CPC and CPA both are marketing tips to promote services/business on search engines. It depends on your services if CPC or CPA is better. You should practice CPC for a month and CPA for another month then compare your result. You will get which one is the best. I also advice you to add Live2Support's live chat on your website if you are investing money on CPC and CPA. Live2support will make it easy to communicate with website visitors when visitors land on your website with the help of CPC or CPA.
