Structured data markup
It has been long time enough for developers and webmasters and so called seo experts to do some homework about structured data markup, have anybody here spotted any improvement on a website search rank after applying this structured data markup ? I mean like if you read a blog or a post or an article , or even had a personal experience with one of your websites , so we can get some review on the effect of using this markup in website vs not using it at all.
I have been reading and asking in google forums about certain technical things related to to avoid getting errors in google test tool , but until this moment i didn't get a direct answer on one simple question , what is the best practice for applying structured data markup on a FORUM software .
