I have a directory and I really want it to have a high pr and backlinks. Will word cloud sites like www.the400links.com (PR6) help me get traffic and a higher pr?
Maybe temporarily, but not long term. Word cloud sites lose their juice pretty quickly. See this thread: Why Links From A Word Cloud Sites Are Worthless
You should expect ZERO direct traffic from that word cloud site, And little PR gained because there are too many links on that pages. Also because the sites listed are usually completely unrelated, Google could consider that as a farm link and your gained PR could be ZERO too.
Yes, that right. I do have my own word cloud and to be honest..i got zero traffic from that site. Much worst, the previous owner ( i buy this word cloud from here) had deleted that site.
They can help if you want to get the bots quick on your site but probably that's all they can do in terms of optimization.
i dont believe that word cloud sites will help anythink. they will not help your seo and traffic because of too many links on those web sites
