OpenGraph or Schema.org?

Question

Just wondering whether you guys out there are favouring the OpenGraph protocol following markup like:

Answer 1

So, to start with a couple of cliche's and mangled metaphors - we're talking apples and oranges a bit comparing OG and Schema.org, and when it comes to this metadata it's horses for courses.

The right answer depends on your intent, in adding metadata to your page. What is it that you're hoping to gain? What is the win for you here? The different forms of metadata are for slightly different purposes.

Google has made it clear that it's moving away from a focus on microformats and onto a focus on Schema.org in order to build rich-data results for search. If you want to optimize for Google, Bing and other search engines add the Schema.org markup. It's the direction HTML5 has stepped in.

Facebook OG markup is to be added if what you want is to benefit from turning your content into a social object and enable its multi-point connectivity to the social graph that is the Facebook universe.

In my experience most people are looking to gain from both approaches - do as well as they can in search rankings and increase reach and distribution through social channels. So, IMHO, it's probably best to be as thorough as possible adding the Schema.org markup where it fits your content and use Open Graph metadata. They do slightly different, but complementary things.

Answer 2

All depends if you're trying to markup your website for a social world (facebook) or search engines. Both are recommended but if you only have time for one then prioritize the company's marketing focus. OGP is huge for facebook, but does not have an ounce of use in SEO. Seo is completely reliant on micro-data and is the way for proper html5 creation.

Update

For anyone finding this answer, a lot has changed since I first posted it. Schema.org is widely used by all major search engines and then some but the markup is now preferred to JSON-LD. Great article from SEO Skeptic outlining the change made by Google.

Google Structured Data provides documentation in JSON-LD and is greatly encouraged although RDFa and microdata is still partial supported.

JSON-LD should be used in conjunction with any social channels you are trying to target OGP for Facebook, Twitter Cards for Twitter, etc
