Here's a mistake that kills survey accounts quietly: buying the right type of proxy (residential — good) with the wrong session behavior (rotating every request — fatal). The account looks perfect on paper and gets disqualified mid-survey, every survey, and nobody can figure out why.

The reason is simple once you see it: a survey is one continuous session. Change your IP in the middle of it and the panel sees a different person finishing someone else's survey. That's an instant disqualification — sometimes an instant ban.

What rotating actually does

A rotating proxy gives you a new IP on every request (or every few minutes). For web scraping, that's ideal — each request looks like a different visitor, and no single IP gets rate-limited. Scrapers love rotation.

For surveys, it's poison. You start a 20-minute survey on one IP, and by question 12 you're on a different IP in a different city. The panel's fraud system sees a session hijack in progress. Best case: disqualified. Worst case: the account gets flagged for the trust score hit that throttles your future invites.

What sticky does

A sticky session holds the same IP for a set duration — 10 minutes, 30 minutes, an hour, sometimes days. You start the survey on an IP in Austin, you finish the survey on that same IP in Austin. The panel sees one consistent respondent, which is exactly what you are.

The mechanics: most providers implement stickiness through your proxy credentials. You append a session parameter (often something like session-abc123) to the username, and every request with that session string exits through the same IP until the TTL expires. Different session string per profile = different IP per profile.

How long should sticky last?

Long enough to cover your longest survey plus buffer. Most surveys run 5–25 minutes, so a 30-minute sticky session is the practical standard — it comfortably covers any single survey. Some providers (IPRoyal, for example) let you set TTLs up to days, which is useful if you want the same IP every time a profile logs in, not just within one survey.

There's a subtle second benefit to long stickiness: IP consistency across sessions. Panels notice when an account's IP changes every login versus staying stable. An account that always arrives from the same residential IP looks like a real person on home Wi-Fi. An account on a different IP every day looks transient. For your main accounts, longer sticky durations (or static residential IPs) are worth it.

The correct setup, step by step

  • Step 1 — One session ID per profile. Generate a unique session string for each browser profile: survey-emma-01, survey-raj-01. Never reuse a session string across profiles.
  • Step 2 — Set TTL to 30+ minutes. In your provider's dashboard or via the session parameter, set the sticky duration to cover your longest surveys.
  • Step 3 — Match the geo. The sticky IP's city must agree with the profile's timezone and the account's stated location (the mismatch problem).
  • Step 4 — Verify before surveying. Open an IP checker in the profile, note the IP, wait 10 minutes, check again. Same IP = sticky working.

Virtually every major provider supports this the same way — Evomi, Floppydata, Decodo, IPRoyal, Bright Data, Oxylabs, SOAX all offer sticky sessions; only the parameter format and max TTL differ. Check your provider's docs for the exact string format. Provider-specific walkthroughs: Evomi setup, Floppydata setup.

When rotating is actually fine

Rotation isn't evil — it's just the wrong tool for surveys. Use rotating where it belongs: scraping public data, checking SERPs, ad verification, price monitoring — anything where each request is independent. The rule of thumb: if the task has a login session, go sticky; if it's stateless requests, rotate.

The mistake that burns everyone

Leaving the provider's default (rotate every request) on and assuming "residential = safe." The IP type was right; the behavior was wrong. If your surveys keep dying halfway through and your setup looks correct, check the session behavior first — it's the most common invisible killer I see.

Quick check: do you know whether your current proxy is sticky or rotating right now? If you're not sure, that's worth 30 seconds in your provider's dashboard.
