Introduction

When you share a link on Twitter, have you noticed how some posts display beautiful images, compelling titles, and descriptions, while others just show plain text? The difference lies in Twitter Card markup - special HTML meta tags that transform your boring links into engaging, visual content cards.

Twitter Cards are like mini-advertisements for your content. They can dramatically increase engagement, clicks, and shares by making your content stand out in the Twitter feed. Without proper Twitter Card markup, your shared content looks unprofessional and gets less attention.

In this guide, you'll learn how to implement Twitter Card markup correctly, turning your website links into eye-catching social media content that people actually want to click.

What are Twitter Cards?

Twitter Cards are HTML meta tags that provide Twitter with structured information about your webpage content. When someone shares your URL on Twitter, these tags tell Twitter exactly what image, title, and description to display in the tweet.

Think of Twitter Cards as your content's preview window - they give Twitter users a sneak peek of what they'll find when they click your link, making them more likely to engage with your content.

How Twitter Cards Work

When a URL is shared on Twitter, Twitter's crawler visits your webpage and looks for specific meta tags in the HTML head section. These tags contain the information Twitter needs to create an attractive card display for your content.

Types of Twitter Cards

Summary Card

The most common type, perfect for most websites and blog posts:
