Update Facebook Open Graph meta tag through JavaScript

Question

I\'m trying to update the meta content of the Facebook\'s Open Graph title. I updated the content, but when it published the feed, it\'s still pulling the old information. <

Answer 1

Facebook scrapes pages for meta-data only when it is necessary. After you make changes to the metadata, you need to resubmit the object with the 'scrape' parameter set to 'true' in your POST request.

This is outlined in the Open Graph documentation for updating objects.
