How bots distort experiment results
Bots, crawlers, headless browsers, repeated requests and event spam can make variant performance look different from reality. Testvoy's bot-aware reporting approach focuses on making these signals visible and separable before they influence decisions.
Bot signature library
Signed ingest context
Rate-limit and abuse guard
SRM traffic quality check
Bot review workflow
Privacy-first data quality
Bot protection works for experiment accuracy and data security; it does not move unnecessary personal data, raw card data or sensitive customer data into the public marketing surface. The goal is to reduce polluted traffic deciding the winner and warn users before decision time.
- Is suspicious traffic visible separately?
- Is the dropped event reason understandable?
- Was the SRM warning taken seriously?
- Does event context match the right project/experiment?
- Was data quality read before the decision?
Example data-quality check
Example: a report shows unexpectedly high conversion. Before deciding, review bot signals, signed event context, dropped event reasons, rate-limit signals and SRM checks in order.
- 01
Open Report > Data quality
- 02
Check suspicious traffic count
- 03
Look for signature/context errors in dropped events
- 04
Inspect rate-limit or abuse guard signals
- 05
If SRM warning exists, hold decision or re-QA
- 06
Share the clean report with a shareable link
Traffic quality: healthy
SRM: no mismatch
Dropped events: 0.8% invalid context
Suspicious traffic: reviewed separately
Decision status: safe to reviewPractical scenario
A growth team changes CTA copy on the pricing page, connects signup_started and signup_completed goals, then reads Google Ads and returning visitor segments separately. If the result is promising, they share a report link with the client or leadership.
Common mistakes
Most mistakes come from wrong project keys, overly broad selectors, missing goals, staging/prod mixups, early decisions on small samples or skipping mobile QA.
Naming an experiment 'test'
Launching without a goal
Deciding on total CVR only
Sending screenshots instead of shareable reports
