What You Get

Our free SEO score checker analyzes 28 factors across 5 categories and gives you:

• An overall score from 0-100 with a letter grade (A+ to F)
• Category breakdowns so you know which area needs the most attention
• Specific issues with severity ratings (high, medium, low)
• Fix recommendations — not just what's wrong, but exactly how to fix it

What We Check

Is your title tag the right length? Do you have a meta description? Is your H1 tag present and unique? How's your content length and readability? Are your images missing alt text?

Technical SEO (10 checks)

Is your site on HTTPS with a valid SSL cert? How fast is your server response? Do you have a canonical tag, sitemap, and robots.txt? Is there structured data for rich snippets?

Social & Open Graph (3 checks)

When someone shares your link on Twitter or Facebook, does it look good? We check OG tags, Twitter Cards, and favicon.

Performance (4 checks)
