Scaling Content Gap Analysis with SEMrush

Content Gap Analysis can be an intricate and exhaustive process. But with a little excel work and a few SEMrush exports, you can do it in a matter of minutes. It’s almost summer, so let’s use grilling blogs as the example:

For this post, I’m performing content gap analysis on BBQ Addicts (They sell bacon explosions, they have my unwavering loyalty), and we’ll use the following competitors:

 Step 1 – Open up SEMrush and search for


Step 2 – Go to the Full Report for Organic Keywords

Full Report for Organic SEM Rush

Step 3 – Export all organic keywords… if there aren’t too many.

We’re going to be man handling some data in excel, and SEMrush exports can be HUGEIf you are analyzing competitor sites that you compete with in the SERPs for content, but don’t compete with on a product level –  use the filters in SEMrush to narrow down your results. For example, Weber Grills is a huge site, so to narrow down the results – you can remove the bulk of their ecommerce catalog.


Step 3.1 Export Keywords

Export Full Keywords from SEMRush

(Just my preference, but I like to export as a csv then copy over into a .xls file)

Step 4 – Follow the same process for all competitors

Note: do not combine exports yet

Step 5 – Remove keyword duplicates from all individual exports


Step 6 – Compare SEMrush

Add the SEMrush data from first competitor (Kevin’s Backyard – the blog on Weber Grills) to the same excel sheet as the BBQ Addicts data. For this process, its best to find where content lives on the competitor’s site, and then use landing page urls in the report to suss out directories and subdomains that are unnecessary and irrelevant to your gap analysis.

After a quick scan of the urls you can figure out where most of the content lives and what category pages lead to what parts of the site:

  • /backyard/
  • /recipes/
  • /grillout/

This excludes the following product, brand and ecommerce oriented areas

  • /grills/
  • /accessories/


Step 7 – Remove all branded terms

Step 8 – Identify Content Overlap

Compare your data set to one competitor at a time. Use conditional formatting to highlight duplicates, then sort the keyword column by cell color.


Step 9 – Remove Duplicates

At the top of your excel sheet is your overlapping content.


Save these for later, you can use this data to report on current content overlap.

Step 10 – Do it All Over Again

Copy your remaining data set, but make sure  to leave behind your competitor’s data.  Paste in a new excel sheet, repeat steps 6-9 until you’ve gone through all competitors.

Step 11 – Combine Data

Combine all competitor data that doesn’t overlap with your sites content into one excel sheet.

Step 12 – Pivot Table Time

Now turn all this data into a pivot table.


Quickly determine which competitor urls are cleaning up in the long tail



 Download the Excel Doc

In case you want to see how this excel doc/pivot table is set up, you can download it here.

Also, if you haven’t used SEMrush before, you can poke around in the tool for free, it has a ton of other uses (especially for PPC) you just can’t export anything in the free version and there is a limit of calls per day.


Optional Step 13 – Find duplicate keywords in Raw Data

If you want to see how your competitors are approaching content differently, use conditional formatting to identify two or more competitors with overlapping content

Wow John! What a coincidence, I'm actually developing a software that does Step 1-7 with the click of a button. Here's how it'll work.

You enter a URL and the software will do the following:
1-Crawl your website for all your landing pages.

2-Analyze your pages content and come up with a list of currently ranking terms, and keywords you can possibly rank for.
2.1 Assign a Rankability and KEI value to each keyword.
2.2 Actually track the ranking of each keyword in real time(daily).
2.3 Keep generating new keywords from already existing keywords to find ranking opportunities.

3. Besides the Volume data from Keyword Planner, it'll also use the data from Google Analytics and Google Webmaster Tools, correlate and extrapolate to come up with what I'm calling "True Traffic".

4. The value for "True Traffic"(trademarked, lol) will only get accurate over time as it tracks and analyze historical Analytics and GWT data.

5. Would-be-nice feature: Add a tracking pixel so you can track actual conversion and measure actual keyword ROI (again).


p/s: Is it OK if I add you to my personal list of people that might be interested to give this app a whirl once it's done mid-Jan 2014? It's totally cool if you say no, I'll still come to your blog :)

@Al Mukmin Hey dude, yeah - I will check it out. Let me know when it's finished, just hit me up on Twitter.

Thanks for checking out the blog!


Nice article definitely helpful for those who have experience in link building


LOVE SEMRUSH! Great Article John, got any writers/services you could suggest?


Thanks for this great post. The walkthrough is particularly didactic. 


Awesome post. While SEMrush tends to provide bad ranking data in my experience, their other competitive analysis tools are pretty spot on. This is a prime example of how to use these to your advantage. Thanks for writing this up.
