ChatGPT Visibility Checker

ChatGPT doesn't have one "index" the way Google does. It decides whether to name your business from two completely separate systems, and a visibility check is only meaningful if it looks at both.

• Trained memory (the frozen layer). Everything the model absorbed before its knowledge cutoff. If your brand was mentioned widely and consistently across the web before that date, ChatGPT can recall you with browsing switched off. This layer can't be edited on demand - you can't email OpenAI to add yourself. You earn your place in it over time through a distinct, well-referenced web footprint.
• Live retrieval (the SearchGPT layer). When browsing kicks in, ChatGPT fetches current pages, reads them, and cites a handful as sources. This is the layer you can influence quickly - but only if your site is reachable, readable, and structured so a passage can be lifted cleanly into an answer.

A brand can win on one layer and lose on the other. You might be recalled from memory but never cited live because your current pages are unreadable; or invisible in memory but pulled in live because your content answers the exact question. SearchScore reports where you stand on each, because the fixes are different.

This is the single most surprising result businesses get, and it's not a fluke - it's structural. ChatGPT's live search does not run on Google's index. It runs largely on Bing's. So the authority you've banked in Google - backlinks Google trusts, rankings you've fought for - does not automatically carry over. If Bing has indexed you thinly, or not at all, ChatGPT's live layer has little to retrieve, no matter how well Google ranks you.

On top of that, the trained-memory layer doesn't care about your current Google position at all. It reflects how often and how clearly your brand appeared across the wider web up to the model's cutoff - publications, directories, forums, structured entity data - not this quarter's SERP. Two independent reasons, then, why a page-one Google site shows up as a blank in ChatGPT. A ChatGPT-specific checker exists precisely because a Google-shaped audit will tell you everything is fine while ChatGPT stays silent.

Most "AI bot" advice treats ChatGPT as a single crawler. It isn't. OpenAI operates three separate agents, each doing a different job, and they fail in different ways:

• GPTBot - gathers content that may inform future training. Block it and you protect your data from the model, but you also forfeit any chance of entering the trained-memory layer down the line.
• OAI-SearchBot - the crawler behind ChatGPT's search results. Block it and you can be erased from the live SearchGPT layer entirely, even if your content is excellent.
• ChatGPT-User - fires when a specific user's request makes ChatGPT fetch a page on demand. Block it and the model can't open your link mid-conversation to verify or quote you.

A blanket Disallow or a well-intentioned "block AI scrapers" rule often catches all three at once - silencing you across every ChatGPT surface while your team assumes the site is wide open. SearchScore checks each agent's access separately and tells you which ones can actually reach you.

You get a single score and a ranked fix list, so you know which change moves ChatGPT visibility first. The same audit also covers Perplexity, Claude, Gemini and Google AI Overviews - but this page is built around what's true for ChatGPT.

For ongoing monitoring, SearchScore's Tracker goes one step further: it puts real prompts to six live engines - ChatGPT, Gemini, Claude, Perplexity, Grok and DeepSeek - and counts exactly how often each one cites you, with a dedicated ChatGPT column. We don't guess whether ChatGPT names you; we ask it and count.

A low score is rarely about content quality - it's usually a plumbing problem you can't see from the front end. The report separates the two failure modes so you don't waste effort:

• "ChatGPT can't reach or read you." An access or rendering issue - a crawler is blocked, or your content only exists after JavaScript runs. High impact, often a fast fix, and it caps everything else.
• "ChatGPT can reach you but has no reason to pick you." A signal issue - weak entity data, no citable passages, or a thin third-party footprint. Slower to move, but it's what decides whether you're named versus merely readable.

Run it on your own domain, then run it on the competitor ChatGPT keeps recommending instead of you - the gap between the two scores is usually the clearest brief you'll ever get for what to fix. Enter your URL to see where you stand, free.

Proof this pattern holds in the wild: across 1,038 UK accountancy firms SearchScore audited, 97% let AI crawl them yet only 18 (1 in 60) covered all five AI-readiness basics. Among 150+ London firms, the average GEO score was just 52.8/100 and only 4 reached the Strong tier. Being reachable is not the same as being recommended.
