How to analyse product performance across sales channels
01
Why does it matter?
A full picture of marketing results is key to judging what works and finding areas to strengthen.
Without a single source of truth each platform reports its own result and real product performance stays hidden.
02
How to check if the problem exists?
If you look at product data from your feed, GA4, Google Ads, Meta Ads and your store separately, in different dashboards, the problem exists.
Also compare revenue and orders in GA4 with your store engine. A gap above 15% means segmentation should rely on store data.
03
How to use the feed in your ad account?
Data Octopus joins all sources on a common key — the product or variant ID. In the product performance view you analyse impressions, clicks, cost, revenue and ROAS from several channels at once, by product, brand or category.
Insights flow back into the feed as labels — e.g. products strong in one channel and weak in another — and steer campaigns right away.
04
How to measure results?
The result: visible gaps between ad-platform metrics and between GA4 and your store — and budget decisions based on one consistent data source.
