SEO Audit
Audit any URL for SEO issues and get a score
The URL is fetched server-side (like a search engine crawler). No data is stored. Results are computed in your browser.
使用方法
Enter any URL and click Audit. The tool fetches the page server-side and runs six checks: meta tags (title, description, canonical, viewport, language), structured data (JSON-LD validation and rich result eligibility), accessibility (headings, alt text, form labels, landmarks, zoom), social preview (Open Graph, Twitter Card), robots.txt (syntax, sitemap reference, AI bot rules), and technical SEO (HTTPS, status codes, noindex directives, HTML size). Each section gets a score, and the overall score is a weighted average. Click any section tab to see individual checks with pass/warn/fail status and specific recommendations.
示例
Check your homepage
Enter your site homepage URL to get a comprehensive SEO health check. The audit catches common issues like missing meta descriptions, absent OG images, and heading hierarchy problems that hurt search rankings.
Audit a landing page before launch
Before publishing a new page, run an audit to catch issues early. Check that structured data is valid, social previews look correct, and no accidental noindex tags block indexing.
Compare competitor pages
Audit competitor URLs to see what structured data they use, how their meta tags are configured, and whether they block AI crawlers. Use these insights to improve your own pages.
Frequently asked questions
What does the SEO audit check?
The audit runs six checks: meta tags (title length, description, canonical URL, viewport, language attribute), structured data (JSON-LD syntax, schema.org types, rich result eligibility), accessibility (heading hierarchy, image alt text, form labels, landmarks, zoom support), social preview (Open Graph tags, Twitter Card), robots.txt (syntax validation, sitemap reference, AI bot rules), and technical SEO (HTTP status, HTTPS usage, noindex directives, HTML size).
How is the overall score calculated?
Each of the six sections receives a score from 0 to 100 based on how many checks pass (warnings count as half credit). The overall score is a weighted average: meta tags (25%), accessibility (20%), structured data (15%), social preview (15%), technical (15%), and robots.txt (10%). A score above 90 is excellent, 70-89 is good, 50-69 needs work, and below 50 is poor.
Does the audit check page speed or Core Web Vitals?
No. This audit focuses on on-page SEO elements that are visible in the HTML source: meta tags, structured data, accessibility, and technical configuration. For performance metrics like LCP, FID, and CLS, use Google PageSpeed Insights or Lighthouse.
Can I audit pages behind a login?
No. The tool fetches the URL server-side like a search engine crawler would. Pages that require authentication will return the login page HTML instead of the actual content. Audit public-facing pages only.
How often should I audit my pages?
Audit after every major content or template change. For ongoing monitoring, check your most important pages (homepage, key landing pages, top blog posts) monthly. Run an audit before launching any new page to catch issues before search engines index it.
