SEO title: Mont Blanc Boutique Cannes luxury — WeAdU

Client

Mont Blanc Boutique Cannes (montblanc-boutique-cannes.com) ran Google Ads with WeAdU. The comparison uses two dated windows — January 1–March 31, 2025 vs April 15–July 15, 2025. This is the Cannes boutique on the Croisette, a separate account from Montblanc Bordeaux.

Challenge

Two pressures had to be held at once:

Name the city: Cannes — Festival traffic and Croisette walk-ins are a Cannes calendar. Treating this as a generic Montblanc file would erase the city.
Haute horlogerie, not a pen gift set — Exceptional watches and writing instruments on the Croisette are the SKUs. Entry-level gift queries had to stay out of the Cannes account.

Approach

We raised budget around the Cannes Festival and the summer peak, bought Search on haute horlogerie and exceptional pieces, and pinned location extensions on the Croisette. The city is Cannes; this is not the Bordeaux boutique.

Results

Comparing January 1–March 31, 2025 vs April 15–July 15, 2025, WeAdU delivered a +162.22% increase in orders — 45.00 → 118.00 — for Mont Blanc Boutique Cannes. Against the previous period, the account also delivered:
