A couple of great tools that I have used recently are the Facebook Debugger and the LinkedIn Debugger. Have you ever posted a link to either Facebook or LinkedIn and the post preview doesn’t look like the page? If this is something you have experienced, the likely cause is that the web page has been updated since it was published.
Depending to which Social Media platform you are using, to ensure that the post preview is current, use either of the tools above. To access the tools, google either Facebook Debugger or LinkedIn Debugger and look for the following websites:
Post your link into the boxes at the top of the page, then for Facebook click “Debug” and Linkedin click “Inspect”, both of these actions will “refresh” the link to ensure that the information pulled through in the post is up to date. If you have made any changes to one of your own web pages or blogs that have been previously posted, then the same applies.
