Real-Time Execution Engineπ What This Free Website SEO Audit Checks
Our free technical SEO audit tool inspects your web page in real time to diagnose critical on-page factors. Search engine crawlers evaluate these signals to index and rank your pages. Every check follows official search guidelines and modern technical standards:
β Page Title Optimization
Verifies that a <title> tag exists and falls within the optimal length of 30 to 65 characters to prevent truncation in search engine snippets.
β Meta Description Length
Inspects the <meta name="description"> tag to ensure it contains between 120 and 165 characters for informative search result previews.
β Heading Hierarchy (H1 & H2)
Confirms the page contains exactly one primary <h1> tag for topical clarity, and tallies supporting <h2> subheadings across the page.
β Canonical URL Declaration
Detects the <link rel="canonical"> attribute to ensure the authoritative destination URL is explicitly declared, avoiding duplicate content penalties.
β Robots Indexing Directives
Inspects <meta name="robots"> content to verify that search engine crawlers are permitted to index the URL and follow internal links.
β Open Graph Social Markup
Checks for og:title and og:image tags to verify that social cards and link unfurls render rich visual media when shared online.
β Image Alt Accessibility
Scans all inline <img> elements and flags missing alt attributes to improve accessibility and image search indexing.
β Overall On-Page Health Score
Calculates an algorithmic health score between 20 and 100 based on weighted technical criteria, giving you an instant diagnostic summary.
β Diagnostic Scope Notice
This tool focuses on single-URL on-page technical SEO diagnostics. It does not run multi-page site crawls, backlink audits, or domain authority checks. To evaluate loading speed and visual stability, test real-world Core Web Vitals and TTFB performance. For site configuration, use our complementary XML Sitemap Generator and Robots.txt Generator.
