What Are Open Graph Tags?

Open Graph (OG) tags are meta tags that control how your web page appears when shared on social media platforms like Facebook, LinkedIn, and Twitter. The OG protocol, originally created by Facebook, defines a set of properties that describe your content — title, description, image URL, content type, and more. When someone shares your page, social platforms read these tags to generate a rich preview card with an image, headline, and summary. Without OG tags, these platforms will attempt to guess the content, often resulting in broken or misleading previews.

Why OG Tags Matter for SEO and Engagement

While OG tags aren't a direct ranking factor, they significantly impact click-through rates from social media shares. A well-formatted preview card with a compelling image and description can increase engagement by 2-3x compared to plain link shares. Twitter Card tags work similarly and control how your page appears specifically on Twitter. The four required OG tags are og:title, og:description, og:image, and og:url. For Twitter, you should also include twitter:card (set to summary_large_image for best results).

Common OG Tag Issues

The most common issues include missing og:image tags (resulting in no image in previews), overly long titles that get truncated, descriptions that don't match the page content, and relative image URLs that resolve incorrectly when shared. This tool checks for all required and recommended tags, highlights what's missing, and shows you exactly how your page will appear when shared on social media.
