Blogs and Google PageRank - Why do Blogs have Such High Google PageRank?
(Page 2 of 5 )
Blogs tend to have very strong Google PageRanks. These high PageRanks are achieved through one of the hallmarks of the blogging technique. People who maintain blogs (called bloggers) are free and generous linkers. If gaining link exchanges was ever a problem for you in the past, you need to consider a starting a blog.
Incoming links are the determinant of PageRank. That is the strength of blogs. They attract both theme-based link exchanges and natural links from other blogs. There are also a number of special blog-only directories that supply an additional PageRank boost. That extra set of directories is not available to traditional websites unless they add a blog component. Blogs are also well represented in the important mainstream web directories, including The Open Directory Project and by extension the Google Directory, and the Yahoo! Directory as well. (For more on directories, see Hurlbert's article Blogs and Internet Directories: The Same and Different.
Blogs attract links because of several important factors. One of those factors is fresh, constantly updated content. It’s an old adage already that good content will attract links. With blogs, it is a fact. By providing your readers with quality daily posts, other bloggers will link to them, and comment upon them in their own blogs.
That linking achieves two goals. First of all, it adds a strong natural link. Secondly, due to the discussion of your blog post, in the linking blog, your incoming link is quite possibly themed. Because the linking blog is probably in the same general topic area as your blog, the theme is consistent. If it’s not a related blog, the context of the linking post itself can help to theme the link. In either case, your blog benefits from a solid boost in PageRank.
Bloggers are generous linkers to other blogs they enjoy and posts they believe will be of interest to their readers. Google PageRank is an issue for very few bloggers. There is little concern in the blogging community (sometimes referred to as the “blogosphere”) about hoarding PageRank. It is simply not on the radar of a huge percentage of bloggers. Because of that lack of concern, some very highly PageRanked blogs will freely exchange links, or link to another blog, with a much lower PageRank.
