In 2025, relying on a single marketplace is a single point of failure. Amazon algorithm changes can cut your organic rankings overnight. Shopify alone limits your discovery surface. TikTok Shop is creating category winners in 60 days. Mezvic's eCommerce management services deploy your products across every platform where your buyers are already shopping — with platform-specific keyword strategies, advertising structures, and listing architectures engineered for each algorithm. One agency, every marketplace, maximum revenue.
Every Mezvic eCommerce management service is run by certified platform specialists — not generalists. Each platform has its own algorithm, its own advertising structure, and its own optimization requirements. We master all of them.
The world's largest product search engine. We handle listing optimization, A+ content, Sponsored Products/Brands/Display PPC, FBA logistics, brand registry, and review strategy — everything needed to rank, convert, and scale on Amazon.

Start Selling on Walmart →Businesses selling on 3+ platforms generate 2–4× more revenue than single-platform sellers. Each platform reaches a different audience segment with different buying behavior. Amazon captures intent-driven search. TikTok Shop creates discovery demand. Shopify builds brand loyalty and repeat purchase. Etsy reaches premium niche buyers. Together, they compound.
Book free multi-platform strategy call →Amazon is the world's largest product search engine — more product searches begin on Amazon than on Google. With over 310 million active customers, it is both the most lucrative eCommerce channel in existence and the most competitive. The difference between a product generating $5,000/month and $50,000/month is rarely the product itself — it is the quality of the Amazon optimization strategy behind it.
Ranking on Amazon's A9/A10 algorithm requires a precise combination of keyword-rich listing copy, A+ Content, a PPC campaign structure that maintains target ACoS, a review strategy that builds social proof, and inventory management that never runs out of stock. Mezvic's Amazon FBA management services cover every dimension.
Shopify powers over 4.5 million online stores — but a Shopify store is only as powerful as the strategy, design, and optimization behind it. The default Shopify experience converts at roughly 1.5%. Mezvic-optimized Shopify stores consistently achieve 4–8% conversion rates through systematic CRO, strategic app integration, and campaign support.
Whether you need a new store built from scratch or an existing store optimized and managed, our Shopify development services, Shopify SEO services, and eCommerce management cover every growth lever — from initial design to ongoing revenue optimization.
TikTok Shop has grown from a novelty to a multi-billion-dollar commerce channel in under 3 years. The platform's unique advantage is discovery-driven purchasing: users are not searching for products — they are discovering them through content and buying impulsively when a product is presented compellingly. Products that go viral can sell out their entire inventory in 24 hours.
For brands positioned correctly, TikTok Shop represents a blue-ocean opportunity. Unlike Amazon where you compete on keyword rankings, TikTok Shop rewards content quality, creator relationships, and live shopping execution. Mezvic's TikTok Shop management services cover every dimension of this unique commerce channel.
eBay has 134 million active global buyers and remains one of the highest-converting eCommerce platforms for used goods, collectibles, and unique products. The Cassini search algorithm is significantly different from Amazon and Google — it rewards complete item specifics, competitive pricing, and seller reputation metrics above all else.
Our eBay store management services include full listing optimization tuned to Cassini's ranking factors, Promoted Listings campaign management, pricing strategy, customer service management, and feedback strategy — consistently growing our clients' eBay revenue by 2–4× within 90 days of engagement.
Etsy has 95 million active buyers specifically looking for handmade, vintage, digital, and custom products — a highly targeted audience willing to pay premium prices for quality items. The Etsy search algorithm rewards keyword-optimized titles and tags, strong conversion rates, competitive pricing, and seller performance metrics.
Most Etsy sellers leave significant revenue on the table through under-optimized listings, poor tag usage, no Etsy Ads strategy, and seasonal promotion gaps. Mezvic's Etsy SEO services and store management systematically close every gap — we have helped Etsy sellers triple revenue within 90 days through keyword strategy alone.
WooCommerce is the world's most customizable eCommerce platform — powering over 29% of all online stores. Unlike Shopify, it has no per-transaction fees, no platform lock-in, and no restrictions on functionality. For businesses that want complete control over their store experience and data, WooCommerce on WordPress is the answer.
Our WooCommerce development services cover everything from fresh store builds to complex migrations, with full WooCommerce SEO services, speed optimization, and security hardening included as standard on every project.
Walmart Marketplace is the most underutilized major eCommerce channel in the United States. While 80% of Amazon sellers compete against millions of listings, Walmart Marketplace has far fewer approved sellers, significantly less competition per category, and a buyer base of 120 million monthly visitors who trust the Walmart brand implicitly.
Walmart has strict seller approval requirements — account health metrics, compliance standards, and fulfillment expectations must be maintained carefully. Mezvic's Walmart marketplace management handles everything from the initial application through to ongoing listing optimization, Walmart Connect advertising, and WFS fulfillment management.
