Leads ads on Facebook have been generating very good results for the client accounts I manage.
The cost per lead is coming lower than Google AdWords and its interesting to see which age & gender is responding best to our ads, this is something we cannot easily know in Google Adwords.
During last year I have noticed that Facebook has rapidly improved their ad platform in almost all aspects including the targeting options, available ad formats as well as the interface to create and manage ads.
Facebook lead ad remarketing
An interesting feature, added quite recently is the ability to remarket to people who interacted with your lead form but did not submit the form.
This audience is potentially very valuable because they took interest in the ad offering and almost reached the point of conversion. I am testing this in some accounts and the results so far look interesting.
