Amazon and marketplace advertising, content and account management

Mercatus is a UK marketplace agency that helps consumer brands launch and grow on Amazon and other online marketplaces. It works with both Amazon sellers and vendors, and positions itself as a full-service partner rather than a single-channel specialist.

Its work covers marketplace advertising and search, listing and content optimisation to help products rank and convert, and day-to-day account management. The team also advises on logistics and operations and keeps watch over account health and compliance, areas that can quietly hold back sales on marketplaces if left unchecked.

New relationships usually begin with a free account audit, presented as a traffic-light report that looks at performance, stock availability, Buy Box ownership, sales rank, advertising and competitors. Clients are then assigned a dedicated team that operates as an extension of their own staff, handling the marketplace side of the business on their behalf.
