Short answer
Signage ROI publishes practical guides on digital signage and narrowcasting: what it is, how it works, what it costs and how to set it up for a restaurant, gym, church, school, waiting room or shop. Every page shows when it was last verified. The site launched in October 2026.
What you will find here
- Learn: plain-language explanations, checklists and a glossary.
- Use cases: how to set up screens for a specific kind of place.
- Best of lists with the criteria stated first, and migration guides for platforms that are being retired.
- Calculators for the return on investment of screens.
Pages are written to be read by people and quoted by software: a short answer at the top, tables for comparisons, a verification date, and a Markdown version at the same address with .md appended.
