Why Do I Always See the Original Version of My Tests?

If you always see the original version of a test, this doesn’t necessarily mean something is wrong.

Once a visitor is assigned a variant, Nelio A/B Testing keeps showing that same variant on future visits. The assignment is stored in a cookie to provide a consistent experience. So, if you were assigned Variant A (the original), you’ll continue seeing it.

If you want to check other variants or verify that your test is working correctly, see “How do I check if Nelio A/B Testing is working properly?”

Common reasons why you see only the original

1. You were assigned the original variant (Variant A)

This is normal behavior. Once you’ve been assigned Variant A, Nelio A/B Testing will continue showing you that variant on subsequent visits.

2. You’re logged in as an admin

Admin users are excluded from tests by default. Try visiting the site while logged out or using an incognito/private browsing window.

3. Segmentation rules exclude you

If your test uses segmentation, you may not meet the conditions required to participate. Check the segmentation rules configured for the test.

4. Caching or CDN interference

Cache tools may serve the same version of a page to everyone. Try clearing or purging:

• Your WordPress cache
• Any CDN (Cloudflare, Akamai, Fastly, etc.)
• Your browser cache

5. Your Theme is Missing wp_head() or wp_footer()

Nelio A/B Testing relies on standard WordPress hooks to load the scripts it needs. If your theme doesn’t include wp_head() and wp_footer(), tests may not work correctly. Check if our public.js script shows up in your tested page.

6. Your site is not using HTTPS

Nelio A/B Testing requires HTTPS. It will not run on HTTP-only websites.

7. A plugin or theme conflict

Occasionally, another plugin, theme, or site configuration may prevent a test from working correctly.

You can use Nelio A/B Testing’s Debug Tools to check the tracking status, variant loading, active tests, and events on the current page.

Occasionally, a compatibility issue might block tests from running. If you suspect this, contact our support team — we’re happy to help.
