Selling on Google and Social Platforms: FAQs
Short answers to the questions UK sellers ask most about product data, Google Merchant Center and selling on Instagram, Facebook, WhatsApp and TikTok Shop. Each answer links to a full guide. In short: fix your product data first, keep price and stock in sync, add one channel at a time, and check each platform’s current rules before you rely on them.
Contents
Product data
What is a product database?
The master record of what you sell, from which each channel’s feed is made. See selling online from one product database.
Why do I need one master?
Separate uploads drift out of sync and cause mismatches and disapprovals. See selling online from one product database.
Google Merchant Center
How do I set up Google Merchant Center?
Create an account, claim your website, add shipping and returns, and supply a feed. See Google Merchant Center setup for UK sellers.
Why were my products disapproved?

What is a GTIN and why is it missing?
The barcode number that identifies a product. See how to fix a missing GTIN.
What is a price mismatch?
The feed price differs from the product page price. See how to fix a price mismatch.
What if my whole account is suspended?

Can someone check my feed?
