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

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

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

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

This answer is intended for developers   Clearing the cache means that new shares of this webpage will show the new content which is provided in the OG tags  But only if the URL that you are working on has less than 50 interactions  likes   shares   It will also not affect old links to this webpage which have already been posted on Facebook  Only when sharing the URL on Facebook again will the way that Facebook shows the link be updated   catandmouse s answer is correct but you can also make Facebook clear the OG  OpenGraph  cache by sending a post request to graph facebook com  works for both http and https as of the writing of this answer   You do not need an access token   A post request to graph facebook com may look as follows   POST   HTTP 1 1 Content-Type  application x-www-form-urlencoded Host  graph facebook com Content-Length  63 Accept-Encoding  gzip User-Agent  Mojolicious  Perl   id  lt url encoded url gt  amp scrape true   In Perl  you can use the following code where the library Mojo  UserAgent is used to send and receive HTTP requests   sub  clear og cache on facebook       my  fburl        http   graph facebook com       my  ua          Mojo  UserAgent- gt new      my  clearurl     lt the url you want Facebook to forget gt       my  post body    id   gt   clearurl  scrape   gt   true        my  res          ua- gt post  fburl   gt  form   gt   post body - gt res      my  code         res- gt code      unless   code eq  200             Log- gt warn  Clearing cached OG data for  clearurl failed with code  code                         Sending this post request through the terminal can be done with the following command   curl -F id   lt URL gt   -F scrape true graph facebook com

Facebook treats each url as unique and caches the page based on that url  so if you want to share the latest url the simplest solution is to add a query string with the url being shared  In simple words just add  v 1 at the end of the url  Any number can be used in place of 1    Hat tip  Umair Jabbar
