How to check Spam Score

A website spam score checker helps you screen spam scores before outreach. Paste a list, then read spam scores next to authority and link counts — no signup.

Paste domain names into the form above — one per line, without https:// or paths (e.g. example.com). Up to 10 domains per check.

Click Check Spam Score. The counter on the button shows how many of your 10 free domains for today you have used across all free tools.

Read spam scores in the table — authority, link counts, and referring domains for every name.

Copy the table if you need results in the excel for an audit. This page does not generate an excel report. Follow related tools to also check the same list.

What you get

Batch table — spam scores for ten domains side by side.
Context metrics — authority and link counts from the same Moz lookup, so spam scores are not read in isolation.
Shareable run — save the link and rerun the same names later.

What Moz Spam Score means

Spam score is a metric developed by Moz (1–100%; lower is better). It is a metric that reflects spam-like patterns on a host. This spam score checker tool is built for bulk runs — up to ten domains — so you can screen a shortlist before you treat a site as a safe link source.

How to read spam scores

Moz groups spam scores into three bands: 1–30% is a low spam score (low risk), 31–60% is medium risk / moderate risk, and 61–100% is high risk. A high spam score means sites with similar features were more often penalized or banned by Google — not proof this site was penalized by Google.

Always use spam score next to Domain Authority. A modest number on a strong site is different from the same spam scores on a thin content domain with almost no referring domains. Treat the number as spam risk, not a verdict, and do not confuse a dash with low spam signals.

What the columns show

The table returns four fields from one Moz metrics lookup: authority, spam scores, link counts, and referring root domains. We do not pull a separate link list here.

Empty cells usually mean Moz has little data yet — common for a new domain, low-traffic names, or unlinked hosts. Recheck later rather than treating a dash as a clean bill of health.

Why compare spam scores in bulk?

Use a bulk pass to screen outreach targets, guest-post sites, or a link shortlist before you spend time on a full report. Ten names in one table is faster than reading spam scores one by one.

High spam score domains are a triage flag, not proof that Google has taken action. Investigate the backlink profile, then decide whether to skip the source or consider disavowing toxic links.

How this tool works

Enter the list, click the button, and complete captcha. We look up Moz metrics for each name and return spam scores with authority and link counts in one table — up to ten domains per run, ten domains per day across our free tools.

This page is the Moz spam score checker for SS plus authority and link counts. For DR, KDM, and Semrush, open the authority checker with the same list. For inbound URLs, use the Backlink Checker.

Frequently Asked Questions

What do spam scores measure?

Spam scores estimate how many spam-like flags Moz sees on a host. Our bulk table also shows authority and referring domains for up to 10 domains in one run.

What is a good range?

1–30% is Low. 31–60% is Medium. 61–100% is High. Lower spam scores are safer as a starting point. Do not treat the number as a hard Google penalty threshold.

Is this a Google ranking signal?

No. Spam score is Moz's third-party estimate of spam-like signals. It is not a Google penalty score and not a confirmed ranking factor. Search engines may penalize a site for other reasons. Use it as one input alongside on-page quality and relevant content.

How many names can I check at once?

Paste up to 10 domain names per run. Duplicate entries are removed automatically. Enter bare names (e.g. example.com) without paths or protocols.

Are there usage limits?

Up to 10 domains per run, one check at a time, 10 domains per day across our free landing tools. Regularly check a shortlist rather than one name at a time when you can.

Why is a row empty?

Moz may not have indexed the name yet — typical for a new domain. Empty spam scores are missing data, not a zero. Try again later or open a fuller report in Karma.Domains.

How is this different from the authority checker?

This Moz spam checker focuses on spam scores plus authority and link counts from one lookup. The Domain Authority Checker adds Ahrefs DR/UR, Semrush scores, Open PageRank, and Karma Domain Metric for the same bulk list.

Is this tool free?

Yes — no signup. Save the share link to rerun the same names, or open Karma.Domains for portfolio filters and full reports.

Can a high number get a site in trouble with Google?

A high number is a spam indicator, not proof a host was penalized or banned. Websites that have been penalized — or banned by search engines — need a separate review. They may penalize low-quality tactics; this number alone does not mean a site was flagged as spam.

Should I disavow links after a high score?

Not automatically. Check backlink sources and Google Search Console first. If you find toxic backlinks or harmful backlinks, export a disavow file and disavow only those URLs. Ignoring spam flags is risky. Avoid building spammy placements; building backlinks from spammy links can hurt rankings. Toxic links and bad links still need a human pass before you disavow.

What else should I look at besides spam scores?

Read spam scores with the site's content quality and the domain's backlink profile. Exact-match anchor text, nofollow mix, and thin content on subdomains can raise a website's spam score. Higher spam scores often mean a higher likelihood of risky patterns. Identify risky hosts before you invest.

Who uses these spam scores?

SEO agencies and in-house teams use them to protect SEO performance and healthy SEO. Black-hat SEO and sloppy SEO practices — including building links across multiple sites — can produce spammy link profiles. Check Moz data here, then check the spam score again after cleanup.

How can I run more checks after the free daily limit?

Upgrade to the Pro plan for higher limits inside Karma.Domains.

Is there a Chrome extension for these checks?

Yes — the free Karma Domains Chrome extension shows domain age and Karma Metric on Google, Bing, and DuckDuckGo results, and runs the same Checks from the popup. Install once, then check domains while you search.

Where can I browse expired domains to buy?

Alongside this free check, the full list of expired domains from 49 lists across 32 platforms (auctions, drops and buy-now listings) is on the Karma.Domains homepage, updated hourly.
