You may want to proceed with caution when utilizing some of the standard online SEO tools and reading some of the forums on how to increase your site's rank, authority and backlinks… some of this information is far outdated.
Case in point, I read on quite a few sites that submitting your site to Yahoo!'s directory was a great idea. For $299, your site would get indexed within the Yahoo! business directories, promoted on Yahoo's directory page for a day, and perhaps get some attention from other sites that see Yahoo! as an authority.
If you think that slow rising green bar is representative of the rise in traffic I received for the purchase… you're wrong. That was traffic before I registered the site with Yahoo! It's been dropping in Yahoo! search traffic ever since.
Perhaps people really don't see Yahoo! as an authority anymore (some sarcasm there… I honestly expected a little bit of traffic). Sadly, my organic traffic from Yahoo!'s search engine is in a steady decline… but thankfully (lots of sarcasm here), 17 visitors came to my site from the Yahoo directories in the last 60 days. If that keeps up, that will be about 100 new visitors that will come to my blog in the next year – at a cost of about $3 each.
