How to choose
Which recommendation methods fit my use case?
Start with the recommendations you need. Criteo Product Recommendations lists intent-based, contextual and browsing-behavior-based methods, along with upsell and cross-sell suggestions.
Compare the methods a product names with the way you want to guide customers or readers.
Which platforms does it need to run on?
Check the platform marks against the devices and systems you use. The board covers web, Android, iOS, Linux, macOS and API availability.
Adobe Target lists web, Android and iOS; Constructor lists web, Android, iOS and API.
Can I try it before paying?
Check whether a product has a free plan or free trial, and review its paid price when one is listed. Algolia has a free plan; LimeSpot lists a 15-day trial and a starting price of $19.99 per month.
Some pricing is available only on request, as with Adobe Target and Constructor.
Does it offer an API or open-source code?
If you need to connect recommendations to another app, check the API mark and the product’s listed platforms. An API is a way for software to exchange information.
If you need to inspect or change the code, check the open-source mark and the product’s license.
Does it support real-time updates and my delivery channels?
Compare real-time update support and delivery channels with how and where you plan to show recommendations. The board also compares free event limits, which can help when estimating usage under a free tier.
Check product details for the specific channels and limits that matter to your setup.
