Google Optimize Alternatives for CRO on WordPress Sites

With the sunset of Google Optimize in 2023, WordPress website owners and digital marketers have been actively searching for suitable alternatives to continue their Conversion Rate Optimization (CRO) efforts. Google Optimize has long been a preferred tool for A/B testing and personalization due to its seamless integration with Google Analytics and its user-friendly interface. However, with its discontinuation, the need to explore other powerful and adaptable CRO tools compatible with WordPress has become more important than ever.

Whether you’re an eCommerce brand, a blogger, or a corporate website owner, finding the right CRO tool is critical to continuously improving your site’s performance. Below are some of the best alternatives to Google Optimize for WordPress sites, each offering their own strengths in terms of functionality, affordability, and compatibility.

1. Optimizely

Enterprise-grade A/B testing and personalization

Optimizely is one of the most well-known names in the CRO industry. Formerly known as “Google Optimize’s primary competitor,” Optimizely offers highly advanced experimentation solutions, allowing teams to run A/B tests, multivariate tests, personalization campaigns, and more.

• Advanced experimentation workflow
• Robust targeting and segmentation options
• Integrates with WordPress via plugins and custom code

The downside? Optimizely comes with a steep price tag, making it ideal for enterprise users rather than small businesses or bloggers.

2. VWO (Visual Website Optimizer)

All-in-one platform for qualitative and quantitative CRO

VWO is a comprehensive alternative to Google Optimize, designed to deliver insights and testing capabilities in one package. It offers heatmaps, recordings, surveys, A/B testing, multivariate testing, and server-side tests.

• No-code visual editor for A/B testing
• WordPress compatibility via script integration
• Strong analytics and reporting dashboards

VWO’s pricing is more transparent and flexible than Optimizely’s, which makes it more accessible to medium-sized organizations and advanced marketers.

3. Convert

Privacy-first CRO solution with deep integrations

Convert is an A/B testing tool focused on privacy and performance. It’s a great Google Optimize alternative because it supports easy integration with WordPress and prioritizes compliance with GDPR, CCPA, and other privacy laws.

• Built for speed and data privacy
• Supports JavaScript code-based experiments
• Integrates with most CRM and CMS systems

Convert is ideal for marketers who prioritize ethical data use and want to avoid invasive tracking tactics. The platform is developer-friendly and scalable for growing businesses.

4. Nelio A/B Testing

Specifically designed for WordPress users

Nelio A/B Testing stands out as one of the best Google Optimize replacements for WordPress users due to its native integration. You don’t need to touch a single line of code – experiments are launched, managed, and analyzed directly from the WordPress dashboard.

• WordPress-native plugin
• Test headlines, images, themes, and more
• Real-time reporting and heatmaps included

The intuitive interface and seamless compatibility with WordPress themes and page builders (like Elementor and Gutenberg) make it a top choice for non-technical users.

5. Split Hero

Simple, fast A/B testing for marketers and freelancers

Split Hero is a minimalist A/B testing tool intended for WordPress professionals who don’t need enterprise-level complexity. It supports landing page tests and tracks metrics like bounce rate, conversions, sessions, and performance over time.

• Clean, user-friendly dashboard
• Perfect for agencies and freelancers
• Supports up to 5 client sites on basic plan

Split Hero’s simplicity and affordability make it ideal for solo marketers, designers, and small businesses seeking to boost performance through iteration.

6. A/B Smartly

Developer-friendly A/B testing with robust APIs

For businesses that need high levels of control and customization, A/B Smartly is a solid alternative. The platform allows developers to run server-side A/B tests and integrate with their existing stack using a simple JavaScript SDK or extensive APIs.

• High-performance testing ideal for SaaS and tech startups
• Parallel experiments to shorten testing cycles
• Efficient and scalable infrastructure

Unlike other tools on this list, A/B Smartly is better suited to data teams, engineers, and product developers who treat experimentation as a core part of their product pipeline.

7. Crazy Egg

Focus on heatmaps with A/B testing capabilities

Crazy Egg combines visual analytics with testing, giving marketers a better understanding of user behavior. While best known for its scrollmaps, clickmaps, and recordings, Crazy Egg also includes a built-in A/B testing tool that works well with WordPress.

• Visual page tools that simplify optimization
• Easy installation via plugin or code snippet
• Affordable alternatives for smaller sites

Although not as robust as VWO or Optimizely in terms of experimentation, Crazy Egg shines in helping teams diagnose problems visually before testing solutions.

Choosing the Right Google Optimize Alternative

The ideal tool depends on your team’s workflow, technical abilities, and conversion goals. Here’s a quick guide for different scenarios:

• For enterprise needs: Optimizely or VWO
• For WordPress-first users: Nelio A/B Testing
• For freelancers and agencies: Split Hero
• For developers: A/B Smartly or Convert
• For visual analytics: Crazy Egg

It’s important for teams to evaluate pricing models, testing features, user interface ease, and privacy compliance before committing to a platform. Testing is not just a feature—it’s a process, and the tool you use should align with your resources and business goals.

Nelio A/B Testing is the most straightforward solution for WordPress users and requires no coding. It works directly inside the WordPress admin interface.

Extremely important. Tools like Convert are privacy-first and make it easier to comply with data regulations like GDPR and CCPA. Always ensure your tool aligns with your users’ privacy rights and local laws.

In the wake of Google Optimize’s closure, WordPress site owners have numerous A/B testing and CRO tools to choose from based on their specific needs. With the right solution, continued optimization of conversion performance remains not only possible but potentially even more powerful.
