Facebook Open Graph not clearing cache

Question

I m having troubles with my meta tags with Open Graph  It seems as though Facebook is caching old values of my meta tags  Old values for Attributes og title and og url are still used  even though I have changed them already   I ran Lint on a page in my site  and this appeared     Notice that there are two values for og title and og url  and the last one prevailed  However  The last two entries are the OLD entries that I used for this site  I am now currently using these meta tags  you can verify if you view the source of the HTML     lt meta property  og title  content  Smart og rummelig pusletaske fra Petit Amour med god plads til alt  amp  8211  v  rdi 1 099 kr  amp  8211  k  b nu kun 599 kr      gt   lt meta property  og description  content  Pinq dk - Det gode liv for det halve   gt   lt meta property  og type  content  product   gt   lt meta property  og url  content  http   pinq dk tilbud landsdaekkende lissy    gt   lt meta property  og image  content  http   pinq dk wp-content themes pinq images logo-top png   gt   lt meta property  og site name  content  Pinq    gt   lt meta property  fb app id  content  161840830532004    gt    Why is Facebook caching og title and og url  Is anyone experiencing the same issue

I ve found out that if your image is 72dpi it will give you the image size error  Use 96dpi instead  Hope this helps

I had a different  but similar problem with Facebook recently  and found that the scraper debug page mentioned  simply does not appear to read any page in its entirety   My meta properties for Open Graph were further down in the head section  and the scraper would constantly inform me that the image specification was not correct  and would use a cached version regardless   I moved the Open Graph tags further up in the code  near the very top of the page  and then everything worked perfectly  every time

Really easy solve  Tested and working  You just need to generate a new url when you update your meta tags  It s as simple as adding a   amp cacheBuster 1  to your url  If you change the meta tags  just increment the   amp cacheBuster 2    Orginal URL  www example com   URL when og meta tags are updated   www example com cacheBuster 1   URL when og meta tags are updated again   www example com cacheBuster 2   Facebook will treat each like a new url and get fresh meta data

Years later and this is still a common problem  but its not always facebook s cache  It is very often human error  allow me to elaborate   OG TYPE effects your image scrape    https   ogp me  type article not the same as https   ogp me  type website   Be aware that og type website will cause any  sub-pages  of that url to become  canonical   This means you will have trouble getting your images to update using the scraper no matter what you do    Consider this  assumption and common mistake    - lt meta property  og type  content  website    gt     https   www example org   parent   - lt meta property  og type  content  website    gt     https   www example org sub-page   - lt meta property  og type  content  website    gt     https   www example org sub-page child-2   - Ergo   sub-page  and  child-2  will inherit the og image of the parent  Those are not  all websites   1 is a website  the others are articles    If you do that Facebook will think all of those are canonical and it will put the FIRST og image into all of them   try it  you ll see  - if you set the og url to be your root or parent domain you ve told facebook they are all canonical   there is good reason for that  but its off topic    Consider this solution  which is what most people  really want    - lt meta property  og type  content  article    gt     https   www example org sub-page   - lt meta property  og type  content  article    gt     https   www example org sub-page child-2    If you do that now Facebook will give you far far less problems with scraping your NEW images   In closing  YES the cache busters  random vars  changing urls and suggestions here can work  but they will seem like  intermittent voodoo  if the og type is not specified correctly    PS  remember that a CDN or serverside cache will serve to Facebook s scraper even if you  think  you can see the most recent version   I wont spend any time on this other than to point out it will waste colossal amounts of your time if not double checked

Ooook  finally it helped  I use IP Board   What I had to do was    Change url of og image on my website  General configuration   Try this method with  fbrefresh 1154464gd56   Thanks to author for this thread   EDIT  What is more you need to remember about image requirements  For now  january 2013  it s   - at least 200 px in both directions  - maximum ratio 3 1

One thing to add  the url is case sensitive  Note that       apps facebook com HELLO   is different in the linter s eyes then      apps facebook com hello    Be sure to use the exact site url that was entered in the developer settings for the app  The linter will return the properties otherwise but will not refresh the cache

Had a similar experience  Website link was showing a 404 in the preview that facebook generated  Turns out the og url metadata was wrong  We had already fixed it a few days back but were still seeing a 404 on the preview  We used the tool at https   developers facebook com tools debug  and that forced the refresh  didn t have to append any parameters by the way  In our case  Facebook didn t refresh the cache after 24 hours but the tool helped force it

Yes  facebook automatically clears the cache every 24 hours  Actually facebook scrapes the pages and updates the cache every 24 hours https   developers facebook com docs reference plugins like  scraperinfo

User · Answer

Basically  the answer is patience     I checked the Linter this morning  and og title and og url displays correctly  without the redundant values  I guess FaceBook automatically clears its cache at some specific interval  I just have to wait

