Frequently asked questions
What is the typical cost of implementing an AI recommendation engine?
Costs vary widely by scale and complexity. Cloud-native solutions like Amazon Personalize start under £50/month for small volumes. Mid-market solutions (Algolia, Klaviyo) range £100-500/month. Enterprise platforms (Salesforce, Dynamic Yield) typically require custom contracts starting at several thousand pounds monthly plus implementation fees.
How quickly can recommendations start driving revenue impact?
Cloud-managed solutions often show initial lift within 2-4 weeks once live. Machine learning models typically improve recommendations significantly after 4-8 weeks of behavioural data collection. Enterprise implementations may take 3-6 months to deliver full optimisation across channels.
Which recommendation engine is best for a small e-commerce startup?
Amazon Personalize and Algolia (free tier) offer the lowest barrier to entry with managed infrastructure. Klaviyo suits email-first brands. All three require minimal upfront investment, scale with traffic, and require no dedicated ML engineering team. Start with free tiers to test before committing to paid plans.
