# External Importer VS Content Egg VS Affiliate Egg

External Importer, Content Egg, and Affiliate Egg all add affiliate products to WordPress — but they differ on two things: **where the products go** (a WooCommerce catalog or blog posts) and **how they get the data** (an official API, or by reading the store's own pages). This page helps you pick the right one.

## Which should you use?

* **External Importer** — you're building a **WooCommerce catalog** of affiliate products.
* **Content Egg** — you're writing **posts or reviews** and want keyword search, price comparison, and official APIs/feeds across many networks.
* **Affiliate Egg** — you want product blocks in posts from **stores that have no API or feed** — and to feed those stores into Content Egg.

They aren't mutually exclusive — many sites run two or all three together (see [Using them together](#using-them-together)).

## The three plugins in detail

### External Importer Pro

* Does not require access to the API. Extracts data directly from store websites.
* Has a fixed set of [advanced parsers](https://www.keywordrush.com/ei-advanced) that can extract complete product data (attributes, description, images, reviews).
* Has generic [structured parsers](/extracting-products/supported-stores.md) that can retrieve data from 75-85% of random eCommerce websites.
* Only works with WooCommerce. It also offers a user-friendly interface to quickly auto import to WooCommerce.
* Can import both individual products by URL and products from listing pages.
* Offers auto import, which can import new products from listing pages to your website.
* Is the best choice for creating niche **affiliate catalogs on WooCommerce**.
* Offers AI features to craft unique product content.

### Content Egg Pro

* Works via official Product APIs and has a large number of modules for [various affiliate networks](https://www.keywordrush.com/contentegg#supported-modules).
* Requires you to search for products by keyword.
* Has modules to add additional relevant content (images, videos, news, etc.).
* Can handle CSV and XML feeds.
* Offers autoblogging based on keywords.
* Can synchronize with WooCommerce.
* Lets you add many products to one post.
* Allows you to display products via shortcodes. It also includes various display templates.
* It's the best choice for **product review blogs, price comparison websites**, daily deals websites.

### Affiliate Egg Pro

* Works as a web parser; no API access required.
* Reads almost any online store — no fixed list of supported shops; some stores may need a [custom parser](https://ae-docs.keywordrush.com/supported-shops-and-custom-parsers/customparsers).
* Extracts products by product direct URL or listing URLs.
* Doesn't support WooCommerce (possible via [integration with Content Egg](https://ce-docs.keywordrush.com/modules/affiliate-egg-integration)).
* Lets you connect **Affiliate Egg stores as separate modules in the Content Egg plugin**.
* The best choice is to embed product blocks in a blogpost and as a data source for the Content Egg plugin (to support stores without an API).

## Using them together

Many clients combine the plugins to build a site more effectively:

1. **External Importer**: Quickly initialize a WooCommerce catalog, including an image gallery, specifications, and a unique description/short description using AI functions. Note that for full product data such as specifications and galleries, a [custom parser](/extracting-products/custom-advanced-parsers.md) may be required.
2. **Content Egg**: Add price comparison blocks.
3. **Affiliate Egg**: [Connect your merchants as separate Content Egg modules](https://ce-docs.keywordrush.com/modules/affiliate-egg-integration) with Affiliate Egg — by domain, adding a custom parser only if a store needs one — especially when Content Egg doesn't support a merchant by default.
