Why intent clustering beats product-based campaign structure
The old playbook — one campaign per product or service category — made sense when keyword match types were strict and bids were manual. In 2026, with Smart Bidding reading signals from the entire session, campaign structure should match how buyers actually think: by intent. A researcher typing "best HVAC brands 2026" and a buyer typing "HVAC installation cost near me" are not in the same ad group even if they are both interested in the same product. Intent-clustered campaigns give Smart Bidding cleaner training data, let you write ad copy that matches buyer stage, and make budget allocation decisions obvious — you put more money on the clusters that convert fastest.