The most voted question is quite outdated   These are the only 2 options that should be used as of November 2014   For non developers   Use the FB Debugger  https   developers facebook com tools debug og object Paste the url you want to recache   Make sure you use the same url included on your og url tag  Click the Fetch Scrape information again Button   For Developers   Make a GET call programmatically to this URL  https   graph facebook com  id  YOUR URL HERE  amp scrape true  see  https   developers facebook com docs games payments takingpayments scraping  Make sure the og url tag included on the head on that page matches with the one you are passing  you can even parse the json response to get the number of shares of that URL    Additional Info About Updating Images   If the og image URL remains the same but the image has actually changed it won t be updated nor recached by Facebook scrapers even doing the above   even passing a  last update  TIMESTAMP  at the end of the image url didn t work for me   The only effective workaround for me has been to assign a new name to the image    Note regarding image or video updates on previously posted posts    When you call the debugger to scrap changes on your og tags of your page  all previous Facebook shares of that URL will still show the old image video  There is no way to update all previous posts and it s this way by design for security reasons  Otherwise  someone would be able to pretend that a user shared something that he she actually didn t

The OG thumbnail does not seem to refresh even if passing the fbrefresh variable  To update this without waiting for automated clearing you ll need to change the filename of the thumbnail associated meta tag value and refresh

User · Answer

It is a cache  ofc it refreshes  that s what cache is ment to do once in a while  So waiting will eventually work but sometimes you need to do that faster  Changing the filename works

I m sorry folks but the correct answer is   There is no fool proof way to update the open graph og image url with immediate result   It is cached until fb updates  reportedly every 24 hours   Here are things that have been reported to work by others but I have had ZERO success with any of them    Choosing  Fetch new scrape information  Changing the actual image filename and or deleting the original Adding a query string to the image url by appending a PHP TIMESTAMP or  anything Adding the     yoursite com  fbrefresh anything  query string to the debugger fetch url Choosing the graph API link at the bottom of the og dev page Choosing to see exactly what the scraper sees - does not appear to request real time un-cached scrape data  it still shows the cached image url even if the file no longer exists   Inspecting your code is always a spot on way to confirm it is not an issue with browser cache or some caching service   If the meta information is up to date in your code and you ve tried all of the above  unless another suggestion comes to fruition   the correct answer is you can do nothing but wait

I had the same problem with fb and twitter caching old meta data  this threw me for a curve as I continued to edit the code but no change  I finally discovered they had caching my first request  Adding a query string to the url worked for twitter but not fb for me

User · Answer

We just ran into this  as it turns out  we weren t linting the right url  since the real url had a query string  duh  different page as far as a bot is concerned    http   example com        http   example com  utm campaign foo  The linter will recache your page  you don t have to wait

If you have many pages and don t want to refresh them manually - you can do it automatically   Lets say you have user profile page with photo    url    http       SERVER  HTTP HOST        user profile   user photo    http       SERVER  HTTP HOST        user photo    lt meta property  og url  content   lt  php echo  url    gt    gt   lt meta property  og image  content   lt  php echo  user photo    gt     Just add this to your page      with jQuery   post       https   graph facebook com                 id    lt  php echo  url    gt            scrape  true            function response           console log response                with  vanilla  javascript var fbxhr   new XMLHttpRequest    fbxhr open  POST    https   graph facebook com   true   fbxhr setRequestHeader  Content-type    application x-www-form-urlencoded    fbxhr send  id  lt  php echo  url    gt  amp scrape true      This will refresh Facebook cache  If you use the jQuery solution  have a look at  response  in console log - you will find there  updated time  field and other useful information

I was having this issue too  The scraper shows the right information  but the share url was still populated with old data   The way I got around this was to use the feed method  instead of share  and then populate the data manually  which isn t exposed with the share method   Something like this   shareToFB        gt        window FB ui       method   feed       link   signup yourdomain com  referrer   this props subscriber sid        name   THIS WILL OVERRIDE OG TITLE TAG       description   THIS WILL OVERRIDE OG DESCRIPTION TAG       caption   THIS WILL OVERRIDE THE OG URL TAG

Go to http   developers facebook com tools debug Paste in the url of the page and click debug  If your site is using url aliases make sure you are using the same url as Facebook is using for the page you are sharing  example  in Drupal use the node   path instead of the alias if the page is shared via that url    Click in the  Share preview  part on  See this in the share dialog  link

I had the same issues using og image  several attempts to rename the file or clear FB cache did not work either via the facebook debugger or testing via an actual account   The new facebook guidelines state the image size should be 1200 x 630 or having that aspect ratio  this seems to be wrong  the only thing that worked for me was using an image with square dimensions   Edit   Afew hours I went back to use 1200 x 630 and it magically worked  it was magical   I also renamed the files to f   kfacebook jpg  not sure it helped but it felt good
