According to the data, online ads generate £1.89 of revenue for every £1 spent, compared to £1.80 for every pound spent on press, £1.60 for every pound spent on outdoor ads and £1.59 for every pound spent on TV. While online is obviously the way forward, there is strong evidence to show that outdoor and press coverage increases footfall to online, with online ROI hitting 82% as a result of increased outdoor ads.
