Google Ads for crypto: what works, and what to run instead

Short answer: Google Ads can work for exchanges, wallets, and fiat-onramp products in permitted countries, with certification. For most DeFi protocols and web3-native products it is somewhere between restricted and pointless, and the reasons are only half about policy.

The policy half

Google’s crypto advertising rules have loosened and tightened repeatedly over the years, and they differ by country and product category. The broad shape as it stands: centralized exchanges and wallet providers can get certified to advertise in a list of countries; a long tail of crypto products either does not fit an allowed category or is explicitly disallowed, with DeFi trading protocols named in the prohibition and DEXs, yield products, and NFT projects faring little better. Teams that push through anyway tend to collect account suspensions, and appeals go through the same opaque machinery as everyone else’s. If you are in the allowed categories, do the certification properly and read the current policy for every market you target, because the details move faster than any blog post can track them.

The half nobody talks about

Suppose policy were no obstacle at all. Google’s superpower is intent: someone typed a thing, and you can pay to be the answer. That is genuinely valuable for “buy bitcoin with card” or “best crypto wallet”, which is why onramps and exchanges make it work. But for a protocol, the queries with real intent are thin, expensive, and full of competitors’ brand names you cannot use. And Google’s targeting knows searches and demographics, not wallets. It cannot tell a liquidity provider from a teenager researching a school essay, and its conversion tracking stops at your landing page, blind to the deposit that happens in a wallet three clicks later. You end up paying search-engine prices for audience-network certainty.

Where Google Ads earns its keep

• Fiat onramps, exchanges, consumer wallets. Real search volume, permitted categories, conversions that happen on your own site where you can measure them.
• Branded defense. If competitors bid on your name, owning your own branded queries is cheap insurance.
• Genuinely mainstream plays. If your product is aimed at people who do not yet have wallets, meeting them on Google is coherent. Just measure it as a funnel that starts from zero crypto context.

What to run for the web3-native audience

If your market is people who already use web3 products, the efficient move is to advertise where wallets are connected and behavior is visible: inside wallets, explorers, and dapps, targeted by what users do onchain rather than what they search. That is the category Specify operates in, so weigh our view accordingly, but the structural argument stands on its own: intent data finds people who want to start, behavioral data finds people who already do the thing you monetize. Most protocols need the second group. Our guide to advertising a crypto project covers how the channels fit together, and the network comparison covers who does what.

A sane split

Teams with both audiences usually land on a split: Google for branded queries and any permitted mainstream funnel, behavioral networks for the crypto-native core, and an incrementality test on each so the budget follows proof rather than dashboards. If the first dollar has to go somewhere, put it where you can verify what it bought.
