I have placed these meta tags on a site I'm working on. I then have a 'share this page' type feature which content authors can override the default content which appears in the share window using the og tags which are working fine for Facebook, however Twitter is not working.
<meta property="og:image" content="test test test" />
<meta property="og:title" content="test title goes in here" />
Reading around a bit, I can see that it shows here
that the fall back is the og tags which I already have. I've also read about twitter cards however I don't think I'm using them as they describe - its just a share button? This post explains using different ones:
http://davidwalsh.name/twitter-cards
I'm wondering if anyone can shed any light on why the og tags may not work? Do you need to apply for something from Twitter??
Turns out I needed specific tags for Twitter and Facebook after all. The doco was out dated - would recommend reviewing new doco if you need to do this as it changes all the time..

I have a question that was initially asked here: Open graph og:video Meta Tags content in 2010, but the answer no longer works.
I'm trying to show a YouTube video in Facebook (and have it play inside Facebook) when a link is shared. The following og:video tag on the page doesn't work (it never really did):
<meta property="og:video" content="https://www.youtube.com/watch?v=ZH4YSF-i5dY" />
The solution proposed here https://stackoverflow.com/a/17811187/188740 in 2013 worked really well until recently. It was to change the og:video to something like this (notice the way the v query string value is represented):
<meta property="og:video" content="https://www.youtube.com/v/ZH4YSF-i5dY" />
That no longer works and Facebook completely ignores it.
Another option I tried is to put the YouTube URL in og:url:
<meta property="og:url" content="https://www.youtube.com/watch?v=ZH4YSF-i5dY" />
That approach instructs Facebook to scrape YouTube to get the thumbnail image, but clicking on the post sends the user to the original page that was shared. The click behavior is the right one (I want the user to go back to the originally shared page), but there's no way for the user to play the video.
Anyone know the solution to this problem?
Update:
Unfortunately, it's starting to look more and more like this is a change that Facebook made in August 2017 (and rolled out slowly across different regions over several months) and it's by design. In other words, there's no way to make this work. :-( If anyone has a workaround, it would be great for the community to know.

We are making use of the FB Like/Share functionality on various pages for our client's site(s). On each page we want shared, we add the following in the meta tags:
<head id="ctl00_Head1">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta http-equiv="Expires" content="0" />
<meta http-equiv="X-UA-Compatible" content="IE=8" />
<!-- social sharing metadata -->
<meta property="og:title" content="Our Site Title" />
<meta property="og:description" content="A description to be used in the share dialog." />
<meta property="og:image" content="http://us.oursite.com/images/FB_ShareThumbnail_US.png" />
<title>Our Page Title</title>
<!-- favicon -->
<!-- stylesheet and js links -->
<!-- inline js -->
</head>
In addition, we also display a Facebook graphic with the following HREF:
The client would like a standard Image, Title, Description used, regardless of the actual page\article shared (sort of "brand control"). We currently have our og: meta tags setup to render down the same data for each page/article.
When the users click the "share" functionality, they don't get a page/article picture, nor any good description or title (as i thought the tags were supposed to provide).
The pages currently being shared are accessible to anonymous users, so the FB bot can access the pages. The image specified in the og meta tag is also available to anonymous users. The first question is why does this method of sharing not seem to use the correct defaults for sharing??
The next question is, the next feature request is to have authenticated pages be able to be shared with the same default image, title, description. I was approaching this from a server perspective, where I'd look for the FB bot and redirect the bot to a "static" page that contains only the minimal markup needed to extract the image, title, description. I've proofed this and it works pretty well. I just feel like it might be a bit complicated. Wondering if there is a "better" or more "best-practive" way to share authenticated pages and have the share functionality know about our standard image, title, description??
Thanks In Advance!
Update:
I found this related Q/A on StackOverflow: Facebook Share doesn't show my description or my thumbnail
When I ask "Wondering if there is a "better" or more "best-practive" way to share authenticated pages and have the share functionality know about our standard image, title, description??", this is the type of thing I am talking about. If I can pass all data needed to the Facebook sharer.php via querystring parameters (and this results in no Facebook scraper action needed/taken), that is ideal, then I don't need to write any server side logic to re-route the Facebook scraper.
I tried taking the Url provided in the above noted Q/A, reformat with my data, but no luck. Wondering if this is documented somewhere on FB?
There can be a number of reasons why it isn't using the provided og meta data, but unless you share us the code/url we can just guess what might be the issue.
Make sure the og metadata resides inside the <head> tag as it won't be looking for them anywhere else. If you define them in the <body> tag or some other place, it will just ignore them.
If the pages have been liked before you added the metadata, you need to refresh the cache Facebook has for the page by providing the url's to the Facebook linter tool.
If neither of those steps resolve the problem, please share the url/code.
