Microsoft sent emails to some Microsoft Advertising advertisers to let them know that if they have run an import from Google Ads to their Microsoft Advertising account, going forward, Microsoft will continue to automatically import your Google Ads conversion data to your Microsoft Advertising campaigns.

This email was shared by Kirk Williams who posted it on X – he said, “Heads-up if you currently import from Google to Microsoft, they’ll automaticaly import your conversions (and possibly mess stuff up!!!) in the next few weeks so you might want to shut that auto-import function off.”

The email reads:

This is something everyone who does Microsoft Advertising should be aware of.
