# link_google_ads_to_analytics

LINK a GA4 property to a Google Ads account. This is the prerequisite for two things users constantly ask for and cannot otherwise have: importing GA4 key events as Google Ads CONVERSIONS — which is what gets a smart-bidding campaign past the conversion-tracking refusal for a GA4-first advertiser — and using a GA4 AUDIENCE for remarketing. RE-LINKING AN ACCOUNT THAT IS ALREADY LINKED IS NOT AN ERROR: it reports that and changes nothing, because this is exactly the call an agent makes when something downstream is not working. adsPersonalizationEnabled DEFAULTS TO TRUE deliberately — a link with it off is the silent dead end where the audience exists in GA4 and never appears in Google Ads, with nothing reporting an error. The connected Google account needs EDIT on the GA4 property AND admin on the Google Ads account; without the second Google refuses and the refusal reads like a Hermoso fault. Google can take 24-48 hours before an audience shows up on the other side. 0 credits.
