Free Instant SEO Analysis

Analyze a live website or paste full HTML source for a manual audit. This upgraded browser-based version checks titles, descriptions, headings, schema, canonicals, image alt text, keyword usage, readability, links, hreflang, page size, resource counts, recommendations, and now a mini multi-page crawl.

Keyword Analysis (Optional)

Leave blank if you want the tool to audit the page without target keywords.

🔥 Mini Site Audit

Crawl a small set of internal pages from the starting URL and compare scores. Best for a quick browser-based snapshot, not a full enterprise crawl.

Site blocked or CORS issue?
Visit the page in your browser, open page source, copy the full HTML, paste it below, and run the audit manually.

Before / After Comparison

Run an audit, then click “Save Snapshot.” Make changes and run again to compare scores and key improvements.

What This Free SEO Analyzer Checks

This browser-based SEO analyzer reviews important on-page signals that affect search visibility, click-through rate, accessibility, and share previews. It checks title tags, meta descriptions, heading structure, structured data, canonical tags, robots directives, hreflang, image alt text, Open Graph tags, X card tags, HTTPS usage, URL readability, keyword usage, readability, internal and external links, page size, render-blocking hints, and small-crawl comparison data.

Why Use This SEO Audit Tool

Instead of checking page source by hand, you can run one fast audit and see the most important SEO signals in a clean report. This helps site owners, developers, bloggers, and small businesses find missing metadata, weak structure, thin content, incomplete social tags, weak link structure, and keyword targeting gaps before publishing. Because the tool also supports manual HTML paste, it is useful even when a live site blocks direct fetching.
