Boad Tools Open Graph Social Preview is a free tool to test, optimize, and generate meta tags for Facebook, Twitter/X, LinkedIn, Discord, and Google SERPs.
Why Open Graph meta tags matter
When people share links to your website or blog posts on social networks like X (Twitter), LinkedIn, Slack, and Facebook, those platforms look for Open Graph (og:) and Twitter Card meta tags in your HTML header.
Without proper meta tags, platforms display an empty or broken thumbnail and an ugly URL snippet, leading to an estimated 40-70% drop in click-through rates. With optimized tags and a high-resolution 1200x630 banner, your links appear polished, engaging, and professional.
How to use this tool
- Fill in Page Details: Add your URL, compelling meta title (under 60 chars), and concise meta description (under 160 chars).
- Upload or Link Social Image: Paste an image URL or click the upload button to preview your local graphic with instant zero-upload rendering.
- Switch Platforms: Toggle between Google SERP (desktop & mobile), Twitter / X, Facebook, LinkedIn, and Discord to verify how your links render.
- Copy HTML Tags: Click "Copy Meta Tags" and paste the generated snippet directly inside your site's <head> tag.
