Your buyers are asking AI before they ask you. According to Forrester research cited by Ahrefs, 94% of business buyers now use AI search when making purchase decisions, and they rate it above vendor websites, product experts and sales reps. Consumers are not far behind: NielsenIQ puts it at 42% of shoppers researching products with AI. So budgets are moving toward AI search.

The good news is that leadership does not need a perfect number. They need a reasonable estimate they can trust and compare over time. Between what you can track and what your customers tell you, you have enough data to build one.

Value includes sales, traffic, awareness among people who never click, conversions and better-informed buyers. Cost includes content, technical work, tools and team time. Revenue is the number leadership…
