What is an SEO checker?
An SEO checker is a tool that analyses a web page against search engine ranking best practices. It flags missing or broken elements — title tags, meta descriptions, headings, alt text, sitemaps — that stop pages ranking as high as they could in Google.
Why check your SEO regularly?
Sites break silently. A deploy drops a meta tag, a plugin adds noindex, a redirect chain creeps in — and traffic quietly falls for weeks before anyone notices. A 10-second check catches those leaks before they cost real money.
What makes a good SEO score?
Above 88 (grade A) means fundamentals are solid. 60–87 means real opportunities are being missed. Below 60, critical issues are actively suppressing your rankings — fix the red items first, they carry the most weight.
