AI SEO: How to Rank in ChatGPT, Gemini and Google AI Overviews (2026 Guide)
AI SEO is how your business gets cited when buyers ask ChatGPT, Gemini, Perplexity or Google AI Overviews instead of scrolling search results. Here is how each engine picks sources and the practical checklist we use with clients.
AI SEO is the work of making your business easy for AI answer engines (ChatGPT, Gemini, Perplexity and Google AI Overviews) to find, understand, trust and cite when someone asks a question you should be the answer to. In practice it is good SEO plus a few new habits: clear facts about your brand, answer first pages, structured data, mentions on other trusted sites, and letting the right AI crawlers in.
If you already work with an SEO company in Bangalore or run SEO in house, you are not starting from zero. This guide shows what actually changes, how each engine picks its sources based on what the platforms themselves have published, and the checklist we use at Nuwizo for clients who want to show up when buyers ask AI instead of typing into Google.
What is AI SEO, in plain words?
A founder in Koramangala asks ChatGPT “which payroll software works for a 40 person startup in India”. A parent in Whitefield asks Google “paediatric dentist near me open on Sunday” and reads the AI Overview before scrolling. Neither sees ten blue links first. They see a written answer with a handful of sources.
AI SEO (also called answer engine optimization, AEO, AI search optimization or LLM SEO) is the practice of being one of those sources. The names overlap a lot. Generative engine optimization, or GEO, is the broader idea, and we covered the strategy side of it in our post on GEO vs SEO and the shift to generative engine optimization. This article is the practical companion: what to actually change on your site and outside it, this quarter.
Here’s the honest part. There is no secret AI algorithm to hack. Each of these tools leans on a search index (Google’s, Bing’s or its own) and picks pages that answer clearly and look trustworthy. The foundation is still classic SEO. What changes is your content format, how much your brand is talked about elsewhere, and a few technical switches.
How each AI engine picks its sources
Google AI Overviews and AI Mode
Google is unusually direct. Its official guidance on AI features says there are no additional requirements to appear in AI Overviews or AI Mode, and no special optimizations necessary. You don’t need new machine readable files, AI text files or special markup. A page simply has to be indexed and eligible to show a snippet in normal Google Search.
The same page explains that AI Overviews and AI Mode can use a “query fan out” technique: Google runs several related searches across subtopics and then pulls supporting links from all of them. So a page that ranks fifth for a narrow sub question can still get cited in the overview for a broader query. Google’s own best practices read like a normal SEO checklist: allow crawling, use internal links, give a good page experience, keep important content in text, make structured data match visible text, and keep Merchant Center and Business Profile details current.
To keep content out of these features, Google points you to the existing controls: nosnippet, data-nosnippet, max-snippet and noindex. Blocking the Google-Extended token does not remove you from AI Overviews, because AI Overviews are part of Search and are crawled by Googlebot.
ChatGPT search
OpenAI runs separate crawlers for separate jobs, and its crawler documentation spells them out. OAI-SearchBot is the one that finds and surfaces sites in ChatGPT search answers. Sites that block it won’t be shown in those answers, though they can still appear as a bare link and title. GPTBot collects content that may be used to train OpenAI’s models. ChatGPT-User fetches a page when a person asks ChatGPT to look at it, so normal robots.txt rules may not apply to it.
OpenAI’s publisher FAQ also says it can pick up URLs from a third party search provider, and Microsoft has been ChatGPT’s publicly announced search partner since 2023. That’s why we push clients to take Bing seriously now (more on that below). One useful detail for tracking: ChatGPT adds utm_source=chatgpt.com to the links it sends, so those visits show up clearly in GA4.
Perplexity
Perplexity keeps its own index. Per its crawler documentation, PerplexityBot crawls to surface and link websites in Perplexity’s answers and is not used to train foundation models. Perplexity-User visits a page live when a user’s question needs it, and generally ignores robots.txt because a human triggered the fetch. Its numbered citations often send small amounts of very high intent traffic.
Gemini
Gemini grounds answers that need live web information in Google Search and shows inline source links. So if you do well in Google’s index and answer the question cleanly, you’re in the pool Gemini draws from. Google’s crawler docs say the Google-Extended token lets you limit how your content is used for training and grounding in Gemini apps and some other Google AI products, and that it does not affect your inclusion or ranking in Google Search.
