# What is Product Feed?

What is Product Feed? A structured file (XML/CSV) with details for every product, sent to Google Shopping, Facebook Catalog, and Amazon.

## How it works in practice

A bad feed means bad campaigns. Inaccurate titles, small images, and outdated prices all directly hurt ROAS — no matter how much you spend.

## Related metrics

- Merchant Center — receives the feed
- Google Shopping — displays items from the feed
- PMAX — relies on feed quality
- Meta Catalog — Meta's equivalent

## Common misconception

'Exporting an XML feed and uploading it is enough.' An automated feed often lacks: keywords in the title, color/size/material, and images at 800x800+. Google rejects 20-40% of products in poorly built feeds.

## How to fix it

Feed approved but performance poor? (1) Titles: '[Brand] + [Product] + [Attribute] + [Size/Color]', (2) accurate Google Product Category, (3) Merchant Center → Diagnostics, (4) update prices and availability daily.

## Real-world example

A clothing store: PMAX ROAS was 1.8. The feed had titles like 'Blue Shirt' and 400x400 images. Improving the feed and using 1000x1000 images brought ROAS to 3.4 within 4 weeks.

## Where to start

Invest a full day improving your feed before scaling Shopping budget. Tools: DataFeedWatch, Simprosys (Shopify).
