Blog metrics are a way to measure the success (or at least the popularity) of a blog. In this article I will introduce you to several of the sites that are most popular for determining a blog’s success: Google PageRank, Technorati, Digg, and Alexa. Whether you put any stock into them is your call. (wink)
What is Google PageRank?
PageRank is the measure of the importance of a page based on the incoming links from other pages. In simple terms, each link to a page on your site from another site adds to your site’s PageRank. Not all links are equal: Google works hard to improve the user experience by identifying spam links and other practices that negatively impact search results. The best types of links are those that are given based on the quality of your content.
In other words, it’s about the incoming links. However, if Aunt Laurie is linking to you it’s nice but it doesn’t count as much as it would if ProBlogger were linking to you.
Are you curious about your own Google PageRank? You can find your own PageRank without installing the toolbar. The higher the number, the more popular the site.
What is Technorati?
The leading blog search engine, Technorati.com indexes millions of blog posts in real time and surfaces them in seconds. . .Technorati.com tracks not only the authority and influence of blogs, but also the most comprehensive and current index of who and what is most popular in the Blogosphere.
