Facebook Ads vs Google Adwords: A Comparison

Facebook Ads vs Google Adwords – A Comparison Which one works best? Faceook advertising or Google Adwords? When we launched our product globally we decided to run campaigns on both Google and Facebook. I put equal amount of money on Google Adwords and Facebook for CPC campaigns. I also ran similar campaigns with more or less the same ad copy to measure the performance on Google and Facebook. Our book products requires users to download the app and then register.

I had some interesting learnings which i would like to share: Over a period of one month I got 10-15% lower CPC on Facebook vis-a-vis Google. The number of registrations from Facebook campaigns was approx 20% more than registrations from Google. Overall CPC campaigns on Facebook were more effective and gave a better ROI than Google.
