When Cobiro creates a campaign after scanning your website, it automatically chooses the Manual Cost-per-Click (CPC) bidding option since our Bidding Engine only works in this setting. Manual CPC bidding gives Cobiro the control to manage all bids for each of your keywords. Every bid that Cobiro sets to optimize your ads, provides our self-learning algorithm with valuable information to continually improve your results. Choosing Google's Enhanced CPC bidding system instead would take away the bidding control from Cobiro and we could not continue to improve your AdWords activities. Letting Cobiro analyze all the available information and set all bids accordingly will ensure to get the most out of your AdWords account.
