I’m looking to share things on google plus but I need to be able to populate the snippet info myself as the pages I am sharing are loaded via ajax on my jquery mobile site.
So that being said I need to set the info either via the url (facebook sharer style) or via javascript.
I was able to just go ahead and use the schema.org in my situation. This worked because when you view one of my pages is “promoted” to the first page in the list of cached pages. So even if you were to start on page A and browse to page B and then share page B when google searched the url you have provided page B is now before page A and thus is schema.org meta data is used.
I have no doubts that writing your own redirect page and passing it some thing like this
would work. The only thing to remember is that you will need to use a javascript redirect that way when google looks at the page it see’s the page and does not get redirected (bots dont use js) but when a person hits the page it will redirect them to the real page.
