The Google vs AI Gap

Why Your Business Appears in Google But Not in AI Search

This is one of the most common situations I come across. The SEO is working. Google is showing the business. But type the same question into ChatGPT or Perplexity "” nothing. Here's why that happens.

The short answer: Google and AI use completely different systems

Google crawls your website, analyses it, and ranks it against other websites. That's what SEO optimises for.

ChatGPT doesn't use Google. It uses training data "” information it absorbed before a cutoff date "” plus Bing for some queries. Perplexity does live web searches but through its own index. Google AI Overviews pull from Google's index but specifically favour structured, cited sources, not just ranked pages.

Ranking well in Google tells you nothing about your standing in any of these systems. They're measuring different things.

How each AI system decides what to show

Google AI OverviewsPartially linked to SEO

Uses Google's index "” so pages Google has crawled can appear. But it prioritises pages with structured data, clear answers, and sources it can cite. A ranked page with no schema markup and no FAQ content is less likely to appear than a lower-ranked page that has both.

What helps: Schema markup, FAQ content, strong E-E-A-T signals, clear concise answers to common questions.

ChatGPTNo connection to Google SEO

Based on training data with a knowledge cutoff. Knows about businesses and brands it encountered frequently in that training data. A locally well-ranked business with no external mentions, press, or citations is unlikely to be in the training data at all.

What helps: External mentions, press coverage, directory listings, Wikipedia-adjacent sources, being referenced in content others write.

PerplexityPartial overlap with SEO

Does live web searches via its own index. Favours sources it considers authoritative and citable. A business website can appear here, but Perplexity tends to favour well-structured pages with clear, direct answers "” not marketing copy.

What helps: Direct answer content, schema markup, authoritative domain signals, factual tone.

Microsoft CopilotBing-based

Uses Bing's index rather than Google's. A business well-optimised for Google but not verified in Bing Webmaster Tools may rank poorly in Bing "” and therefore poorly in Copilot answers.

What helps: Bing Webmaster Tools verification, schema markup, Bing Business profile, same content signals as Perplexity.

What to do about it

The good news is that the fixes for AI visibility mostly improve your overall online presence anyway. None of them require undoing what you've already done for SEO.

📄

Add schema markup

Structured data gives all AI systems a machine-readable description of your business. It's the single highest-impact change for most small businesses.

📍

Directories, trade bodies, local press, review platforms "” every mention that corroborates your business across the web builds the entity AI systems trust.

💬
