Free Moz Spam Score Checker
Moz Spam Score is a percentage from 1% to 100% that measures how closely a site resembles ones Google has penalized, and this checker returns it free.
The score reports the share of sites with a similar profile that Moz found penalized or banned in Google. It is a correlation, not a verdict. A site at 40% is not 40% penalized. It shares traits with a group where 40% of sites got hit.
Read it in bands. Moz treats 1-30% as low, 31-60% as medium and 61-100% as high. Most healthy small sites land under 20%. The number climbs from thin content, a handful of pages, missing contact details, or a link profile dominated by low-quality domains.
If your own score is high, fix what is structurally missing before you touch links. If a link prospect's score is high, that is a reason to skip them rather than a reason to worry about links you already have. Disavowing is rarely the right first move, because Google discounts most junk links without being asked.
The score you get here is today's. What actually matters is the direction. A jump from 12% to 35% across one refresh usually means something changed in your backlink profile, and a single check can never show you that. RankPulse records the score daily and emails you when it moves.
Common questions
Does a high spam score mean Google penalized me?
No. Moz built the score from features shared by penalized sites. Your site can score 45% and rank fine. Treat it as a smoke alarm, not a fire.
Should I disavow links because of my spam score?
Usually no. Google discounts most low-quality links automatically, and a careless disavow file removes links that were helping you. Disavow after a manual action in Search Console, not before.
How do I lower my spam score?
Start with what you control: real contact details, an about page, more than a few pages of content, outbound links to real sources. Those flags are fixable in an afternoon. Your link profile mostly is not.
A one-off check tells you today's number. RankPulse checks every morning and emails you the day it moves.
