Who Has The Strongest Keyword Dataset? SISTRIX vs. Semrush vs. Ahrefs

Long term SEO success can only be done by making decisions decisions based on real, trustworthy, transparent data. We compare here our keyword dataset with those of our competitors to find out the main differences and show you why SISTRIX is the best SEO tool, with the best data on the market.

Keywords are one of the foundations of SEO; that’s why they are often a fundamental metric in determining the performance of an SEO tool. However, every tool monitors keyword data differently. We’ll demonstrate this by comparing real data from different tools with those from the SISTRIX Toolbox.

International Comparison

For the first comparison we consider the total number of organic keywords offered by each tool for five relevant countries in Europe.

Today, 64% of searches are carried out on mobile phones, so it makes sense to consider only the mobile database from SISTRIX and Semrush. As far as Ahrefs is concerned, we had to take the desktop database into account, as the tool doesn’t offer any mobile data for keywords.

To Sum Up

In every country that we analysed, SISTRIX has the highest number of organic keywords. On average, SISTRIX has 2 times more keywords than Ahrefs, with the extra advantage that the database refers to mobile results (desktop results are also available on SISTRIX, if needed). As far as Semrush is concerned, the mobile database is between 10 and 50 times smaller than the one from SISTRIX.

This makes SISTRIX the most powerful and complete tool for your content and keyword research. To learn more about keyword research and its importance, read on in our overview article on keyword research here.
