How is this top 5 computed?

From 100% public data (SIRENE, INSEE, market data) aggregated by influence area, then ranked by our engine. Output is quantized to 5 potential levels; the exact model composition is not published.

Why an "influence area" rather than a town?

A local shop's clientele extends beyond the town: it comes from surrounding towns gravitating around the same anchor. Analyzing a single town under- or over-estimates the real market.

Does a 5/5 potential guarantee success?

No. The badge measures favorable market conditions at area level, not the quality of a precise location or project. The exact spot, the offer and the execution remain decisive.

Method: an owned ranking, an unpublished formula

Our engine aggregates dozens of signals from public data (facilities, demographics, income, local market momentum) at the scale of each anchor town's influence area. Output is rendered in 5 levels: we publish neither the formula, nor the weights, nor a continuous score — the ranking cannot be artificially "optimized". The full methodology is public.
