Our free SEO Checker analyzes any web page across 200+ ranking factors organized into 6 categories. Enter a URL and get an instant, comprehensive report with actionable recommendations — no registration required.
Evaluates your title tag length (optimal: 30–60 characters), meta description (70–160 characters), canonical URL, robots directives, language declaration, Open Graph tags, Twitter Cards, JSON-LD structured data, charset encoding, doctype, and favicon presence.
Measures word count, text-to-HTML ratio, image ALT text coverage, frameset detection, mobile viewport, strong/bold tag usage, social media tags, and HTTPS mixed content detection.
Validates H1 heading presence and count, heading hierarchy (H1→H2→H3 without skipped levels), internal link count, external link balance, dynamic URL parameters, and duplicate anchor texts.
Checks HTTP status codes, www/non-www consistency, HTTPS usage, response time (target: under 0.40s), content compression (gzip/brotli), and security headers (HSTS).
Verifies XML sitemap presence, robots.txt configuration, outbound link quality, page file size (target: under 200KB), CSS/JS file counts, inline style blocks, and favicon linking.
Your on-page SEO score is calculated as a weighted average across all 6 categories. Each check is scored as pass, partial, or fail. Scores above 80% indicate strong on-page optimization. Scores between 50–79% show room for improvement. Below 50% means critical issues need immediate attention.
The AI Visibility Score runs alongside the SEO score, measuring how well your page is optimized for AI crawlers like GPTBot, ClaudeBot, and PerplexityBot across 5 categories: Crawler Access, Content Extractability, Trust Signals, Structured Data, and Machine-Readable Feeds.
On-page SEO is the foundation of search engine optimization. While backlinks and domain authority matter, search engines primarily evaluate your page content, structure, and technical setup to determine relevance. A well-optimized page with proper meta tags, heading hierarchy, fast load times, and quality content gives you the best chance of ranking for your target keywords.
With the rise of AI-powered search (Google AI Overviews, ChatGPT, Perplexity), optimizing for AI crawlers is equally important. Our dual-score system helps you address both traditional SEO and AI visibility in a single analysis.
An SEO score above 80% is considered strong. Most well-optimized pages score between 70–90%. Focus on fixing errors first (red items), then warnings (yellow items), as errors have the biggest impact on rankings.
Run an SEO check after making significant content or technical changes. For active websites, monthly checks are recommended. After fixing issues, re-run the checker to verify your improvements.
The SEO Score measures traditional on-page factors (meta tags, content, headings, technical setup) that search engines like Google evaluate. The AI Visibility Score measures how accessible and understandable your content is to AI crawlers like GPTBot and ClaudeBot. Both are important for modern search visibility.
