What is an Open Graph tag?

Open Graph tags are meta tags in the of an HTML page that control how the page appears when shared on social platforms like Facebook, LinkedIn, and Slack. The most important are og:title, og:description, og:image, and og:url.

What does the OG score mean?

The OG score is a 0–100 rating based on how many required and recommended tags are present and valid. Each error deducts 25 points and each warning deducts 10 points. A score of 90+ means your tags are complete and well-formed.

Why is og:image required?

Without og:image, social platforms will either show no image or pick a random image from the page. A proper og:image makes your shared links visually compelling and increases click-through rates significantly.

What is the difference between og:title and twitter:title?

og:title is used by most platforms (Facebook, LinkedIn, Slack, Discord). twitter:title is used specifically by Twitter/X. If twitter:title is absent, Twitter falls back to og:title, so you only need twitter:title if you want a different title on Twitter.

Does the validator upload or store my URL?

The validator fetches the URL server-side solely to read the HTML head section. No data is stored or logged.
