Seller Interactive

Based in Markham, Canada, Seller Interactive is an agency founded in 2019 that concentrates on Amazon and Walmart marketplace growth, working with a team of 11-50 people to serve brands looking to launch, scale, or recover their online store performance. Its client base spans sellers at different stages, from those just starting on Amazon to established brands facing stalled sales or advertising fatigue, with case studies referencing categories such as home and kitchen products. The agency positions itself as a partner for sellers who need ongoing account oversight rather than one-off fixes, tracking Amazon's policy and algorithm changes as part of its service delivery. Services cover full Amazon and Walmart account management, SEO, PPC management, listing optimization, brand protection, suspension appeal and reinstatement support, reimbursement and refund handling, Amazon DSP, product launch support, account health monitoring, and storefront design. Additional performance marketing covers TikTok, Meta, and Google ads. On the SEO and listing side, the agency describes working on keyword-rich content and backend optimization to improve product rankings, alongside product page copy and visual optimization intended to increase click-through and conversion. PPC work is described as data-driven, aimed at reducing wasted ad spend while improving return on investment. The agency also references A+ content and write-up support to strengthen brand presentation for Sponsored Products campaigns, and frames its approach around using sales and customer behavior data to identify bottlenecks and adjust strategy for continued account growth.
