the difference between the free and commercial version of Sitelinkx is the following:
If you purchase the commercial version, you have these advantages over the free version:
You get commercial support via our ticket system instead of only forum support where a answer cannot be guaranteed.
You get the improved (commercial) version of Sitelinkx. The commercial version allows better options such as multi keywords, disabling the keyword(s) in specific articles/menu items, etc.
You get both Sitelinkx plugins : content and system . The content plugin replaces keywords in the content only, whereas the system plugin can replace keywords anywhere - even if you add your keywords in the template file. (Please note: only one Sitelinkx plugin should be activated at a time, either the content or the system plugin)
