Micro-advertising experiment, day 13

A very odd up and down pattern is emerging in the data: up down up down and over again; people must have been really at loose ends Monday for such a high percentage to come through. Thursday was not much of a day for the ad, only four clickthroughs out of 410 views for a 0.98% CTR. The total now is 62 views from 4,340 views for a 1.43% cumulative CTR. The ad buy must be close to the end, with only 660 left, about two days. Overall site traffic seems to be up since passing 4,000 on Dec. 5, with about 900 visitors in the past three weeks.
