What is Spam Score in SEO and How to Reduce It? - A Comprehensive Guide
If you are learning SEO, you must have seen the term spam score in tools like Moz. Many beginners panic when they see a high spam score and assume their website will be penalized by Google.
But the truth is different. In this blog, you will clearly understand what is spam score in SEO, how it works, what Moz spam score really means, and most importantly, how to reduce spam score of a website safely. This guide is written specially for beginners and Skillwaala students.
What Is Spam Score in SEO?
Spam score is a metric created by Moz to show how risky or spam-like a website’s link profile looks. In simple words, Spam score tells you how many signals on your website match patterns commonly found on spammy sites. It does not mean your website is penalized by Google.
So when people ask what is Moz spam score, the answer is: It is a warning signal, not a punishment.
What Is Moz Spam Score?
Moz Spam Score is shown as a percentage from 0% to 100% and helps identify how risky a website looks based on spam-related signals. A lower spam score means the website appears safe, while a higher score shows possible spam issues. Moz calculates this score by comparing your website with known spam patterns.
Note: Spam score is a Moz metric only and is not used by Google for rankings.
How Spam Score Is Calculated
Moz calculates Spam Score by analyzing multiple signals that are commonly found on low-quality or spammy websites.
Quality of Backlinks
If a website has too many links coming from spam, irrelevant, or low-authority sites, its spam score can increase.
Content Quality
Websites with thin, duplicated, or copied content are more likely to be flagged.
Keyword Overuse
Where keywords are unnaturally stuffed just to manipulate search rankings.
Poor Site Structure
A poor site structure, such as broken links, missing pages, or confusing navigation, can also contribute to a higher spam score.
Moz uses machine learning to compare your website with a large database of known spam sites. This is why your spam score may change over time, even if you haven’t made any updates, because Moz’s comparison data and algorithms keep evolving.
What Is a Good Spam Score?
There is no fixed number, but generally:
0% to 30%: Low risk (safe) and shows a healthy backlink profile
31% to 60%: Medium risk (needs attention and regular monitoring)
Above 60%: High risk (serious cleanup of backlinks required)
A low spam score does not guarantee rankings, but a very high spam score is a clear warning sign that your backlink profile and SEO practices need improvement.
Is Spam Score a Google Ranking Factor?
No, spam score is NOT a Google ranking factor. Google does not use Moz metrics or any third-party scores to decide search rankings. Spam score is created by Moz only for SEO analysis.
However:
Google does take action against spammy behavior, such as paid links, link schemes, and low-quality content.
If a website follows spam SEO practices, Google may reduce its rankings or apply manual actions.
Moz spam score helps you identify risky patterns early, before they cause real SEO damage.
It works as a health check for backlinks and site quality, not a ranking signal.
So, spam score should be treated as a warning system. It helps you fix problems early, but rankings depend on clean SEO, good, and user-focused content.
Common Reasons for High Spam Score
Understanding the cause is the first step in learning how to reduce the spam score.
The most common reasons include:
Backlinks from spam websites
Paid or link-farm backlinks
Low-quality guest posting
Copied or thin content
Keyword stuffing and spam SEO techniques
All these practices listed above fall under SEO spamming that should always be avoided.
How to Check Spam Score (SEO Spam Check)
You can easily perform an SEO spam check using official Moz tools. Since Moz created the spam score metric, its tools give the most accurate results.
Steps to Check Spam Score:
Open Moz Link Explorer in your browser
Enter your website URL or a specific page URL
Click on Analyze
Check the Spam Score percentage shown in the report
Review backlink data to understand risk sources
You can also use the MozBar browser extension to see the spam score directly while browsing any website. This is helpful for quick checks during backlink analysis, competitor research, and link-building planning.
How to Reduce Spam Score of a Website (Practical Steps)
Now the most important part is how to reduce the spam score of a website safely.
Here are the step-by-step actions to take for reducing the spam score of a website. Although these steps won’t give you instant results but will take time.
Remove toxic backlinks by contacting site owners or using disavow tool
Avoid spam SEO practices like keyword stuffing
Get backlinks from trusted websites in your niche
Improve content quality and originality
Fix technical SEO issues like broken pages
Stop buying links or using link schemes
There is no instant fix. Reducing the spam score of a website will take its own sweet time, but it will work.
How Long Does It Take to Reduce Spam Score?
Spam score does not drop overnight, because it depends on backlink changes and Moz index updates.
Small Improvements: 2 to 4 weeks
When you remove a few bad links, fix content issues, or stop spam SEO practices, you may see a slight drop in spam score.
Major Cleanup: 2 to 3 months
If your website has many toxic backlinks, link farms, or long-term spam issues, cleanup takes more time and effort.
Moz updates spam score only after refreshing its backlink database. So even after fixing issues, you may not see the results appear immediately. This is why patience and consistent cleanup are very important when trying to reduce spam score safely.
Best Practices to Prevent High Spam Score
Prevention is always easier than fixing a high spam score later. A clean SEO approach keeps your website safe in the long run.
Follow These Rules:
Build links naturally: Get backlinks from relevant and trusted websites instead of buying or exchanging links.
Publish useful and original content: Content that solves user problems attracts natural links and trust.
Do regular backlink audits: Check your backlinks monthly and remove or disavow harmful links early.
Avoid SEO spamming shortcuts: Keyword stuffing, link farms, and auto-generated content increase spam score.
Focus on long-term SEO growth: Slow and steady SEO always performs better than quick, risky tactics.
Following these practices helps keep your spam score low naturally and protects your website’s SEO health.
Spam Score vs Real SEO Success
When you are into SEO, then remember that spam score alone does not decide rankings.
Real SEO success depends on:
Content usefulness that solves real user problems.
Search intent match with what users are actually looking for.
Good user experience like fast speed and easy navigation.
Trusted backlinks from relevant websites.
Clean SEO practices without shortcuts.
Spam score only helps you identify risks and in no way does it predict rankings or traffic.
Conclusion
Spam score is something to understand, not to fear. Use spam score as a health check tool, not a ranking meter. Avoid shortcuts, follow ethical SEO, and focus on real value for users. If your website helps users and follows clean SEO practices, your spam score will take care of itself.
