Create a Test Safely
- Start with a single, high-impact page (homepage or product page)
- Choose a test type: Visual change, Split URL, or Offer (early alpha)
- For visual changes, use the visual editor to point and click—or type CSS selectors manually if you prefer
- Keep each variant focused so results are easy to interpret
- Preview first, then start the test
Overlapping tests are blocked by default
Multiple tests on the same page can interfere and make results unreliable, so Zolvio blocks starting an overlapping running test by default. Run tests on different pages, or finish one before starting another on the same page.
Consent and Exclusions
A/B testing should respect excluded paths (such as checkout-like routes). If your store requires consent, see Cookie & Consent.
