VWO experiments,
powered by complete data.
VWO is the experimentation platform teams trust for A/B tests, multivariate experiments, and personalization. But experiments are only as reliable as the data behind them. When ad blockers strip the VWO tracking snippet or privacy browsers reset cookies mid-experiment, your conversion counts drop — and not evenly across variants.
Ingest Labs delivers conversion events to VWO server-side, ensuring every goal completion is recorded regardless of browser conditions. First-party identity keeps users bucketed consistently across sessions, so your experiments reach statistical significance on real data — not a biased sample.
Why VWO + Ingest Labs
A/B testing depends on a simple contract: every user who enters an experiment gets counted, and every conversion they generate gets attributed to the right variant. Break either side of that contract and your experiment results are unreliable. Browser-side tracking breaks both — ad blockers suppress conversion events, and ITP resets cookies so returning users look like new ones.
The impact on experimentation is worse than on analytics. In analytics, missing data creates a uniformly smaller sample. In A/B testing, the data loss is non-random — privacy-conscious users, Safari users, and mobile users are disproportionately undercounted. This introduces a systematic bias that can make a winning variant look like a loser, or vice versa.
Ingest Labs solves this by sending conversion events to VWO server-side and maintaining a persistent first-party identity for experiment bucketing. Every user stays in their assigned variant. Every conversion gets counted. Your experiments reach significance faster, and the results reflect reality.

Experiments that reach significance faster — because every conversion is counted and every user stays bucketed.
- Recover conversion events lost to ad blockers — server-side delivery bypasses all browser restrictions
- Maintain consistent experiment bucketing with persistent first-party identity across sessions
- Eliminate non-random data loss that biases experiment results against privacy-conscious users
- Track server-side conversion goals — purchases, sign-ups, and custom events verified by your backend
- Enforce GDPR and CCPA consent at the server level before forwarding events to VWO
- Support both VWO web testing and FullStack server-side experiments from a single event pipeline
Frequently Asked Questions
How does Ingest Labs improve VWO experiment accuracy?
Ad blockers and privacy browsers can block VWO's client-side tracking snippet, causing conversion events to go unrecorded. This skews experiment results — you see fewer conversions than actually occurred, and the bias isn't evenly distributed across variants. Ingest Labs sends conversion events server-side, ensuring VWO receives every goal completion regardless of browser conditions.
Does this replace VWO's SmartCode snippet?
No. VWO's SmartCode handles variation rendering and client-side experiment assignment. Ingest Labs complements it by delivering conversion events (goals) server-side. You keep VWO's visual editor and client-side testing capabilities while gaining reliable server-side goal tracking.
How does first-party identity help with experiment assignment?
Consistent experiment bucketing requires a stable user identifier. When third-party cookies are blocked or first-party cookies expire (Safari ITP caps them at 7 days), VWO may re-bucket returning users into different variations. Ingest Labs provides a persistent first-party identity that keeps users in their assigned variation across sessions.
Can I use this with VWO's server-side testing?
Yes. VWO offers server-side experimentation through their FullStack product. Ingest Labs integrates with both VWO's web testing (SmartCode) and server-side testing, providing a unified event pipeline for goal tracking across both testing modes.
Is this GDPR and CCPA compliant?
Yes. Ingest Labs enforces consent at the server level. Conversion events are only forwarded to VWO when the user has granted the appropriate consent. This is more reliable than browser-side consent enforcement, which can be inconsistently applied across testing variations.
How long does setup take?
Most customers are live with server-side VWO goal tracking in under 24 hours. You connect your VWO account in the Ingest Labs dashboard, map your conversion events to VWO goals, and server-side delivery begins immediately.
