I have used these tags before to share some content for user to preview on facebook or twitter before they actually go into the shared link/video. But when I was asked to include these tags only for SEO I had this doubt which I can split into two parts
Let us assume these tags are included in the head tag of HTML doc. But there are no like, tweet or share links in the page.
a) Will these tags then help google to search this page (assuming the page already has title and description meta tag)?
b) Will these tags help search used within facebook and twitter?
Let us assume these tags are included in the head tag of HTML doc and also there are like or share links in the page.
c) Will these tags then help google, facebook and twitter to search this page since there will be lot of clicks happening through these like, tweet and share links.
