We believe that optimized weblogs, also known as blogs, can increase the number of relevent backlinks to your website while at the same time directly increasing the amount of traffic to your website generally.
Blogs are generally well liked by the search engines largely due to the fact that they known to be updated with fresh content more regularly than static websites, broadly speaking.
One reason that blogging is helpful is that the blogosphere is relatively small compared to the greater world wide web, and therefore traffic opportunities are that much greater.
Blogs are often picked up independently and subscribed to by readers who are thirsty for news content.
Blogging is relatively new to the world wide web compared to other applications. Therefore the chance that your competition is doing the same thing is more minimal, comparitively speaking.
