SEO Score API โ€” Instant SEO Audits via API

One API call. 54 checks. A scored SEO report in seconds.

SEO Score API gives developers a dead-simple way to add SEO auditing to any application. Pass a URL, get back a full JSON report with a 0โ€“100 score, letter grade, and prioritized fixes. No SDK required โ€” just an HTTP request from Python, JavaScript, cURL, or any language.

What It Does

Every audit runs 54 checks across seven categories:

  • Meta & Content โ€” Title, description, headings, word count, readability, image alt text, and link analysis
  • Technical SEO โ€” HTTPS, SSL, response time, canonical tags, robots.txt, sitemap.xml, and structured data
  • Social & Open Graph โ€” OG tags, Twitter Cards, and favicons
  • Performance โ€” HTML size, DOM complexity, compression, and render-blocking resources
  • Accessibility โ€” Lang attribute, image alt coverage, and ARIA landmarks
  • AI Readability โ€” Can GPTBot and Claude actually parse your page? Scores crawl access, structure, and extractability for the LLM era
  • Priority Fixes โ€” Ranked, actionable recommendations so you know what to fix first

Most audits complete in under two seconds. Works on JavaScript-rendered sites and Cloudflare-protected pages.

Who It's For

  • SaaS builders adding SEO scoring to dashboards or onboarding flows
  • Agencies automating audits across client portfolios
  • Indie makers monitoring their own sites without expensive tools
  • AI/SEO tool developers who need structured audit data as a building block

Pricing

Free tier includes 2 audits/day with all 54 checks โ€” no credit card required. Paid plans start at $5/month for 200 audits and scale up to 25,000 audits/month at $99/month. All plans include batch audits and score monitoring.

Possible disadvantages of SEO Score API

  • Limited Advanced Features
    Compared to full-featured SEO platforms like Ahrefs, SEMrush, or Moz, SEO Score API may lack advanced features such as backlink analysis, keyword research, competitor tracking, and historical data trends.
  • Rate Limits and Usage Caps
    The API may impose rate limits or request caps, especially on free or lower-tier plans, which can be restrictive for users who need to perform high-volume SEO audits or continuous monitoring.
  • Limited Documentation and Community Support
    As a smaller or niche API service, documentation may not be as thorough as larger platforms, and community support or third-party resources may be limited, making troubleshooting more challenging.
  • Accuracy and Depth Concerns
    The SEO scoring algorithm may not be as refined or comprehensive as industry-leading tools, potentially leading to oversimplified scores that don't fully capture the nuances of a site's SEO performance.
  • Dependency on Third-Party Service
    Relying on an external API for SEO scoring introduces a dependency risk โ€” if the service experiences downtime, changes its pricing, or discontinues, it could disrupt workflows and applications built around it.
