Price comparator

A tool that scans your competitors, normalises sheets, ranks offers — for your sector, not generic.

The problem

General comparators (Idealo, Leguide, Google Shopping) are generic. For specialised sectors — pro equipment, local services, custom products, training — they are unusable.

Your customers compare anyway. With incomplete data, unreliable sources, and an experience where your offer is invisible or poorly showcased.

Building a comparator for your sector means becoming the reference — for customers and competitors alike. With SEO traffic and a business model attached.

How it works
Step 01

Sources

Identification of suppliers / competitors to track. Agreements or legal scraping.

Step 02

Normalisation

Unified product sheet whatever the source format (excl./incl. tax, pack size, etc.).

Step 03

Engine

Search, filtering, sorting, comparison, price drop alerts.

Step 04

Monetisation

Vendor sheet, commission, targeted ads, pro subscriptions, white label.

Three variants

Same service, three profiles, three stacks

Vocational training (CPF)

Opaque French market: 30,000 organisations, prices and quality hard to compare.

What it changes
  • Strong SEO positioning: a comparator naturally attracts commercial queries.
  • Several business models possible: commission, pro subscription, advertising, SaaS, white label.
  • Becomes a data source that your customers, journalists and partners will cite.
  • A profitable MVP runs on a VPS — no need for a 50-person team to start.
