The online world is becoming dominated by blogs; at least it seems like it. For a website owner, you may wonder if backlinks from blogs actually help in your overall search engine optimization strategies.
There are two ways to look at this question. Are blogs simply valueless sites that contain little in the way of value, or are blogs just an extension of a website and contain valuable content. The reality is somewhere in between I am sure. However, when it comes to SEO considerations, if a blog ranks well for a particular keyword then the value of any link is little different to a standard web page (if that exists anymore?).
Google indexes a lot of blogs, do they place high importance on them in the current algorithm? Probably no higher than any other page. However sidebar or blogRoll links and blog posts which lead to relevant content can be of high value. Almost every section of Google has a blog, often in several different languages.
Google could hardly consider Blogs as useless since they use them to broadcast new information. In fact many search engine marketing operators watch these Google blogs for hints to changes in the way Google ranks pages. Yahoo! also likes blogs, but not to the extent as Google. Like Google, Yahoo! uses a blog to make announcements.
Blogs often offer value as they are generally written by related industry bloggers. Blog links should not be discounted and should be a part of every SEO campaign. As with any website, treat each blog on its merits, there are good and bad websites, there are good and bad blogs. Obtaining a link from a well ranked blog can offer real value to your SEO link building strategy.
