For several weeks, the bounce rate at 40Tech has been in the low single digits.  According to Wikipedia, bounce rate "essentially represents the percentage of initial visitors to a site who 'bounce' away to a different site, rather than continue on to other pages within the same site.  The formula used to calculate bounce rate is: Bounce Rate = Total Number of Visits Viewing One Page ÷ Total Number of Visit."

Yesterday and today, though, the bounce rate at 40Tech shot up dramatically.  That left me scratching my head until I realized that when I had upgraded my theme to a new version, I had forgotten to carry over the code for Yet Another Related Posts Plugin (YARPP), a WordPress Plugin.  YARRP "gives you a list of posts and/or pages related to the current entry, introducing the reader to other relevant content on your site."  You can see it in action at the end of any post on 40Tech.

Most sites that I visit already use YARPP, or something similar to it.  If you don't use it, go get it.
