   Hi! I have a free wordpress.com blog, and I’m not sure how to add twitter cards to that. I don’t know if I can edit the html of my theme without a plugin (if I can, I don’t know how to find the html code) (super new to WP) is there any way to add twitter cards for free

     You would need to reach out to WordPress.com for what they currently have available.

   Thank you! It took awhile for this to work I guess because cache needed to be cleared but this is the ONLY solution I found that worked.

   Question about this, when I am posting a link from my site on Twitter, the preview image is only showing the Wordpress W logo instead of what I set in Yoast. Is it just a matter of waiting it out or a, I doing something wrong?

   Responder

   • WPBeginner Support

     You may want to ensure you’ve cleared any caching on your site for twitter to get the correct image and after that, you would need to wait for Twitter’s cache to clear.

   Hey there, very late to this article but am wondering how to amend the php code to produce the large image with summary card.

   I’ve given it a shot but not managed it yet. Ideas and advice appreciated.

   cheers

    I’ve done all the steps using Yoast and validated my url – but there is still no image coming up when I post my URL on Twitter? It said this:

    Sarah Bridge
    The card for your website will look a little something like this!

    and underneath on the right hand side it has the correct words but on the left hand side where an image should be there’s nothing but a grey box with what looks like a grey scroll in it. You can click on it to get to my website but I’d like a image there rather than a grey box. Any thoughts?

    Have successfully done this in the past. However, it was always when using summary card with large image (which is set as the default in my Yoast settings). Now trying to post summary card (regular, not large image), but Yoast is overriding it to summary card large image. How do I prevent this?

    As a note, I’m doing both methods: adding info to Yoast plug in and writing metadata tags in a plug in.

    This was very helpful! Thanks. Did it and the twitter cards automatically came up even for previous tweets.

    ERROR: Required meta tag missing (twitter:text:description)

    Getting this error

    Responder

14. Nick Farrell

    You can also just throw your meta tags right into the body of your post. Not the ideal way, since this creates empty white space where your tags are, but it’s a good workaround for those having trouble.

    Responder

15. Laurel

    If the php code above seems to break your site, it could be that your server doesn’t use php short tags (using “<?" as an opening tag instead of "<?php"). Try this version instead:

    Hi thanks for the informative post. However I did all this and when testing my site through the card validator, was told it was unable to generate image because my site isn’t whitelisted! Any idea what I can do?

    Hi,

    I realise this is an old post,

    IF you HARDCODE into your header.php; make sure you change the values line 10 and 19 as these point to the contributors account so be sure to change them to yours.

    just sayin …

    Is there a way to automatically notify the twitter validator when a post/page is updated?

    I have a site that gets content published automatically from a source without a featured image so once I manually add the image I also have to manually validate the post/page again to get the cards to show on twitter.

    Was hoping there could be some way to automatically ping the twitter validator when a page/post is updated.

    $twitter_thumb = ‘url of imag’;
    }
    $twitter_name = str_replace(‘@’, ”, get_the_author_meta(‘twitter’));

    Another awesome post … great stuff!

    For anyone having issues with the image being display (I have Summary selected as my Twitter Card option) just make sure you are using a featured image, as this is where it pulls from.

    Without this specified, what I saw was my site logo (which was way too big for the Summary image)

    Responder

    • WPBeginner Support

      If you are using code method, then please try using the plugin method. If you are already using the plugin method, then try repeating all the steps carefully.

    i have a question that when where to upload it on all pages and post or on home page only.

    bcoz when i share any link of my blog on twitter after adding this in header every time same image appears.

    Responder

    • Adrian Robertson

      Is it your site logo that appears?
      Just check that you have a feature image set against your post, and it should pull from there

    Found this article and followed the steps to set up Twitter Cards since we already had Yoast. We want to use the video Player Card but that doesn’t appear to be an option. Do we need to use a different plug in, or is that option available?

    I”m using twitter cards through my Yoast SEO, however when I post I have a link and a view summary button that people have to click to see my pictures. I want the pictures to be auto populated without the need for a click. How do I make that happen?

    Hi,

    Thanks for your tutorial. I have tried with above code. But can you please explain how to make Twitter card working for multiple accounts.

    I have ten different twitter pages where same post will go out as Twitter card.

    So do I need to repeat this below line 10 times with different names:

    …..

    …

    ….
    ….

    Please suggest?

    Thanks!

