RecoMelon can complement Shopify Search & Discovery, and The Index™ can take on search or collection discovery where the deployment supports it. Replacement should follow a review of current filters, synonyms, merchandising rules, markets and analytics.
What can be tested first?
Start with a visual PDP journey, selected Smart Collection or natural-language search use case and measure it against the existing experience.
Will collection SEO be preserved?
Maintain crawlable collection URLs, useful on-page copy, internal links, canonicals and accessible product content. The implementation should enhance discovery without hiding important catalogue information from search engines.
