Readback is an AI visibility audit. Enter your website and it visits the page the way ChatGPT, Claude, Perplexity and Google do, then writes up what it finds twice: a plain-language brief for marketing and a technical audit for your web team.
The same 56 checks, written for two different readers. Switch between them at any time, or send each to the person who owns it.
For heads of marketing, brand and content
For heads of product and engineering
Both reports draw on the same nine pillars. Each pillar’s weight follows published research on what AI systems cite, and the crawler documentation from OpenAI, Anthropic, Perplexity, Google and Microsoft. Being reachable carries 26% of the score. llms.txt carries under 1%, because nobody has yet shown that it changes anything.
Can AI crawlers and live fetchers reach the page?
URL accessibility scores 9.5 and preview controls 9.2 out of 10 in the Zyppy review of 54 studies. Nothing else matters if this fails.
Can a model lift a clear, self-contained answer?
Query-answer match 9.2, answer near the top 8.8, AI-ready structure 8.6, self-contained passages 8.0.
Is the content in the HTML that crawlers receive?
Content visibility 7.6. OpenAI, Anthropic, Perplexity and Meta crawlers do not run JavaScript.
Are there concrete facts and sources worth citing?
Factually specific 8.3, explicit phrasing 8.1, cites sources 8.0.
Is it unambiguous who is behind the site?
Brand and entity trust 6.8, entity consistency 5.8. Brand mentions are the strongest correlate in Ahrefs data.
Does the page show when it was updated and by whom?
Freshness 7.0. AI-cited pages are about 26% fresher than organic results in Ahrefs data.
Is the page described in machine-readable form?
Structured data 5.6: a small but consistent positive relationship.
Are URLs, redirects and status codes clean?
Supports crawling and indexing, which the top-ranked factors depend on.
llms.txt, Markdown responses, content signals.
llms.txt scores 2.0, the lowest of 23 factors. Google says no AI-specific files are needed. Weighted accordingly.
Stored in this browser only. Run an audit again to see how the score has moved.
The score estimates how ready a page is to be found, read and quoted by AI systems. It is built from what your server returns, so the same page gets the same score every time.
Whether assistants cite you also depends on how you rank for the searches they run and how often other sites mention your brand. Those are the strongest factors in the research, and neither is visible from your own pages.
Agent requests are sent from this tool, not from the AI companies’ networks. A firewall that verifies crawler IP addresses can treat the two differently, so confirm blocks in your server logs.
For real citation counts use the AI Performance report in Bing Webmaster Tools and the Performance report in Google Search Console, and spot-check answers in the assistants themselves.
