# Billigerde module

#### Introduction

The Content Egg **Billiger.de module** lets you integrate product offers from Billiger.de into your website.

Billiger.de is structured around three entity types:

**Base products → Products → Offers**

When you search by keyword, Billiger.de may return either **base products** or **products**, depending on the selected search settings. Content Egg then resolves these results into actual **shop offers**, so the saved entries always include offer-specific information such as price, merchant, and availability.

#### How to Join the Affiliate Program

#### Search Result Type Setting

In the module settings, you can choose the default **Search result type**.

This setting determines which Billiger.de entity type is searched first when using keyword-based search. Regardless of whether the initial match is a base product or a product, Content Egg always converts the result into a concrete shop offer before saving it.

#### Best Practice

We recommend searching by direct **base product** or **product** URL whenever possible, as this usually provides the most accurate match.

Supported URL formats include URLs containing **`baseproducts`** or **`products`**, for example:

* `https://www.billiger.de/`**`baseproducts`**`/110057-apple-macbook-air-m4-2025`
* `https://www.billiger.de/`**`products`**`/5442274125-sony-playstation-5-slim-digital-edition-fortnite-flowering-chaos`

#### EAN Search

The module also supports search by **EAN**.
