Selling Online From One Product Database: Google, Social and More
A clean product database is the single source of truth for everything you sell: names, descriptions, prices, stock, images, barcodes, shipping and tax. Build it once, then publish it as feeds and catalogues to Google, Instagram, Facebook, WhatsApp and TikTok. Most selling problems start in this data, so fix it first and keep it accurate from one place.

What a product database is
A product database is the master record of what you sell. Each channel needs the same facts in its own format, so keeping one master and publishing from it prevents the mismatches that get products disapproved.
| Field | Why it matters |
|---|---|
| Title and description | What customers and search engines read |
| Price and sale price | Must match your product page exactly, including VAT where required |
| Stock and availability | Must match what you can ship |
| Images | Clear, unobstructed product photos with no promotional text |
| Barcode (GTIN) and brand | Identifiers that Google and other channels use to recognise products |
| Shipping and returns | Required by most channels, with accurate costs |
| Category | Helps channels place the product correctly |
How each channel uses it
- Google: a product feed goes to Merchant Center, and products appear in free listings and, if you pay, Shopping ads. See Google Merchant Center setup for UK sellers.
- Instagram and Facebook: a catalogue is set up through Meta’s business tools and approved before products appear.
- WhatsApp: a business catalogue can show products in conversations; check Meta’s current UK documentation.
- TikTok Shop: products are listed in the Seller Centre. See how to sell on TikTok Shop in the UK.
For how the channels fit together, see selling on Google, Instagram, Facebook and WhatsApp from one catalogue.

How to build it
- Audit what you have: export your products from your shop platform and look for gaps and mistakes.
- Define your fields: decide what each product must have.
- Clean the data: fix titles, prices, stock, categories and duplicates.
- Add identifiers: the correct GTIN and brand for each product. See how to fix a missing GTIN.
- Fix the images: clear, unobstructed photos with no sale text.
- Sync price and stock automatically from your shop to your feeds.
- Publish and monitor: check each channel’s diagnostics regularly.
The problems it prevents
Google disapproves products when the feed does not match your website, when barcodes are missing or wrong and when images break its rules. Our guide to why products are disapproved in Google Merchant Center lists the common causes, and our product feed health check reviews yours.
What we do
We clean and structure your product data, build one master product database and publish feeds to Google Merchant Center, Instagram, Facebook, WhatsApp and TikTok Shop wherever each channel allows. We then monitor errors and fix them. We cannot promise approval, because each platform decides.
Our price: from £750 as a one-off set-up, then £149 a month for monitoring and fixes.
Before you start
Your website must be accurate and trustworthy too: clear prices, delivery and returns information, contact details and a secure checkout. See what a small business website costs in the UK.
Frequently asked questions
What is a product database?
The master record of everything you sell, including names, prices, stock, images, barcodes, shipping and tax, from which each channel’s feed is made.
Why not upload products separately to each channel?
Separate uploads drift out of sync, which causes price and stock mismatches and disapprovals. One master prevents that.
Which channels can use the same data?
Google, Instagram, Facebook, WhatsApp and TikTok can all use the same core product data, each in its own format and with its own rules.
How often should the data update?
Price and stock should update automatically and as often as they change. Review the whole database regularly.
Do I need barcodes?
Often, yes. Google disapproves products with missing or incorrect identifiers where they apply. See how to fix a missing GTIN.
Can you build it for me?
