Buttons for Posting to Social Media

We want to suggest a button in the backend for banner ads to be able to send our ads to our social media pages. We have customers that are currently requesting that their website ads be pushed out on social media for an upcharge. Creating these buttons would make this easy and efficient for us to do quickly instead of having to log into each individual account and post it. I know this is possible, because our classifieds at https://classifieds.douglas-budget.com/ allow us to share this when you click on one of the ads.
