This 60% is based on the average over the last five years or so. It seems strange that it would drop like that suddenly as a result of advertisers pulling out, especially since this is a very summer/seasonal niche.
I get about 1000 uniques/day and 2000 page views, lots of long tail traffic and it's a very specific niche with good content.
Any ideas what else I might try to track this down? It just seems very odd to be that this would happen suddenly for no apparent reason. As far as I can tell, the ads showing are the same ones, but I have to admit I didn't really keep track.
I should also mention that I've been working on ranking and bringing traffic to this site, and my traffic is about double that of last summer. I don't know if that has anything to do with it, but it certainly makes it extra discouraging.
Any thoughts would be appreciated. Thanks.
