# Price comparison websites

Build a price comparison website with Content Egg: one page per product, offers from many shops matched by EAN, the lowest price on top. Do it by hand or let an AI agent do the matching.

A price comparison page shows **one product** with its offers from several shops, the cheapest first. Content Egg finds the same product in your modules, keeps the prices up to date and shows them with a comparison template.

### How it works

* **One page = one product**, and one variant of it: "iPhone 15 128 GB Black", not "iPhone 15".
* **The EAN finds the same product in every shop.** A keyword search also returns accessories and other models; a search by EAN (the barcode number, also called GTIN) does not.
* **Prices update by themselves.** Content Egg refreshes the offers' prices and stock on a schedule. The page always shows the current lowest price.

### Posts or WooCommerce products

Use **WooCommerce products**. Each comparison page becomes a product in your shop: the product shows the lowest price, it can be filtered and sorted in your catalog, and its **Buy** button goes to the cheapest shop. Posts work too, for example for a review with a price list.

### Two ways to build the pages

|                              | By hand                                 | With an AI agent                                      |
| ---------------------------- | --------------------------------------- | ----------------------------------------------------- |
| **You**                      | search, pick the offers, add the blocks | describe the product, answer questions, approve       |
| **Matching the offers**      | you read the titles                     | the agent checks every offer and asks you when unsure |
| **Variants (128 / 256 GB…)** | separate pages                          | separate pages, linked with a variant switcher        |
| **Needs**                    | Content Egg                             | Content Egg Pro and a connected AI agent              |
