Well, I expect this to be MY last post to this epic thread, at the risk of returning to the original topic of this thread. As you may recall, I was one of the early reporters of pathetic PPC and CPM. Around Feb 2 the decline in PPC started, and eventually bottomed out at around 42% off Jan AVERAGES around the center of this month. Well what a roller coaster this has been. Beginning last weekend and strengthening to the point of a real recognizable trend THIS weekend and this Monday morning we are now back to about 95% of our prior Jan PPC, and CPM and CTR are at new all time highs! Based on 1/3 day of data I'm anticipating an all time high earnings day.
Some continue to insist this is just a "natural" advertiser/rates/randomly driven phenomena. I find the sharpness of the changes, the simultaneous changes in CTR and PPC and the fact that the large moves consistently seem to start on Friday or Saturday hard to construe as a "random event". I still feel that what we have seen is the result of a, probably still ongoing, set of manual adjustments and/or experiments in algorithm changes by G whose most apparent results were to cause wide fluctuations in stats. A benefit, at least to me, seems to be a massive reduction in traffic sucking (scraper) and affiliate ads.
We prviously had over 180 URLs filtered. We are now down to about a dozen and none of the old off topic and cr@ppy ads have returned yet. This algo change seems to have acted like revving a car engine that had been abused or sitting too long to "blow out" the buildup of deposits. I just hope next time they decide to do it, it doesn't impact our earnings as drastically.