As far as your question regarding authenticated pages goes, you could just add that metadata on the public, non-authenticated version of the page, without checking is it actually Facebook or not, as when someone shares the page, that same information becomes public regardless of the users who view the share have access to the page or not.
After some further digging, I found a way to work with the "sharer.php" functionality to specify exactly the Image, Url, Title, and Description I want displayed, without relying on the OG meta tags. This will work for both anonymously accessible pages and pages that require an authenticated user. The linked StackOverflow Q/A (http://stackoverflow.com/questions/2950189/facebook-share-doesnt-show-my-description-or-my-thumbnail) got me headed in the right direction, then after some digging, found some other posts in the Facebook developer forums (http://forum.developers.facebook.net/) by searching for "sharer.php". This one in particular got me to where I needed to be: http://forum.developers.facebook.net/viewtopic.php?id=101127
In essence, there is no need for the OG meta tags. Just ensure the pieces of your URL are correctly encoded and that you are using the correct parameter keys (i.e. "&p[title]=" rather than "&t=".
After removing the OG meta tags from our site/pages, I also modified our Facebook sharing button/link to render the following markup:
<a href="http://www.facebook.com/sharer.php?s=100&p[title]=Our+Site+Title&p[url]=http%3a%2f%2fus.oursite.com%2fdefault.aspx&p[images][0]=http%3a%2f%2fus.oursite.com%2fimages%2fFB_ShareThumbnail_US_90x85.png&p[summary]=Our+facebook+description+that+is+used+on+the+FB+share+page." target="_blank">
<img src="/images/fb_icon_20x20.png" />
</a>
Note that I was tempted to investigate whether I could find a parameter that allowed me to specify a default "message", but that was not a requirement for us, so perhaps later on I'll dig for that information.
How about this now:
https://developers.facebook.com/docs/sharing/webmasters/crawler
You just need to whitelist the facebook crawler
I'm trying to create a link that will share a page on Facebook. So far I've got:
href="http://www.facebook.com/sharer.php
?u=http%3A%2F%2Fwww.cnn.com%2F
&t=CNN%26s+website"
However, I'd really like to add some text that will go in the 'What's on your mind?' text box (especially as the t value gets overridden by the link's title). Does anyone know if this is possible?
Simplest way to share on facebook is:
https://www.facebook.com/sharer/sharer.php?u=xerosanyam.github.io"e=You_are_amazing
Bonus:
Simplest way to share on twitter is:
https://twitter.com/intent/tweet?via=xerosanyam&text=You_are_amazing
NOTE: #azure_ardee solution is no longer feasible. Facebook will not allow developers pre-fill messages. Developers may customize the story by providing OG meta tags, but it's up to the user to fill the message.
This is only possible if you are posting on the user's behalf, which requires the user authorizing your application with the publish_actions permission. AND even then:
please note that Facebook recommends using a user-initiated sharing modal.
Have a look at this answer.
You can't do this using sharer.php, but you can do something similar using the Dialog API. http://developers.facebook.com/docs/reference/dialogs/
http://www.facebook.com/dialog/feed?
app_id=123050457758183&
link=http://developers.facebook.com/docs/reference/dialogs/&
picture=http://fbrell.com/f8.jpg&
name=Facebook%20Dialogs&
caption=Reference%20Documentation&
description=Dialogs%20provide%20a%20simple,%20consistent%20interface%20for%20applications%20to%20interact%20with%20users.&
message=Facebook%20Dialogs%20are%20so%20easy!&
redirect_uri=http://www.example.com/response
The catch is you must create a dummy Facebook application just to have an app_id. Note that your Facebook application doesn't have to do ANYTHING at all. Just be sure that it is properly configured, and you should be all set.
November 2021 update
The feed part of the Dialog API no longer includes the message field in the message. It is not included in the feed dialog documentation. The fields picture, name, caption, and description are now deprecated.
Therefore, for the purpose of sharing to the wall, you're better off with sharer.php, which does not require an app_id, and therefore does not need registering an app:
http://www.facebook.com/sharer.php?u=https://example.com
Like #Ardee said you sharer.php uses data from the meta tags, the Dialog API accepts parameters. Facebook have removed the ability to use the message parameter but you can use the quote parameter which can be useful in a lot of cases e.g.
https://www.facebook.com/dialog/share?
app_id=[your-app-id]
&display=popup
&title=This+is+the+title+parameter
&description=This+is+the+description+parameter
"e=This+is+the+quote+parameter
&caption=This+is+the+caption+parameter
&href=https%3A%2F%2Fdevelopers.facebook.com%2Fdocs%2F
&redirect_uri=https%3A%2F%2Fwww.[url-in-your-accepted-list].com
Just have to create an app id:
https://developers.facebook.com/docs/apps/register
Then make sure the redirect url domain is listed in the accepted domains for that app.
