Whether you manage a personal blog, business website, or multiple client websites, this step-by-step guide will help you understand the process.
What Is Website Spam Score?
Website Spam Score is a third-party SEO metric developed by Moz to estimate how closely a website resembles websites that have previously been penalized or banned by Google.
Moz uses 27 different features to calculate its Spam Score. These indicators help website owners investigate potentially risky characteristics in their backlink profiles.
Moz divides Spam Score into three categories:
- Low Spam Score: 1%–30%
- Medium Spam Score: 31%–60%
- High Spam Score: 61%–100%
However, a high Spam Score does not automatically mean Google has penalized your website.
It is important to understand that Moz Spam Score is not an official Google ranking factor. It should be treated as an investigation metric rather than proof of a Google penalty.
How to Check Website Spam Score
Before learning how to reduce spam score of website, you should first understand your current backlink profile.
Several professional SEO tools can help you investigate suspicious links and evaluate referring domains.
1. Check Moz Spam Score Checker
Moz Link Explorer allows users to investigate backlink information and Spam Score.

Visit:
Follow these steps:
- Open Moz Link Explorer.
- Enter your website domain.
- Run the available analysis.
- Review your Spam Score.
- Check inbound links and referring domains.
- Investigate suspicious websites linking to your domain.
Look for unusual backlink patterns, irrelevant referring domains, and other indicators that may require further investigation.

2. Analyze Backlinks Using Ahrefs
Ahrefs is another professional SEO tool that helps website owners understand their backlink profiles.

Visit:
https://ahrefs.com/site-explorer
Enter your website URL and review the following reports:
- Backlinks
- Referring Domains
- Domain Rating (DR)
- Anchor Text
- New and Lost Backlinks
- Organic Traffic
Does Ahrefs have a Spam Score?
Ahrefs does not provide the same numerical Spam Score metric as Moz. Instead, it provides backlink analysis and other SEO metrics that help users investigate link quality.
A low Domain Rating does not automatically mean a referring domain is spammy.

3. Use Semrush Backlink Audit
Semrush provides a Backlink Audit tool that evaluates potentially toxic backlinks using its own Toxicity Score and indicators.

Visit:
After setting up your project, open Backlink Audit and review the available backlink information.
Pay attention to:
- Potentially toxic backlinks
- Suspicious referring domains
- Unnatural anchor text
- Unusual linking patterns
- Backlink toxicity indicators
Remember that third-party toxicity scores are not equivalent to Google’s assessment of a backlink.
How to Reduce Spam Score of Website
After checking your website, the next step is to investigate the backlinks that may require attention.
Here are practical steps to follow.
1. Identify Suspicious Backlinks
Collect backlink information from Moz, Ahrefs, and Semrush.
Compare the reports and investigate links that show suspicious patterns.
Examples include:
- Links from hacked websites.
- Automatically generated backlinks.
- Paid links intended to manipulate search rankings.
- Unnatural exact-match anchor text patterns.
- Links from irrelevant websites with suspicious content.
- Large numbers of artificial links from unrelated domains.
Do not automatically classify every low-authority website as harmful.
Review the actual website, its content, relevance, and linking behavior before taking action.
2. Request Removal of Unwanted Backlinks
If you identify links that violate Google’s link spam policies, contact the website owners and request removal.
Keep a record of your requests and responses.
If the links cannot be removed, you may need to investigate whether Google’s Disavow Tool is appropriate.
3. Prepare a Google Disavow TXT File
A disavow file tells Google which backlinks you want it to ignore when evaluating your website.
However, Google recommends using this tool only in specific circumstances, such as when your website has a considerable number of spammy or artificial links that have caused or are likely to cause a manual action.
Your final file must be saved as a plain-text .txt document.
Example of a domain disavow file:
# Disavow suspicious domains
domain:example-spam.com
domain:unwantedlinks.com
domain:badbacklinks.net
Example of an individual URL:
https://example.com/spammy-backlink-page.html
Follow these file requirements:
- One domain or URL per line.
- Use
domain:to disavow an entire domain. - Save the file in UTF-8 or 7-bit ASCII encoding.
- Use the
.txtfile extension. - Maximum file size: 2 MB.
- Maximum number of lines: 100,000.
Never upload an unreviewed list of every low-DR or high-Spam-Score domain.
How to Upload a Disavow File to Google Search Console
Once your final TXT file is prepared and reviewed, you can upload it through Google’s official Disavow Links Tool.
Step 1: Visit the Official Google Disavow Tool
Open the following official link:
https://search.google.com/search-console/disavow-links
Sign in with the Google account that has access to your website’s Search Console property.

Step 2: Select Your Website Property
Select the correct website property from the available list.
Make sure you select the website for which you prepared the backlink report.
The Disavow Tool requires an eligible URL-prefix property rather than a Domain property.
Step 3: Upload Your TXT File
After selecting your property:
- Click the upload option.
- Select your final disavow
.txtfile. - Confirm the upload.
- Review any errors displayed by Google.
If Google identifies formatting problems, correct your file before uploading again.
Step 4: Confirm Your Disavow File
After uploading, check the confirmation message and review the uploaded list.
Keep a backup of your TXT file.
Important: Uploading a new disavow list replaces the previously uploaded list for that property. Your replacement file should therefore include all the domains and URLs you still want to disavow.
Google may take several weeks to incorporate the list as it recrawls and reprocesses the affected pages.
How to Get a Professional Spam Score and Backlink Audit
Preparing a disavow file requires more than exporting backlinks from an SEO tool.
You need to compare backlink reports, investigate suspicious referring domains, review link patterns, and carefully decide which domains may require disavowing.
