2025.11.10

How to Use

  1. Pick device: toggle Desktop / Mobile at the top.
  2. Enter Title in the Title field.
    • A pixel width meter (Canvas-based) updates live. Limits:
      • Desktop: ≤ 600px
      • Mobile: ≤ 550px
    • If the title exceeds the limit, you’ll see “Title may truncate.”
  3. Enter Meta Description in the textarea.
    • A counter shows character count (recommend ~155–160 chars).
  4. Preview: The card below renders a Google-like snippet with title, URL stub, and description.

Notes & Caveats

  • Approximation: Real SERPs vary by device, bolding, site name injection, date stamps, and UI tests. This is a best-effort preview, not a replica.
  • Font variance: Pixel width is measured via Canvas (600 18px system-ui). Local font differences can cause minor discrepancies.
  • Description clamping: Preview clamps to ~2 lines; Google’s actual line count is query- and UI-dependent.
  • URL is a placeholder (www.example.com). Real breadcrumb paths may differ.
  • Rule of thumb:
    • Title: Desktop ≤ 600px / Mobile ≤ 550px
    • Meta description: ~155–160 chars (actual limits vary)