Classic SEO vs AI SEO signals
Most of the old work still counts. Here’s how we explain the difference to clients.
| Area | Classic SEO focus | What AI SEO adds |
|---|---|---|
| Goal | Rank a page in the top 10 and win the click | Get your brand or page cited inside the answer, even if fewer people click |
| Content format | Long pages built around a keyword | Answer first paragraphs, clear definitions, short sections that can be quoted on their own |
| Keywords | Head terms and long tail phrases | Full conversational questions, comparisons and “best X for Y” prompts |
| Authority | Backlinks and domain strength | Brand mentions, reviews, listicles and directories, linked or not |
| Entity data | Nice to have | Essential: consistent name, address, category, founders and services everywhere |
| Structured data | Used for rich results | Still useful for clarity, but must match what is visible on the page |
| Search engines | Mostly Google | Google plus Bing (feeds ChatGPT) plus Perplexity’s own index |
| Crawlers | Googlebot and Bingbot | Also OAI-SearchBot, GPTBot, PerplexityBot and the Google-Extended token |
| Measurement | Rankings, clicks, conversions | Citations, AI referral traffic, brand search growth, share of answers |
The AI SEO checklist we use with clients
The first four are on your own site and cost little. The rest take longer but drive most of the AI visibility.
1. Make your entity unmistakable
AI models need to be sure who you are. If your Google Business Profile says “Sharma Dental Care”, your website says “Sharma Dental Clinic” and JustDial says “Dr Sharma’s”, you’ve made yourself three half brands. Pick one name and use it everywhere. Write a clear About page that states what you do, where you operate, who founded the business and since when. Keep the same phone, address and services across your site, Google Business Profile, LinkedIn, JustDial or IndiaMART, and marketplaces like Amazon.in or Flipkart.
2. Add structured data that matches the page
Use Organization or LocalBusiness schema on the home page, Product schema on product pages, Article schema on blogs, and FAQ markup where you genuinely have questions and answers. Google is clear that it gives no special AI boost for markup, but structured data removes ambiguity, and ambiguity is what gets you skipped. The rule that matters: the markup must say exactly what the visible page says. Prices, ratings and addresses that don’t match are a fast way to lose trust.
3. Write answer first
Every important page should answer its main question in the first one or two sentences, in plain words. Then explain. Then add detail. AI engines love a paragraph that still makes sense when lifted out. Name the city, the price range, the timeline. “We deliver across Bengaluru within 24 hours for orders placed before 2 pm” beats “we offer fast delivery”.
4. Build FAQ sections from real questions
Pull questions from your sales calls, WhatsApp chats, Google’s “People also ask” box and the autocomplete in ChatGPT itself. Answer each in two to four sentences. A real estate developer should cover RERA registration, possession dates, loan tie ups and maintenance charges, because buyers ask AI tools exactly that before a site visit.
5. Earn brand mentions and reviews
This is the part most brands skip, and honestly it’s the one that moves AI answers the most in our experience. When ChatGPT or Perplexity recommends “the best interior designers in HSR Layout”, it’s summarising what the web already says. If nobody else mentions you, you’re invisible. Get reviews on Google, Practo, Zomato or wherever your category lives, and reply to them. Pitch founder quotes to Indian business publications. Our guide to off page SEO covers the link side of this; for AI, unlinked mentions count far more than they used to.
6. Get onto the lists and directories AI reads
Ask any AI tool “top CRM software in India” and look at the sources. You’ll see listicles, comparison sites, G2 or Capterra pages, Reddit threads and industry directories. Find the 15 to 20 pages that keep getting cited for your category and work out how to get on them: submissions, review campaigns, partnerships, or a good pitch to the editor.
7. Don’t ignore Bing (it feeds ChatGPT)
Set up Bing Webmaster Tools, submit your sitemap, and turn on IndexNow if your CMS supports it (most WordPress SEO plugins do). Check that your key pages are actually indexed in Bing. We often find Indian sites that rank fine on Google but are half missing from Bing.
