I have just read a summary of a [tag]poll[/tag] for online marketers. It was rather interesting reading.
According to Netimperative:
“More than two thirds (69%) of [tag]marketing[/tag] professionals believe that better training and education methods are required for online marketing practices” and “Just 7% have so far utilised blogging within their online marketing activity.”
Read some of the survey results at Netimperative and you will get some insight into what marketing professional use.
