Most Google Ads problems in large eCommerce stores aren’t bidding or creatives — they’re catalog and Merchant Center problems. I help large-catalog eCommerce brands fix feed architecture, SKU visibility, and Performance Max structure so Google Shopping can scale without margin loss, disapprovals, or black-box behaviour. About me I specialise in Google Ads and Google Merchant Center optimisation for large-catalog eCommerce stores — typically brands managing hundreds to tens of thousands of SKUs and spending $5k–$100k+/month on Google Ads. This is not generic campaign management. At scale, performance is dictated by: - Feed architecture and attribute quality - SKU-level eligibility and visibility - How Performance Max allocates spend across products - Silent disapprovals, policy risk, and data fragmentation - Shopping & Search cannibalisation That’s the layer I work at. What I actually do I work at the structural level, not surface-level optimisations: Google Merchant Center architecture - Feed diagnostics, disapprovals, and eligibility issues - Attribute quality and policy stability at scale - Supplemental feeds, rules, and automation Large-catalog Google Shopping & PMax structure - SKU-level and margin-aware segmentation - Product inclusion/exclusion logic - Preventing PMax over-aggregation and wasted spend Feed management & automation - Scalable feed setups that survive pricing, seasonality, and catalog growth - Attribute enrichment for better matching and coverage Visibility & control - Understanding which SKUs actually drive profit - Identifying where revenue quietly leaks despite “healthy” ROAS Results & experience ✔ 300+ eCommerce catalogs restructured for scale ✔ 500k+ SKUs managed across multiple verticals ✔ 4.8x average ROAS achieved after structural fixes ✔ 41% average CPA reduction once feed and Merchant Center issues were resolved In many cases, performance improvements came from feed and Merchant Center changes alone — not bid or creative tweaks. Who I’m a good fit for ✔ Large-catalog eCommerce stores (250+ SKUs, usually much more) ✔ Brands running or preparing to scale Google Shopping / Performance Max ✔ Teams experiencing disapprovals, unstable ROAS, or margin pressure ✔ Founders or Heads of eCommerce responsible for revenue, not just clicks Who I’m not a good fit for ✘ Small stores with simple catalogs ✘ Clients looking for generic PPC management or “daily optimisations” ✘ Businesses where Google Ads is a minor channel ✘ Projects focused purely on creatives or copy testing How we typically start - Most clients begin with a Merchant Center & Catalog Risk Audit, which includes: - Merchant Center health & disapproval analysis - Feed quality and attribute scoring - Shopping & Performance Max structure review - SKU-level prioritisation and leakage identification You’ll receive clear, written findings and priorities — not a slide deck, and not a sales pitch. If you’re managing a large catalog and Google Ads performance feels fragile or opaque, this is usually a structural issue — not a campaign one. Get in touch if that sounds familiar.