To add some text, what I did some time ago , if the link you are sharing its a page you can modify. You can add some meta-tags to the shared page:
<meta name="title" content="The title you want" />
<meta name="description" content="The text you want to insert " />
<link rel="image_src" href="A thumbnail you can show" / >
It's a small hack. Although the old share button has been replaced by the "like"/"recommend" button where you can add a comment if you use the XFBML version. More info her:
http://developers.facebook.com/docs/reference/plugins/like/
Like said in docs, use
<meta property="og:url" content="http://www.your-domain.com/your-page.html" />
<meta property="og:type" content="website" />
<meta property="og:title" content="Your Website Title" />
<meta property="og:description" content="Your description" />
<meta property="og:image" content="http://www.your-domain.com/path/image.jpg" />
image size recommended: 1 200 x 630
Facebook does not allow you to change the "What's on your mind?" text box, unless of course you're developing an application for use on Facebook.
I don't think this is possible in the Dialog API, which triggers starting a message on Messenger. (Note: this is different from "posting to your wall" in the accepted answer, the difference being /dialog/send instead of /dialog/feed).
For example:
http://www.facebook.com/dialog/send?
app_id=123050457758183&
link=http://developers.facebook.com/docs/reference/dialogs/&
redirect_uri=http://www.example.com/response
See the Facebook documentation. As of November 2021, the documentation does not show the fields picture, name, caption, description: they are populated from the Open Graph tags of the website. I tried adding the field message and it failed to produce any text, but the link still redirects to Messenger.
When someone posts a link to a web site in Facebook, it populates the link preview box with a photo and some text from the site.
If someone posts a link to my site in Facebook, it is generally just get the site's domain name and one of the images that appears on the site. No text appears.
I would like to be able to control what text and images appear in the link. Is there a specification that they use? Can I provide some metadata so Facebook will display what I want?
Here is Facebook's developer page on their share function.
Basically there are some simple metatags you can use to optimize what appears on FB
<meta name="title" content="title" />
<meta name="description" content="description " />
<link rel="image_src" href="thumbnail_image" / >
AND:
The wiki article doesn't mention this, but Facebook CACHES the results of your site for awhile. So, if you're debugging & doing quick iterations, you either need to wait awhile, or rename the page (index2.html, index3.html, etc) until you find something that works.
I am trying to implement share this method. I am using the code as follows
http://www.facebook.com/share.php?u=my_website_url
Now when Facebook is showing it showing some thumbnails at left side. These images are picked from my website. How can I pick a particular image as thumbnail or at least stop it showing thumbnail?
You can check it with my blog address.
From Facebook's spec, use a code like this:
<meta property="og:image" content="http://siim.lepisk.com/wp-content/uploads/2011/01/siim-blog-fb.png" />
Source: Facebook Share
This blog post seems to have your answer:
http://blog.capstrat.com/articles/facebook-share-thumbnail-image/
Specifically, use a tag like the following:
<link rel="image_src"
type="image/jpeg"
href="http://www.domain.com/path/icon-facebook.gif" />
The name of the image must be the same as in the example.
Click "Making Sure the Preview Works"
Note: Tags can be correct but Facebook only scrapes every 24 hours, according to their documentation. Use the Facebook Lint page to get the image into Facebook.
http://developers.facebook.com/tools/lint/
My tags were correct but Facebook only scrapes every 24 hours, according to their documentation. Using the Facebook Lint page got the image into Facebook.
Enter your URL here and FB will update the metadata from your page:
https://developers.facebook.com/tools/debug (updated link)
Facebook uses og:tags and the Open Graph Protocol to decipher what information to display when previewing your URL in a share dialog
or in a news feed on facebook.
The og:tags contain information such as :
The title of the page
The type of page
The URL
The websites name
A description of the page
Facebook user_id's of administrators of the page ( on facebook )
Here is an example ( taken from the facebook documentation ) of some og:tags
<meta property="og:title" content="The Rock"/>
<meta property="og:type" content="movie"/>
<meta property="og:url" content="http://www.imdb.com/title/tt0117500/"/>
<meta property="og:image" content="http://ia.media-imdb.com/rock.jpg"/>
Once you have implemented the correct markup of the og:tags and set their values, you can test how facebook will view your URL by using the Facebook Debugger. The debugger tool will also highlight any problems it finds with the og:tags on the page or lack there-of.
One thing to keep in mind is that facebook does do some caching with regard to this information, so in order for changes to take effect your page will have t be scraped as stated in the documentation :
Editing Meta Tags
You can update the attributes of your page by updating your page's
tags. Note that og:title and og:type are only editable
initially - after your page receives 50 likes the title becomes fixed,
and after your page receives 10,000 likes the type becomes fixed.
