And initially I followed their advice without questioning
But I got a course by Perry Marshall [Click here to get the free course] and one thing he says over and over again is Test, Test and Test again.
So i decided to test two formats on one of my high traffic sites
I tested the 300 x 250 format within my content against the 160x600 skyscraper on the left side of my page
And the skyscraper format consistently did better than the 300 x 250 format
hmmm, i hear you say.
Goes to show that although the general guides are useful, different site will get different results
So get testing
