Enhanced CPC is a hybrid of manual and automated bidding strategies. While 'Manual CPC' allows advertisers to set bids for clicks manually, 'Automated Bidding' strategies, including Enhanced CPC, use algorithms to adjust bids. Enhanced CPC specifically refines manual bids using real-time data, aiming to enhance the 'Conversion Rate' and 'Return on Ad Spend (ROAS)'.

In the 'Ad Auction', where ads compete for placement, Enhanced CPC plays a crucial role. It works alongside 'Quality Score', which assesses the relevance and quality of ads. An ad with a higher Quality Score and optimized Enhanced CPC bids has a better chance of winning favorable positions, potentially lowering overall costs.

Enhanced CPC can be part of a broader 'Bid Strategy'. 'Bid Adjustment' is a related concept, allowing advertisers to increase or decrease bids based on various factors like device type or location. Enhanced CPC makes dynamic adjustments based on the likelihood of conversion, complementing these manual adjustments.

While Enhanced CPC adjusts bids to maximize conversions, 'Target CPA' (Cost-Per-Acquisition) aims to achieve as many conversions as possible at a specific cost per conversion. Both are automated strategies, but Target CPA focuses on cost efficiency per conversion, whereas Enhanced CPC enhances manual bids for overall conversion gains.

Enhanced CPC offers a middle ground between 'Manual Bidding' and full automation. Advertisers retain control over base bids while benefiting from automated optimizations. This balance helps advertisers who are not ready to fully commit to automated strategies but want better performance than manual bidding alone can provide.
