Low Q Content/Ads. What metrics and benchmarks does Facebook use to determine whether they penalise your ads?Low Q Content/Ads. What metrics and benchmarks does Facebook use to determine whether they penalise your ads? Is there an estimate e. g. CPM, Link click cost etc that you as a marketer can use to determine this? I wouldn't ask the question ecept I couldn't find a reasonably recent/accurate post on Google Re: this. or on Facebook Help pages. :(