    Responder

    • jas

      code doesn’t shows in my previous comment I mean to say meta tag with Twitter site name need to get repeated with different names?

      <meta name="twitter:creator" value="@” />

    The Yoast solution did not work for me. I followed the instructions (3 times to make sure), and the Card Validator sees my metadata but tells me I have no card.
    Also, neither the Preview Tool nor the “FIll out This Form” links worked:
    https://dev.twitter.com/docs/cards/preview

    Maybe this solution is already history?

    I had done this and Twitter cards were working perfectly for months. Suddenly the past few days they’ve stopped working. What can I do?

37. Megan Kubasch

    So I have installed WP SEO by Yoast, and I have followed all of the instructions up to the point where I insert the Card URL on the Preview page for the Card Validator on Twitter. What URL am I supposed to Insert? I have used my URL for my blog, but it comes up with an error, saying No Card Found (Card Error). Any help you can provide would be greatly appreciated.

    Responder

    • Paula

      It will not do it for a main blog page. You have to enter a post page url. So something like http://www.blogname.com/title-of-blog-post not http://www.blogname.com Hope that helps!

38. Eric Yoffie

    My twitter card has been approved, but I don’t know how to make it work. Am I supposed to fill out a form? I am a WordPress user.

    Responder

39. Lauren Riley

    This is really useful thank you.

    One thing, we have enabled this using the WordPress Yoast SEO Plug-in and set up a Twitter card manually entering all of the information on the card validator for one blog post.

    This worked, however when I tweet a link to my other blog posts it doesn’t pull through the Twitter card. Do you have to set up the Twitter cards for each blog post or should it do it automatically for each blog post?

40. Manuel Echeverry

    graciass!!! thank you! finally I managed to submit my request to twitter, hopefully i will get my card approved

41. Ruth

    Oh, and ps
    Do we have to approve each post, or will that be automatic after our first post was approved… Again, thank you

42. Ruth

    Thanks, it works great, except for one thing: I can’t get an image to be included. How would I do that,

43. Karan Singh

    when i install this plugin then it is asking for “You’ve just installed WordPress SEO by Yoast. Please helps us improve it by allowing us to gather anonymous usage stats so we know which configurations, plugins and themes to test with” Allow Tracking or not, what should i do,

    I’m currently stuck trying to validate twitter:creator. When I look at the source for one of my posts, I don’t see the twitter:creator meta tag at all. Would you mind, pointing me in the right direction? I’m hard-coding it.

    Hi,

    It’s great but because we call the excerpt outside the loop (header), people could get bad surprises for their description.

    So here is a good snippet from uplifted.net that fixes the problem :

    function get_excerpt_by_id($post_id){
    $the_post = get_post($post_id); //Gets post ID
    $the_excerpt = $the_post->post_content; //Gets post_content to be used as a basis for the excerpt
    $excerpt_length = 35; //Sets excerpt length by word count
    $the_excerpt = strip_tags(strip_shortcodes($the_excerpt)); //Strips tags and images
    $words = explode(‘ ‘, $the_excerpt, $excerpt_length + 1);
    if(count($words) > $excerpt_length) :
    array_pop($words);
    array_push($words, ‘…’);
    $the_excerpt = implode(‘ ‘, $words);
    endif;
    $the_excerpt = ” . $the_excerpt . ”;
    return $the_excerpt;
    }

    Then you might replace get_the_excerpt() with this :
    get_excerpt_by_id($post_id)

    Thanks.

    Responder

    • Julien Maury

      Sorry that wasn’t exactly that :

      Call the function this way : get_excerpt_by_id($post->ID) otherwise you’ll get notice !
      $post_id is undefined.

      Plus get_the_excerpt() is deprecated.

      You can also add an esc_attr() on $the_excerpt to avoid broken meta if the excerpt has quotes

      Thanks !

      • Julien Maury

        Hi,
        There’s no need to use any code. But still my plugin allows you to choose which type of card you want to use on each post. Moreover you can change meta creator (guest blogging) per each post too. I think it’s worthy

51. Sai Liou

    Thank you for the article! I went with method #1. In the twitter preview, I’m only seeing the summary of the post and not the image. I’ve updated the robot.txt file to allow twitterbot. However, it’s still not showing any image in the preview. Any thoughts on this? Thank you in advance.

    Responder

    • Editorial Staff

      Look in your view:source to see if you have the image tags. The image is usually pulled from your featured image.
