Ad signals from Meta Ads
Meta Ads is one of the channels that can feed Ad Engagement Signals. There is no separate Meta Ads signal to set up. You build one signal and tick the channels it should draw from, so a company engaging on two channels arrives as one company rather than two.
What Meta Ads contributes
Website visits from companies that clicked your Meta ads, counted the same way as Google Ads and matched to companies by domain.
Meta reports no company-level engagement of its own, so a company surfaced through Meta Ads alone is surfaced on its visits.
Turning it on
When you create a signal, Meta Ads appears in the channel list. It is selectable once Meta Ads is connected and included in your plan. If it is listed but cannot be picked, the reason is shown beside it.
Everything else about signals, who qualifies, where they go, what lands in your CRM and how often, is the same whatever channel feeds them. See Ad Engagement Signals.
