Price comparison in affiliate marketing refers to the use of comparison sites that aggregate different offers and prices for products and display the best deal to users.

These sites are an important publisher segment for online shops (advertisers), as they direct potential customers to the most attractive offers. Price comparison sites rely on product data feeds, which automatically provide up-to-date product information, prices, and availability.

Without advertisers supplying such a feed, cooperation with price comparison sites isn’t possible—meaning valuable sales opportunities are lost. At selecdoo, price comparison sites are highlighted as an effective tool in affiliate marketing because they increase product visibility and strengthen competitive advantage through transparent pricing.

The integration of product data feeds is therefore a fundamental requirement for successfully incorporating price comparison sites into an affiliate strategy.
