Adword Conversion Optimizer and how does it work?

Hi,

I want to use Adword Conversion Optimizer on My campaign. But I am not able to use it because the option Focus on conversions (Conversion Optimiser) - use CPA bids in Bidding and Budget setting due to it is Disable. Can anyone help me how I can make it enable and use to adwords conversion optimizer.



Is there any option to pay per action or something actually filling up the form then we track it leads.

No. Google does not offer any pay per acquisition model.
What you are seeing is an option that Google offers where their algorithm will automatically adjust your bids to try to get you the best cost per acquisition. If bidding up or down a bit will get you a better CPA it will adjust the bids accordingly.
As shown in the image you do not have enough conversion data to utilize that option anyway.

If you are using Google Analytics you can set up things like filling out a form as having a virtual 'value' associated with them. So you could say 'every person who fills out my form gets me around $0.20 or $2.50' or whatever. Then the ROI figures will reflect that valuation.
