Serpstat Has 2.4B Keywords In Google USA Database — Comparison With SEMrush

Serpstat Has 2.4B Keywords In Google USA Database — Comparison With SEMrush
Vera Zhukova
Customer Success Manager at Serpstat
We have some extraordinary news for you: our Google USA database is updated to 2.4B keywords in search and 160M in competitor analysis! Not bad, right? :)

In this article, I'll tell you more about the growth of our base, and why Serpstat is the best solution for working with keywords in the US Google database.
Before we start, do you know that Serpstat now has 230 Google databases covering search queries and SERPs from all over the world? No matter which country you need data for, Serpstat has everything for qualitative keyword research and competitive analysis.

Serpstat vs. SEMrush

I compared the Serpstat data with the information available from another tool not to make empty claims that our database is the largest. I chose the leading SEO tool SEMrush as a benchmark. I highlighted 6 niches and took 10 relevant keywords and 10 domains that are the leaders in the niche:

  • electronics
  • real estate
  • cars
  • games
  • home appliances
  • general merch

I chose 2 values that denote the database for analysis:
Number of keywords for a search query
Number of keywords for a domain
* at Semrush we used the Broad match sorting.

This in-depth analysis shows that Serpstat provides more comprehensive data for most keywords and topics, for both keywords and domains.

If you have special needs for one or more modules, contact our account managers to create a custom plan.


We use two indicators for keywords. The larger one is used to analyze search results for the queries. The smaller one displays statistics on search queries for which domains are ranked. First of all, let's see how we changed the number of keywords:

More keywords

Now in Serpstat you'll find even more keywords for collecting and compiling semantics for your site! I collected 10 popular search queries and checked them through the Serpstat database. Just look at these statistics! Our base has become bigger, and you can check it yourself. Follow the links in the report below and see how large the database of keywords of our service is:

More domain keywords

The database of keywords by domains has also become larger. Now competitor analysis has become even easier, and you can monitor the position of your site even more effective :) I compared the number of keywords in 10 popular domains before and after our update. You can see the keyword database which Serpstat has for these domains. Just follow the links below:
You can always see the total number of keywords for each database at Statistics page.

USA database timeline

To see how we developed and expanded our USA database, we dug through the archives and collected the history of our updates. Here is a timeline for you to assess our work :)

Keyword selection

We update our databases regularly:
First, we look for keywords in various sources :)
Then we check them for rubbish to delete phrases with a frequency close to zero or equal to zero, in other words, rubbish keywords. Then we add the remaining keywords to our database.

What do we mean by "rubbish keywords"?

  • keywords that are longer than 100 characters
  • keywords with an unnatural set of letters or words
  • keywords with incorrect characters
  • double words
  • low-volume keywords
  • queries with an incomplete meaning
  • keywords with artificially increased volume
  • outdated keywords.
Over time, some keywords that are in the database are no longer relevant. Therefore, the base is regularly rechecked for rubbish.
We do our best to ensure that our users receive the complete data for all databases and take into account the needs of the entire audience. As a result, the most popular databases are being significantly updated, including the USA database, which is currently the largest available Google database with 2.4B keywords and 160M search terms for domains.
