Blogs have become world famous because of their working mechanisms. The posts added to the portals get published extremely fast over the net, accessed by search engines like Google on a constant basis and being easy to reach by net surfers. Today, it is useful to install new blogging systems on websites and using them to publish fresh contents on the net and through RSS systems, the materials could appear on tens of other directories, leading to gaining one-way votes at the same time.
In some highly competitive niches, blogs are found at the top pages of search engines like Google. Of course it would be a mistake to assume as soon as blogs are launched, they would be found on front pages of Google for the targeted keywords because they still need proper optimization and promotions including one-way links, coming from sources related to their niches. A great blog is the one which is powered by unique contents, at the same time having so many incoming links.
