I have setup 10 niche sites with wordpress and amazon affiliate. I now need them getting traffic, is dofollow blog comments the best way? How many will i need per site before i get sales and traffic? Please advise me, thanks.
Have you pinged them? Use pingler.com. Social Bookmarked. I use onlywire.com. Write articles. With 10 sites that's going to be a lot of articles. Blog commenting can help in the short term and for backlinks. Be sure to relevant to the discussion and have something to offer. As far as traffic and getting sales, it depends on the niches and your sales technique. Both of which are unknown at this point.
