Run rigorous A/B tests and personalize every visit on Shopify or any storefront โ no engineers required.
Google Optimize was shut down in September 2023, leaving millions of websites that had relied on it for free A/B testing without a replacement. Three years later, in 2026, the market has consolidated around clear alternatives โ some free-ish, most paid, and a handful genuinely purpose-built for ecommerce. This guide ranks the best Google Optimize alternatives based on how they perform for the most common use cases: ecommerce optimization, landing page testing, and general website CRO.
Google Optimize's appeal was simple: it was free, integrated natively with Google Analytics, and had a basic visual editor that non-developers could use. Its limitations were also real:
When it shut down, the vast majority of its users were small and mid-size businesses who needed something affordable, simple, and connected to Google Analytics. The alternatives below address that need at various price points.
| Tool | Best For | Starting Price | GA4 Integration | Shopify Support |
|---|---|---|---|---|
| CustomFit.ai | Shopify D2C ecommerce | $99/mo | Yes | Native |
| VWO | General website optimization | $199/mo | Yes | Partial |
| Convert.com | Privacy-conscious teams | $199/mo | Yes | Partial |
| Unbounce | Landing page testing | $99/mo | Yes | No |
| Crazy Egg | Heatmaps + basic testing | $49/mo | Yes | No |
| AB Tasty | Mid-market brands | ~$2,000/mo | Yes | No |
| Microsoft Clarity | Free heatmaps only | Free | Partial | No |
Google Optimize was never purpose-built for ecommerce. CustomFit.ai fills that gap for Shopify brands with native integration, ecommerce-specific metrics, and no-code operation.
Why it's the top alternative for ecommerce: Google Optimize required you to manually set up conversion goals (usually via GA events) to track ecommerce metrics. CustomFit.ai tracks add-to-cart, conversion rate, AOV, and RPV automatically โ no setup required โ because it reads directly from Shopify's event stream.
The visual editor is significantly more capable than Google Optimize's editor. You can modify any element on your product pages, collection pages, homepage, and cart โ and preview changes on your actual store before going live.
Key advantages over Google Optimize:
Pricing: $99/month Starter, $249/month Growth. 14-day free trial, no credit card required.
Best for: Shopify ecommerce brands that want to replace Google Optimize with something more powerful but still accessible to non-developers.
VWO is the most popular paid Google Optimize replacement and for good reason โ it covers the full range of optimization tools (A/B testing, multivariate, split URL, heatmaps, session recordings) in one platform.
Key strengths:
Pricing: $199/month for basic testing, scaling with traffic. Heatmaps and session recordings require higher tiers.
Best for: General website optimization teams who want a comprehensive CRO tool and don't need Shopify-specific features.
Limitation: For pure Shopify optimization, VWO requires workarounds that CustomFit.ai handles natively. See our full VWO alternatives guide for context.
Convert.com was one of the first "GDPR-friendly" A/B testing platforms. It doesn't collect or share visitor data with third parties, uses session-based tracking without persistent cookies by default, and stores data in EU infrastructure.
Key strengths:
Pricing: $199/month for 800k monthly tested users.
Best for: Brands with European audiences or strict data compliance requirements. Also good for CRO agencies managing multiple client accounts.
Limitation: Developer involvement needed for most non-trivial tests. Not plug-and-play for ecommerce without technical support.
Unbounce is a landing page builder with built-in A/B testing. It doesn't optimize your existing website โ instead, you build landing pages in Unbounce's drag-and-drop editor and test variants there. If you're running Google Ads or Meta campaigns to dedicated landing pages, this is a strong choice.
Key strengths:
Pricing: $99/month (Build), $149/month (Experiment with A/B testing).
Best for: Performance marketing teams who want to test multiple ad landing page variants quickly.
Limitation: Can't optimize your main Shopify store โ only standalone landing pages. Not a full Google Optimize replacement for on-site testing.
Crazy Egg combines heatmap analysis, session recordings, and basic A/B testing at an accessible price point. For teams that primarily used Google Optimize for small-scale testing and want to add research capabilities, Crazy Egg is a reasonable upgrade.
Key strengths:
Pricing: $49/month (Basic), $99/month (Standard), $249/month (Plus).
Best for: Small ecommerce teams in early stages of CRO who want research tools alongside basic testing.
Limitation: A/B testing capabilities are limited. Not suitable as a primary testing platform for a serious experimentation program.
Microsoft Clarity is worth mentioning because it's free and includes heatmaps and session recordings โ features Google Optimize never had. However, it has no A/B testing capabilities whatsoever.
Key strengths:
Pricing: Free.
Best for: Supplementing your A/B testing tool with free heatmap research. Use it alongside CustomFit.ai or VWO.
Limitation: Not an A/B testing tool at all. Cannot replace Google Optimize for experimentation.
Most D2C brands that used Google Optimize need two things: a way to understand where visitors drop off (research), and a way to test fixes (experimentation). Here's the recommended stack at different budget levels:
Budget tier (under $100/month): CustomFit.ai Starter ($99/month) + Microsoft Clarity (free). You get native Shopify A/B testing and AI personalization alongside free heatmap research.
Growth tier ($100โ$300/month): CustomFit.ai Growth ($249/month) for testing and personalization, with GA4 for behavioral analytics.
Scale tier ($300+/month): CustomFit.ai + a dedicated data analytics tool (like Mixpanel or Amplitude) for cohort analysis and LTV tracking.
