| Red line | Reason | Correct practice |
|---|---|---|
| ❌ Looking only at price and not at value | A price war eats into profit | Focus on the competitor's differentiated selling points |
| ❌ Irregular data collection | Incomplete data cannot be analyzed | Run the collection at a fixed time |
| ❌ Collecting without analyzing | The data is meaningless | Every collection must produce insights |
| ❌ Analyzing without acting | Monitoring loses its meaning | Every analysis must produce action items |
💡 Usage advice: start with "weekly monitoring" and expand to monthly deep analysis once it is stable. Start with the free tools (CamelCamelCamel + Google Alerts) and only start paying after the value has been validated.
