Okay, now we’re talking our own language

Now you might ask, if Ahrefs is so fast at crawling, how can Moz catch up? Well, there are a couple of answers, but perhaps the biggest one is that new URLs only represent a fraction of the web. Most URLs are not new. Let’s say two indexes (one new, one old) have a group of URLs that they are considering crawling. Both may prioritize URLs on important domains that they have never seen before. For large, old indexes, this will be a small percentage of that group because they have been crawling faster for a long time. So, during the day, a higher percentage of the old index’s crawl will be dedicated to recrawling pages that it already knows about. The new index can devote more of its crawl capacity to new URLs.

However, this puts pressure on Moz to improve its bahrain number data infrastructure as we catch and overcome Ahrefs in some size metrics. According to this post, Ahrefs is winning the fast crawl metric.

Quality
. This is the most important thing, in my opinion. What’s the point of building a link graph to help SEO people if it’s not like Google? While we had to temporarily cut out some metrics, we found some that are really important and worth taking a look at.


Domain index matches
What is the probability that a random domain shares the same index status in Google and Link Index?


Domain index matches try to determine when a domain shares the same index status with Google as it does in one of the competing link indexes. If Google ignores a domain, we want to ignore the domain. If Google indexes a domain, we want to index the domain. If we have a domain that Google doesn't, or vice versa, that's bad.
