Nelio A/B Testing Setup Screen

Once accepted, click Continue.

2. Explore the Welcome Experience

After accepting the Terms of Service, you’ll be taken to the Welcome screen.

The Welcome experience is designed to help you launch your first meaningful test as quickly as possible.

Temporary Quota Boost

If your website is publicly accessible and you’re a new user, Nelio A/B Testing automatically increases your available quota during your first 14 days.

This temporary quota boost gives you more room to:

  • Run real tests.
  • Collect enough traffic to obtain meaningful results.
  • Evaluate Nelio A/B Testing without immediately reaching the free plan’s monthly quota.

The additional quota is applied automatically—no configuration is required.

AI-Powered Test Recommendations

One of the biggest challenges when starting with A/B testing is deciding what to test first.

To help you get started, Nelio A/B Testing analyzes your homepage and suggests a selection of optimization opportunities tailored to your website.

Currently, recommendations focus on CSS and Text Tests, which are among the simplest and most effective tests you can run. Typical suggestions include improving headlines, refining calls to action, updating copy, or making small visual changes that may increase conversions.

When you choose one of the proposed ideas, Nelio automatically creates the corresponding test for you, allowing you to start optimizing with just a few clicks.

3. Continue to the Overview

Once you’ve completed the Welcome experience, you’ll arrive at the Overview page.

From there, you can:

  • Review your current quota and subscription status.
  • Monitor your Optimization Score.
  • Discover additional testing opportunities.
  • View your running and recently completed tests.
  • Create new tests whenever you’re ready.

Privacy and Data Processing

Nelio A/B Testing processes test data in Nelio Cloud.

The plugin is designed to support GDPR, CCPA, and similar privacy regulations. Analytics data is processed without collecting personally identifiable information from your visitors as part of normal test tracking.

If your website requires visitor consent before analytics are collected, you can configure Nelio A/B Testing to wait for consent before tracking events.

Troubleshooting

I don’t see the “Add New Plugin” option.

Your WordPress account probably doesn’t have permission to install plugins. Contact your site administrator.

The plugin won’t activate.

Verify that your WordPress installation meets the minimum supported WordPress and PHP versions.
