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 Moz

  • Cost

  • Slow Updates
    Some users have reported that Moz can be slow in updating keyword rankings and other metrics, which can be frustrating for those needing real-time data.
  • Limited Global Databases
    While Moz is strong in certain regions, its databases are less comprehensive in some international markets compared to competitors.
  • Complexity for Beginners
    Despite its user-friendly interface, the depth and breadth of tools can be overwhelming for complete beginners to SEO.
  • Data Accuracy
    While generally reliable, there have been occasional concerns about the accuracy of Moz's backlink data compared to other SEO tools.
  • Pricing
    Moz Pro is relatively expensive compared to some other SEO tools, which might be a barrier for small businesses and individual users.
  • Learning Curve
    While the interface is user-friendly, the depth and breadth of features mean that new users may need time to learn how to use the platform effectively.
  • Limited Data for Lower Tiers
    Some of the lower-priced plans offer limited access to data and features, which may not be sufficient for larger or more competitive websites.
  • Data Limitations
    There may be limitations in terms of data availability and accuracy, particularly in comparison to some competitors who offer broader datasets.
  • Steep Learning Curve for Advanced Features
    While basic features are user-friendly, some of the more advanced functionalities may require a bit of a learning curve for new users.
  • Limited International Focus
    Moz has historically had a stronger focus on the US market, which may limit its applicability for users focusing predominantly on international SEO.
  • Keyword Data Restrictions
    Users sometimes report limitations in keyword data, particularly when compared with other tools that offer more extensive keyword research capabilities.
  • Limited Free Features
    Many of the advanced features of MozBar require a paid subscription, making it less accessible for users who prefer free tools.
  • Requires Moz Account
    Users must create a Moz account to fully utilize the features, which might be inconvenient for those who wish to avoid additional account registrations.
  • Browser Dependency
    MozBar is only available as a browser extension, limiting its use to supported browsers and possibly causing compatibility issues.
  • Performance Impact
    Some users report that having MozBar enabled can slow down their browser's performance, especially when handling data-intensive tasks.
  • Steeper Learning Curve for Beginners
    Although the user interface is friendly, beginners might find the array of SEO metrics overwhelming without prior knowledge or guidance.
  • Limited Free Access
    The free version offers limited functionality and a restricted number of keyword searches, which may not be sufficient for in-depth research.
  • Data Delay
    There can sometimes be a delay in data updates, meaning the information might not always be the most current.
  • Learning Curve for Advanced Features
    While the basic interface is user-friendly, some advanced features and functionalities might require a learning period to use effectively.
  • Geographical Limitations
    The tool may not provide as comprehensive data for certain non-English-speaking countries, making it less effective for international SEO strategies.

SEO Score API features and specs

  • Cost-Effective for Small Projects

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.

Its a simple to use library that integrates with Python, NodeJS and n8n!

What's the story behind your product?

SEO Score API's answer:

SEO Score API started as a project where I let an AI build a project using only a single AWS EC2 instance. I have since taken over and really started putting muscle into the API. It has become an invaluable tool in my toolbox

Why should a person choose your product over its competitors?

Python. That's it.
