Why Do I Still Have No Results in My Test?

You should normally start seeing views and conversions after starting a test and receiving eligible traffic. If your results remain empty, one or more of the following issues may be the cause.

1. You’re Logged In as an Admin (Admins Are Not Tested)

Nelio A/B Testing does not include admin or editor users in tests. If you browse your site while logged in, your visits and actions will not appear in the results. To test it as a “regular visitor”, you can either log out, use a different browser, or open your site in incognito/private mode.

2. Your Site Is a Staging/Testing Environment

If Nelio A/B Testing detects that your site is a staging environment, tracking events aren’t sent to Nelio Cloud. This lets you validate your tests without consuming quota or affecting your actual test results.

In Nelio A/B Testing 8.3 and later, the built-in Debug Tools display a debug panel while your site is in Staging Mode. You can use it to check whether your test is active, whether you’re participating in it, which variant you’ve been assigned, and whether page views and conversions are being detected correctly.

See Using the Debug Tools and How Does Nelio A/B Testing Work with Staging and Live (Testing/Production) Environments? for more information.

3. The Tested Visitors Setting Excludes You

The global Tested Visitors setting determines what percentage of visitors are eligible to participate in tests.

If it’s set below 100%, some visitors won’t participate in any running test. These visitors see the original content and don’t contribute data to the test results.

4. Segmentation Rules Exclude You

If your test uses segmentation, only visitors who meet the configured conditions can participate.

Check the test’s segmentation rules to make sure the visitors you expect to participate actually match them.

5. Your Quota Has Been Exhausted

If you’ve exhausted your available Tested Page View quota, your tests can continue displaying variants, but Nelio A/B Testing stops recording new views and conversions until quota becomes available again.

You can check your current quota from Nelio A/B Testing → Account.

6. Cache or CDN Is Serving Cached Pages

Caching may interfere with testing if visitors receive an outdated cached version of a page or its scripts.

Try clearing or purging:

• Your WordPress cache
• Your CDN cache
• Any other server-side caching layer

If you use a caching plugin or CDN, see How Nelio A/B Testing Works With Cache Plugins and CDNs for more information.

7. Your Theme Is Missing Required WordPress Hooks

Nelio needs your theme to call wp_head() in the header and wp_footer() in the footer.

If these are missing, Nelio will not be able to include its alternative-loading and tracking scripts on your tested pages and no results will appear.

Make sure Nelio’s scripts are present on the tested page while browsing it in incognito mode.

If they’re missing, tweak your theme accordingly or contact your theme developer and ask for help.

8. You Use OptimizePress for Page Design

Nelio A/B Testing is compatible with OptimizePress, but OptimizePress disables third-party plugin scripts by default.

If you’re testing an OptimizePress page and aren’t receiving views or conversions, make sure Nelio A/B Testing’s scripts are enabled in OptimizePress.

Refer to the OptimizePress compatibility FAQ for more info.

9. There Is a Plugin or Theme Compatibility Issue

A theme, plugin, security tool, or custom configuration may occasionally prevent Nelio’s testing or tracking scripts from working correctly.

If you’ve checked the causes above and still aren’t receiving results, use the debug tools to gather more information and contact us if you need help diagnosing the issue.

Summary

If your test has no results, check that:

1. You’re testing as an eligible visitor.
2. Your site isn’t operating in staging mode.
3. The global Tested Visitors setting isn’t excluding you.
4. Your test’s segmentation rules allow you to participate.
5. You still have available quota.
6. Your cache or CDN isn’t interfering.
7. Your theme includes the required WordPress hooks.
8. Third-party tools such as OptimizePress allow Nelio’s scripts to run.
9. No plugin, theme, or custom configuration is blocking testing or tracking.
