What is an SEO score

What Is an SEO Score?

An SEO score is a measure of how well the technical aspects and user-facing elements of your website contribute to search engine optimization. SEO scoring is ranked on a scale of 100 and the SEO rating is based on factors that affect crawlability and ranking performance.

A high SEO score means that your website meets the quality standards for good search engine optimization while a low SEO score indicates technical and user experience issues.

Although Google’s algorithm doesn’t take your SEO score into consideration when indexing and ranking your website, a good SEO score is intrinsically linked to higher rankings and search engine visibility.

But how does SEO work to increase your score rating exactly?

Optimizing for the four areas of SEO scoring (technical SEO, content, user experience, and mobile usability) will often benefit your rankings in the search engine results pages (SERP) and are a core component of the process for how to do SEO analysis of a website.

What Is a Good SEO Score?

A good SEO score is between 80 – 100. SEO scores in this range indicate that your website is meeting the top quality standards for search engine optimization in the areas of technical SEO, content, user experience, and mobile usability.

SEO Scoring Factors

Your website’s final SEO score is determined by its performance in these four categories:

Technical SEO

Weighting Priority: High

Technical SEO is an important part of SEO scoring because it affects how well your site can be accessed, crawled, and indexed by search engine web crawlers like Googlebot.

If a site has severe technical issues, then it will not rank high on the SERPs no matter how good you make the content, user experience, or mobile usability.

Technical SEO problems can be a major roadblock to increasing organic traffic from Google, Yahoo, or Bing and often go unnoticed until you use an SEO rating checker or a technical SEO audit tool to measure the performance of the site.

It’s good to make these types of checks and analyses part of your routine website maintenance process so you can increase your SEO score in the following areas:

  • Search engine friendly URLs
  • Website architecture
  • Page speed
  • Server response
  • Indexability
  • Broken links


Weighting Priority: Medium

The quality of your website’s content is another important factor in your overall SEO score.

Search engine algorithms consider how well your content uses on-page SEO optimization, the structure of the page, how pages are linked together, and if it’s meeting the needs of your visitors through the measurement of various on-site metrics.

Websites with good SEO, relevant information, and visitor engagement are typically ranked higher by Google in the search engine results pages for their target keywords.

The following areas make up the SEO score for website content:

  • Meta titles and descriptions for every web page
  • The number of internal links and broken links
  • The presence of duplicate content throughout the site
  • On-page SEO factors like optimized heading tags, keywords in content, and image optimization
  • User metrics like bounce rate, time on page, and average pages per session

User Experience

Weighting Priority: Low

Although this is a low priority for SEO scoring, search engines like Google still take user experience into consideration when ranking website content.

So it’s good to know what your SEO rating is for user experience and look for ways to improve this part of your SEO strategy.

The following factors are what make up the SEO score for user experience:

  • Images are retrievable and load quickly
  • Navigation doesn’t include too many links and has a click-depth of 3 clicks or less to get to any one page on the site

Mobile Usability

Weighting Priority: Medium

Google now uses mobile-first indexing for website content. That means your website must have mobile-friendly content or it will not rank as high for its target queries.

Mobile SEO checks measure how fast your website renders across a range of devices and the following aspects affect your SEO score:

  • Responsiveness of the design
  • Touchscreen compatibility for tapping and scrolling 
  • Page speeds load quickly for the user
