For some reason the Tumblr variable {MetaDescription} besides the text of a post include also the title.
For example:
Title: How to eat
Text: I will explain you in this post how...
How is inside Tumblr custom tool:
meta name="description" content="{MetaDescription}"
This is how shows the meta description online in that post:
meta name="description" content="How to eat I will explain you in this post how..."
This is a problem for SEO. There's any way to show just the text of every post changing/adding something in the code related to the meta name="description"?
Hello please help me: if I paste link of my site to facebook message, facebook processes it to thumbnail + some text. There is text "Shop powered by PrestaShop". How do I change it?
Prestashop version 1.6.1.4.
Site address : http://myfleur.cz/
Thanks for any help.
Facebook's crawler scrapes the HTML of the URL that is shared. On a regular HTML page (similar to your case) this content is basic and may be incorrect, because the scraper has to guess which content is important, and which is not.
The good news is that you can take control of what the Facebook crawler picks up from each page by using Open Graph meta tags. These tags provide structured info about the page such as the title, description, preview image, and more.
So just add these meta tags in your homepage:
<meta property="og:url" content="<your-webpage-url>" />
<meta property="og:title" content="<new-title>" />
<meta property="og:image" content="<new-image-url>" />
(You can add other meta tags also as mentioned in the link mentioned)
P.S. You can use this url to debug, which content facebook is scraping from your website.
Hope that helps!
The solution in that case is go to
Preferences -> SEO & URLs -> index (edit)
and change there the Meta-Description.
I am using JS SDK for the send dialog:
FB.ui({
app_id: appId,
method: 'send',
link: window.location.protocol+'//'+server+'/xxxxx',
name: 'name',
description: 'description',
to: '1111111111'
});
The 'name' and 'description' parameters are ignored.
I understood that using metadata tags is the solution.
What tags should I use for the name and description?
The metadata tags are called Open Graph tags. There are many of types data that can be included in these headers, if you are curious then read up about the options here and here.
To specify just the name and the description, you should use the og:title and og:description tags in the HTML of the URL being sent, like this:
<meta property="og:title" content="The Name Goes Here" />
<meta property="og:description" content="Some text about this link goes here" />
One thing to remember is that Facebook caches this data quite aggressively - so you might find yourself wondering why when you've changed the tag, the text in the send dialog is not changing. If this happens, paste the URL into Facebook's Object Debugger - https://developers.facebook.com/tools/debug and it should clear their cached version.
Where can I find full docs for using http://www.facebook.com/sharer.php ? I want to know all aviable params to this url for sharing something.
P.S. http://developers.facebook.com/docs/reference/plugins/like/ gave me no info.
There's no documentation because the new way for sharing is the Like button. But you can add do http://www.facebook.com/sharer.php?u=yourURL.
To specify the image and the description, you have to add the following meta data in the header of your website.
Image
<meta property="og:image" content="URL of your image" />
Description
<meta name="description" content="Your description" />
Facebook will use the meta og:image to find the image and the meta description for the description.
Cheers
The official docs for the sharer are pretty sparse and virtually non-existent. You used to be able to send a whole host of params to the Facebook sharer.php
Facebook have since made an update (feb/mar 2014) and it now looks at the OpenGraph tags above anything else. See response from FB developer
They now recommend using the Feed Dialog method of sharing.
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.

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!

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.

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.
