So a few weeks ago I shared a case study on CPM, I thought id share another with a few details on how i plan my campaigns. This time I shan't be sharing my advert as it is still converting well for me. Typically I target no more than 15,000 people per advert, the reason being I want my target audience to have every opportunity to see the advert, think about it it is so easy to miss an advert so I like to play on Frequency. This advert had a frequency of 11.5 which means each potential clicker had the advert displayed to them enough times for them notice it and to think about clicking it. So keeping the target user numbers below 15,000 allows for a higher frequency. When selecting my target audiences "interests" I like to add several related interests for example "dogs, Dog toys, Dog balls" (please don't go try targeting those people it is simply an example) The reason why is i found the target users with more of those interests on their profile where shown the advert very quickly and they where highly targeted. (I ran several adverts testing this, and every time my dummy Facebook account saw the advert with in minutes of the advert going live). Right time for a picture, for those of you who are american I am sorry but the picture is all in GBP not dollars. My bid for this campaign was £0.55 CPM. As you can see i achieved a CPC of £0.008 (which is roughly $0.005 so 2 clicks per cent) I hope this helps people as it has worked well for me.
