What does a Google Ads agency do?
A Google Ads agency runs your search, YouTube, Display, and Shopping campaigns end-to-end: keyword research, ad copy and creative, bid management, negative keyword pruning, landing page recommendations, conversion tracking, and reporting. The good ones also push back on obvious mistakes (bad landing pages, mistargeted campaigns) that no amount of platform expertise can rescue.
