPTBot is a separate crawler for model training, so you can block training and still allow search. Check your firewall or CDN too, because bot protection can block these crawlers even when robots.txt allows them.
ChatGPT adds utm_source=chatgpt.com to referral links, so you can see that traffic in GA4. In my experience, the sites that get cited answer specific questions plainly and are talked about elsewhere.

How does Perplexity choose its sources?
Perplexity answers by searching the web, drawing on its own index built by PerplexityBot and on pages it fetches live while answering, then shows numbered citations next to its claims.
Its documentation separates the two. PerplexityBot crawls and indexes pages so they can be surfaced and linked in results, respects robots.txt and is not used to train models. Perplexity-User visits a page when someone asks a question, and because a person triggered the visit, Perplexity says it generally ignores robots.txt. If you block PerplexityBot, your full text stays out of its index, though it may still keep your domain, headline and a brief factual summary.
Perplexity also labels some cited domains as Government, Academic or Trusted. Its review asks plain questions: does the site correct its mistakes, does it say who wrote each piece, does it keep news separate from advertising and opinion. Most sites carry no label, and Perplexity says that is not a negative judgment.
Those questions make a good checklist for any business site. Put a named author on content, show when it was updated, and correct errors in public.

Do I need to rank on page one of Google to show up in AI answers?
Not for the exact question asked, but your page does need to rank well for something closely related, because Google's AI features are built on its core ranking systems.
Query fan-out is the reason. When AI Mode splits a question into several sub-searches, the pages it cites are the ones that do well on those sub-searches. A page stuck on page two for a broad head term can still be cited if it is the clearest answer to one specific follow-up. Google says these features show a wider and more diverse set of links than a classic results page.
ChatGPT and Perplexity work from their own crawlers and search partners, so your Google rank does not carry over directly. What carries over is being crawlable, being indexed and having pages that answer specific questions in plain words.
A quick check you can do today: take one service page and list the five follow-up questions a buyer asks before calling you. If the page answers none of them directly, that is the gap. Our SEO + GEO work fills it page by page.

Why does ChatGPT or Gemini get facts about my business wrong?
Usually because the information about your business on the web is thin, outdated or inconsistent, and the assistant fills the gap with whatever sources it finds.
AI assistants summarize what they retrieve; they do not check with you first. If an old directory lists a previous address, a review site shows outdated hours and your own About page never says who runs the company, the model blends those signals. OpenAI's own help center warns that search results and citations can be incomplete, outdated or incorrect.
The fix is unglamorous. Make one page on your site the clear source of truth for who you are, what you offer, where you work and who runs it, with Organization structured data that matches. Clean up old listings so they agree. Then earn mentions where people actually talk: industry sites, local press, Reddit, Quora and YouTube. I post on those channels myself because assistants read them.
Retest the same prompts every month. Corrections take time to show up, and they rarely come from your own site alone.

Can I opt out of Google AI Overviews without hurting my rankings?
Yes. Search Console now has a Search generative AI control that removes your site from AI Overviews, AI Mode and generative features in Discover, and Google says the setting is not used as a ranking signal for the rest of Search.
Google rolled the control out to all sites on August 31, 2026, under Settings in Search Console. Inclusion is the default. If you exclude your site, your links and content will not appear in those features or be used to ground AI answers, so you also get no impressions or clicks from them. Google notes that similar content from other sites can still show.
For most businesses I would not opt out. Buyers ask these questions in AI Mode whether you are there or not, and being absent hands the citation to a competitor. The exceptions are publishers whose content is the product, or pages where a summary would give away what you sell.
Before deciding, open the Generative AI performance report in Search Console and see what those features send you today.

Do Reddit, Quora and YouTube matter for AI search?
Yes. AI assistants pull from many sources beyond your website, and community sites like Reddit and Quora, plus YouTube, appear in AI answers often because they hold real people answering real questions.
That is the shift from classic SEO. Google ranks pages; assistants summarize answers. If your expertise lives only on your own site, you are one voice. If the same expertise shows up in a helpful Reddit thread, a Quora answer and a how-to video, the assistant sees agreement across sources, and agreement is what it trusts. Google even describes its fan-out searches as running across subtopics and data sources.
My rule is to post as a person, not a brand. Give step-by-step answers with real examples, say who you are, and link back only when it truly helps. The one-line replies you see in many subreddits, like telling someone to raise their budget, teach nobody and get cited by nobody.
This does not replace SEO. It is the next layer on top. Related reading: AI search has a citation problem.