These properties are fixed to avoid surprising users who have liked
the page already. Changing the title or type tags after these limits
are reached does nothing, your page retains the original title and
type.
For the changes to be reflected on Facebook, you must force your page
to be scraped. The page is scraped when an admin for the page clicks
the Like button or when the URL is entered into the Facebook URL
Linter Facebook Debugger...
I see that all the answers provided are correct. However, one important detail was overlooked: The size of the image MUST be at least 200 X 200 px, otherwise Facebook will substitute the thumbnail with the first available image that meets the criteria on the page. Another fact is that the minimum required is to include the 3 metas that Facebook requires for the og:image to take effect:
<meta property="og:title" content="Title of the page" />
<!-- NEXT LINE Even if page is dynamically generated and URL contains query parameters -->
<meta property="og:url" content="http://yoursite.com" />
<meta property="og:image" content="http://convertaholics.com/convertaholics-og.png" />
Debug your page with Facebook debugger and fix all the warnings and it should work like a charm!
https://developers.facebook.com/tools/debug
I was having the same problems and believe I have solved it. I used the link meta tag as mentioned here to point to the image I wanted, but the key is that if you do that FB won't pull any other images as choices. Also if your image is too big, you won't have any choices at all.
Here's how I fixed my site http://gnorml.com/blog/facebook-link-thumbnails/
Here’s how this works all:
You need the ability to access the HTML on the particular webpage you are sharing. It'll probably work site wide too if you use a common header file. I have not tried this, but it should work. You'll just get the same image for all pages if you do this though.
You need to add these HTML meta tags into page in the . It will not work if you put it in the . Make sure to customize per your a) image, b) description, c) URL, and d) title.
A Real Example.
<meta property="og:image" content="http://www.coachesneedsocial.com/wp-content/uploads/2014/12/BannerWCircleImages-1.jpg" />
<meta property="og:description" content="Coaches share their secrets to success so you can rock 2015." />
<meta property="og:url"content="http://www.coachesneedsocial.com/coacheswisdomtelesummit/" />
<meta property="og:title" content="Coaches Wisdom Telesummit" />
Save
Open a fresh Facebook post, and retry the page you wanted to share.
If you are having trouble… you can debug it with this Facebook tool. It looks more geeky than it is. It tells you what Facebook is seeing when you post in the URL to share.
https://developers.facebook.com/tools/debug/og/object/
Big Tip.. make sure the “quote marks” are the same in your HTML (they should look like 2 straight marks and no curves… sometimes programs change these to different fonts and it goofs up the code.
Sharing on Facebook: How to Improve Your Results by Customizing the Image, Title, and Text
From the link above. For the best possible share, you'll want to suggest 3 pieces of data in your HTML:
Title
Short description
Image
This accomplished by the following, placed inside the 'head' tag of your HTML:
Title: <title>INSERT POST TITLE</title>
Image: <meta property=og:image content="http://site.com/YOUR_IMAGE.jpg"/>
Description: <meta name=description content="INSERT YOUR SUMMARY TEXT"/>
If you website is static HTML, you'll have to do this for every page using your HTML editor.
If you're using a CMS like Drupal, you can automate a lot of it (see above link). If you use wordpress, you can probably implement something similar using the Drupal example as a guideline. I hope you found these useful.
Finally, you can always manually edit your share posts. See this example with illustrations.
I also had an issue on a site I was working on last week. I implemented a like box and tested the like box. Then I went ahead to add an image to my header (the ob:image meta). Still the correct image did not show up on my facebook notification.
I tried everything, and came to the conclusion that every single implementation of a like button is cached. So let's say you clock the Like button on url A, then you specify an image in the header and you test it by clicking the Luke button again on url A. You won't see the image as the page is cached. The image will show up when you click on the Like button on page B.
To reset the cache, you have to use the lint debugger tool that's mentioned above, and validate all the Urls for those that are cached... That's the only thing that worked for me.
The easiest way I found to set Facebook Open Graph to every Joomla article, was to place in com_content/article/default.php override, next code:
$app = JFactory::getApplication();
$path = JURI::root();
$document = JFactory::getDocument();
$document->addCustomTag('<meta property="og:title" content="YOUR SITE TITLE" />');
$document->addCustomTag('<meta property="og:name" content="YOUR SITE NAME" />');
$document->addCustomTag('<meta property="og:description" content="YOUR SITE DESCRIPTION" />');
$document->addCustomTag('<meta property="og:site_name" content="YOUR SITE NAME" />');
if (isset($images->image_fulltext) and !empty($images->image_fulltext)) :
$document->addCustomTag('<meta property="og:image" content="'.$path.'<?php echo htmlspecialchars($images->image_fulltext); ?>" />');
else :
$document->addCustomTag('<meta property="og:image" content="'.$path.'images/logo.png" />');
endif;
This will place meta og tags in the head with details from current article.
