Although not the most technical post it is really useful if you are considering using the channel or are new to the system.

The video which I will link to gives a really good round approach to the system and answers some of the common questions I am commonly asked about running these types of ads.

It easily explains some of the metrics the system uses such as ‘ad quality score = bid x est. action rate + and quality’.

There are some interesting points on how to understand what has led to you seeing and ad.  The “Why Am I Seeing This?” link can explain the detailed targeting options that an advertiser has used to target the ads, if off-facebook activity has been used it is explain how this data can be removed for your account.
