What are Open Graph (OG) tags?

Open Graph is an internet protocol originally created by Facebook. It uses specific meta tags (like `og:title` and `og:image`) to dictate exactly how a webpage looks when shared on social media.

Which platforms use Open Graph?

Almost all major platforms use it today, including Facebook, LinkedIn, Discord, Slack, and iMessage. X (Twitter) has its own 'Twitter Cards' but will fall back to Open Graph if X-specific tags are missing.

What is the best size for an Open Graph image?

The universally recommended size for an `og:image` is 1200 x 630 pixels (an aspect ratio of 1.91:1). This ensures it looks crisp on high-resolution screens.

Why is my shared link showing the wrong image?

Social media platforms aggressively cache OG data. If you recently updated your `og:image`, you need to use the Facebook Sharing Debugger or LinkedIn Post Inspector to force them to scrape the new data.

Do OG tags affect Google SEO?

Not directly. Google ranks pages based on standard HTML tags (Title, Meta Description). However, great OG tags increase social media clicks, which can drive traffic and indirectly benefit your brand.

What is the `og:type` tag?

It defines the type of content you are sharing. Most pages should use `og:type="website"`, but blog posts should use `og:type="article"`.

Can I use a relative URL for the og:image?

No. You MUST use an absolute URL (e.g., `https://example.com/image.jpg`). Social platforms cannot resolve relative URLs (`/image.jpg`) from their own servers.

What happens if I don't use Open Graph tags?

If you don't provide OG tags, social platforms will randomly guess by scraping your standard Title tag and grabbing the first random image they find on your page (often a tiny logo or a completely unrelated picture).

Healthy Tips & Guidelines

Always keep the most important text and graphics in the absolute center of your og:image, as some platforms (like WhatsApp) crop the image into a square.
Keep your og:title under 60 characters and og:description under 110 characters, or they will be truncated on mobile devices.
Always include Twitter Card tags (twitter:card="summary_large_image") alongside your OG tags to ensure massive, beautiful previews on X.
Use SVG or WebP formats for your website, but stick to standard JPG or PNG for your og:image, as some older messaging apps cannot render modern formats.

Common Mistakes to Avoid

Using an image that is too small (e.g., 200x200), resulting in a tiny thumbnail instead of a large, eye-catching banner in the social feed.
Using relative URLs for the og:image or og:url, which causes the image preview to fail completely.
Forgetting to clear the cache using the platform's Debugger tool after fixing a mistake, leading to endless frustration.
Assuming that a great standard Meta Description means you don't need an og:description (they serve different purposes).
