On RT's SEO page,
www.rockettheme.com/docs/technical_tips/blogging/seo.md
, it indicates to set the Add Suffix to URL to 'Yes'. Has there been any definitive research that supports adding the suffix versus not adding the suffix? I have done a lot of reading and it all seems subjective with little supporting evidence either way.
It doesn't say to set it to 'Yes' anywhere on that page... it merely lists the options available in Joomla...
I personally don't think it matters... I prefer it without....
I do a fair amount of SEO... and yes, everyone has an opinion
My gut tells me Google doesn't penalize/reward either way... but that if Google's stated mission is to provide users the best possible/friendliest result then having NO suffix is a "friendlier" URL...
