Good post by Brian Carter at the Search Engine Journal blog on why “Your adwords ROI is better than you think“. He highlights that the date range you choose when reporting on Adwords conversions could make a big difference to the % conversion rates you see i.e. you could get an inaccurate view of how your campaigns are performing. I picked this post up from one of the best sources of marketing information, the “Who’s blogging what” weekly newsletter.
