Some webmasters know that blog advertising is becoming very popular. In fact, when I noticed this new idea, I didn't think of creating a blog for this purpose. I didn't think of trying it either.

After seeing several other blogs doing the reviews, I have decided to join the club. Of course, the main reason is that this is still new and not too competitive yet.

A good benefit for advertisers is that their links will be within content. Such links look more natural in the eyes of SEs as you know. It seems that link exchange and other rather old SEO techniques are really not effective any more. That's why people started to purchase text links, hoping one way links would be more valuable and pass PR points better.

Article directories function the same as this blog ad basically, except listed links are often buried in deeper pages. Free service, most of them are, so it's not bad at all. But then that niche is also saturated these days.

So, let's see how this trend will go. Site review blogs will do well, I think. I am sure you would agree with me since you are reading this :)
