Facebook Meta Tags

When setting up social sharing, make sure that you modify all settings under Setup > SEO > Description.


The Description option should be set to your ideal sharing setting here. When the description is modified, make sure to hit Publish to update this on the site. 

Afterwards, go to the Facebook debugging tool, and make sure that after clicking Debug, you click the Scrape Again button, on the Time Scraped field.

Trust this helps.
