I use FB advertising to generate leads for my retail education business. We use Adwords too.

CPL via FB is about $1 (we're in India) and the CPL via Adwords is about 80 cents. Conversions: FB is basically garbage, less than .5%, while Adwords does way better and gives a positive ROI.

I have used Adwords retargeting but not FB retargeting, has it been beneficial to anyone?
