Twitter is a goldmine for content marketing, receiving 6,000 tweets every second. That’s 350k per minute or 200 billion a year. With so much traffic, it’s crucial to catch your audience’s attention quickly. And you do this with content that’s engaging, useful, and well-organized.
Twitter Cards let your content speak volumes even within 280 characters. They make your tweets stand out with rich media like images, videos, and summaries, which drive more traffic, conversions, and engagement.
Read on to find out more about Twitter Cards and how to use the Twitter Card Validator and tools to keep your content from getting lost in the crowd.

What is the Twitter Card Validator Tool?

The Twitter Card Validator tool checks whether your website is configured correctly to display Twitter Cards when shared on Twitter. Basically, it serves as a safety net to ensure that the card is functional before it is goes out.
Using a Twitter Card Validator is incredibly important, as you cannot be certain of the effectiveness of your codes until you know if they work or not.
Listed below are some best practices for Twitter website cards:


A Twitter Card’s most important part is its media. It needs to be eye-catching to compete with everything else in your prospects’ Twitter feed. It must be bright or visually moving to stop the user mid-scroll.


A large and bold headline is more likely to grab attention than a smaller, less prominent headline. Your headline should convey new information, not what you’ve already mentioned.


Twitter adds this automatically when you enter your landing page URL. Your URL should match your ad’s branding, otherwise, you risk losing prospects’ trust.

Social proof

How many comments, retweets, and likes your photo gets influences its success, and is known as social proof. Your prospects are more likely to believe your offer is valuable if you display more likes, shares, and positive comments.

Why You Need to Validate Your Twitter Cards

Here are a few reasons why you should validate your Twitter Card before sharing links on Twitter.

Enhance visibility

With Twitter Cards, you can make your tweets more engaging and eye-catching, making it more likely that your links will be seen and clicked.

Boost click-through rate

Twitter Cards lets you include information and media in your tweets, making them more informative and interesting, leading to more clicks.

Improve content representation

Twitter Cards give you more context and info about the content you’re sharing, so users know what they’re clicking on.

Potential to get featured

Twitter uses a feature called “Twitter Moments” which is a curated collection of tweets featuring events or trending topics. Using Twitter Cards increases your chances of getting featured in these Moments.

Increase engagement

Twitter Cards make it easier for users to interact with your content, such as watching videos or listening to audio. You’ll get more engagement with your tweets and content this way.
Keeping your Twitter Card in check can improve your visibility, click-through rate, representation, and engagement, or you can risk losing out.

How to Use the Twitter Card Validator Tool

Twitter Cards must be validated using the Validator tool before it can be used on Twitter. The following is a step-by-step process:
Visit the Twitter Card Validator page:
Enter the URL of the webpage you want to test.
After the page is shared on Twitter, the tool will check for Twitter Card tags and display a preview.
A new set of metadata will appear in the card preview panel. It will also display any errors. For whitelisting, player cards must be approved. For approval, click on the “Request Approval” button.
Once you have tested using the Twitter Validator tool, just tweet the URL to see the card appear below your tweet. It is a good idea to always double-check the card’s appearance when tweeting a link to your webpage, even if the validator says it’s valid.
The Twitter Card Validator can only check the markup on your webpage, so it cannot determine if it is the right one or even relevant to the page shared.

Verify Your Site with the Twitter Card Validator

Using this tool, you can verify how your site will appear when shared on Twitter so that relevant information and visuals are displayed when users share your site’s links. You can also use it to troubleshoot any performance issues.

Solve Twitter Card Errors with Meta Tags

A lack of meta tags can prevent your site from appearing correctly on Twitter. Meta tags are snippets of code that provide Twitter and other platforms with information about your site. Meta tags can be used to specify your site’s title, description, image, and other attributes.
Twitter Card’s most common error is “No metatags found”, which occurs when the preview is correct but does not appear on Twitter or the Twitter Card Validator does not display a preview.
To solve this, first check that your page has all the main HTML tags:
Summary Card: Description, title, thumbnail.
Summary Card with Large Image: A Summary Card with a prominent image.
App Card: A card that directs you to a mobile app.
Player Card: Displays video, audio, and media.
Note that the element must appear in the of your HTML document. Additionally, tags from images require a full HTTPS URL.
You must always refresh the validator page after making a change. The preview button alone is not enough.

Preview in the Tweet Composer

You can use Twitter’s native Tweet Composer as a Twitter Card validator to verify your site. You can preview your tweet before you publish it using Tweet Composer. By clicking on the eye icon at the bottom right corner of the text box, you can access it.
In the preview mode, you can also add media, polls, or emojis to your tweet. It can also help your tweets be free of typos, formatting errors, or unwanted content.

What are the Limitations of Twitter’s Card Validator?

While the Card Validator assists you in ensuring your tweets display attractively, it has the following limitations:
It only supports 4 types of cards: summary, summary_large_image, app, and player. Other types of cards, such as product or gallery, require a third-party service or custom creation.
All devices and platforms may not display your card the same way. Your card may look different on different screens, resolutions, and operating systems. To ensure that your card works as expected, test it on several devices and browsers.
It does not automatically update the cached version of your card. You will need to request a new validation when you make changes to your website’s metadata or content (e.g., ?card=1). Your old card version will be displayed if you don’t update it.
You cannot test your card’s functionality. The Card Validator will not check if your video or audio plays correctly, or if your callbacks work if you use a player card. To test these aspects, you will need to use tools like Twurl or test your card on your own.
