As far as I see these buttons also appear on my page. How do I make these button appear only in single post page and not in any other pages?

These particular 2 (I only use these 2 and Facebook myself) pull the header image to the share.  Does Sharexy create meta tags?

I can see the first website I signed up with listed in the 'Analytics & Earnings stats' page but how can I add another?

This is probably one of the nicest looking social share bars I've found for wordpress. But it needs an "I'll add it manually" option, like a template tag I can insert on specific pages / templates that I want it to display on. I'm designing a shop for a glass artist (www.untamedrose.com) social sharing is important for this kind of client, but there's really no way to control where the bar shows up. For instance, I need it to show up on pages because there are certain pages she wants it on ... But I don't want it on the check out page.... or the home page.
