I have 5 article directories I submit to. Once of theme doesn't allow HTML in the resouce box, so I am just forced to but the default url to my site (with no keyword anchor text) like so: Find more on this topic from my site, http://example.com. Is this worth it for backlink purposes? I never saw article directories (like ezine) to be there for traffic, I saw it more as just a place to get a backlink. Is this correct?
