If you want your website to rank with the Facebook Search Engine it's a good idea to use OG tags or
Open Graph ProtocolSupposedly this is only to get better rankings with the FB SE, but I've found it helps tremendously with Bing and Yahoo...Google not so much.
Here is an example I always include in my <head></head> section.
<meta property="og:type" content="We have the best apples in town."/>
(this can be any description of your website) <meta property="og:url" content="
http://yourwebsite.com/"/>
<meta property="og:image" content="
http://yourwebsite.com/storefront/view/default_html5/image/hollisterlogo.png"/>
(any image in your directory will work here)There are several other OG properties that can be used, I have not yet experimented with them.
<meta property> will validate in HTML4 Validator if you use the XHTML+RDFa dropdown.
Presently it will NOT validate with the HTML5 validator, but then HTML5 is not finalized yet. In fact, the HTML5 validator is still experimental and at present does not support the RDFa suffix.
So if you need to validate your cart for a customer via one of the w3c validators it won't validate. You have the option of explaining that to your customer or leaving it out.
The issue is the term <meta property> instead of <meta name> . <meta property> is not valid HTML, but we all know Facebook rows their boat the way the see fit!
What? You didn't know FB had a Search Engine! If you're using FB social media buttons on your website, you want to be known to them! Every time someone hits the like button on your website the FB SE bot visits your website 3 to 5 times!
