Web3 ad networks using on-chain activity-based billing challenge Google Ads by offering precise targeting of active crypto users, leveraging blockchain transparency. Platforms like Blockchain-Ads reach 11M+ wallet holders across 10,000+ sites, delivering 1B+ daily impressions with performance-based pricing (CPM/CPA). This contrasts with Google’s broader, less crypto-specific approach, which faces restrictions on blockchain ads. Web3’s focus on wallet behavior and privacy via zero-knowledge proofs could erode Google’s dominance in niche crypto markets, though broad reach keeps Google competitive.[](https://www.blockchain-ads.com/post/blockchain-ads-web3-marketing-campaigns)[](https://payouts.com/10-best-web3-ad-networks-to-scale-in-2025/)[](https://www.blockchain-ads.com/post/best-crypto-ad-networks)
