Google Shopping vs Performance Max for Ecommerce UK: Which Should You Choose?

Google Shopping vs Performance Max: The UK Ecommerce Showdown

If you're running an ecommerce store in the UK, you've probably asked yourself: should I run Google Shopping campaigns, Performance Max campaigns, or both?

It's a question I get asked constantly by ecommerce brands looking to scale their Google Ads. And honestly? The answer isn't as straightforward as Google would have you believe.

What's the Difference?

Google Shopping campaigns give you granular control. You choose which products to advertise, set bids at the product level, and see exactly which search terms trigger your ads. It's the transparent option.

Performance Max campaigns use Google's AI to serve ads across all Google properties — Search, Shopping, Display, YouTube, Gmail, and Discover. Less control, but potentially broader reach.

When Shopping Campaigns Win

Shopping campaigns are ideal when:

• You need tight control over bids and budgets
• You want to see exactly which search terms convert
• You're running brand vs non-brand split strategies
• You have a smaller catalogue and want maximum visibility

For many UK ecommerce brands, especially those with 50-500 SKUs, Shopping campaigns remain the backbone of profitable Google Ads.

When Performance Max Makes Sense

PMax shines when:

• You have strong creative assets (images, videos)
• Your product feed is well-optimised
• You're comfortable with less visibility into search terms
• You want to test YouTube and Display alongside Shopping

The Hybrid Approach

Most successful ecommerce Google Ads strategies use both. Run Shopping for your core products where you need control, and use PMax to capture incremental demand across Google's network.
