There is no universal winner between Google Ads and Meta Ads. The stronger starting point depends on how customers discover the product and how much intent already exists.
Google captures existing intent
Search and Shopping campaigns are powerful when people already look for the product category and the store has competitive pricing, clear feeds and conversion-ready product pages.
Meta creates and shapes demand
Meta is often stronger when the product benefits from demonstration, visual storytelling or creative angles that help customers understand why it matters.
The store experience decides what scales
Whichever channel starts first, product content, site speed, trust and measurement will determine how efficiently the budget can grow.
