Has anybody else using PW noticed that the bids as a whole seem to run in spurts of extreme expense, then long periods of being cheap?
For instance, today, seemingly every PW ad box in existence seems to have exploded in cost; I see some up 400-500%. I tried to start a campaign today, and quickly killed it after an hour of running four cents per click. Why does it get so expensive all of a sudden?
I think the reason why this happens is the introduction of two very large "campaigns" at the exact same time. I notice that many, many PW spots right now are occupied by an Evangelion ad. However, a single large advertiser couldn't do that--it would take two in a bidding war for each spot. So I think what drives these occasional spurts of expense are two (foolish) advertisers carelessly dumping massive amounts of money into the system and just setting it to "go".
In any case, for people who use PW as sellers, rejoice in a bit of extra income--and those who use it as buyers, wait until the fury cools a bit before you start advertising again. ^^ Thoughts?
