I was recently asked to help someone define success metrics for a corporate blog. I thought this was such a great topic that I'd share my answer with a wider audience. Many of the success metrics for blogs are similar to those that might apply to a Website, since blogs are a variation on a Website. These 'shared' success metrics include: Blog/Website Traffic * Unique Visitors * Unique Visits * Repeat Visits * Page Views * Page Views per Visit * Average Time Spent on site Blog/Website Brand/Content Interactions * Content Page Views * Content % of Page Views Blog/Website Responses (if applicable) * Number of Desired Responses * Conversion Rate from site visitor to Desired Response * Cost-Per-Desired Response In addition to the above 'shared' success metrics, there are a number of success metrics that are specific to the unique nature of blogs. These blog-specific success metrics include: * Number of Subscribers to the blog's RSS Feed * Number of Overall Inbound Links to the blog * Number of other Blogs that Link to the blog * Number of Comments Submitted to the blog * Number of Trackbacks Submitted to our blog Not all of these success metrics will apply in every case, however these are some of the more common ones.
