Introducing the Meta Description Tester — Preview Your SERP Snippet

A meta description that looks fine by character count can still get cut off mid-sentence in Google — because Google truncates by pixels, not characters. The new Meta Description Tester shows you exactly how your snippet will render before you publish.

What it does

• Character and word counts, unicode-accurate.
• Pixel-width estimate using Google’s snippet font metrics.
• Desktop and mobile truncation detection.
• A live Google-style SERP snippet preview for both devices.
• Length guidance against the 120–158 character sweet spot.

Why it matters

Mobile budgets are tighter than desktop, so a description that fits on a monitor can still be trimmed on a phone — where most searches happen. Front-loading your message keeps the call to action visible no matter where the cut falls. Our guide to meta descriptions, pixels, and truncation explains the rules, and you can keep duplicate URLs from competing with the Canonical Tag Generator.

Free, and private

The Meta Description Tester is free and runs entirely in your browser — nothing you type is uploaded or stored. A future Pro tier is planned for bulk CSV testing and an API, but the single-snippet tester stays free.
