How a Single Gluten-Free Filter Can Double Your Customer Reach

A 26-table boutique patisserie in Bursa Nilüfer added one "Gluten-Free" filter to its digital menu and landed 89 new customers by the end of the month. According to Beyond Celiac Foundation, 72% of celiac patients refuse to try a new restaurant if they can't clearly see safe options — and in Türkiye alone that's 600,000 people.

The Invisible Market

The U.S. has 3.1 million diagnosed celiac patients and Türkiye around 600,000. Add 5-7 million non-celiac gluten-sensitive people plus their families, and the audience that actively looks for the GF tag reaches 8-12% of the population.

These guests are the decision-maker of the group. Without a gluten-free option, the entire 3-6 person table walks away. One visible filter equals one average table of four — not just one cover.

Bursa Case Study: 31 Reviews, 89 New Guests

After enabling the gluten-free filter and tagging 6 products, the patisserie's Google Maps reviews containing the keyword "gluten-free" jumped from 0 to 31. Those organic reviews acted as SEO signals — within weeks the place ranked on page 1 for "Bursa gluten free patisserie."

Tracked through the menu order log, 89 new customers came in the first 30 days. Extra monthly revenue: ~$1,300. Setup cost: zero minutes.
