You’ve got a project coming up. Maybe you need customer feedback, employee opinions, or market research for a new product. The big question hits you: should you send out an online survey or go with good old face-to-face interviews? Both works, but they feel worlds apart in cost, speed, and the kind of answers you actually get.
I’ve run both types hundreds of times for small startups, big corporations, and even non-profits on a shoestring budget. Here’s the straight talk you need to pick the right one without wasting time or money.

The Speed and Cost Battle (Where Online Usually Wins Big)
Let’s start with the part everyone cares about first—how fast and how cheap.
Online surveys are ridiculous when it comes to speed. You build the questions in the morning, send the link at lunch, and by dinner you already have 300 responses. I once needed feedback on a new app feature on a Friday afternoon. Sent a Google Form link to our user Slack channel and had 180 replies before the weekend. Try doing that knocking on doors.
Money? Even more lopsided. A decent online tool (Typeform, SurveyMonkey, Google Forms free!) plus a small incentive can cost you under $500 for a thousand responses. Face-to-face? You’re paying interviewers by the hour, travel, printing, maybe venue rental. A moderate in-person study of 200 people in one city easily runs $15,000–$30,000. If your budget is tight, online is usually the obvious answer.
But cheap and fast isn’t always better. Keep reading.
Data Quality: Where Face-to-Face Still Has the Edge
Here’s the dirty secret most “online-is-always-better” articles won’t tell you: people lie more, skim more, and drop out more when no human is looking at them.
Online, you get straight-lining (picking the same answer for every grid question), speeders (finishing a 15-minute survey in 3 minutes), and bots if you’re not careful. I’ve seen response quality crash the moment you go fully remote without strict controls.
Face-to-face is different. When someone is sitting across from you, they think twice before rushing or making stuff up. You can probe: “You said the price is too high—can you tell me what number would actually feel fair?” That follow-up is gold. You also read body language. A hesitation, a frown, a laugh—those little cues tell you more than any rating scale.
Real example: A coffee shop chain I worked with ran an online survey about store atmosphere. Most people said “it’s fine.” Then we did 40 in-person interviews. Turns out customers hated the bright LED lights that made everyone look sick. That never showed up online because nobody thinks “lighting” when they’re clicking boxes on their phone.
Reach and Who You Actually Talk To
Online wins on sheer numbers and geography. Want answers from dbb4 people in ten different countries tomorrow? No problem. Want mothers with toddlers in rural Nebraska? You can target them with Facebook ads for pennies per click.
Face-to-face limits you to wherever your interviewers can physically go. That’s a problem if your audience is spread out or hard to reach (doctors, CEOs, night-shift workers).
But sometimes the “hard to reach” group is exactly why in-person works better. Older adults, low-income households, and people with low digital literacy often skip online surveys completely. If your product serves seniors or offline communities, showing up in person is frequently the only way to get their real voice.
When Honesty Really Matters
Some topics are just awkward on a screen.
Try asking about income, illegal behavior, health issues, or anything embarrassing through a laptop. People freeze up or give the “socially acceptable” answer. Put a trained interviewer in the room who builds rapport for five minutes first, and suddenly people open up.
Same with complex topics. If you’re testing reactions to a new medical device or financial product, a 10-minute conversation beats a 40-question online form every time.
The Dropout Nightmare
Online surveys suffer from high abandonment. The average completion rate hovers around 60-70% if you’re lucky, and drops hard once you go past 10-12 minutes. Every extra question costs you respondents.
In-person interviews? Almost nobody walks out halfway once they’ve agreed and you’re sitting together. You get the full story.
Practical Decision Checklist (Copy-Paste This)
Still not sure? Run your project through these questions:
1. Budget under $5,000? → Go online.
2. Need answers in under a week? → Online.
3. Talking to people spread across multiple cities/countries? → Online.
4. Is the topic sensitive, complex, or emotional? → Lean in-person.
5. Your audience is over 65 or has limited internet? → In-person.
6. Do you need video/audio recordings and facial reactions? → In-person (or video calls as middle ground).
7. Sample size over 400? → Online is usually the only realistic option.
8. Do you sell high-ticket or life-changing products (cars, insurance, healthcare)? → Invest face-to-face.
If most answers point one way, you’ve got your winner.
The Smart Middle Path Almost Nobody Talks About
You don’t always have to pick one or the other.
I use hybrid approaches all the time:
- Start with a broad online survey to spot trends and segment the audience.
- Then invite the most interesting respondents (extreme lovers/haters, specific demographics) for in-person or Zoom interviews.
You get scale + depth without breaking the bank.
Incentives: What Actually Works?
Online respondents are cheap. A $5 gift card or entry into a $100 draw usually does the trick.
In-person needs more respect for people’s time. $30–$75 cash (or equivalent gift) is standard, especially for longer sessions. Skimp here and you’ll either get no-shows or low-effort participants.
My Personal Rule of Thumb After 15+ Years
- Quick pulse checks, pricing tests, concept screening, big sample sizes → online, always.
- Anything that can make or lose you serious money, anything emotionally charged, anything where misunderstanding the “why” is dangerous → at least some face-to-face.

Final Thought
There’s no universal “best” method. There’s only the best method for your specific goal, budget, timeline, and audience right now.
Pick wrong and you either blow your budget on fancy interviews nobody needed, or you launch a product based on garbage data from lazy online clickers.
Pick right and you get answers you can actually trust—and act on.
