Designing share links that survive

A great share preview is a tiny landing page rendered by someone else's crawler. Treat it accordingly.

Why this matters today

og:title, og:description, og:image — the same three fields, repeated across a dozen platforms. Get them right once and every share looks intentional.

Your share preview is the only chapter most people will read.

In practice

Here is the part that turns theory into a habit:

• Start small — a single file, a single page, a single test.
• Measure twice. Trust the numbers, not the vibe.
• Keep an undo path. Reversible decisions buy you courage.

A note on tooling

Every tool on this site runs in your browser unless we say otherwise. That changes the trade-offs: nothing to upload, nothing to retain, nothing to leak. The downside is a small ceiling on file size and a dependency on your device's CPU — both acceptable for most editorial workflows.

Takeaway

Test in the platform's debugger before celebrating.
