So in general, we manage a 5 figure/month online marketing budget. That is split between Facebook, Google, display ads and retargeting. We focus mostly on highly targeted display ads, retargeting then Google and Facebook, with Facebook being the place we spend the least amount overall.

Why we choose this, is simply because while we see the most traffic from Facebook, the least number of conversions come from those ads. Retargeting and Display Ads do the best, outside of direct emails and follow up from on site visitors.
