Ad ROI Optimisation for E‑Commerce

Trusted by leading brands & retailers

Why Ad ROI Is Hard to Scale

Even with the right budget and strategy, poor feed quality or static rules can erode ROI. Common issues include:

Wasted spend on low-stock or low-margin SKUs
Poor visibility due to unoptimised product titles
Disconnected product logic across platforms
Static campaigns running across dynamic markets

NetAmplify closes the loop between product data and advertising performance.

How does NetAmplify improve my ad ROI and ROAS?

NetAmplify boosts ad ROI by ensuring only high‑performing products are advertised and by enriching product data for better relevance. Performance‑based feed filtering excludes low‑margin or low‑stock SKUs, while contextual rules adapt content to promotions, seasonality, or buyer intent.
Brands like Eden Park increased ROI by automating feed optimisation across their campaigns, cutting wasted spend and focusing on products that convert.

Can NetAmplify help reduce wasted ad spend on low‑performing products?

Yes. By combining dynamic product labelling with performance‑based exclusions, NetAmplify prevents budget from being spent on SKUs that don’t convert.
For example, Wethenew improved Google Ads ROAS by 30% after excluding underperforming products and focusing on in‑stock, high‑demand items.

How does NetAmplify support A/B testing and ROI optimisation?

NetAmplify allows you to A/B test feed variants – such as titles, images, or custom labels – to identify which product attributes drive the best click‑through and conversion rates.
By linking performance back to feed quality, teams can make data‑driven optimisations that consistently lift ROAS. Kiehl’s, for instance, boosted online sales in the Nordics by improving feed content and testing performance‑oriented product attributes.
