I'm a bit old school in that I always trust human review and management over complete automation. Over the years Google has pushed agencies and advertisers to rely on AI and programming for bid management. Now there is manual bidding, enhanced bidding, and a variety of automated bid strategies based on campaign goals. It seems that enhanced bidding is the only one that provides the granular control of individual keyword bids whereas the other automated bidding strategies you are trusting Google. My goal always is to provide the best ROAS with the lowest ad spend and maximum client goals (e.g. sales, leads, etc.) Which bidding strategy have you found works the best for generating the most leads and sales with the lowest ad spend? Has anyone done a comparison in Google Ads campaigns they've managed or can find studies that show automated bidding strategies outperforming the enhanced CPC strategy?
