When ChatGPT, Claude, Perplexity or Google’s AI features get your name, location, services or ownership wrong, the cause is usually not a secret “GEO score”. It is almost always that the systems that ground answers cannot see a clear, consistent, crawlable picture of you — or they see several pictures that disagree.
Checked against vendor documentation on 13 October 2026. We only list causes we can source. Fixing them does not guarantee correct answers; assistants still decide what they say.
If the bots that build AI search indexes are blocked in robots.txt (or by a CDN/firewall “block AI bots” rule), those systems never get your current pages.

How to check: our AI crawler guide and the free check both look at whether AI search bots are disallowed.
Assistants that ground on the web need a place that states who you are in plain text: legal name, trading name, what you do, where you are, how to contact you.

How to check: paste your About page into the free check; it looks for visible business facts and Organization/WebSite JSON-LD.
Google says its generative AI features on Search can show what is being said about products and services across the web, including blogs, videos and forums, and that AI systems look at a variety of sources. OpenAI and Anthropic search bots index public pages; they are not limited to your homepage.
So if directories list an old address, a press page uses a former company name, or a social profile still says “freelance designer” after you incorporated, an assistant may mix those sources. Markup on your site helps machines read your site; it does not rewrite every other page about you.

Honest limit: vendors do not publish a checklist titled “conflicting NAP causes wrong ChatGPT answers”. The mechanism we can verify is multi-source retrieval. Cleaning your own pages and high-signal profiles is the controllable part.
Google’s generative AI guide describes retrieval-augmented generation that relies on core Search systems to fetch relevant, up-to-date pages for fresher answers. Its structured-data quality guidelines also say to provide up-to-date information. If your live site is correct but an old “Services” URL, PDF or mirror still ranks and gets retrieved, answers can lag.

Practical steps that stay inside vendor advice: update or remove outdated pages, use normal redirects/canonicals, keep Business Profile details current, and allow recrawl time after changes.
Google’s AI-features best practices say structured data should match the visible text on the page. The general structured-data guidelines forbid marking up content that is not visible to readers, and say misleading or non-representative markup can make rich results ineligible.
Wrong JSON-LD (old phone in schema, different legal name than the About heading) does not “hack” AI answers into correctness. It adds another conflicting signal.

Search Console has a Search generative AI control. Excluding your site prevents your content from appearing in AI Overviews, AI Mode and related generative features (including as grounding links). That is intentional absence, not a “wrong description” — but it looks the same to you if customers ask Google AI and never see your site.
