Thanks I appreciate the response. I'm definitely looking at as a long term strategy to build authority. Do you see any downside to submitting to all three sites? Obviously creating duplicate content but seems to me it should fall into the same category as video sites where the dup content doesn't really hurt you. I don't know if that is the case so would like to hear from those that have more experience submitting to the document sharing sites.
If there are issues with dup content is it best to pick one site and build up a channel or mix up your submissions across all three. Thanks
