WordPress Price Comparison Plugin for Billiger.de and Geizhals.de

We’re excited to introduce two new Content Egg modules: Billiger.de and Geizhals.de.

These integrations make it easier to build price comparison, deal, and product-focused affiliate websites in WordPress. Instead of collecting offers from individual merchants one by one, you can import a full price comparison list for a product in a single request.

For affiliate marketers, niche site owners, and comparison website publishers, this means richer product pages, better buying guidance for visitors, and more opportunities to earn from outgoing clicks.

Why these modules matter

Price comparison content helps users make faster, more confident purchase decisions.

Instead of sending visitors to a single store, you can show several buying options, compare prices, highlight availability, and make it easier for users to choose the best offer.

This creates several advantages:

• better user experience
• more complete product pages
• more click opportunities
• easier content maintenance
• more useful product reviews and roundups

Another important benefit is the monetization model. Both affiliate programs are based on forwarded clicks, not completed sales. That means publishers can earn when users click through to a merchant, without depending entirely on whether the final purchase is completed.

Billiger.de module overview

The new Billiger.de module lets you integrate Billiger.de price comparison data directly into your WordPress website through Content Egg.

Billiger.de uses a structured product model:

Base products → Products → Offers

Search results may begin with a broader product entity, but Content Egg converts matched results into real shop offers before saving them. This gives your post practical offer-level data such as:

• price
• merchant
• availability

That makes the module especially useful for building comparison pages based on real store offers, not just generic product references.

Supported Billiger.de search methods

The Billiger.de module supports several search methods:

• keyword search
• direct base product or product URL
• EAN search

Keyword search is useful for product discovery. However, for the most accurate matching, we recommend using a direct product URL or EAN whenever possible. These methods help Content Egg identify the exact product and keep imported offers more consistent during future updates.

Geizhals.de module overview

We’ve also added a new Geizhals.de module for Content Egg.

This module gives you access to Geizhals price comparison data and lets you import a full product offer list directly into your WordPress site.

Like the Billiger.de module, it is useful for affiliate websites, product reviews, comparison pages, product roundups, and deal-focused content.

Supported Geizhals.de search methods

The Geizhals.de module supports three search modes:

• keyword search
• direct product URL search
• EAN search

For matched products, the module returns the full price comparison list, making it easy to display several merchant offers on one product page.

Easy setup in Content Egg

Both modules fit naturally into the existing Content Egg workflow.

After you are approved by the relevant affiliate program, add your API credentials in the module settings and start importing price comparison data into your posts.

For Billiger.de, you need:

• User
• Password

For Geizhals.de, you need:

• User Name
• Secret Key

These credentials are provided by the partner platform after your application is approved.

How to join the affiliate programs

Before using either module, you need to join the corresponding affiliate or publisher program.

For Billiger.de, submit the partner application form and wait for approval.

For Geizhals.de, submit a partnership request through the Geizhals Publisher page. You will usually need to provide your name, email address, website, and a short description of your project.

Once approved, you will receive the access details required to connect the module in Content Egg.

Keep prices and offers updated automatically

A price comparison page is only useful if the offers stay current.

That is why automatic updates are important when working with price comparison data. In the module settings, you can configure the Price Update interval to keep imported prices fresh.

For best results, use EANs or direct product URLs as auto-update keywords. This helps Content Egg re-check the same product during future updates and pull in new offers when they appear on the source platform.

This is especially useful for products where availability changes often or new merchants are added over time.

Best practices for better results

1. Use direct product URLs when possible

If you already know the exact product page, a direct URL usually gives the most accurate result. It reduces ambiguity and improves product matching.

2. Use EAN for stable product matching

EAN is often the best option for identifying a specific product model across future updates.

3. Use keywords for discovery

Keyword search is useful when exploring products or building content around broader product categories. However, it may be less precise than URL or EAN-based matching.

4. Enable regular price updates

Price comparison content becomes more valuable when it stays fresh. A proper update interval helps keep your pages relevant and useful for visitors.

Use cases for Billiger.de and Geizhals.de modules

These integrations can be used for many types of WordPress projects, including:

• product comparison websites
• affiliate niche blogs
• “best price today” pages
• deal and discount posts
• category pages with multiple buying options
• product reviews with price comparison blocks
• buying guides and product roundups

If your site helps users compare products, prices, and merchants, these modules can save time and make your content more useful.

Final thoughts

The new Billiger.de and Geizhals.de modules make Content Egg even more powerful for affiliate marketers and comparison website owners.

Both modules help you import rich price comparison data, display multiple offers, support flexible search methods, and keep prices updated automatically. And because the programs reward forwarded clicks rather than completed sales, they can be especially attractive for publishers with informational and comparison-driven traffic.

Update Content Egg, connect the new modules, and start building more complete price comparison pages for your visitors.
