SEO Analyzer
Our SEO Analyzer provides a comprehensive audit of any web page. Simply enter a URL and our tool will fetch the content to analyze critical SEO factors including meta titles, descriptions, heading structures (H1-H6), image alt attributes, and social media tags (Open Graph & Twitter). It also checks the canonical link, viewport meta tag, declared language, charset, and counts how many H1s appear, then converts every result into a weighted score out of 100: a missing title or description costs 15 points, heading and canonical problems cost 10 to 15, and smaller gaps like charset or lang attributes cost 5. Each failed check comes with a plain-language fix, so you know what to change first. Get a clear, actionable report on what is working and what needs improvement to boost your search engine rankings.

Questions People Ask
Honest answers about how this works.
How exactly does it fetch the page?
We use a secure server-side proxy that requests the public HTML of the URL you provide and returns it to your browser for analysis. No personal data, cookies, or credentials are transmitted, and the tool only reads what any search engine crawler could fetch publicly from the same address.
Can I really analyze password-protected pages?
Great question. No. The proxy fetches the same public HTML a crawler would receive, so pages behind a login, paywall, or robots restriction cannot be read. Open the page in a private window without cookies first; if it loads there, the SEO Analyzer can audit it too.
How is the SEO score calculated?
The audit starts at 100 and subtracts weighted penalties: 15 for a missing title, description, or H1; 10 for canonical, alt text, social tags, or viewport issues; 5 for language and charset gaps. Everything is graded from the fetched HTML, so a score of 80 tells you roughly which deductions you still carry.
