Easily find and prioritize the best keywords using a variety of filters

Want to quickly find the ideal topics to target in your list of keywords? Play around with our inbuilt filters.

Using a variety of filters

You can also include or exclude certain terms. For example, if you’re looking for only keywords comparing something, you can use the Include filter to only show keywords with “vs” in it.

Check “Keyword Difficulty” score

Keywords Explorer helps you determine how hard it would be to rank in the top 10 search results for a given keyword by calculating its “Keyword Difficulty” score (on a scale from 1 to 100, with the latter being the hardest).

Keyword Difficulty score

The Keyword Difficulty score is a weighted average of the number of referring domains to the top 10 search results.

Use advanced metrics for deeper insights

Thanks to the clickstream data we use to generate our reports, Ahrefs’ Keywords Explorer shows you a number of advanced metrics you won’t see in any other tool:

  • Clicks — Some searches result in clicks on multiple search results, while others might have none. ‘Clicks’ shows the average monthly number of clicks on the search results for your target keyword.

  • Clicks Per Search — shows how many different search results people click, on average, after searching for this keyword.

  • % of Clicks — shows what percentage of searches for a given keyword result in clicks on the search results.

  • % of Paid Clicks vs Organic Clicks — shows how clicks on the search results are distributed between paid and organic results.

  • Return Rate — a unique Ahrefs metric that compares which keyword gets more repeat searches using a relative scale. For example, a keyword with a Return Rate of 3 simply means that it gets searched more often than a keyword with a Return Rate of 2 (and not merely being searched 3 or 2 times a month.)

SERP and ranking history

See the “Parent Topic” for your target keyword

A single page can rank for hundreds of related keywords. Parent Topic determines if you can rank for your target keyword while targeting a more general topic on your page instead.

Parent Topic

We identify the Parent Topic by taking the #1 ranking page for your keyword and finding the keyword responsible for sending the most traffic to that page.

Review the current SERP and ranking history of top-ranking results

The “SERP overview” report in Keywords Explorer lets you see the top-ranking results, along with all their SEO metrics, at a glance. This is the only report of its kind that brings important SEO metrics like backlinks, organic traffic and organic keywords together.

You can quickly assess the SERP and understand why these pages rank where they do.

top-ranking results

The "SERP position history" report shows you the ranking history of the pages that currently occupy the top 5 positions in the search results. You can use this report as an indication of whether the SERPs for that keyword is very volatile.

For example, the top-ranking pages for "healthy juices" looks pretty stable (i.e. rankings aren't jumping around). This could mean that the keyword is more difficult to crack.
