Looking through our AdWords report  for our Code Generation 2007 ad campaign earlier today I spotted this rather unusual occurrence:

If you don’t use AdWords or aren’t familiar with online advertising the columns are:

1. Number of Clicks on an advert
2. Number of Impressions (times the advert was shown) and
3. Click-Through Rate (What percentage of times the ad was shown and clicked on).

We usually expect CTRs of around 1% for search advertising but as you can see this particular ad seems to have made a stronger impression (pun intended).
