How to compare e-commerce agencies in CEE

Start with the constraint in your store. A migration, an unreliable product feed, weak organic visibility and unprofitable paid acquisition require different work: a migration needs redirects, checkout testing and rollback, a feed needs an owner who resolves failures. Ask agencies to price the same scope before comparing their proposals.

What the public sources establish

An agency's website shows what it sells, not how its client accounts perform. Case studies and directory reviews show selected work: use them to find reference clients to call. This guide does not audit client accounts or rank delivery quality. An agency also does not need its own software to measure customer value; ask instead for a sample reconciliation between store and ad reports.

On the pages we could open on 24 September 2026, aNavigator describes Amazon advertising, Blu Mint lists e-commerce SEO and Shopify development, and widoczni and Growwwise publish search services. Follow the source links and ask each agency to confirm the platform, country and team you need.

Agencies to investigate

The links below keep the shortlist from our earlier regional research, in alphabetical order. Being listed makes an agency worth a call; it does not mean we endorse its current capacity or results. When we checked on 24 September 2026, some sites could not be retrieved reliably, so we left out the earlier ratings and prices and make no claim that any agency lacks a service.

Compare the work, not the headline metric

Separate marketplace work from work on your own store. Ask which account and customer data remain available to you when the contract ends. A case about Amazon advertising does not by itself demonstrate a Shopify migration capability.

Compare total cost and responsibility

Request implementation, ongoing fees, media spend, creative production, software and additional development as separate lines. Confirm currency, tax, minimum term and notice period. A directory's minimum project value is not a quote for your store.

Specify who can edit checkout, who approves promotions and who handles a feed or payment failure. Ask to meet the people assigned to the work. Public team size does not establish the capacity reserved for you.

Decide from the same brief

Give the shortlisted agencies the same anonymised business context: catalogue, margins, order and return definitions, platforms, markets and constraints. Ask each to identify what it can verify before proposing a target.

Use contribution margin to define the amount available for acquisition. Compare POAS and ROAS with consistent cost and attribution definitions. Neither a high review count nor a promised ROAS replaces that work.

Our relationship with Zest

Zest is our agency, and Loyalz is our product. We have a commercial interest in both. That relationship does not establish that Zest is a better fit than the other candidates. Evaluate its proposed team, deliverables, measurement and price against the same brief.

Ownership of a measurement tool is one implementation option, not a prerequisite for measuring customer value. Ask any supplier to demonstrate the relevant report on suitably anonymised data. Confirm current commercial terms directly; this article is not a quote.

Sources and limits

We checked the nine linked websites on 24 September 2026, where they loaded. Each one is the agency's own description of its offer: a primary source for what it sells, not independent evidence of client results. Nine agencies are a regional selection, not a market survey. If a website does not mention a service, we do not conclude that the agency lacks it.

See the other agency selection guides for a brief suited to the work you need.
