So I've had steady $300-400 days all week. Yesterday was only $230 which was no biggie..but today I'm at $3.25. My test e-mails display fine/the images work. Delivery is normal. However I'm at 185 clicks all day (low) and no conversions. My AM says my referring URLs are showing up as search links (which sounds like they're dead) Plus all day for absolutely nothing to convert is really bad/out of character. Though my tests to myself show that my links/images work. I'm completely baffled. Any ideas?