8. Decide your AI crawler policy in robots.txt
This is a business decision, not just a technical one. Here are the main user agents and the tradeoffs.
| User agent | What it does | If you block it | Our usual advice |
|---|---|---|---|
| Googlebot | Crawls for Google Search, including AI Overviews and AI Mode | You disappear from Google entirely | Always allow |
| Google-Extended (token) | Controls use of your content for training and grounding in Gemini apps and some other Google AI products | No effect on Search ranking, but less presence in Gemini answers | Allow for most businesses that want leads |
| OAI-SearchBot | Finds pages for ChatGPT search answers | You won’t be cited in ChatGPT search answers | Always allow if you want AI visibility |
| GPTBot | Collects content that may train OpenAI models | Content not used for training; search visibility unaffected | Allow for marketing sites; publishers with paid content may block |
| PerplexityBot | Indexes pages for Perplexity answers | You drop out of Perplexity citations | Allow |
For a typical service business or D2C brand, you want to be recommended, so let them in. A publisher or course seller with paywalled content may reasonably block GPTBot while allowing OAI-SearchBot. Also check your CDN or firewall: we’ve seen Cloudflare bot settings quietly block AI crawlers that robots.txt allowed.
9. Keep the site fast and easy to crawl
Heavy JavaScript that hides your main text, pages that take six seconds to load on a Jio connection, and content locked inside images or PDFs all hurt your chances. Our post on page load speed for SEO covers the fixes we usually start with.
How to measure AI visibility
There is no single “AI rankings” report yet, so we combine a few signals every month.
- Build a prompt list. Write 20 to 50 questions your buyers actually ask, such as “best ecommerce agency in Bangalore for Shopify” or “how much does a 2 BHK interior cost in Whitefield”. Mix brand, category and comparison prompts.
- Test them in each engine. Run the list in ChatGPT, Gemini, Perplexity and Google (look for AI Overviews and AI Mode). Use a fresh, logged out session. Note if you’re mentioned, cited with a link, or missing, and who is cited instead.
- Track AI referral traffic in GA4. Create a channel group or exploration for sources like chatgpt.com, perplexity.ai, gemini.google.com and copilot.microsoft.com. ChatGPT’s utm_source tag makes this easier.
- Watch Search Console. Google reports AI Overview and AI Mode clicks inside the normal Performance report under the Web search type, so look for impressions rising on question style queries even when clicks stay flat.
- Watch branded search. When AI tools recommend you, people often search your name directly afterwards. A steady rise in brand impressions is a good sign.
- Ask your leads. Add “ChatGPT or another AI tool” as an option in your “how did you hear about us” field.
Answers vary by day and by person, so judge trends over a quarter, not one screenshot.
What not to do
- Don’t publish hundreds of AI written pages. Thin, generic content is exactly what answer engines are built to skip, and Google’s spam policies still apply.
- Don’t stuff fake FAQs or fake reviews. Markup that doesn’t match the page, or reviews you wrote yourself, can cost you trust with Google and with buyers.
- Don’t rely on llms.txt or other “AI files” as a strategy. Google says it doesn’t need them. They don’t hurt, but they won’t fix weak content or a brand nobody mentions.
- Don’t block AI crawlers by accident. Check robots.txt and your firewall rules after every site migration.
- Don’t abandon classic SEO. Google still sends most of the traffic for most Indian businesses, and good rankings feed the AI answers too.

Frequently asked questions
What is the difference between AI SEO and traditional SEO?
Traditional SEO aims to rank a page and win the click. AI SEO aims to get your brand cited inside the answer that ChatGPT, Gemini, Perplexity or Google AI Overviews write. The foundations are the same, but AI SEO puts more weight on answer first content, consistent entity data and mentions on other trusted sites.
How do I rank in ChatGPT?
Make sure OAI-SearchBot is allowed in robots.txt, get your pages indexed in Bing, and write pages that answer specific questions clearly. Then build mentions on the lists, reviews and directories ChatGPT tends to cite for your category. There’s no paid placement or submission form for ChatGPT search answers.
How do I appear in Google AI Overviews?
Google says there are no extra requirements: your page must be indexed and eligible for a snippet in normal Search. In practice, pages that answer the question directly, have strong rankings for related sub questions and come from trusted sites get cited most. Structured data that matches the page and an updated Business Profile help too.
Should I block GPTBot on my website?
Blocking GPTBot only stops your content being used to train OpenAI’s models; it doesn’t remove you from ChatGPT search, which uses OAI-SearchBot. Most businesses that want leads leave both allowed. Publishers with paid or original research content sometimes block GPTBot and keep OAI-SearchBot open.
How long does AI SEO take to show results?
On page fixes like answer first rewrites, schema and Bing indexing can show up within weeks. Brand mentions, reviews and list placements take three to six months to build and longer to show consistently across AI tools.
