Google Ads is fantastic, but it does not have a dynamic ValueTrack parameter for campaign names (like it does for {adgroupid} or {keyword}). Because Google Ads can't dynamically inject the correct campaign name, HubSpot's tracking is forced to hardcode the utm_campaign name and the hsa_cam (Campaign ID) into your tracking template at the campaign level.
Campaign Mix Experiments allows you to select existing campaigns and assign them to different experiment arms (up to 5 total). This approach offers flexibility in testing various scenarios, including: Account structure testing: Evaluate which campaign combinations are ideal for your business objectives. Campaign consolidation: Test the impact of consolidating multiple campaigns into a single campaign.
