Competitor keyword research is based on the idea that the keywords driving most of the traffic in your niche have already been found.
Online businesses in your niche have spent years of trial and error finding the keywords that your customers type into Google when they're looking for your products or services.
So why reinvent the wheel?
You can simply use a keyword research tool to find which keywords are driving your competitors’ traffic.

Competitor Keyword Research in SEMrush
One of the best tools available for doing competitor keyword research is SEMrush.
In this tutorial, you'll learn how to use SEMrush to uncover your competitors’ top performing keywords.
Step #1. Identify Your Competitors in SEMrush
First, we’re going to let SEMrush identify who our competitors are.
SEMrush has a vast database of keywords and traffic stats and it can use that information to quickly identify who your main competitors are.
To do this, login in to your SEMrush account, click on ‘Domain Overview’, and type in your website URL. In this example, I’m going to use the popular blogging tips website blogtyrant.com:
Click ‘Search’ and then scroll down and click on the ‘Competitive Positioning Map’:
The Competitive Positioning Map will show you the sites that SEMrush believes are your main competitors. You need to check that these are in fact your natural competitors.
Maybe you already know who your main competitors are?
In that you don’t need to use the competitors that SEMrush identifies. Simply type your own URLs into the four competitor fields (Step #3)
Step #2. Validate the ‘Competitive Positioning Map’
In my experience, the websites that SEMrush shows in the competitive positioning map are not necessarily sites that produce the kind of content that I’m focussing on.
One of the reasons for this could be that SEMrush bases its analysis on your top performing pages and not on your overall content. That can skew the results and produce a list of websites that you wouldn't necessarily think of as your natural competitors.
So the first thing to do is to make sure that the Competitive Positioning Map accurately identifies your main competitors.
Step #3. Use the ‘Keyword Gap’ Tool
If it's correct, the next step is to click on ‘Keyword Gap’ in the left hand menu:
On the next screen, you’ll see four text fields, each with a dropdown containing your four main competitors:
When you choose one of these competitors, SEMrush will populate the next dropdown with an additional competitor:
Fill each box with a competitor and then click ‘Compare’.
SEMrush will now show you seven categories of keywords, based on competitor analysis. The two categories we are interested in are ‘missing’ and ‘untapped’:
‘Missing’ keywords are “keywords for which the You-domain doesn't have rankings but all of the other entered competitors do”.
‘Untapped keywords’ are “keywords for which the You-domain has no rankings but at least one of the other competitors do”.
Click on ‘missing’ and you’ll see five columns showing which of the websites (your site + 4 competitors) ranks for that keyword.
At the far right, you’ll see five columns with keyword metrics such as search volume, keyword difficulty, and number of results:
Step #4. Use Filters to Find Easy-To-Rank Keywords
There’s a problem with competitor keyword research and you may already have spotted it.
Just because your competitors rank for a particular keyword doesn't mean that you can. If your competitor has a domain authority of 75 and you have a DA of 35, it’s going to be hard for you to rank for some of your competitor’s keywords.
The way to deal with this is to use the filters in the Keyword Gap tool.
- Filter for Keyword Difficulty
Click on the Keyword Difficulty filter and choose ‘possible’, ‘easy’, or ‘very easy’ (depending on how high or low your website’s DA is):
- Filter for Number of Results
Another way to ensure that you only see keywords you can rank for is to filter for a maximum number of search results.
In general, the more results there are in organic search, the more competitive the keyword is going to be. To find less competitive keywords, place a limit on the number of search results that a keyword has.
To do this, click on ‘Advanced filters’ and set the conditions to ‘include results with less than x number of results’.
In this case, I’ve set it to 50M but that number will depend on what sort of niche or industry you are operating within:
Step #5. Percentage of Traffic Per Keyword
A very revealing aspect of competitor keyword research is to see what percentage of a competitor’s total traffic each keyword is responsible for.
For every website, you will usually find that a handful of keywords are driving 15% to 50% of the website's total traffic.
But to see this data, you have to leave the keyword gap analysis tool and look at your competitors one at a time.
Go back to ‘domain overview’ and type in the url of a competitor:
Then click on ‘Top Organic Keywords’:
On the next screen, you’ll see the top 100 keywords for that website.
Toggle the third column so that it shows traffic percentage from high to low. You’ll now see which keywords are driving most of that website’s traffic.
In this instance, we can see that seven keywords are driving just over 10% of Blog Tyrant’s traffic:
But with other websites you’ll often see a small number of keywords driving a much larger percentage of the website’s traffic.
For example, with prontomarketing.com, fourteen keywords are driving 56% of the website’s total traffic:
With buffer.com, seventeen keywords are driving nearly 48% of their traffic:
In the case of wpbeginner.com, fifteen keywords are driving over 28% of title traffic:
And for writtent.com, a mere 12 keywords are driving a massive 80% of the site’s total traffic:
From the point of view of competitor analysis, this is vital information.
After all, if a website is ranking in the top 100 positions for 18K keywords but fifteen of those keywords are responsible for 30% of the website’s traffic, that helps you narrow down your focus. You can spend your time and energy where it’s going to have the greatest effect.
