How to set up A/B tests in Google Ads
Why run A/B tests in Google Analytics with Corvidae data
Background
Once rebuilt, Corvidae attribution data can be used by clients inside their own Google Ads accounts to reduce costs and increase conversions, resulting in significant improvements in their paid media campaigns.
Using Corvidae’s Data Driven Attribution (DDA), newly stitched customer conversion paths have an increased number of touchpoints and attribute revenue more effectively for potential converting customers.
Google Ads uses GCLIDs to understand conversion behaviours, Corvidae stitches many more into converting paths giving Google improved data for their own algorithm to use in its ad placements.
Rationale
Longer conversion paths allow Google to reduce the cost of new customer acquisition in its own ad platform, reducing your CPA and capturing more new customers than would otherwise be possible.
This is because Corvidae paths will stitch GCLIDs that Google has not attributed to converting paths as without Corvidae’s unique AI path stitching, it is unable to join cross device and session data effectively.
Running A/B Split Tests to Prove Corvidae Efficiencies
By creating a secondary conversion action in the client Google Ads account, Corvidae data can be used to run A/B split tests.
These are set up with existing customer campaigns using the same creative, with budget split 50/50. The only tested change is to use Corvidae data for one and Google data for the other.
Impact of A/B Split Tests
We have seen several positive results from these tests:
Lower CPC (Lower CPC and CPA)
Higher ROAS (up to 100% increase)
Higher net new customers (over 25%)
Higher overall conversions (over 25%)

Viewing the results of your Google Ads A/B Test
Because Google only shows the additional conversion generated by the new conversion action, we need to add the results column to see the total conversions. The results can only be viewed in the campaign tab as the Experiment results tab will only show the Corvidae new sales not the total sales.
