Have you, has anyone, graphed their CTR over the past few years to see?

Numbers like that might not mean much unless nothing has changed on a site/page over the years.

For instance, my CTR has taken a real dive this year, especially this fall. Looks really bad at first glance.

BUT.... I've added other ads to the site and when I figure in the CTR from those ads, things look pretty much stable.
