Keyword De-Duper - User Guide

What is it?

The Keyword De-Duper optimization helps you find duplicate keywords in your Google Ads account, within the same campaign or across campaigns and recommends which ones you should keep and which ones you should pause. Duplicate keywords that are present more than once in the same account end up competing against each other and thus dividing the traffic. 

What does it do?

It finds absolute duplicate keywords in your Google Ads account, both within and across campaigns. The system analyzes the data and then suggests the best performing duplicate keyword to keep. The other duplicates can be paused from within the Optmyzr interface with just a click. 

How does it work?

The system uses an algorithm to analyze the data and performance to find which of the duplicates perform better and suggests keeping them and pausing the other ones. You can pause those keywords directly from your Optmyzr account with just one click! 

The Basic mode looks for keywords with the same match type in the same campaign, and the Advanced mode looks for keywords with the same match type across campaigns.

To make sure it suggests exact duplicates (same network targeting and same match type), our system checks for campaign settings like target networks, advertising channels, language, location, age range, carrier, operating system version, mobile device, gender, proximity, platform, and ad schedule. 

If the same keyword is present in two campaigns (for example, one targeting the US and the other targeting Australia), the system will not consider it a duplicate. 

Note: The suggestions by Optmyzr only show duplicates that have had at least one impression. 

Why should you remove duplicate keywords?

Google Ads has to choose between the duplicate keywords to enter in the ad auction, getting the traffic divided, and affecting the performance. Sometimes, none of the duplicates get enough data to determine whether they are performing well or not, what affects the data collection that is required for the optimization.

How to use it?

Selecting parameters

You can choose to use one of two modes:

  • Basic Mode: Look for keywords with the same match type in the same campaign (default).
  • Advanced Mode: Look for keywords with the same match type across campaigns.

Select the keywords you want to keep and press Apply Changes. The system will keep the selected keywords and will automatically pause the rest.

If you need to export the suggestions, you can download a CSV file or a Google Ads Editor file.

Why don't I see duplicate keywords across campaigns?

It might be because the campaign criteria (target location, language, ad schedule, etc.) is not the same for the campaigns that have the same keywords. The optimization doesn't consider them as duplicates, and it will only show results if the keywords have the exact match type, and the campaigns have the same criteria. 


  • You shouldn't have the same keyword (with the same match type, geographic and network targeting) in a Google Ads account.
  • We recommend using this optimization every two weeks (14 days). In case you add keywords more regularly,  you should run it more often.
