Visibility TAM / SAM / SOM

Framework · Market sizing · visibility-adapted

Market sizing adapted to DIGITAL visibility — question volume, not fabricated revenue.

What it is

Traditional TAM/SAM/SOM estimates Total, Serviceable, and Obtainable revenue. Those numbers are notoriously easy to hallucinate.

How Magrios runs it on evidence

Magrios sizes the VISIBILITY market instead, from evidence you can open: TAM = the total set of buyer questions researched in your category. SAM = the questions relevant to your positioning and audience. SOM = the questions you can realistically win next, ranked by evidence and current whitespace. Every layer is a count of real questions with sources — never a revenue guess. If you want revenue-based sizing, the classic version ships as an editable template.

Adapted for the visibility market: this framework measures question volume, share of voice, and citation coverage — real, sourced counts — rather than fabricated revenue.

How to build it

1. TAM: total buyer questions researched in the category.
2. SAM: the subset matching your ICP and positioning.
3. SOM: the winnable subset, ranked by whitespace and evidence confidence.
4. Track SOM capture scan over scan as your obtainable share.
