It is day 2 of my experiment on running ads on Facebook. Less people clicked through to my site, which is alright for now.

I switched to promoting a post that has affiliate links on it. So far, I have made around $3-4 in commissions from a less than $2 ad spend.

So that's a 50-100% return. If this is sustainable, then it presents an opportunity to diversify the traffic source away from Google.
