Article Directories are OUT for Link Building (and have been) – or are they?
Over time article directories have gotten a little bit of a worse name. So just refresh everybody’s memory, an article directory is basically where you write 3-, 4-, 500 words of content and then you’ll include a little bio or some information about you at the bottom of the article, and you might have three links with keyword rich anchor text at the bottom of that article. And then you’d submit that to a bunch of what are known as article directories, and then anyone can download them or perhaps pay to download them, and they’ll use them on their own website.
