I have noticed a sudden unseasonal drop in my Adsense earnings this month so decided to investigate. In case you have not realised, Adsense reporting has changed to include some new features. Read the Adsense Blog here.
Unfortunately that did little for my understanding as to why my eCPM has been slowly declining over the past year. Whilst some of this is attributed to new sites yet to perform as well as more mature sites, dragging down my overall CPC revenue, I also noted that there was a marked decline in revenue once ‘placement targeted’ ads started appearing on my sites.
Contextually placed ads are all performing well, but none of the sites are doing well with placement ads – is this because the advertiser is not selecting wisely. If my contextual ads are performing above what I believe is industry average, then there is no reason a well targeted placement ad should not do the same.
This go me thinking – are these advertisers pulling my overall Adsense revenue down – if so, how can I stop placement ads without having to go to the trouble of identifying each of the advertisers and blocking them.
So I went searching to see if this was an option – as yet I have not found anywhere where I as a publiser can control the choice between placement and contextual ads. If there is some option hidden deep, I would appreciate your advice in a comment.
