Back in July, I posted an entry about my use of Adwords to drive traffic to this site.
Here is the stats summary since August:
| Month | Clicks | Impressions | CTR |
| August | 239 | 278,701 | 0.086% |
| September | 299 | 324,611 | 0.093% |
| October | 178 | 217,258 | 0.082% |
| November to Date | 54 | 66,122 | 0.082% |
You can see that the number of impressions started dropping off in October. Based on where we are at this month, we’ll be lucky if we do half the number of impressions from October.
Since I started, 99+% of the impressions have been coming from content targeting ads. It seems that Google has decided that my ads don’t fit with some sites where they have been showing it. They must be changing algorithms to better match ads to page content.
Following that line of logic, I would think that the click-through rate would improve with better targeting of my ads. As you can see, the CTR is essentially the same over the time I have been advertising.
The argument could be made that the 54 people who came to the site this month are better qualified prospects and will become long term readers of the blog. No way to know.
I’d be interested in hearing others’ experiences.
