Beginning September our CTR and revenues plummetted like crazy. Now 6 weeks later Adsense confirmed that it was in fact a penalty and we lost the nessie arrows. They asked us to remove a 300x600 Banner (3 years no problem on same design) which was close to Arrows, which we did. CTR is not coming back though, and the Adsense team is unresponsive.
My question is, what would you do now ? We are not a small website, last month we had around 10 Million Impressions, mostly from Asia. We always only monetized with adsense, but with the CTR gone this is not a profitable option anymore.
I am thinking of implementing DFP with ADX and maybe Header Bidding and other ad networks.
Do you have any ideas on what do in my situation? Im getting a bit desperate...
