Send Comparer the products worth showing.

Comparer.fr is a French price and product comparison website: shoppers browse and filter products across categories such as electronics, home and kitchen, furniture, office supplies, fashion and more, then click through to the listed merchant's own store to complete the purchase. It is operated by Compare Group, a Dutch price-comparison holding company founded in 1999 that also runs Vergelijk.nl and Vergelijk.be (Netherlands/Belgium), Comparer.be (Belgium), Vertaa.fi (Finland), BesteKauf.de (Germany) and comparable sites in Sweden, Denmark, Norway, Austria, Italy, Spain and Portugal.

The Comparer.fr brand originally launched in 2009, was discontinued around 2017, and was relaunched by Compare Group in May 2025 as the group's re-entry into the French market. According to its own "About" page, Comparer.fr positions itself as a neutral comparator with no bidding system for placement, meaning listed merchants are not meant to buy a higher position by paying more.

Comparer.fr gives French shoppers another place to compare your prices against competitors at the exact moment they're deciding where to buy, alongside other French and pan-European comparators such as 123comparer, Idealo or Leguide. For merchants already running feeds to those larger comparators, adding Comparer.fr is typically a low-effort way to pick up incremental, price-motivated traffic.

Because Comparer.fr runs on Compare Group's shared merchant infrastructure -- the same backend used for its sister sites in the Netherlands, Belgium, Finland, Germany and elsewhere -- a well-structured feed built for Comparer.fr can also serve as the starting point for reaching those other national sites later, without rebuilding your feed logic from scratch.

Per Comparer.fr's own partner registration page, the site works on a pay-per-click (CPC) basis: you are billed for visitors it sends through to your store, and each month you receive an invoice showing the number of visitors (clicks) and the CPC rate applied. Its "About" page separately states that Comparer.fr aims to compare offers "as neutrally as possible," with no bidding system -- so, as described by Comparer.fr itself, paying a higher CPC is not presented as a way to buy a better position in results.

The same partner page states that Comparer.fr refreshes its product database daily, which is the mechanism that determines how quickly a price, stock or content change in your feed shows up on the live site (more on this under "How often should the feed update?" below).

According to Comparer.fr's partner registration page, your product catalog must be published as a CSV, TXT or XML file hosted at a stable, static URL on your own server (its own illustrative example resembles www.votreboutique.fr/comparer.csv). Once submitted, Comparer.fr's integration team reviews and connects the feed, with products going live "within a few days" of integration, per that page.

Comparer.fr sits on Compare Group's shared merchant platform. Compare Group's own published Datafeed manual -- the same document that governs feeds for its Dutch, Belgian, Finnish and German sites -- references a dedicated French-language product classification file (classifications+FR.txt, hosted at sc.vergelijk.nl). That's direct evidence Comparer.fr draws on the same underlying feed schema as the rest of the group, rather than a one-off, France-only format, even though comparer.fr's own public partner page describes onboarding in simpler terms.

Comparer.fr's own partner page does not publish an itemized field list; it describes submission at a higher level (a CSV/TXT/XML catalog at a stable URL). The table below reflects the field set documented in Compare Group's shared Datafeed manual, which the France-specific classification file confirms Comparer.fr draws on. Treat these as the group's standard schema rather than a list confirmed to be published under the Comparer.fr brand specifically.

Feedance is not an official Comparer.fr or Compare Group partner; the steps below describe a general process for producing a feed that fits Comparer.fr's documented submission requirements.

1. Apply as a partner through Comparer.fr's "Devenir partenaire" registration page, providing the store details it requests -- payment methods, guarantees/returns policy, shipping methods and customer service contact information.
2. In Feedance, build a feed mapping your catalog to at least the core fields Comparer.fr's process implies: product name, price, image, deep link, category and stock status, plus brand and an EAN/SKU identifier where available.
3. Publish the feed as CSV, TXT or XML at a stable, externally accessible URL, matching the file location Comparer.fr's integration team asks you to provide during registration.
4. Submit that feed URL as part of your partner application.
5. Allow a few days for Comparer.fr's integration team to review and connect the feed, as described on its partner page, before offers go live.
6. Once live, keep the feed accurate day to day -- Comparer.fr states it refreshes its database daily, and you're billed per click, so stale prices or out-of-stock items sent through as available directly cost you money.

