One of the most helpful functions of modern-day SEO software is the idea of a “keyword universe,” a database of tens of millions of keywords that you can tap into and discover what your site is ranking for. Rankings data like this can be powerful, and having that kind of power at your fingertips can be intimidating. In today’s Whiteboard Friday, Rand explains the concept of the “keyword universe” and shares his most useful tips to take advantage of this data in the most popular SEO tools.

Howdy, Moz fans, and welcome to another edition of Whiteboard Friday. This week we’re going to chat about the Keywords by Site feature that exists now in Moz’s toolset — we just launched it this week — and SEMrush and Ahrefs, who have had it for a little while, and there are some other tools out there that also do it, so places like KeyCompete and SpyFu and others.
In SEO software, there are two types of rankings data:
A) Keywords you’ve specifically chosen to track over time
Basically, the way you can think of this is, in SEO software, there are two kinds of keyword rankings data. There are keywords that you have specifically selected or your marketing manager or your SEO has specifically selected to track over time. So I’ve said I want to track X, Y and Z. I want to see how they rank in Google’s results, maybe in a particular location or a particular country. I want to see the position, and I want to see the change over time. Great, that’s your set that you’ve constructed and built and chosen.
B) A keyword “universe” that gives wide coverage of tens of millions of keywords
But then there’s what’s called a keyword universe, an entire universe of keywords that’s maintained by a tool provider. So SEMrush has their particular database, their universe of keywords for a bunch of different languages, and Ahrefs has their keyword universe of keywords that each of those two companies have selected. Moz now has its keyword universe, a universe of, I think in our case, about 40 million keywords in English in the US that we track every two weeks, so we’ll basically get rankings updates. SEMrush tracks their keywords monthly. I think Ahrefs also does monthly.
Depending on the degree of change, you might care or not care about the various updates. Usually, for keywords you’ve specifically chosen, it’s every week. But in these cases, because it’s tens of millions or hundreds of millions of keywords, they’re usually tracking them weekly or monthly.
So in this universe of keywords, you might only rank for some of them. It’s not ones you’ve specifically selected. It’s ones the tool provider has said, “Hey, this is a broad representation of all the keywords that we could find that have some real search volume that people might be interested in who’s ranking in Google, and we’re going track this giant database.” So you might see some of these your site ranks for. In this case, seven of these keywords your site ranks for, four of them your competitors rank for, and two of them both you and your competitors rank for.
Remarkable data can be extracted from a “keyword universe”
There’s a bunch of cool data, very, very cool data that can be extracted from a keyword universe. Most of these tools that I mentioned do this.
Number of ranking keywords over time
So they’ll show you how many keywords a given site ranks for over time. So you can see, oh, Moz.com is growing its presence in the keyword universe, or it’s shrinking. Maybe it’s ranking for fewer keywords this month than it was last month, which might be a telltale sign of something going wrong or poorly.
Degree of rankings overlap
You can see the degree of overlap between several websites’ keyword rankings. So, for example, I can see here that Moz and Search Engine Land overlap here with all these keywords. In fact, in the Keywords by Site tool inside Moz and in SEMrush, you can see what those numbers look like. I think…
