Here is what a checker can tell you about your site, what it cannot, and how to read the result you get back.
Response codes, redirects, canonical tags, robots rules and the sitemap. A page that cannot be fetched cannot rank, and this is where most sites lose ground quietly.
Titles, descriptions, heading order, image alt text, structured data and internal links, read as a machine reads them rather than as they look.
Core Web Vitals and the measured load behavior, not a guess from the page weight.
Whether ChatGPT, Perplexity and Claude are allowed to crawl, whether your content survives without JavaScript, and whether your business facts sit where an assistant can lift them.
Security headers, mixed content, certificate state and the page capture, so you see the site the way it is served rather than the way it is cached in your browser.
A checker reads your site. Rankings come from watching a search engine over time, which is rank tracking, and on our side that runs daily on Google during the 7 day trial and from the Starter plan up.
It reports what is measurably wrong. Whether fixing it moves you depends on your market, and anyone promising otherwise is selling.
That needs its own comparison, not a scan of one site.
A score on its own is not a finding. Ask what was measured to produce it.
Our report shows the value behind each check: the response header we read, the number of seconds we recorded, the tag we found or did not find. That is the difference between a result you can act on and a result you have to trust.
Check ours the same way. If a finding does not name what it measured, ignore it.
One website, every check, free, no card. The full check set, not a teaser of it.