Comparer.fr's own partner page states that it refreshes its product database daily. That means once your feed file is connected, changes you publish to it -- price changes, stock status, new or discontinued products -- are expected to be picked up on roughly a daily cycle rather than instantly. Given the CPC billing model, keeping price and availability current at least daily matters directly for your ad spend: a shopper who clicks through to a price or an out-of-stock item that's no longer accurate is a paid click with no chance of converting. Feedance can regenerate and publish your feed file on a fixed schedule so the file waiting at your published URL is always current ahead of Comparer.fr's next daily pull.

Comparer.fr has not published a public list of specific error codes or rejection messages. The issues below are drawn from the validation rules documented in Compare Group's shared Datafeed manual (which, per the French classification file referenced in that manual, also governs Comparer.fr), so treat them as platform-level risk areas rather than confirmed Comparer.fr error text:

1. Feed not reachable at the agreed URL. Since Comparer.fr pulls from a URL on your own server, moving or renaming the file without updating Comparer.fr breaks the daily refresh silently.
2. Invalid or mismatched product identifiers. Malformed EAN codes or SKU values that don't match your actual product can prevent correct matching.
3. Category mismatch. Mapping products to overly broad or incorrect categories, instead of Comparer.fr's most specific available category level, reduces how easily shoppers find your offers.
4. Inconsistent or changing offer IDs. Reusing or shifting a product's identifier between feed updates can cause it to be treated as a new or duplicate listing.
5. Non-compliant images. Images carrying your shop's logo, price text or promotional overlays are a documented issue across Compare Group's sites and can keep a listing from displaying properly.

These are general best practices for feed-driven price comparison sites, not claims specific to Comparer.fr beyond what is cited above:

1. Keep price and stock status accurate on at least a daily cadence, matching Comparer.fr's own refresh cycle, since you pay per click regardless of whether the visitor can actually buy.
2. Use the most specific category available for each product rather than a broad parent category, to improve matching and discoverability.
3. Populate brand and an identifier (EAN or SKU) on every product, since these are the fields platforms in the Compare Group network use for matching.
4. Use clean product images without your logo, pricing or promotional text overlaid, since overlay text is a common cause of listing issues across comparison platforms.
5. Write plain, specific product titles and descriptions rather than promotional copy, since comparison sites are optimized for shoppers scanning and comparing facts quickly.

What file formats does Comparer.fr accept?
Per its partner registration page, CSV, TXT or XML, hosted at a stable URL on your own server.

How much does it cost to list on Comparer.fr?
Its partner page describes a pay-per-click model: you receive a monthly invoice showing the number of visitors sent to your store and the CPC rate applied. No fixed rate card was publicly available to verify.

How long until my products go live?
Comparer.fr's partner page states products are integrated and published "within a few days" once your feed is submitted and reviewed.

Does paying more per click get better placement?
According to Comparer.fr's own "About" page, it aims to compare offers as neutrally as possible with no bidding system for placement.

How often is my feed re-read?
Comparer.fr states it refreshes its product database daily.

Is Comparer.fr the same platform as Comparer.be or BesteKauf.de?
They are sister sites under the same owner, Compare Group, and appear to share merchant feed infrastructure, but each operates as a distinct national site with its own registration and terms.

Comparer.fr is a French price and product comparison website. Shoppers browse and filter products in categories such as electronics, home and kitchen, furniture, office supplies and fashion, compare offers from different merchants and then click through to the merchant's own store to complete the purchase.

The site is operated by Compare Group, a Dutch price-comparison company that runs similar comparison sites in several European countries, including the Netherlands, Belgium and Germany. Comparer.fr presents itself as a neutral comparator, without a bidding system that lets merchants buy a higher position.

Merchants apply as partners and supply their catalog as a CSV, TXT or XML file hosted at a stable URL on their own server. Comparer.fr refreshes its product database daily from that file and works on a pay-per-click basis: you are billed for the visitors it sends to your store, with a monthly invoice.

Because shoppers on Comparer.fr compare prices at the moment they decide where to buy, accurate feed data is essential. Correct prices, stock status, shipping costs, images and identifiers such as EANs help your products match the right listings, and they prevent paid clicks on offers that are out of date.
