E-Commerce Marketing at Kosadel

E-commerce isn’t won with a “good product” alone. It needs the right architecture: acquisition, persuasion, checkout performance and retention. We work in the language that matters: MER/ROAS, CAC, contribution margin, LTV and performance by product category.

When you need it most

When you have traffic but low conversion, when ROAS fluctuates and won’t stabilise, when products don’t appear correctly in Shopping/feeds, or when you want to increase profit without increasing spend.

Sub-services (what we do in practice)

Google Shopping / PMax Merchant Center, feeds, segmentation, scaling.
Meta Catalog / DPA Catalog setup, dynamic ads, remarketing.
Product Feed Optimisation Titles, attributes, categories, rules, diagnostics.
Creative Testing UGC, PDP-first creatives, angles, iterations.

Frequently Asked Questions

ROAS or MER—what do we actually focus on?
ROAS is useful per channel, but MER (total revenue / total marketing spend) shows the true profitability picture. We typically track both, alongside margin/contribution.
What role do product feeds play?
Feeds directly impact performance in Shopping/PMax and catalog ads. Strong titles, attributes, categories, and rules increase relevance, CTR, and conversions.
Do I need CRO, or should I just increase budget?
If conversion/checkout has friction, extra budget simply “buys” more waste. CRO (PDP/cart/checkout) often delivers bigger impact than increasing spend.
Can you also set up email/SMS for e-commerce?
Yes: welcome, abandoned cart, post-purchase, cross-sell, winback and VIP segmentation—so you can increase repeat rate and LTV.
What do you deliver each month?
A KPI report (MER/ROAS/CAC/AOV/CR), a summary of tests (creatives/feeds/offers), changes implemented, and an optimisation/scaling plan.

E-Commerce Marketing by KOSADEL: A Growth System with Cost Control and Measurable Profitability

E-Commerce Marketing is not “running ads.” It’s an end-to-end system that connects product, offer, channels, website experience and data, so revenue increases without profitability collapsing. In e-commerce, real success isn’t measured only by a single campaign’s ROAS, but by whether you build a steady sales pace, healthy margin, and a rising LTV(lifetime value).

At KOSADEL , we approach e-commerce with a performance mindset: clean channel architecture, strong tracking, clear attribution, and a scaling plan with guardrails. E-commerce takes off when acquisition channels (Search / Social / Influencers) “lock in” on a conversion-ready experience and a retention engine (Email/CRM).

What “proper e-commerce marketing” means in practice

Most wasted spend comes from three issues: wrong audience/message, weak product page/checkout, and lack of retention. To avoid these pitfalls, we use a framework that covers:

Core pillars

  • Acquisition: efficient new-customer acquisition with smart budget allocation.
  • CRO: improving conversion rate (product page → checkout → purchase) through data-driven changes.
  • Retention: repeat purchases, upsells, cross-sells, winbacks, and loyalty.
  • Creative & Offer: angles, bundles, value proposition, and assets that hold attention.
  • Measurement: clean tracking and KPIs that reflect profitability (not vanity ROAS only).

How e-commerce marketing fits into the wider service ecosystem

E-commerce is multi-discipline. To ensure consistency and performance, it connects directly to: Search Engine Marketing , Social Media Marketing , SEO , Analytics & CRO , Email Marketing & CRM , Branding & Creative , Video Production / Motion , Influencer / UGC , and proper site build via Web Design .

If the goal is a “profitability plan,” we tie the framework into Marketing Strategy & Consulting , so decisions are grounded in margin, LTV, and realistic scaling targets.

Acquisition that doesn’t break profitability

New-customer acquisition in e-commerce requires balance: generate volume without letting CAC climb out of control. This happens when (a) messaging matches intent, (b) creative rotation is strong, (c) the site converts, and (d) measurement is clean. That’s why acquisition isn’t “one channel,” but a mix: Search demand capture + Social demand creation + UGC trust + SEO longevity.

1) Search: capturing intent and controlling cost

Search channels work when users already look for a product/category/brand. This is where Search Engine Marketing adds value: structured accounts, clean query matching, scalable strategy, and spend control. In parallel, organic coverage through SEO reduces long-term dependency on paid.

