Open Graph Meta Tags Implemented

How long before FB stops using Meta Description when Sharing page

[jbnz]

I've just added Open Graph meta tags to a site.

However when a page is shared to a user's timeline, the standard meta tags are displayed in the Share dialog.

How long does it take for the Open Graph meta tags to be used instead?

Cheers

Go to https://developers.facebook.com/tools/debug/ [developers.facebook.com] , enter the site URL and click "debug". Click "show existing scrape information"" Facebook will show what's currently in their cache. Likely it was a result of a previous share.

You can ask it to "fetch new scrape information" to update the facebook cache. It should then match your current site.

That's great for one page at a time. However I want FB to re-scrape multiple pages (100s)

Is there a way to bulk re-submit pages to FB for re-scraping?
