About FunSEO
FunSEO is a free, instant SEO health check tool designed for website owners, developers, and digital marketers. Enter any URL and get a comprehensive SEO audit in seconds β no account required, no data stored.
What We Do
FunSEO performs a passive scan of any public webpage, analyzing it across nine key SEO dimensions. Each category is scored from 0 to 100, and a weighted overall score gives you a quick snapshot of your site's SEO health. All checks are read-only β we only access publicly available information, just like a search engine crawler would.
For WordPress sites, FunSEO also performs additional security-focused checks specific to the platform, helping you identify common misconfigurations that could expose your site to risk.
What We Check
Meta Tags
Title length, meta description, charset, viewport β the fundamentals search engines read first.
Heading Structure
H1 presence, heading hierarchy, keyword overlap β ensuring your content is logically structured.
Technical SEO
HTTPS, canonical tags, robots.txt, sitemap.xml, noindex detection, and redirect checks.
Performance
Powered by Google PageSpeed Insights: LCP, CLS, TBT, FCP, and overall performance score.
Images
Alt text coverage, lazy loading, and missing dimension attributes that affect page layout.
Social & Schema
Open Graph tags, Twitter Card metadata, and JSON-LD structured data detection.
WordPress Security
For WP sites: plugin/theme exposure, xmlrpc.php, login page protection, version leaks, and more.
Links
Internal and external link counts, nofollow usage, and a sample check for broken links.
