FAQ
Are these tools really free?
Yes — no login, no upsell, no paid tier. Long-term sustainability is funded by the operator's unrelated work; there is no advertising on this site.
Do you store my URLs?
No. The site audit fetches your URL once on the server, returns the body, and forgets the request. We do not log URLs to disk and we do not share them.
Why a server-side fetch instead of pure-browser?
Browsers can't cross-origin fetch arbitrary URLs (CORS). The only way to audit a third-party site without a browser extension is a proxy. We minimize the data we touch: we don't keep the URL or the response.
What's llms.txt?
An emerging convention by Jeremy Howard (Answer.AI) — a Markdown file at the root of your site that tells LLMs which pages to read and in what order. See llmstxt.org for the spec. Anthropic, Perplexity and several IDE assistants already use it where present.
Should I block AI crawlers (GPTBot, ClaudeBot) in robots.txt?
That depends on what you want. Blocking them prevents your content from being used as training data — but also prevents you from being cited in AI overviews. Most content creators who want traffic from AI allow these crawlers. We expose the trade-off in our upcoming robots.txt builder rather than picking for you.
Is PageRank really dead?
Public PageRank scores went away in 2016. The underlying algorithm still informs Google's ranking, but it's one of many hundreds of signals. The 2010s mental model — collect backlinks, rank higher — is too simplistic. Quality of links, topical authority, E-E-A-T, Core Web Vitals, and structured-data quality all matter more now.
