How to clear Facebook Sharer cache?

Question

We used the link:

http://www.facebook.com/sharer.php?u=[shared URL]

...to share a particular page. However, Facebook Sharer uses the cache

Answer 1

I just posted a simple solution that takes 5 seconds here on a related post here - Facebook debugger: Clear whole site cache

short answer... change your permalinks on a worpdress site in the permalinks settings to a custom one. I just added an underscore.
/_%postname%/
then facebook scrapes them all as new urls, new posts.

Answer 2

Append a ?v=random_string to the url. If you are using this idea with Facebook share, make sure that the og:url param in the response matches the url you are sharing. This will work with google plus too.

For Facebook, you can also force recrawl by making a post request to https://graph.facebook.com

{id: url,
scrape: true}

Answer 3

If you used managed wordpress or caching plugins, you have to CLEAR YOUR CACHE before the facebook debugger tool can fetch new info!

I've been pulling my hair out for weeks figuring out why changes I made wouldn't show up in facebook debugger for 24 hours!!!! The fix is I have to go into my wordpress dashboard, click the godaddy icon on the top, and click "flush cache." I think many managed wordpress hosters have a cache to figure out how to clear it and you'll be golden.

Answer 4

The page to do this is at https://developers.facebook.com/tools/debug/ and has changed slightly since some of the other answers.

Paste your URL in there and hit "Debug". Then hit the "Fetch new scrape information" button under the URL text field and you should be all set. It'll pull the fresh meta tags from your page, but they'll still cache so keep in mind you'll need to do this whenever you change them. This is really critical if you are playing with the meta tags to get FB Shared URLs to format the way you want them to inside of facebook.

Answer 5

I thing these two links have a wide discussion on your problem related stuff. fb:ref clear cashes by calling

fbml.refreshRefUrl

like this

<tt>fbml.refreshRefUrl("http://www.mysite.com/someurl.php")

You can study the related stuff from here fb:ref. I hope it will work for you

Answer 6

if you are using wordpress with a cache plugin, make sure you clear all your caches. Also make sure the image you are using has the recommended facebook size: 1200(w) x 630(h) or 600 x 315.
