We connected Hubspot to our Facebook Ad account for reporting, tracking ans syncing using Lead Gen Forms. We manage all of our ads using FB Business Manager Directly.
We do not use Hubspot to edit, or publish ads, yet for some reason some of our FB ads say “Published by Hubspot Ads”.
If the auto-tracking is enabled in your connected Facebook Ads accounts, for
some ads, when we apply our tracking through the auto-tracking feature, Facebook adds the tag “Posted by HubSpot Ads” even though the ad is not posted in HubSpot.
This is not very consistent and neither Facebook nor us can see 100% when it will or when it will not, but this is not unexpected behavior.
It’s just a Facebook tagging issue that happens sometimes.
