When you are sharing a message with links to your website on social networks you want to make sure that everything will be shared properly and that the message will look good.
Here are links you can use to check your URLs for various social networks.
For Twitter, the link is https://cards-dev.twitter.com/validator
For Facebook, the link is https://developers.facebook.com/tools/debug/
For LinkedIn, the link is https://www.linkedin.com/post-inspector/inspect/url of your site
However, if you use Social Web Suite you can see the live preview of all your messages directly on the dashboard.
