How accurate is the score?

Every check is based on what Google and the AI providers document publicly, and title widths are measured in pixels the way Google displays them. The score is a guide to how well-prepared a page is – no tool can guarantee rankings, because Google also weighs links, competition and many other signals.

Do you store my website's content?

No. We fetch the page like a search engine would, analyse it and keep only the finished report in a short-lived cache for an hour so repeat views are fast.

Is there a limit on how many sites I can check?

Not for normal use. The instant tools run in your browser and are unlimited. Full checks and audits only have a safety limit set far above what a person can use by hand (two checks a minute, every minute), plus a cap on how often any one website can be checked – that stops bots using XKey to flood other people's sites.

Do I need to give my email address?

No. XKey never asks for an email, an account or card details – not even for weekly monitoring, which gives you a private link instead.

Can I download my SEO report without signing up?

Yes. Use "Print or save as PDF" at the bottom of any report. The website audit also gives you a PDF and a CSV of every page, with no sign-up.

Can I check a competitor's website?

Yes – any public website. To see your site and up to two competitors side by side, use the competitor comparison.

Why is my score different from other SEO checkers?

Each tool weights different checks. XKey gives extra weight to things that stop a page appearing at all (indexing, titles, H1) and adds AI search readiness, which most checkers don't measure yet.
