2. Focus on Questionnaire Design, Not Just Length
Self-Serve:
It’s easy to add too many questions. Keep it short (under 10 minutes) and ensure every question has a purpose.
➡️ Tip: Test your survey internally first, people often forget how much jargon sneaks in. Avoid double-barrelled questions (“Was the product affordable and easy to use?”).
Full-Service:
The best customer satisfaction survey companies bring rigour to question wording and scale design, ensuring results are valid and comparable over time and can identify the questions that really matter.
➡️ Ask: “Can you explain why you’re using this scale?” If an agency can’t justify it, that’s a red flag.
3. Get Sampling Right from the Start
Self-Serve:
One of the biggest mistakes is only surveying your easiest-to-reach customers.
➡️ Tip: Segment your audience before launching. Include both satisfied and dissatisfied customers for balance, and avoid over-sampling one group (like recent buyers).
Full-Service:
Agencies ensure representative sampling and manage quotas for different segments. Many agencies have access to trusted audiences so they can target high-quality answers.
➡️ Ask: “How do you make sure our sample represents all customer types?” A good agency will discuss weighting, non-response, and bias openly.
4. Monitor Fieldwork: Don’t “Set and Forget”
Self-Serve:
DIY users often launch surveys and wait for responses without checking progress.
➡️ Tip: Monitor completion rates and dropout points daily. If people are abandoning halfway through, your questions might be confusing or too long.
Full-Service:
Agencies manage reminders, quotas, and quality control during fieldwork, but you should still stay involved.
➡️ Ask: “Can we receive interim updates?” Transparency during data collection prevents surprises later.
5. Protect Data Quality
Self-Serve:
Data quality is where many self-run projects fail.
➡️ Tip: Add logic checks (e.g., trap questions or attention filters) and review open-ends for gibberish. Poor data is worse than no data, it can send you in the wrong direction.
Full-Service:
Professional researchers automatically filter “speeders,” duplicates, and bots which will ruin any survey without due care and attention
➡️ Ask: “What quality controls are in place?” Reputable agencies will explain their process clearly and show audit examples.
6. Make Sure Reporting Answers ‘So What?’
Self-Serve:
Most platforms show bar charts, fine for feedback, but limited for decision-making. This can be helpful for content or used as visuals. This needs to be considered right from the start within your objectives.
➡️ Tip: Before launching, decide how you’ll report results. Plan to compare groups, track trends, and interpret open comments, not just export a spreadsheet.
Full-Service:
Agencies deliver structured reporting with context, commentary, and recommendations.
➡️ Ask: “Can you show me an example report?” You’ll quickly see whether they provide insight or just data.
7. Understand Cost vs. Effort
Self-Serve:
DIY looks cheap, but remember to factor in staff time for design, cleaning, and analysis. This is best for when surveys are simple and low maintenance.
➡️ Tip: Estimate your total hours, if it exceeds 15–20, a managed option might actually be better value.
Full-Service:
Agencies charge more upfront, but save time and provide expert analysis. In the long-term, and often the short-term, it will be far more value for money. One poorly designed survey can make the whole exercise a waste of time and money. Using experts offsets this risk.
➡️ Ask: “What’s included in the fee?” Check whether revisions, debriefs, or extra segmentation cost more. Transparency matters.
8. Think About Scale and Future Use
Self-Serve:
Self-run surveys are great for one-offs, but scaling can get messy, especially across multiple regions or languages. Consistent surveys are the only way to retain up to date customer satisfaction data and to monitor the progress of initiatives.
➡️ Tip: Plan your survey structure so future comparisons are possible (e.g., identical wording, consistent scales).
Full-Service:
Agencies manage complex, multi-market projects and ensure continuity year-on-year. The best research companies will build these so that progress can be tracked, even if this isn’t requested from the start.
➡️ Ask: “How will this data be structured for future tracking?” Smart setup now avoids major headaches later.
9. Check Credibility and Independence
Self-Serve:
Internal surveys are fine for operational feedback, but external audiences (boards, investors, regulators) may question impartiality.
➡️ Tip: If credibility matters, consider independent verification or peer review of your results.
Full-Service:
Accredited agencies (like Vision One) follow industry standards such as ISO 20252, given to only 100 companies globally, and MRS guidelines, ensuring credibility and compliance.
➡️ Ask: “Are you accredited or independently audited?” It’s the simplest quality check there is.
10. Turn Results into Action
Self-Serve:
The biggest gap in DIY surveys is follow-through.
➡️ Tip: Before analysing, decide who will act on findings and how success will be tracked. Insights lose value if they don’t lead to change.
Full-Service:
Agencies often run debrief sessions and help turn results into strategies for improvement.
➡️ Ask: “How will you help us move from findings to action?” Look for partners who focus on outcomes, not just output.
Final Thoughts
Both self-serve and full-service approaches can deliver value, it’s about choosing what aligns with your resources and goals.
If your goal is quick, tactical feedback, self-serve can be the right tool.
