YouTube campaigns are managed in Google Ads, which makes their tracking straightforward with BrainyMetrics. The account-level final URL suffix tags YouTube clicks with campaign, ad group and ad ids, and the Google Ads integration syncs their spend.
From there, YouTube ad clicks are attributed like any other paid click, through leads, calls and sales, and conversions can be uploaded back to Google with enhanced conversions. For views without clicks, add a "How did you hear about us?" question and compare self-reported YouTube answers with click data.
