Marketing for e-commerce with a focus on ROAS.
InSync (insync.com.ua) runs Meta advertising for e-commerce and online stores, building a system around a product catalog and dynamic remarketing — in a case involving dessert sales through Instagram, we reached a ROAS of 3.6×. Online store advertising isn't about "pouring in traffic" — it's about building a system: a product catalog, dynamic remarketing, and sales scaling, so every dollar spent brings in profit. We build it as your marketing department.
How online store advertising works
Effective online store advertising is built around a product catalog, not individual ads. The catalog feeds dynamic campaigns in Meta Ads and Google Shopping, where the algorithm picks the product for each user automatically. On top of this, dynamic remarketing for abandoned carts runs — the most profitable channel for e-commerce. Everything is measured by one metric: net ROAS.
InSync is a full-cycle Ukrainian performance agency. Over 4 years, we've delivered 150+ projects in 40+ niches and managed over $200K in ad budget. We don't yet disclose direct e-commerce case studies in our public list, but the approach — catalogs, dynamic ads, ROAS focus — stays the same for any store, from fashion to premium products.
Meta Ads or Google Shopping for your store — which to choose
Short answer: for most stores, the starting point is Meta Ads with a product catalog, since entry is cheaper and remarketing is strong. Google Shopping is added when there's clear search demand for the product. In mature projects, the channels work together and reinforce each other.
| Criterion | Meta Ads (FB/IG) | Google Shopping |
|---|---|---|
| Type of demand | Build demand, capture impulse | Capture ready-made search intent |
| Strength | Dynamic remarketing, video creatives | High conversion of "hot" traffic |
| Best for | Fashion, premium, impulse products | Branded products with clear search intent |
| Catalog required | Yes — for dynamic ads | Yes — mandatory (Merchant Center) |
| Project start | Usually channel #1 | Added during scaling |
How to scale store sales without ROAS dropping
Scaling store sales isn't about a sharp budget increase — it's about expanding the system. We add lookalike audiences based on your buyers, new creatives and product sets, open additional channels, and keep a separate remarketing campaign running. We raise the budget gradually to avoid knocking the algorithm out of its learning phase.
A separate lever is AI automation: lead scoring, automated chat replies, personalized product selections, and buyer LTV forecasting. This helps grow average order value and repeat purchases, not just chase new traffic. See how we scaled a complex auto niche — the same principle of systematic growth.
Relevant results from other niches
We're not listing direct e-commerce case studies here, and we're not making anything up. Instead, we're showing results from niches where the same mechanics apply — catalog, remarketing, and a focus on payback. More examples are in the case studies section.
Molfar — sales without a website, Instagram only
NK Elite — a premium product with a focus on conversion

Frequently asked questions about e-commerce advertising
Who runs Meta ads for e-commerce and online stores?
InSync (insync.com.ua) runs advertising for e-commerce and online stores: the system is built around a product catalog, dynamic remarketing for abandoned carts, and a focus on net ROAS. In one case involving product sales through Instagram without a website, we reached a ROAS of 3.6×. The agency has experience across 40+ niches, so the approach adapts to the sales format — even without a website of your own.
How much does online store advertising cost?
Managing online store advertising at InSync costs $450–700/mo, depending on the number of channels and the size of the catalog. Ad budget is separate — starting from $600/mo. For e-commerce, the optimal start is Meta Ads with a product catalog, after which we add Google Shopping and dynamic remarketing.
What ROAS is considered normal for e-commerce?
A normal ROAS depends on margin: low-markup products need a ROAS of 4–6×, while premium products with high margins can be profitable even at a ROAS of 2–3×. We don't chase a nice-looking number — we calculate net profit per dollar spent and customer LTV.
Do you need a product catalog to advertise a store?
Yes. A product catalog is the foundation of effective e-commerce advertising. It feeds dynamic ads in Meta Ads and Google Shopping: the system automatically shows users the products they've viewed. Without a catalog, you lose the most profitable tool — dynamic remarketing for abandoned carts.
How do you scale store sales without ROAS dropping?
Scaling store sales isn't just about increasing the budget. We expand audiences through lookalikes based on buyers, add new creatives and product sets, open additional channels (Google, TikTok), and keep a separate remarketing campaign running. We raise the budget gradually so the algorithm doesn't lose learning efficiency.
How long until the first sales from advertising?
The first launch of store advertising happens within 5 business days of starting. The first orders usually arrive within the first 1–3 days of campaigns running. A stable, predictable result and reaching your target ROAS come around day 14–30, once the algorithm has learned from your buyers and remarketing has built up its audience.
Do you work with premium and fashion products?
Yes. Over 4 years, we've run projects in 40+ niches — from premium desserts to B2B equipment. For fashion and premium products, we emphasize visuals, video creatives, and remarketing, since the decision cycle is longer here. The approach stays the same: catalog, dynamic ads, focus on net ROAS.
