Perplexity vs ChatGPT vs Google AI Mode: who cites local agents?

All three will cite a local insurance agent, and none of them favors agents as a category. The difference is what each one reads before it answers. ChatGPT search reads pages its own crawler, OAI-SearchBot, is allowed to fetch, often after running your question through a partner search engine. Perplexity does a live web search on every question and links numbered sources it fetched with PerplexityBot. Google AI Mode works from Google's ordinary search index plus your Business Profile, and Google says it needs nothing extra from you. So the useful question isn't "which AI should I optimize for." It's whether your site gives all three something they can fetch, quote, and confirm. Here is what each operator documents.

The short version, side by side

How ChatGPT search picks what to cite

OpenAI's crawler documentation names three agents. OAI-SearchBot is used to "surface websites in search results in ChatGPT's search features," and sites that disallow it "won't appear in ChatGPT search answers." GPTBot crawls "content that may be used in training our generative AI foundation models." ChatGPT-User fetches a live page for "certain user actions," and robots.txt rules "may not apply" to it. Source: OpenAI crawler overview.

The help page adds the eligibility rules. Any public website can appear, but it must allow OAI-SearchBot in robots.txt and the host or CDN must admit OpenAI's published searchbot IP addresses. Results are ranked using "multiple factors," "placement is not guaranteed," and ChatGPT search "sometimes partners with other search providers," rewriting your question into targeted queries it sends to them. Source: Searching the web with ChatGPT.

• ChatGPT has no business directory of its own. It cannot read your Google Business Profile; whatever it knows about your agency came from a page on the open web. If your site is the only page stating your license, service area and lines of business plainly, that is what it quotes.
• The partner search index matters. OpenAI doesn't name its providers; outside analyses generally point at Bing. Submit your sitemap to Bing Webmaster Tools and confirm your county pages appear there.
• Allowing the bot isn't the same as letting it in. Managed firewalls on many hosts challenge unknown bots by default, so a site can allow OAI-SearchBot in robots.txt and still block it one layer down. Our post on which AI crawlers to allow covers the robots.txt side.

How Perplexity picks what to cite

Perplexity draws the same training-versus-search line. PerplexityBot "is designed to surface and link websites in search results on Perplexity. It is not used to crawl content for AI foundation models." Perplexity recommends allowing it in robots.txt and "permitting requests from our published IP ranges," and says changes can take up to 24 hours to register. Perplexity-User visits a page when "users ask Perplexity a question" and may "include a link to the page in its response"; because a person requested it, "this fetcher generally ignores robots.txt rules." Source: Perplexity crawlers.

On the answer side, Perplexity searches the web in real time for each question and cites what it used. Some citations carry a small shield icon, which Perplexity says marks a domain its source review process has rated as Government, Academic, or Trusted. Source: Understanding source labels. An agency site won't earn a shield; the lesson is that Perplexity grades provenance visibly. A county page that quotes a CMS enrollment figure and links cms.gov reads as a page built on a Government-labeled source; "thousands of local seniors trust us" reads as an assertion with nothing behind it. Our guide to Medicare enrollment data by county shows which federal files to quote.

One honest caveat: Perplexity does not publish how it weighs directories, review platforms, or local press for "who does X near me" questions. Third-party studies report it leans on directories and review sites for local queries; treat that as directional, be listed consistently, and make your own site the best page about you.

How Google AI Mode picks what to cite

Google is the most explicit of the three, and the most boring, which is a compliment. Its site-owner guide says: "There are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary." A page must meet the normal technical requirements, be indexed, and be eligible to show a snippet. Google says these features use "query fan-out," "issuing multiple related searches across subtopics and data sources," to "display a wider and more diverse set of helpful links." Source: AI features and your website.

Google's optimization guide, last updated July 10, 2026, is just as blunt about markup: "Structured data isn't required for generative AI search, and there's no special schema.org markup you need to add." It then points to the one thing the other two assistants don't have: "Using products like Merchant Center and Google Business Profiles can help your products and services to be visible in both AI responses and other Google Search results." Source: Google's guide to optimizing for generative AI features. We still put schema on every page we build, because "not required" isn't "ignored," but don't let anyone sell you "AI Mode schema." It doesn't exist.

Google is also the only one that will tell you whether it's working. On June 3, 2026 it announced Search Generative AI performance reports in Search Console, showing impressions, pages, countries, devices and dates for AI Overviews and AI Mode, and on August 31, 2026 it noted the reports had reached all websites worldwide.

Which one matters most for an insurance agent?

Google, on reach alone. AI Mode and AI Overviews sit inside the search box the people in your county already use, and Google is the only operator that hands you a report. Perplexity is the smallest audience, but it makes citations most visible, so it's the cheapest test of whether your pages are quotable at all.

We don't tell agents to pick one because the inputs overlap almost entirely: fetchable pages, indexed somewhere, unambiguous about who you are, shaped like an answer. The AEO guide for insurance agents is the long version of that sentence; the what you get page is how we build it in by default.

What to do on your site this week

1. Read your robots.txt. Confirm Googlebot, OAI-SearchBot and PerplexityBot are allowed. Decide about GPTBot separately; it doesn't affect citations either way.
2. Check the firewall. Look for bot-blocking or AI-scraper settings at your host or CDN and confirm the search crawlers get a 200, not a challenge page.
3. Open Search Console and Bing Webmaster Tools. Note which pages already appear in Google's generative AI report, and confirm your county pages are indexed in Bing.
4. Reconcile the facts. Name, address, phone, NPN, service area: identical on the site, the Business Profile, and every directory you control. Consumer-facing Medicare pages still need the "we do not offer every plan available in your area" language and the non-affiliation disclaimer; confirm wording with your FMO.
5. Run the prompt test. Ask all three assistants who helps with Medicare in your county and compare what they cite. Our 10-minute test gives you the prompts.

Frequently asked questions

Does ChatGPT use Google Business Profile?

Not directly. ChatGPT has no business listings of its own; OpenAI documents that ChatGPT search reads public web pages through its OAI-SearchBot crawler and sometimes sends rewritten queries to other search providers. Your Business Profile reaches ChatGPT only when the same facts appear on pages it can fetch, so keep name, address, phone and license identical on your site and every directory.

How does Perplexity find local businesses?

Perplexity runs a live web search for each question and links numbered sources in the answer. Its documentation says PerplexityBot exists to surface and link websites in Perplexity search results, and Perplexity-User fetches a page on demand when a user's question needs it. A local business appears when its own site, or a directory or review page about it, is fetchable and directly answers the question.

Do I need special schema markup to show up in Google AI Mode?

No. Google's documentation says there are no additional requirements to appear in AI Overviews or AI Mode, that structured data is not required for generative AI search, and that there is no special schema.org markup to add. The requirement is that a page is indexed and eligible to show a snippet. Schema still makes your identity unambiguous and qualifies pages for rich results, but it is not the gate.

Which AI search cites local businesses the most?

No operator publishes citation counts by business type, so any ranking is an outside estimate. Third-party studies tend to report that Perplexity lists more sources per answer than ChatGPT and leans on directories and review platforms for local questions, while Google's AI features reach the most people because they sit inside Google Search. Google is the only one you can measure for your own site without server logs.

Can I see which AI assistants are citing my website?

For Google, yes. Search Console's Search Generative AI performance report, rolled out to all sites on August 31, 2026, shows impressions, pages, countries, devices and dates for AI Overviews and AI Mode. ChatGPT and Perplexity offer no equivalent, so check server or CDN logs for their user agents and watch for referrals from chatgpt.com and perplexity.ai in analytics.
