Why audit your site
Technical SEO is what keeps your content findable.
Even the best content won't rank if Google can't crawl it, can't index it, or has to wait three seconds for it to load. A technical website audit catches the issues nobody sees — until traffic disappears.
What a website audit tool actually checks
A site auditor crawls your pages the way a search engine does: status codes, redirects, meta tags, h1, canonical, hreflang, robots directives, Core Web Vitals, JavaScript errors, sitemap parity, structured data. Every issue gets categorised by severity, paired with the affected URLs, and shipped with a fix recommendation.
When to run an audit
- After a deploy — catch redirect chains, broken canonicals and noindex slips before traffic does.
- Monthly health check — a 7-day crawl baseline is the cheapest insurance against silent SEO regressions.
- When traffic drops — separate algorithm volatility from a real technical issue with one click.
- Before a redesign — get a before/after Health Score so you can prove the redesign didn't hurt rankings.
Why a free preview, not a free plan
Real audits cost crawl bandwidth — a 10,000-page site means 10,000 outbound HTTP requests on our infrastructure. The free preview gives you the Health Score for one URL so you know what the tool can do; the free plan lands 500 tokens in your account and unlocks the full report for any project you create.
