I just read about a great tool, PostRank Analytics (https://
analytics.postrank.com/), which uses your Google Analytics data to
tell you how much traffic and how engaging a blog post gets. It cost
$9 per month and is still in its Beta stage but could be a good choice
for anyone who is using their blog and a marketing tool.
I set up and account for myself and Jay Baer recommends it (http://
www.convinceandconvert.com/web-site-analytics-and-metrics/finally-a-blog-post-scoreboard/)
in his blog. I'll keep you posted on how useful it is. Feel free to
post your thoughts and experiences...