2) Paid Social: demand creation and retargeting

Social channels are excellent for demand creation, fast product launches, and retargeting. Social Media Marketing plugs in with a funnel mindset: awareness → consideration → conversion. Paid social performs best with a strong creative engine and continuous angle testing.

3) UGC & Influencers: trust signals that reduce CAC

Influencer / UGC provides social proof and authenticity. In e-commerce, it often unlocks purchase decisions by addressing objections fast: “how does it look?”, “what should I expect?”, “is it worth it?” The right approach isn’t a single post — it’s a system: briefs, hooks, deliverables, usage rights, and paid amplification where needed.

Budget allocation: where money goes to generate profit

Smart allocation is built with rules: protect channels that produce profitable volume, and test new channels with caps so blended CPA stays healthy. In competitive markets, the strategy must be driven by margin and LTV — not a “target ROAS” that looks good but fails on net profit.

The complete acquisition stack

If broader reach is required (especially at scale), we also support Media Buying 360 as complementary coverage.

Conversion rate is the “cheapest” growth lever

In e-commerce, a small uplift in conversion rate can meaningfully increase revenue from the same traffic. Instead of only increasing budget, we build experience optimisation: stronger product pages, clearer CTAs, less checkout friction, and more trust signals. This is the core of Analytics & CRO .

Where purchases are won or lost

  • Product page: clear value, images/video, specs, availability, shipping/returns.
  • Cart: cost transparency, bundle suggestions, fewer “surprises.”
  • Checkout: fewer fields, right payment options, mobile-first, clear steps.
  • Trust: guarantees, policies, reviews, security, consistent brand look.

Web Design built for performance

Design matters when it supports conversion. Web Design for e-commerce must be fast, clean, and purchase-focused: strong information hierarchy, correct mobile experience, and UX that reduces doubts. When creative reinforcement is needed, assets are supported by Branding & Creative and Video Production / Motion .

Measurements that reveal where users get stuck

Optimisation is data-led: funnel drop-offs, device splits, page speed, scroll depth, clicks on key elements, and deep evaluation of the purchase journey. With the right setup, we isolate whether the issue is traffic quality, offer fit, product page clarity, or checkout friction.

SEO & Content as conversion support

E-commerce isn’t only “performance ads.” When SEO and Content Marketing work properly, they build trust before purchase, answer questions (use/sizing/materials/comparisons), and reduce returns. The result is higher conversion and a healthier blended CAC.

Profit in e-commerce is locked in retention

True scale comes when customers come back. If you rely only on new customers, CAC tends to rise over time. Retention increases LTV and allows more aggressive acquisition without harming profitability. That’s why Email Marketing & CRM is a core e-commerce tool.

Automations that generate revenue

  • Welcome series: from first signup to first purchase with proper positioning.
  • Cart abandonment: recover lost purchases with smart incentives.
  • Browse abandonment: reminders for viewed products/categories.
  • Post-purchase: usage guidance, upsell/cross-sell, review requests.
  • Winback: re-activate customers with segmentation and timing.

Reputation & trust: your brand reduces sales cost

Reviews, trust, and customer experience directly impact conversion and CAC. With Reputation Management , we structure review collection/management and strengthen your trust footprint. This pairs with social proof in ads and content that addresses objections.

The creative engine behind retention

Retention isn’t only “discounts.” It needs consistent brand experience and relationship-building content: guides, launches, bundles, seasonal drops. This is powered by Branding & Creative and Video Production / Motion , and structured via Content Marketing .

The rule for healthy scaling

Scaling means increasing spend only when conversion is stable, data is clean, and you have room in margin/LTV. This is where Marketing Strategy & Consulting helps define goals, thresholds, and a realistic growth plan.

Frequently Asked Questions

ROAS is useful, but it can be misleading if it ignores margin, returns, fees, and LTV. We focus on KPIs that reflect true health: blended CAC, contribution margin, and repeat rate. This methodology connects directly with Analytics & CRO and Strategy & Consulting .

Not always. But if the site is slow or checkout has friction, scaling becomes expensive. In that case, improvements via Web Design and conversion work with Analytics & CRO are recommended.

Content reduces objections, increases trust, and supports SEO. With Content Marketing we build guides/collections, and with SEO we cover commercial intent keywords. The result is higher conversion and lower blended CAC.
