Capabilities
Paid Media Built Around Ecommerce Revenue
Every campaign we run is structured around revenue and ROAS — not impressions, sessions, or cost-per-click benchmarks that do not connect to your bottom line.
Google Shopping Ads Management
We build and manage Shopping campaigns from product feed optimisation to bid strategy. A broken feed wastes more budget than any poorly written ad — so we fix the data layer first, then build the campaign architecture on top of it.
Performance Max for Ecommerce
Performance Max campaigns require careful asset group organisation and audience signal strategy to deliver profitable results. We structure PMax around your product margins and buying intent signals rather than letting Google's automation spend on low-value placements unchecked.
Dynamic Retargeting Ads
We set up product-level dynamic retargeting across Google Display, Meta, and TikTok — serving ads that show the exact products a visitor viewed or added to their cart. Dynamic retargeting ads consistently outperform static retargeting by showing relevant inventory to warm audiences at the right moment.
Meta (Facebook & Instagram) Ads
We run Advantage+ Shopping Campaigns alongside manual audience builds — testing creative formats, product sets, and offer angles to find combinations that deliver consistent ROAS. Meta's strength for ecommerce is prospecting and post-purchase LTV campaigns, and we structure accounts accordingly.
Shopify PPC Services
Our Shopify PPC services include pixel setup verification, Google and Meta feed sync, conversion tracking via Shopify's native analytics and GA4, and campaign structures that account for Shopify's attribution model. We also integrate with Shopify apps like Triple Whale or Northbeam on request.
Ecommerce PPC Analytics & Attribution
We set up revenue-connected reporting that shows actual purchase value from each campaign — not just conversion counts. You receive a weekly revenue breakdown and a bi-weekly ROAS report segmented by product category, campaign type, and audience segment.
CHANNELS
Every Platform That Moves Ecommerce Revenue
We manage spend on platforms proven to drive ecommerce purchases — with channel-specific strategies, not copy-pasted campaign structures.
Google & YouTube
Shopping, Search, Display, Performance Max, and YouTube for ecommerce — managed as a coordinated system with shared audience lists and product feed integration.
Meta (Facebook & Instagram)
Prospecting, retargeting, and Advantage+ Shopping campaigns with creative testing built into every engagement. Meta drives both new customer acquisition and post-purchase upsell sequences.
TikTok Ads
Product-led creative for stores targeting under-35 demographics. We manage TikTok Shopping, Video Shopping Ads, and catalogue-based dynamic ads for brands where TikTok users match the customer profile.
Microsoft / Bing Shopping
Bing Shopping is consistently underused by ecommerce advertisers, meaning lower CPCs and less auction competition. We import and adapt Google Shopping campaigns and manage them as a separate revenue channel.
ONBOARDING ROADMAP
Our 4-Step Ecommerce PPC Audit & Onboarding
We do not start spending until we have completed a structured account review. Here is exactly what that process looks like — every deliverable listed, no vague promises.
Product Feed & Merchant Centre Audit
A broken or incomplete product feed is the most common reason Shopping campaigns underperform. We audit every feed attribute before touching campaign settings.
- Feed completeness review (titles, descriptions, GTINs)
- Disapproved products diagnosis
- Custom label strategy for margin segmentation
- Feed sync verification (Shopify, WooCommerce, or custom)
- Merchant Centre policy compliance check
Tracking & Attribution Validation
We verify that every conversion event records accurate purchase value — not just conversion count — before making any optimisation decisions based on the data.
- GA4 ecommerce event validation
- Google Ads & Meta pixel purchase event test
- Revenue value passing confirmation
- Shopify attribution model documentation
- Third-party attribution tool integration (if applicable)
Campaign Architecture Rebuild or Review
We assess existing campaign structure for budget waste, audience overlap, and missing product coverage — then rebuild or restructure based on findings.
- Campaign segmentation by product margin and intent
- Search term and negative keyword audit
- Audience list review (remarketing, RLSA, LTV)
- Bid strategy alignment to ROAS targets
- PMax asset group and audience signal review
Revenue Reporting Setup & Optimisation Cadence
We build a weekly revenue report from day one and agree a fortnightly optimisation and review rhythm that keeps your team informed without requiring you to interpret raw platform data.
- Weekly revenue-by-campaign report
- Fortnightly strategy call with your team
- Monthly creative and offer review
- Quarterly ROAS target reset and budget planning
- Live dashboard access (Looker Studio or equivalent)
Shopify Specialisation
Shopify PPC Services Built for How Shopify Actually Works
Most PPC agencies apply generic campaign setups to Shopify stores without accounting for Shopify's attribution model, product feed quirks, or the difference between Shopify's reported conversions and actual revenue.
Our Shopify PPC services start with the data layer — verifying that pixels, GA4 events, and the Google & YouTube app are passing accurate purchase values — before making a single bid change.
- Google & YouTube Shopify app setup and verification
- Meta Pixel and Conversions API (CAPI) configuration
- GA4 ecommerce schema validation for accurate revenue reporting
- Product feed title and description optimisation for Shopping relevance
- Shopify Markets compatibility for international campaign targeting
- Integration with Triple Whale, Northbeam, or Polar Analytics on request

REVENUE RECOVERY
Dynamic Retargeting Ads: Recover the Revenue Most Stores Leave Behind
The average ecommerce store loses over 70% of visitors who viewed a product or added it to their cart without purchasing. Dynamic retargeting ads serve those shoppers personalised ads showing the exact products they interacted with — across Google Display, Meta, and TikTok — until they return and buy.
