Case Orange (PL)
Period: 11.11.2015 â?? 30.11.2015
Cost: â?¬678,89 ($738,61)
Revenue: 1422,78 $
Profit: 684$
I used banners 300x250, because, as you know, there is great amount of traffic for these very banners.
I have tested about 40 self-made banners in one ad agency, changing bad banners to new ones. At the end only one banner (practically the first one) converted successfully. It wasn't explicit, but it was absolutely repulsive. Thatâ??s gross
but not for Poles!
Its CTR was the best one â?? practically 1,3%.
Later, one more banner started giving profit, however its ROI wasnâ??t enough, so I stopped it.
Iâ??d never stopped monitoring bid in exoclick not to be bargained out. I held the top-bid.
Basically, good banner is 90% of success. The same banner can be used in other campaigns, in case it suits the category))
