|sh404sef plugin for Zoo 2.2: Besides the usual SEF rewriting it allows you to remove/rename hardcoded keywords like category, item and frontpage etc. Please check the demo on my site to see how the URLs look like exactly. Why did I choose to mark the plugin as “commercial” here, even though it is free of charge? I decided to try the “advertisement based model”. I hope that ads on this site are relevant enough so that many users are interested to click. Maybe one day I make the site subscription based.
