In addition, if you’re using a URL manager such as sh404SEF®, your database of URLs could get huge, thus affecting the performance of your web site.
In previous versions of JCal Pro®, we added the nofollow HTML attribute to the date URLs to prevent search engines from giving them weight. This helped with the SEO problem, but the problem of multiple URLs created with no events remained. This was exacerbated on pages with a Mini-calendar module.
Todays official release of JCal Pro® 2.2.5 is designed to minimize these problems as days without events no longer generate URLs on the main calendar or in the mini-calendar.
JCal Pro® 2.2.5 is available on the JCal Pro® downloads page and all users are encouraged to upgrade to this version, especially if they are using an SEF extension.
