Meta vs. Google in 2026: where should your next euro go?

Clients ask me this every quarter, usually hoping for a clean answer. There isn’t one — but there is a framework that makes the decision fast instead of political.

Google captures demand. Meta creates it. If someone is already searching for what you sell, Google Search is close to free money — you’re just paying to be found. If nobody’s searching yet, Meta (and TikTok) are where you convince them they have a problem worth solving.

Before shifting a single euro, I check three things:

• Search volume for your category. High, growing search volume usually means Google Search has room left. Flat or tiny volume means the ceiling is close, and new budget belongs on social.
• Funnel stage of existing campaigns. If Meta is mostly retargeting a small warm audience, more budget won’t scale — it’ll just get expensive. That’s a signal to widen the top of funnel, not to add spend to the same ad set.
• Creative fatigue. A Meta campaign losing efficiency for weeks isn’t a platform problem, it’s a creative problem. Don’t reallocate budget away from a channel that just needs new creative.

The honest answer is almost never “move it all to X.” It’s “Google for the demand that already exists, Meta for the demand you still have to build” — and the ratio between the two should shift every quarter as your category matures.
