Top 10 Google Optimize Alternatives in 2025 (Find a Replacement for Google Optimize After Its Sunsetting)

Testing out your new webpages and marketing campaigns is essential for ensuring that you’re getting the best possible results. 

When you’re thinking about what you’ll use to replace Google Optimize, you should think about the kinds of tests you usually run and the features you’ll need.

Step 1: Take note of the features you love in Google Optimize

Google Optimize has an impressive number of features that marketers have loved because of their power and ease of use. Even beginners could quickly understand how to use the service and start running experiments to improve the website experience.

The visual website optimizer allowed users to quickly and easily create variants using the “What See Is What You Get” (WYSIWYG) editor.

Then, you could use the simple integration with Google Analytics to confidently choose which one led to the best digital experiences for your customers.

Step 2: List the features you thought were missing from Google Optimize 

Although Google Optimize was a great tool, it wasn’t perfect. 

That’s part of why Google chose to discontinue the service, as they write in their announcement, “though a longstanding product, [Optimize] does not have many of the features and services that our customers request and need for experimentation testing.”

There are many powerful features that were never available on Google Optimize (including tests of longer-term marketing outcomes and website personalization), some of which we’ll explore in our list of the best alternatives.

There were also other issues with the free service, like:

• A limit on the number of tests you could run at once
• Problems with detecting flicker upon website loading
• A lack of customer support

As you start thinking about a tool to replace Google Optimize, keep in mind that this is the perfect opportunity to upgrade to features you might have missed out on. Make a list of the most important features you want your testing tool to have. 

Step 3: Make a list of your desired features and use it to evaluate your options

Once you know which Google Optimize features you want to keep using and which new features you’d like to access, take a look at our list of alternatives below to find the best testing software for your needs.

For example, you might want to find a tool that does a great job of measuring certain key performance indicators (KPIs) like conversion rate or sales. Stores that use website personalization might want to A/B test the results of their advanced targeting of different customer segments.

Ideally, you’ll find a tool that has all or most of the features you need.

Step 4: Test them out 

If you’re interested in more than one tool on this list, it’s a good idea to test them out to see which one works best for you. 

Some of the experiment software we’ve listed offers a free plan or a free trial, so you can try before you buy.

Since A/B testing and experimentation are so important for optimizing your website experience, you’ll want to make sure that you pick a tool that does everything you need.
