Website SEO Checker: Run a Complete Technical Site Audit
Analyze any website for SEO issues in seconds. Our SEO audit tool identifies technical SEO problems, broken links, missing meta tags, and optimization opportunities with actionable recommendations.
How Our Website SEO Checker Works
Our Website SEO Checker fetches your page in real-time and analyzes the HTML structure exactly as search engines see it. Unlike basic crawlers, our audit engine parses metadata, heading hierarchies, internal linking patterns, image attributes, and technical signals all in a single scan – making it a complete website audit tool and SEO analyzer in one.
We built this tool to simulate how Googlebot processes your page. The checker validates title tag completeness, identifies meta description truncation risks, flags missing H1 tags, and detects broken internal links that waste crawl budget. When you enable Core Web Vitals, we pull real Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Interaction to Next Paint (INP) metrics from Google's PageSpeed Insights API for a technical website audit that covers both crawlability and user experience.
Every recommendation comes with a specific fix, not just a flag. If your meta description runs long, we show you exactly where to trim. If images lack ALT text, we list the affected files and explain how to write effective descriptions. This site audit checker is designed for site owners who want to act on findings immediately without needing an SEO background.
Audit Methodology
We request the page with a standard user-agent, then parse the full HTML DOM including dynamically injected meta tags visible in the source.
Each element is checked against Google's SEO guidelines, character limits, and accessibility standards. We flag issues by severity.
We calculate a weighted score and generate prioritized fixes. The report shows exactly what to change and why it matters.
