Web3 advertising is a new form of digital marketing built on blockchain and decentralized technologies. Unlike traditional advertising, which relies on centralized platforms (like Google or Facebook), Web3 advertising gives users more control over their data and privacy. It allows advertisers to engage directly with users through transparent, trustless systems—often using smart contracts and crypto rewards.

Why does it matter?
Because it shifts power from centralized corporations to individuals. It promotes transparency, reduces ad fraud, respects user privacy, and creates fairer value exchange between advertisers and audiences—especially important in crypto, NFT, and blockchain ecosystems.
