The "New" Badge: How Long Does It Actually Sell?

A 14-table meze restaurant in Istanbul's Uskudar district left a "New" badge on two dishes for six months. Guests stopped seeing it long ago, because "new" had quietly lost its meaning. Below is what thMenu's anonymized order data reveals about the badge's real shelf life — and the lift a 21-day auto-expiry rule unlocks.

The 3-Week Sweet Spot

Across 1,400+ restaurants on thMenu, the pattern is consistent. Items tagged "New" outperform same-category peers by an average 52% in the first 21 days, with a 71% spike in week one, 48% in week two, and 37% in week three.

From day 22 onward the lift collapses. By week four it's only 8%; by week six it's statistically zero. Past week eight, dishes still wearing "New" actually underperform unbadged peers by roughly 4% — guests interpret a stale badge as a trust signal that something is off.

The 21-Day Auto-Expiry Rule

The Uskudar operator set a thMenu rule that automatically removes the "New" badge after 21 days. Fourteen weeks later, new items hitting their category's top-5 rose from 22% to 58%. The badge kept meaning what it said, so guests trusted and ordered it.

The rule rests on three settings:

• Duration: 21 calendar days (highest measured ROI).
• Clock start: from public publish date, not from when the item was created internally.
• Cooldown: 90 days before "New" can be reapplied — prevents badge inflation.

Life After "New": A Durability Track

Two follow-ups protect momentum once the badge drops. First, three days before expiry the kitchen gets a notification — the chef reviews speed of service and plating one last time. Second, the moment the badge is removed, the item is auto-promoted to the menu's "Trending" filter; that's a different social-proof signal and doesn't cause the same fatigue.

Track one number: the dish's day-28 order volume should sit at at least 40% of its day-7 volume. Below that line, the item was likely riding the badge — revisit recipe, photography, or remove it.

FAQ

What if I leave "New" longer than 21 days? Lift falls to 8% by week 4; after week 8 the dish underperforms unbadged peers by ~4%. The badge actively erodes trust.

When can I reapply "New" to the same item? 90 days is the safe default. A clear seasonal relaunch (e.g., a winter version) is a defensible exception.

How do I enable auto-expiry in thMenu? Admin panel → Products → Badge Settings → toggle "Auto-remove New badge", set duration to 21 days. Applies to all future items.
