Top test of 2014
We tested the effect of drawing attention to social proof & customer feedback on our top selling product - the result was a 30% increase in revenue from search and a 10% increase in overall revenue. Definitely the ammo I need to increase the amount of customer driven feedback on our website.
Also, what type of business do you have -- retail, etc.? I'm curious since some industries may be more impacted by social proof than others.
