If you've ever run an SEO audit, you've probably seen a number between 0 and 100. But what does that number actually mean? And what score should you be aiming for?
An SEO score is a simplified measure of how well a web page follows search engine optimization best practices. It's not a direct ranking factor — Google doesn't use third-party scores. Instead, it's a proxy that tells you how many common issues exist on your page.
Think of it like a health checkup. A score of 95 doesn't guarantee you'll never get sick. But it means the basics are covered.
A good SEO audit covers more than just meta tags. Here are the 5 categories that matter:
Title tag, meta description, heading structure (H1-H6), content length, readability, image alt text, and internal/external links. These are the first things search engines read.
HTTPS, SSL certificate, response time, canonical tags, mobile viewport, robots.txt, sitemap.xml, and structured data (Schema.org). These help search engines crawl and index your site correctly.
OG tags (title, description, image), Twitter Cards, and favicon. These control how your links look when shared on social media.
HTML size, DOM complexity, compression (gzip/brotli), and render-blocking resources. Faster pages rank better and convert more.
Language attribute, alt text coverage, and ARIA landmarks. Accessibility isn't just the right thing to do — it's increasingly an SEO signal.
You can check any website's SEO score right now using our free live demo. Enter a URL, click Audit, and get a full report in seconds.
For developers who want to integrate SEO checking into their apps, our API returns the same data as structured JSON.
Aim for 90+ on your most important pages (homepage, landing pages, key blog posts). Don't obsess over getting to 100 — some deductions are unavoidable (technical content will always score lower on readability, for example).
Focus on fixing the priorities first. A page that goes from 65 to 85 by fixing 3 high-severity issues will see more impact than a page going from 92 to 96 by tweaking minor details.
