If you've ever run a website through an SEO tool, you've probably seen a number — usually out of 100 — called your SEO score. But what does this number actually mean, and should you care about it?
What Is an SEO Score?
An SEO score is a composite rating that evaluates how well your website follows search engine optimization best practices. It checks factors like meta tags, page speed, mobile-friendliness, content structure, technical health, and more. Think of it as a health checkup for your website.
Most SEO tools — including GetSEOAnalyzer — rate sites on a 0-100 scale. The higher your score, the better optimized your site is for Google and other search engines.
How Is It Calculated?
Different tools use different methodologies, but most check these core categories:
Technical SEO — Is your site fast? Does it have proper SSL, sitemap.xml, robots.txt? Are there broken links or redirect chains?
On-Page SEO — Are your title tags, meta descriptions, H1-H6 headings, and image alt texts properly optimized?
Content Quality — Is the content long enough? Does it use relevant keywords? Is there duplicate content?
Mobile & UX — Is the site responsive? Are tap targets large enough? Does it pass Core Web Vitals?
Authority — Does the site have quality backlinks? Social signals? Brand mentions?
What's a Good SEO Score?
90-100: Excellent. Your site follows SEO best practices almost perfectly.
70-89: Good. There are some issues, but your foundation is solid.
50-69: Needs work. You're leaving rankings on the table.
Below 50: Critical. Your site likely has major issues preventing it from ranking.

SEO Score vs. Google Ranking
An SEO score is not a Google ranking factor. Google doesn't see your SEO tool score. However, the factors that make up your score — page speed, mobile-friendliness, content quality — absolutely are ranking factors. A high SEO score means you've addressed most of these signals.
