Really? Sunday was my worst day since (well, I don't even care to look) but it wasn't due to overall CTR believe it or not. It was due to the fact that ALL my clicks were on LINK UNITS with not a single click on any other type of ad unit (and I used text ads exclusively). Was getting pennies per click on the Link Units BTW. Had a similar situation yesterday, just a couple of ad unit clicks and all the rest were clicks on link units. The difference, great CPC on the link units so a good day overall. People aren't clicking on the text ads in the numbers they once were. Some color changes helped a bit yesterday I'm thinking but it's still a mess in my opinion. Would love the previous poster to be right (especially if it corrected itself) but I'm sticking with what I can see right in front of my face for now (or at least until I wake up).
