What are survey methodologies?
A survey methodology is a tested, standardised way of asking a question so you get a reliable answer. Instead of asking “however it comes out”, you use a structure that has already proven itself — such as NPS, CSAT or the employee climate survey — to measure exactly what matters.
They matter because they turn loose opinion into comparable data. With the right methodology you track change over time, compare periods and departments, and decide based on the voice of the customer and the employee experience — not on hunches.
In practice each methodology answers a different business question: loyalty, satisfaction, effort, engagement, market perception. Knowing when to use each one is what separates an online survey that drives action from a form nobody reads. That is what this page helps you decide.

Frequently asked questions about methodologies
What is NPS?
NPS (Net Promoter Score) is a methodology that measures customer loyalty with a single question: "on a scale of 0 to 10, how likely are you to recommend our company to a friend or colleague?". The answers sort customers into promoters (9–10), passives (7–8) and detractors (0–6).
How do you calculate NPS?
NPS is the percentage of promoters minus the percentage of detractors. The result runs from -100 to +100. On Loyvox that calculation is automatic: you follow the score in real time, with no spreadsheet formula.
What is the difference between NPS and CSAT?
NPS measures loyalty and the long-term relationship with the brand; CSAT measures satisfaction with one specific interaction (a purchase, a support call). Use NPS to track loyalty over time and CSAT right after a one-off contact.
When should you use CES?
Use CES (Customer Effort Score) when you want to measure how much effort a customer spent to get something resolved — opening a ticket, exchanging a product, cancelling. The lower the effort, the higher the chance of repurchase. It fits best after support and self-service interactions.
When should you use eNPS?
eNPS (Employee NPS) measures team engagement by asking how far an employee would recommend the company as a place to work. Run it quarterly as a fast, anonymous read on the employee experience.
How do you measure customer satisfaction?
Combine methodologies: CSAT right after each interaction, NPS for the relationship as a whole, and CES for friction points. On Loyvox you build these surveys with AI, share them by link, QR code or WhatsApp, and see results in real time.
How do you measure employee satisfaction?
Use eNPS for a quick read and a climate survey for a deep diagnosis across dimensions (leadership, recognition, communication). Both can be fully anonymous, which raises how honest the answers are.
Which methodology should I choose?
It depends on what you want to measure: loyalty → NPS; post-service satisfaction → CSAT; effort → CES; internal climate → climate survey; team engagement → eNPS; consumers → market research. Use the "how to choose" guide above or start from a ready-made template.
Is the climate survey anonymous?
Yes. On Loyvox both the climate survey and eNPS can run anonymously — collecting no IP and no identification — which is essential for honest answers and for LGPD compliance.
How do I create a satisfaction survey?
Describe what you want to find out and Loyvox AI builds the survey in seconds, or pick a ready-made NPS, CSAT or satisfaction template. Then share it by link, QR code or WhatsApp and follow the answers in real time. Start free, no card.
