Site Audit

No. It audits the one URL you enter in depth, plus the site-wide files around it (robots.txt, sitemap, the http and www versions and a soft 404 test) and a sample of up to 25 links on the page.

Each check has a weight by severity (critical, warning, notice). A pass earns the full weight, a warning half, a failure none. Area scores roll up into the overall score, with crawling and indexing weighted highest. When Lighthouse runs, the mobile performance score counts for half of the performance area.

It reads the checks this audit already ran and writes a short summary, a "fix these first" list and better title and description suggestions. Every fix it lists points at a real check, so it cannot invent problems. Without AI, the list is ordered by severity instead.

Yes. Share gives you a link to the full report as it was when you ran it. Anyone with the link can open it for 90 days without an account, and search engines are told not to index it.

Whether ChatGPT, Claude, Perplexity and Google's AI features can read and quote the page. Their crawlers do not run JavaScript, so we check the text in the HTML the server sends, plus questions with answers, dates, who is behind the page, contact details, specific facts and sources, llms.txt and whether robots.txt lets AI crawlers in.

Speed figures from real Chrome users over the last 28 days. Google publishes them for sites with enough traffic and uses them in ranking. Lighthouse is a lab test of a single page load, so when the two disagree, go by the real-visitor numbers.

Some sites refuse automated requests (HTTP 401, 403 or 429) or answer too slowly, and social networks often send bots an error for pages that open fine in a browser (LinkedIn answers 999, Facebook 400). Those links are not counted as broken, because the check cannot prove they are.

Most checks finish in 5 to 15 seconds. Lighthouse speed scores come from Google running a real desktop and mobile test, which takes 20 to 40 seconds on most pages and up to about 80 on heavy ones. If Google fails once, we retry automatically.

Lighthouse measures a real page load, so network and server timing shift the result a little each run. Differences of 5 to 15 points on the performance score are normal. Look at the trend, not a single number.

It follows your internal links from the homepage, up to 25 pages for visitors and 60 when signed in, and reports what a single page cannot show: pages nothing links to, broken internal links, pages buried too deep and duplicate titles. It runs at the same time as the speed tests, so the audit does not take longer. For the full picture, including the site tree and AI link suggestions, use the Site Crawl tool.

Yes, 5 audits per minute per visitor, because each audit makes around 40 requests.

Anything that stops pages being crawled or indexed: broken internal links, redirect chains and pages nothing links to. The site crawl tool lists those link problems page by page, and our guide to internal linking explains how to fix the structure behind them.
