Testing at Scale

Every test generates data. Even archived tests aren't failures — they're learnings that refine our next hypotheses.

Completed / Archived
Archived tests are a natural part of the optimization process. Each one eliminates a hypothesis and focuses traffic on the ideas that actually move the needle. A portfolio that never archives tests isn't testing aggressively enough.

5 Tests Approaching Significance

These tests show strong positive improvement in Add-to-Cart rate. They need 2–4 more weeks of data to reach statistical significance.

04 — Next Phase

The Next 4–6 Weeks

Five tests are approaching significance. Here's what the next phase focuses on to turn these signals into confirmed wins.

Immediate Priorities
  1. Bring VETS-29 and the 4 other promising tests to 95% statistical confidence — estimated 2–4 weeks
  2. Declare winners and implement the winning variations permanently on vetsak.com
  3. The newest batch (VETS-60 through VETS-70) is already running — directly leveraging insights from 31 earlier experiments
  4. Continue disabling losers in real-time to protect conversion rate while tests mature
VWO License — Upgrade to Paid Plan
  1. Needed to implement confirmed winners, continue optimization, and expand testing scope
  2. German market opportunity: Apply proven winners from vetsak.com directly to vetsak.de — instant wins, no re-testing needed
  3. Every winner found on .com can be deployed to .de immediately = 2× the value from the same research
  4. VWO cost is trivial compared to potential revenue from a +17% ATC winner deployed across both domains
05 — How to Improve Results

Actionable Next Steps

Recommendations to increase test velocity and win rate going forward.

Increase Traffic Allocation
Many tests run at low traffic %. More traffic = faster results = more tests per month. Shorter test cycles mean more learnings.
Focus on High-Impact Pages
Homepage tests get the most traffic and are showing wins. Prioritize homepage over PDP/collection pages for faster significance.
Fewer Variations Per Test
Tests with 10 variations split traffic too thin (VETS-29 needed 28 days). 2–3 variations can reach significance in 7–10 days.
Revenue as Primary Metric
Switch from ATC to Revenue tracking in VWO (requires ecommerce integration). ATC wins that don't convert to revenue aren't real wins.
Pre-Test with Heatmaps
Use VWO Insights to identify friction points before designing tests. More targeted hypotheses lead to higher win rates.
Iterate on Winners
When a test wins, iterate on the winner rather than starting fresh. VETS-29 V5 wins → next test refines V5 further for compounding gains.
