[pmwiki-users] Added meta tags and schema.org microdata injection into pages

Sat Sep 24 14:09:51 CDT 2011

The advent of Google +1 triggered my attention to some (probably)
useful pieces of information that could be added to our html pages in
order not only to let the +1 button (and its Facebook cousin) work
better, but also (supposedly) to generally achieve better display in
Google (and potentially other search engines) results.
A few examples of such things might be similar to these:
   <html itemscope itemtype="http://schema.org/Article">
   <meta itemprop="name" content="..." />
   <meta itemprop="description" content="..." />
   <meta itemprop="image" content="..." />
   <meta property="og:title" content="..."/>
   <meta property="og:image" content="..."/>
   <meta property="og:description" content="..."/>
but there there is a bit more here
http://developers.google.com/+/plugins/+1button/#plus-snippet

Does the community think that such pieces of added information might
really make a difference in search results and social sharing?
I personally do, definitely.

If so, what would/will/is the practical way to place/inject such kind
of things into the html, per page?
I just know about standard "keywords" and "description" meta tags, but
here things seem to go a little further, and slightly more convoluted.

Thank you
