Duplicate Query Checker across accounts
Duplicate Get started!

Multiple keywords can be eligible for the same user query. To prevent your data from being scattered all over the place, Brainlabs wrote a great script to find identical query's in different ad groups. We've adjusted the script to look over account borders so you can check for duplicate queries across accounts. And we took the liberty to further enhance the script.

What is does?

The scripts check if a user query is matched to multiple keywords. This could be in the same ad group, across ad groups, and across accounts. If it finds a duplicate, the script then writes the results to a Google Sheet. This way you can easily spot duplicates and create negative keywords to prevent them. The script is tested in MCC's with up to 9 accounts.

Find duplicate search terms across accounts


We've made some improvements to make the script more versatile. Although the majority is still written by Brainlabs, we've added:

  • Adjustable date range
    You can adjust the desired date range in the config now
  • Google Sheet styling
    A fixed first row with the headers in bold
  • Additional settings
    See "Settings" chapter below: extra options are available because the script is adjusted to run on MCC-level


  • SPREADSHEET_URL: The URL of the Google Sheet the results will be put into. This can be an empty Google Sheet
  • ACCOUNT_IDS or LABEL_NAME: Choose if you want to select accounts by Account ID or by applying a label. Leave empty if you want to check all account in the MCC
  • CAMPAIGN_NAME_CONTAINS: Use this if you only want to look at some campaigns
  • CAMPAIGN_NAME_DOES_NOT_CONTAIN: Use this if you want to exclude some campaigns
  • IGNORE_PAUSED_CAMPAIGNS: Set this to 'true' to only look at currently active campaigns
  • IMPRESSION_TRESHOLD: Only queries with more than this number of impressions will be looked at
  • DATE_RANGE: Pick your desired date range. See options here
  • CROSS_ACCOUNT_ONLY: Set this to 'true' if you want to show cross-account duplicates only
  • IGNORE_BMM_EXACT: If your ad groups are split by match type (e.g. BMM/Exact) and you want to ignore duplicates in their match type equivalent ad group, set this to 'true' and fill in the identifiers below
  • BMM_IDENTIFIER and EXACT_IDENTIFIER: See explanation above

Scheduling: No need to schedule this script. Just run it once in a while to check for duplicate search terms across accounts.
