  • Technical SEO — Status codes, canonical tags, robots directives, charset, and doctype. These are the basics that search engines need to crawl and index your site.
  • On-Page SEO — Title tags, meta descriptions, heading hierarchy, image alt text. These help search engines understand what each page is about.
  • Performance — Page load time, compression, resource hints like preconnect and prefetch, async scripts, and font loading. Fast sites rank higher.
  • Security — HTTPS, HSTS, Content Security Policy, X-Frame-Options, and other headers that protect your users and boost trust.
  • Structured Data — JSON-LD schemas such as Organization, BreadcrumbList, FAQ, Article, and Product. Rich data helps you get rich search results.
  • Content Quality — Word count, reading level, and content depth. Pages with clear, useful text rank better than thin or hard-to-read content.
  • Mobile and Access — Viewport tag, language attribute, ARIA roles, semantic HTML elements. A site must work well on all devices and for all users.
  • Link Structure — Internal links, external links, broken links, and click depth. Good linking helps users and search engines navigate your site.
  • Social Tags — Open Graph and Twitter Card meta tags. These control how your pages look when shared on social media platforms.

SEO Scoring Weights

Each category has a weight that shows how much it counts toward your total site score. Technical and on-page SEO matter the most because search engines rely on them to crawl and rank your pages. Here is the full weight table for all nine areas.

SEO Grade Scale

After we score your pages, each one gets a letter grade from A+ to F. The grade makes it easy to tell at a glance how well your site is doing. A score of 90 or above earns you an A grade, while anything below 60 is a failing grade that needs work.

GradeScore RangeMeaning
A+97 – 100Excellent, best in class SEO
A / A-90 – 96Great SEO with minor tweaks needed
B+ / B / B-80 – 89Good but has clear room for gains
C+ / C / C-70 – 79Average, several areas need work
D+ / D / D-60 – 69Below average with major issues
