Think your emails or website are safe from the spam folder? Think again. Studies show that 21% of legitimate emails never reach the inbox (Validity, 2023)—mostly because of a poor spam score.

A spam score checker can help you identify potential issues, such as email sending limits, that may prevent your emails from reaching the inbox.

In this guide, you’ll learn how to use a spam score checker, which is completely free, alongside simple steps to keep your domain reputation clean and your messages where they belong: in front of people, not in the junk box.

What Is a Spam Score Checker and Why Does It Matter?

A spam score checker is a simple tool that tells you how safe your website or email looks to search engines and email filters. Strong spam filters decide if your emails go to the inbox or junk folder. It checks for bad links, low quality sites, spammy backlinks, and other spam indicators.

Spam checkers evaluate your domain spam score to identify spammy backlinks and assess the overall health of your domain, helping you detect potential penalties and manage your link profile.

Why does it matter?

Domain age can also affect how safe your website looks to search engines.

• A high spam score can block your emails or lower your search engine rankings.

A good spam score tells you that search engines and email tools trust your site or emails. Most experts say a score below 5% is safe.

If your spam score checker shows a high spam score, it means risky links or low quality sites are connected to your domain. Keep checking with tools and remove spammy backlinks to stay safe.

Tip: “Moz reports that sites with a low spam score have a 90% better chance to rank higher, which indicates a higher likelihood of success in search engine results.”

How to Identify Low Quality Links That Hurt Your Spam Score

Spotting low quality links is essential for maintaining a healthy spam score and protecting your website’s reputation with search engines. Here’s how you can use a spam checker or bulk spam score checker to identify and deal with harmful links:

1. Analyze Your Backlink Profile: Start by running your domain through a trusted spam checker or bulk spam score checker. These tools scan your website’s backlink profile for spammy links and highlight potential risks.
2. Look for Links from Low Quality Sites: Pay attention to backlinks from sites with low domain authority or page authority. Links from these sources are often considered spammy by search engines.
3. Watch Out for Link Farms and Thin Content: If your report shows links from link farms or sites with thin content, these are red flags. Such links can quickly increase your spam score.
4. Check Anchor Text Diversity: Excessive use of optimized anchor text (the clickable part of a link) can signal manipulative linking practices. A natural, varied link profile is safer.
5. Identify Hidden or Embedded Links: Some spammy links are hidden in images or embedded in ways that try to trick search engines. Use your spam checker’s detailed report to spot these.
6. Review for Relevance and Diversity: Links should come from a variety of reputable, relevant sites. Too many links from unrelated or low quality domains can hurt your score.
7. Monitor New Links Regularly: Set a schedule to review your backlink profile often. New spammy links can appear at any time, so regular checks are key.
8. Use a Disavow File When Needed: If you find links you can’t remove, use Google’s disavow file tool to tell search engines to ignore them. This helps protect your website’s spam score.

By following these steps and using the right tools, you can keep your backlink profile clean, maintain a good spam score, and improve your site’s trust with search engines.

What to Do If You Have a High Spam Score

1. Run a Detailed Spam Score Checker Scan

Open a trusted spam score checker tool. Add your domain or URLs in the input box. Check spam score for your site and emails. A detailed report will show issues like toxic backlinks and thin content.

2. Remove Toxic and Spammy Backlinks

Look at the backlinks list in the report. Remove toxic backlinks from low quality sites or link farms, as these pose a high risk to your domain's reputation and hinder your efforts in building backlinks . Use link removal requests or a disavow file if you cannot remove them.

Tip: Avoid creating fake domains just for signup purposes as it increases risk.

3. Fix Thin and Low Quality Content Quality

Content writers should focus on quality to avoid thin content warnings. Review all your pages. Rewrite thin or low quality content with simple, helpful information. Add new data, images, and examples.

4. Build High Quality Backlinks from Reputable Sources

Add guest blogging on authoritative sites. Focus on high quality backlinks from trusted websites. These links balance a poor backlink profile and lower spam indicator.

5. Monitor Improvements Over Time

Download excel report after each scan. Compare reports every month. Small changes in the score show progress.

6. Improve Website Signals Beyond Links

Check site speed, mobile design, and user engagement. Clean your website’s backlink profile. A good spam score often comes with better rankings.
