Strategy starts with business outcomes, not topics
Before keyword research, decide what business outcome the content program serves. Demo bookings? Product trials? Local lead forms? Press mentions? Each outcome implies different topics, formats, and distribution channels. A SaaS strategy aimed at trial signups looks nothing like a local services strategy aimed at form fills.
Document the outcome, the leading indicators (rankings, traffic), and the lagging indicators (pipeline, revenue) up front. Without this, you can't tell whether the content program is working.
