22 Top Keyword Research Tools


1. SemRush Best Keyword Research Tool

If you’re serious about SEO, then you must check out SEMRush.

SemRush is one of the best Keyword Research Tools out there. SEMRush is a “Paid” Keyword Research Tool. Let’s find out why SEMRush is known as one of the best Keyword Tools out there.

To start let me tell you that SEMRush works a “little differently” than most other keyword research tools out there. Here, you have two different options. You can research for the keyword by entering the main keyword, and it will suggest you related keywords with their difficulty score.

The second and my favorite way is to research for the keyword is by spying on competitors keyword. SEMRush gets you the keywords that your competition is already ranked for. Now, it should be noted that these are outside-the-box keywords that are rather impossible to get using any other tool.

Let’s see how SEMRush works.

First, you need to enter the competitor’s domain name or its URL which it is ranking for a particular keyword in the field that is shown at the top of the page. In case, you want to do SEO for a country outside the US (let’s say, Google.co.uk), then you can choose and see information about that particular market. You need to select that country from the menu. Once, you do this; you get to see the results. There’s the “Organic Search” section.

Let’s get to know the different terms in this section:

  • First, it shows the SEMRush Rank where you get to see the site’s ranks in the SEMRush Database. It’s based on total estimated organic traffic.
  • Then it shows the Keywords that give the estimated number of monthly organic visitors from Google.
  • Third and the last term is Traffic Cost. It shows you how valuable the traffic is which is based on Google Ads CPC.

So, if you find a domain that has a lot of Organic Search Traffic but a low Traffic Cost, then you can make out that although they are ranking for keywords, their visitors don’t really convert well into buyers.

However, that’s not all with SEMrush.

The real value of SEMRush lies in its “Organic Keywords” data:

The box goes on to show five of the top keywords for which your competitors are ranking for. You can also click on “View full report” and get the complete list of all the keywords that the site or URL ranks for. This itself will give you a handful of solid keywords.

However, if you want more keyword ideas, then go back to the domain’s overview and inspect the “Competitors” in the sidebar. You will get to see that site’s first-page competition.

Clicking on one of these results will let you see the exact search queries they are ranking. You end up digging up some real gems.

All said you could also do your SEMrush search with a keyword instead of using a competitor’s site. Here, you get a “Phrase match report” with a list of long tail keywords that has the keyword you entered. It pulls keyword suggestions from SEMRush massive database of 800+ million terms.
