I just did a presentation and, while preparing it, I came upon this incredible statistic about web marketing
. They sent out a bot, apparently, looking for known advertising network code and found that only 20% of the sites had any of the 100 plus companies' code on the sites. Of those 20%, Google had the vast majority but what struck me was how all these top rung companies (Google, Yahoo, Microsoft etc) could only entice 20% of the sites to install code and earn money? Why so pitiful a participation rate by website owners?
