If you use doc sharing sites for seo, how powerful do you think this is for link juice compared to say wiki's , blog commenting, web 2's etc Second question - do you blast one doc to loads of sites or make unique article for each doc sharing site? Third question - lets say you set up an account with (amongst others) scribd and submit a document -when you want to promote another site do you use the same login or do you set up a new account? Fourth question - do you use unique content? Fifth question - do you format the text with headings, bold italic etc and how many words do you think is ideal Sixth question - how many documents at each doc sharing site do you link back to your site? That'll do for now Thanks! PS Ideally these questions are aimed at people who actually use this technique!
