Depending on your subscription plan, Ahrefs Site Explorer puts certain limitations on the number of search positions you can see in “Organic Keywords” report.
Note that these limitations do not concern the number of keywords you will be able to see, but the keywords’ positions that a given website or URL ranks at.
For instance, if you have the Lite subscription, you’ll be able to see only those keywords that a website ranks for within top 20 of organic search results. It might as well rank for a bunch of other keywords at any position below 20, but they will be hidden in our interface.
It doesn’t mean you’ll be able to see only 20 keywords as there can be hundreds of keywords that a website ranks for in top 20.
On the other hand, if you don’t see any keywords at all, it means that a target website doesn’t rank in top 20 for a single keyword yet. Or in particular cases, it can rank for very specific low-demand keywords that we don’t have in our database.
The number of positions you can track depends on your subscription plan (you can find more details about our plans and pricing here: https://ahrefs.com/pricing-plans).
With a Standard plan, our report will show you the keywords that your target website or URL ranks for in top 50 organic search results. And both Advanced and Agency plans allow you to track all the keywords that a website/URL holds in top 100 search results.