We set up dynamic retargeting as a structured programme — not a single campaign — with distinct creative and bid strategies for cart abandoners, product-page visitors, and past purchasers.
Abandoned Cart Recovery Ads
Serve product-specific ads to shoppers who reached the cart or checkout but did not complete purchase. We test urgency-based creative, discount offers, and social proof variants to find what converts for your audience.
Product-Page Viewer Retargeting
Reach visitors who viewed specific product pages but did not add to cart. Segmented by product category, time since visit, and number of pages viewed — so budget goes to the warmest segments first.
Past-Purchaser Upsell Campaigns
Serve dynamic ads to existing customers featuring complementary products based on their purchase history. Post-purchase campaigns consistently deliver the highest ROAS of any campaign type in an ecommerce account.
Cross-Channel Dynamic Creative
We produce and test dynamic ad creative in the correct formats for each platform — responsive display ads for Google, catalogue ads for Meta, and product-linked video for TikTok — so you do not serve the wrong format on the wrong channel.
RESULTS
ROAS Numbers, Not Promises
These figures represent outcomes achieved across managed client accounts. Specific case study names and revenue numbers require written client authorisation before being named publicly on this page.
Fashion & Apparel — DTC Shopify Brand
Inherited an account with 14 overlapping Shopping campaigns and no product feed custom labels. Consolidated to 4 margin-segmented campaigns, rebuilt PMax asset groups by category, and added dynamic retargeting for cart abandoners. Revenue grew while total spend dropped by 22%.
Home & Garden — WooCommerce Store
Identified 340 disapproved products in Merchant Centre blocking 28% of inventory from Shopping. Fixed feed data, added missing GTINs, and restructured campaigns around high-margin product categories. Launched cross-channel dynamic retargeting that now accounts for 31% of total ad-attributed revenue.
Health & Wellness — Shopify Plus
Built a prospecting-to-purchase programme combining Meta Advantage+ Shopping for new customer acquisition with Google Shopping for intent capture and a three-stage dynamic retargeting sequence. Integrated with Triple Whale for cross-channel attribution so the client could see blended ROAS across all platforms in one view.
SPECIALISATION RATINGS
GrowthCatalyx vs General PPC Agencies: Why Ecommerce Needs a Specialist
General PPC agencies apply the same frameworks to SaaS, local services, and ecommerce. The result for online stores is usually inflated click volume and ROAS numbers that do not connect to actual revenue.
| Capability | GrowthCatalyx | Typical General PPC Agency |
|---|---|---|
| Product feed optimisation (titles, GTINs, custom labels) | ✓ Included in every engagement | ✗ Rarely offered or understood |
| Shopify pixel and Conversions API setup | ✓ Verified before spend begins | ✗ Often assumed to be working |
| Margin-based campaign segmentation | ✓ Standard practice | ✗ Not typically available |
| Dynamic retargeting ad setup (product-level) | ✓ Cross-platform, product-level | ✗ Generic display retargeting only |
| Revenue reporting (not just conversion count) | ✓ Weekly, by product category | ✗ Conversion volume reporting |
| PMax asset group strategy and audience signals | ✓ Full optimisation included | ✗ Often unmanaged after launch |
QUALITY FRAMEWORK
How We Apply E-E-A-T to Ecommerce PPC
Google's E-E-A-T quality standards affect not only organic search rankings but also the effectiveness of landing pages and content you amplify through paid media. We build campaigns with this in mind.
Experience
We have managed over $85M in ecommerce ad spend across fashion, home, health, electronics, and food categories. Our frameworks are built on patterns from real accounts — not theoretical best practice.
Expertise
Our team holds current Google Shopping, Performance Max, Meta Blueprint, and TikTok for Business certifications. We are also trained in AI Search Optimisation for ecommerce product landing pages and feed-driven ad formats.
Authoritativeness
We publish original ecommerce PPC research and contribute to industry publications on topics including Shopping feed strategy, dynamic creative testing, and first-party data approaches post-cookie deprecation.
Trustworthiness
Clients retain full ownership of all ad accounts, product feeds, pixel data, and audience lists. Our contracts include revenue benchmark clauses so both parties are accountable to agreed performance targets from day one.
TRANSPARENCY & DATA OWNERSHIP
Your Data. Your Accounts. Your Results.
Ecommerce brands often discover after leaving an agency that they do not own the product feeds, pixel audiences, or account history built during the engagement. GrowthCatalyx is structured to prevent this from happening.
Every asset we build — from feed configurations to remarketing audiences — sits inside accounts owned by you from the first day of the engagement.
You own every ad account
We manage inside your Business Manager and Google Ads accounts. You are the account owner — we are a managed user. All data, audiences, and history remain yours if you ever decide to change agencies.
No markup on media spend
Our fee is a flat retainer or agreed percentage of spend — stated clearly in the contract. We do not add undisclosed margin to your media budget or accept platform rebates that are not passed back to you.
Raw data access, always
You receive live access to every report, dashboard, and raw export. We do not use proprietary platforms that lock your performance data behind a login that disappears when you stop paying.
ROAS benchmarks in your contract
We agree target ROAS and cost-per-purchase benchmarks at the start of the engagement. If we miss them without a documented reason and recovery plan, our contract terms address this directly — you are not left guessing.
