Stas Romanov reviewedShareKit.ioThe easiest way to customize Facebook link previews
 RecommendedPros: 

It is able to change the covers and text for links in social networks

Cons: 

There is only one drawback - it gives a separate link, such as a bit ly, so in the preview you can see a link with their domain.

This is a cool service. I tried at work.

Thanks so much for giving it a try, Stas! Just FYI, our "agency"-plan allows you to use your own domain with ShareKit (e.g. links.yourdomain.com) so that your domain shows up in the link preview

Does ShareKit have the permission of Facebook to enable the link preview / customization functionality? It seems like a great product, but the $99 per month charge seems a bit steep for a small agency and I'm concerned that as soon as I pay for the subscription, Facebook will shut you down? Please advise.
