Why should I add Twitter Cards

When you add twitter cards to your blog, your blog posts will look more elegant when shared on twitter. This will apply to any twitter account and not just yours.People will be able to get a quick preview of your Blog Post even before they actually visit your blog.

How to add Twitter Cards to Blogger

Adding twitter cards is really easy and you can do the same by following the below steps
Edit your template and add the Twitter card markup.  - Login to your Blogger account and
and go to Template > Edit HTML
blogger-edit-html
Click somewhere within the Template Editor and press Ctrl + F to search within the template.
Search for </head> and paste the below code just above that . You will have to modify the first  @bloggerplugins in the below code with the name of the twitter account which you use for your blog.You can modify the second @bloggerplugins to the name of the blog author’s twitter account. Since I don’t have a separate one, I am using the same at both places but if you have separate accounts, then do use them
<b:if cond='data:blog.pageType == &quot;item&quot;'>
    <b:if cond='data:blog.postImageThumbnailUrl'>
      <b:if cond='data:blog.metaDescription'>
        <meta content='summary' name='twitter:card'/>
        <meta content='@bloggerplugins' name='twitter:site'/>
        <meta content='@bloggerplugins' name='twitter:creator'/>
        <meta expr:content='data:blog.pageName' name='twitter:title'/>
        <meta expr:content='data:blog.metaDescription' name='twitter:description'/>
        <meta expr:content='data:blog.postImageThumbnailUrl' name='twitter:image:src'/>
        <meta expr:content='data:blog.homepageUrl' name='twitter:domain'/>
      </b:if>
    </b:if>
</b:if>
so that it looks like
add-twitter-card-markup
and Save your template.
Next Step is to add Meta Descriptions & images to your Blogger Post – While making a blogger post, make sure that you add a Search Description to it.Also make sure that you have added an image to the post. If you don’t do any of these, the post won’t display a twitter card. Adding a Search Meta Description to your blogger post will also help in improving the way your posts are presented on Search Engines. So make sure that you add it to every post that you make.
Final step is to request for approval from Twitter.To do that Go to Twitter Developer Site at https://dev.twitter.com/docs/cards/validation/validator and go to the Validate & Apply tab
Give the URL of your blog post(To which you have added a search description and image) and click on the go button. Twitter will validate the card markup and if everything is ok it will show an option to request for approval. Do that and once it gets approved you will get an email from Twitter. This process takes around 5-10 day as of now.
Once approved, all your posts which have an image and search description will start showing twitter cards when you or anyone else shares your post to twitter. This will also reflect to old tweets.
If you have any more queries do let us know via comments or the Forum.
Happy Blogging!

  6. Hi AJ,

    I am in no way a connoisseur of html or web development, so bare with me.
    I tried to create a twitter "summary_large_image" card type for my blog which is quite similar to the "photo" type card. I applied and got approved from the twitter development site.

    However, the problem is that the "data:blog.postImageThumbnailUrl" tag that i used for the image og, is not cutting it, as blogger generates a s72-c size thumbnail, and that isn't big enough for the "summary_large_size" or "photo" type twitter card.

    I used this fix I fished from another article of yours:

    meta expr:content='"https://images1-focus-opensocial.googleusercontent.com/gadgets/proxy?container=focus&gadget=a&rewriteMime=image&resize_h=610&resize_w=610&url=" + data:blog.postImageThumbnailUrl' name='twitter:image'/

    which partly works, as it generates a 610 image for the twitter card. However, the problem is that it stil uses the default s72-c thumbnail and stretches it, which makes it look pixelated.


    My question is, if there is a way to implement on that above tag, something to replace the s72-c size with s610. Perhaps (and I am only guessing here) with some command along the lines of your previous article:
    http://www.bloggerplugins.org/2012/01/wrong-description-image-facebook.html

    or something like that, but within that meta tag?

    Do you think that's possible?


    I appreciate any thoughts on the matter, and thank you in advance.

    Kind regards,

    A.L.

  11. Receiving same as Cornelo - invalid card type. Rechecked settings and everything works okay in preview, it just won't validate because of the card type error. Help please.

  12. Re my post of 5mins ago. I tried the Validate & Apply process with several different Blogger post URLs and eventually found one that worked okay.

    Can't see any obvious differences in the failed and successful URLs/posts.

  13. If we just want the twitter "card" Do we need to ask for approval from Twitter?

    ReplyDelete
  14. Do I have to fill out any of the info on the try cards? Or just go right to the Validate and apply? I am getting the "Invalid card type" over and over again. I checked my settings and everything else is right.
