Our Open Catalogue contains all offers that have not been allocated to an idealo product. Quite often, the relevant product type is not featured in our idealo product catalogue, or it could be that an allocation to an idealo product was not possible due to missing identifiers.
To ensure that these offers are still available to idealo's users, idealo has an Open Catalogue. All offers provided to idealo that have been allocated to a category can be found here by navigating through the categories or using the search function.
In terms of how search results are sorted, the exact search term that the user types in plays a vital role. To this end, our editing team sets up filters that assist the idealo user in narrowing down their search. Additionally, individual offers in the Open Catalogue that have not been allocated to an idealo product are grouped together on the basis of matching characteristics (e.g. barcode numbers). These groups of offers are very similar to an idealo product, enabling users to compare several identical offers even if these have not been allocated to a product.
For an optimal listing, it is therefore important for you, as a retailer, to provide idealo with identifiers, precise offer names, high-quality pictures and as many category-specific attributes (brands, colours, sizes, etc.) as possible.
