Spam Score: Moz’s New Metric to Measure Penalization Risk

Posted by randfish

Today, I’m very excited to announce that Moz’s Spam Score, an R&D project we’ve worked on for nearly a year, is finally going live. In this post, you can learn more about how we’re calculating spam score, what it means, and how you can potentially use it in your SEO work.

How does Spam Score work?

Over the last year, our data science team, led by 
Dr. Matt Peters, examined a great number of potential factors that predicted that a site might be penalized or banned by Google. We found strong correlations with 17 unique factors we call “spam flags,” and turned them into a score.

Almost every subdomain in 
Mozscape (our web index) now has a Spam Score attached to it, and this score is viewable inside Open Site Explorer (and soon, the MozBar and other tools). The score is simple; it just records the quantity of spam flags the subdomain triggers. Our correlations showed that no particular flag was more likely than others to mean a domain was penalized/banned in Google, but firing many flags had a very strong correlation (you can see the math below).

Spam Score currently operates only on the subdomain level—we don’t have … Read the rest

Link Audit Guide for Effective Link Removals & Risk Mitigation

Posted by Modestos

This step-by-step guide aims to help users with the link auditing process relying on own judgment, without blindly relying on automation. Because links are still a very important ranking factor, link audits should be carried out by experienced link auditors rather than third party automated services. A flawed link audit can have detrimental implications.

The guide consists of the following sections:

  1. How to make sure that your site’s issues are links-related.
  2. Which common misconceptions you should to avoid when judging the impact of backlinks.
  3. How to shape a solid link removal strategy.
  4. How to improve the backlink data collection process.
  5. Why you need to re-crawl all collected backlink data.
  6. Why you need to find the genuine URLs of your backlinks.
  7. How to build a bespoke backlink classification model.
  8. Why you need to weight and aggregate all negative signals.
  9. How to prioritise backlinks for removal.
  10. How to measure success after having removed/disavowed links.

Why Big Content Is Worth the Risk

Posted by Dr. Pete

We all want the low-hanging fruit, but let’s be honest – the low-hanging fruit is rotten, bruised, and covered with the grubby fingerprints of all the other spoiled brats pawing at it. There’s a time for easy wins, but easy only gets you so far. Sadly, I see too many SEOs putting days or weeks of effort into crafting the perfect low-value scheme, when that same time could’ve easily gone into content that has real staying power and drives sales.

I’m obsessed with “Big Content” lately – resources that go beyond our narrow bins of blog posts, videos, and infographics. I’m going to show you how that obsession is paying off, and why building real content is easier than you think.

I. What Is Big Content?

First, let me apologize for introducing another important-sounding but vague and probably useless term. I’m only calling it “Big Content” because the examples I’m thinking of defy any single definition. I want this to be actionable, so let me try to pin down what I’m taking about…

1. Big Content Takes Effort

If you want easy, then stop reading (this article is pretty long, and that sandwich won’t eat … Read the rest
