I put in about 70 keywords to YSM last week, and was able to achieve 3rd-4th place with an overall bid of $0.76, over the weekend I noticed I didnt' get any additional impressions and check the bid levels and now it seems I need to bid at least $4-5 to even remotely be where I was in position before. WTF is this? How can it increase 5-7X in a span of days? This isn't a new niche and I doubt a rat race occurred in the last few days to promote it either. Anyone have any experience with this? Even at $0.76 I was barely making a profit with my campaign, and at these new levels I don't know how anyone out there is making money. FYI, I'm using direct linking with YSM, dunno if that has any effect. Any help or insight is appreciated. Thanks in advance.
