Moz’s Link Data Used to Suck… But Not Anymore! The New Link Explorer is Here – Whiteboard Friday
Posted by randfish
Earlier this week we launched our brand-new link building tool, and we’re happy to say that Link Explorer addresses and improves upon a lot of the big problems that have plagued our legacy link tool, Open Site Explorer. In today’s Whiteboard Friday, Rand transparently lists out many of the biggest complaints we’ve heard about OSE over the years and explains the vast improvements Link Explorer provides, from DA scores updated daily to historic link data to a huge index of almost five trillion URLs.

Howdy, Moz fans, and welcome to another edition of Whiteboard Friday. This week I’m very excited to say that Moz’s Open Site Explorer product, which had a lot of challenges with it, is finally being retired, and we have a new product, Link Explorer, that’s taking its place. So let me walk you through why and how Moz’s link data for the last few years has really kind of sucked. There’s no two ways about it.
If you heard me here on Whiteboard Friday, if you watched me at conferences, if you saw me blogging, you’d probably see me saying, “Hey, I personally use Ahrefs, or I use Majestic for my link research.” Moz has a lot of other good tools. The crawler is excellent. Moz Pro is good. But Open Site Explorer was really lagging, and today, that’s not the case. Let me walk you through this.
The big complaints about OSE/Mozscape
1. The index was just too small
Mozscape was probably about a fifth to a tenth the size of its competitors. While it got a lot of the quality good links of the web, it just didn’t get enough. As SEOs, we need to know all of the links, the good ones and the bad ones.
2. The data was just too old
So, in Mozscape, a link that you built on November 1st, you got a link added to a website, you’re very proud of yourself. That’s excellent. You should expect that a link tool should pick that up within maybe a couple weeks, maybe three weeks at the outside. Google is probably picking it up within just a few days, sometimes hours.
Yet, when Mozscape would crawl that, it would often be a month or more later, and by the time Mozscape processed its index, it could be another 40 days after that, meaning that you could see a 60- to 80-day delay, sometimes even longer, between when your link was built and when Mozscape actually found it. That sucks.
3. PA/DA scores took forever to update
PA/DA scores, likewise, took forever to update because of this link problem. So the index would say, oh, your DA is over here. You’re at 25, and now maybe you’re at 30. But in reality, you’re probably far ahead of that, because you’ve been building a lot of links that Mozscape just hasn’t picked up yet. So this is this lagging indicator. Sometimes there would be links that it just didn’t even know about. So PA and DA just wouldn’t be as accurate or precise as you’d want them to be.
4. Some scores were really confusing and out of date
MozRank and MozTrust relied on essentially the original Google PageRank paper from 1997, which there’s no way that’s what’s being used today. Google certainly uses some view of link equity that’s passed between links that is similar to PageRank, and I think they probably internally call that PageRank, but it looks nothing like what MozRank was called.
Likewise, MozTrust, way out of date, from a paper in I think 2002 or 2003. Much more advancements in search have happened since then.
Spam score was also out of date. It used a system that was correlated with what spam looked like three, four years ago, so much more up to date than these two, but really not nearly as sophisticated as what Google is doing today. So we needed to toss those out and find their replacements as well.
