Google Ads SKAG Builder Script - For MCC & Individual Accounts

Update December 2021 - Code updated to include ability to handle x day time periods (previously you could only use set options such as Today, Yesterday, Last Week, etc, essentially like the Google Ads interface, minus the "All Time" option), as well as to include/exclude "Added" search queries.

Update October 2021 - Code updated to create responsive ads (also with keyword insertion in the headline) in the new SKAGs. The script will also create a new responsive ad when the original ad group doesn't have a responsive ad to copy over.

Although SKAGs have somewhat gone out of style over the last few years, I'm still a fan of them for high impression queries, or really any query that I might want to really focus on with highly targeted ad copy.

There are already some good, free SKAG builder scripts out there (Ad Evolver's Automated Single Keyword Ad Groups for Google Ads being my favourite, and might be better suited to your needs than my script), but as I was looking for more control over which queries would become SKAGs, I wrote a script that allows for query filtering, as well as some other bits and bobs.

Full list of features are:

  1. MCC version

  2. Filtering for certain metrics - conversions, impressions, CPA and ROAS

  3. Date range filtering

  4. Toggle between creating your SKAGs in an EM only campaign, or in the campaign in which the query was triggered

  5. Toggle between EM only and PM/EM SKAGs (I removed BMM following Google's decision not to support it anymore)

  6. Include/Exclude 'close variant' queries

  7. Include/Exclude query filtering (useful if you don't want a SKAG of a rival brand, for example, or if you only want to create a SKAG for 1 out of x possible queries)

  8. Insert query into first headline of SKAG ad (Proper Cased)

  9. Filter out queries longer than 30 characters (useful if you only want to target queries that you can insert into the headline, for example)

  10. Include/Exclude campaigns

  11. Include/Exclude "Added" search queries

To create SKAGs in an EM only campaign, you'll first have to create a campaign in Google Ads with the suffix that you specify in the script itself (default is ' - [E] SKAG'). Other than that, all the options are controlled from within the script, which is (hopefully) clear enough to follow.
