Spam Score


Spam Score in the SEO space is a metric developed by Moz that predicts the likelihood of a website being penalized or banned by search engines. It assesses various factors that are typically associated with spammy websites, assigning a score ranging from 0 to 17. The higher the score, the greater the likelihood that the site exhibits characteristics of spam. This score is essential for SEO professionals as it helps identify potential risks associated with link-building strategies and overall website health. By monitoring and managing Spam Score, businesses can maintain their website’s credibility and avoid penalties from search engines.

Spam Score is calculated by analyzing multiple spam flags, such as low-quality content, excessive keyword stuffing, suspicious link patterns, and other indicators. These factors are then combined to produce an overall score. Websites with a high Spam Score might need to review and clean up their content and backlink profile to reduce the risk of being flagged by search engines.

How You Can Use Spam Score


Consider that you are managing an SEO campaign for an online retailer. One of your strategies is to build backlinks from various websites to improve your site’s authority and search rankings. Before pursuing these backlinks, you should check the Spam Scores of the potential linking sites. Suppose you find that several sites you were considering have high Spam Scores. This information indicates that these sites could harm your SEO efforts rather than help them.

In this scenario, you decide to avoid high-risk sites and focus on acquiring backlinks from reputable sources with low Spam Scores. By doing so, you ensure that your link-building strategy strengthens your website’s authority without exposing it to the risk of penalties. Additionally, you can use the Spam Score to audit your current backlinks, identifying and disavowing those that come from spammy sites to protect your SEO health.

Spam Score Calculation

Spam Score is calculated based on a set of predefined spam flags that Moz has identified through extensive research. Each flag represents a specific factor commonly found in spammy websites. These flags include issues such as:

  1. Low MozTrust or MozRank scores.
  2. A large number of external links compared to internal links.
  3. A high ratio of follow-to-nofollow links.
  4. Overuse of anchor text keywords.
  5. Thin or duplicate content.

Each of these flags contributes to the overall Spam Score, which is the total number of flags triggered. For example, if a website triggers 7 out of the 17 possible spam flags, its Spam Score would be 7. The higher the number of flags, the more likely the website is considered spammy.

Key Takeaways

  1. Spam Score helps identify potential risks associated with websites.
  2. It is crucial for managing and optimizing backlink strategies.
  3. A high Spam Score indicates a greater likelihood of being penalized by search engines.
  4. Regular monitoring can help maintain website credibility and SEO health.
  5. Addressing spam flags can reduce the Spam Score and improve site quality.
