UI & UX Design for Marketplaces and Aggregators

Two-sided interfaces for buyers and sellers, search and filtering, trust and review display, and seller onboarding.

Last revised

What marketplaces and aggregators are dealing with

The situation: Two-sided growth, enormous catalogs of other people's data, and quality control you only partly own. Image normalization at scale, structured data, search and faceted navigation, and performance under catalog growth.

Timing and approvals

When the work happens
Continuous, with the balance of investment shifting between the two sides as the market matures.
Who signs it off
A product lead who will look at seller retention as well as buyer conversion.

The constraint that shapes it

Search and filtering carry the experience at catalog scale, and relevance is a product problem rather than a visual one.

The INFORM Consumers Act imposes seller verification and disclosure duties on online marketplaces, and the FTC polices review authenticity. Faceted navigation is usually the biggest technical SEO problem in the sector. This is a practical note, not legal advice.

What goes wrong, and what to do instead

Avoid: Designing for the buyer only. A marketplace fails on the supply side first, and seller tools are usually the neglected half.

What it costs
