Positioning lives in the buyer's head
On Beyond Referrals, positioning is how the market hears what you say, not what you say about yourself. Tim Kilroy's positioning playbook argues that buyers categorize an agency in the first eight seconds, using options they already understand. If you do not fit a construct they recognize, they forget you.
That is why your work has to back the words. If your case studies say everyone, your tagline cannot say specialist; the market reads the case studies.
