I haven’t had much time to blog lately so I had one of my A4D media buying team members write up something cool that we’re doing to figure out how Yahoo Gemini’s algorithm works.
Consistent ad delivery is the bane of every advertiser that uses Yahoo Gemini. Here’s how you can use data from your Yahoo campaigns to better understand their algorithm.
To an owner of online advertising real estate like Yahoo, all that matters is an ad’s eCPM (effective cost-per-thousand impressions). To a publisher, it’s pretty much “earnings-per-thousand impressions”, because it’s the dollar amount of which you end up paying them to advertise. On Yahoo, if you’re bidding on CPM, that’s also your eCPM. If you’re bidding on a CPC, then eCPM is calculated as “CTR x CPC x 1000”. The higher your eCPM, the more Yahoo should theoretically be delivering your ad. Theoretically, that is.
