Add new meta tags to you Plone site, for better controlling how your items are shared on Facebook.
Table of contents
Are you commonly sharing contents from your Plone site or a site page to a Facebook account?
When you use the nice Facebook sharing interface, you have a simple way to customize additional data for the item that will be published (mainly: choose a proper image from the remote page). However when trying to do this automatically (e.g: you are publishing the link in a Twitter account that also feed a Facebook page) Facebook is choosing an image for you... and often this is not the image you want.
How can you solve this? In general you can provide some additional meta tag information using
Open Graph standard, customizing many aspect of the way of sharing contents on Facebook.
Installing collective.fbshare product and add some additional meta tags in the head section of your site.
When sharing the site root, you'll get:
og:type- Always
website og:url- The URL to the site
og:image- See next section
og:title- The name of the site
og:description- The description of the site
When sharing site content's you'll get:
og:type- Always
