Google Optimize alternatives
Google Optimize was shut down on 30 September 2023. If you ran landing page tests with it, you need something else. This guide explains what to look for, compares the main options, says where Twinpage fits and where it does not, and shows how to run a first test.
What happened to Google Optimize
Google shut down Optimize and Optimize 360 on 30 September 2023. Google said it would invest in other solutions and improve how Google Analytics 4 works with third-party testing tools. It did not name one replacement, so you choose a testing tool and keep using Google Analytics 4, or another analytics tool, to measure the rest of your site. Source: Google Optimize Help Center.
What to look for in a replacement
- How you set up a test. Some tools give you a visual editor, some ask you to write code or use a software development kit. Pick the one your team will actually use.
- How you are charged. Vendors charge per visitor, per event, per seat or by contract. Work out your monthly traffic first, then compare what each would cost at that number.
- Whether you can trust the result. Look for a stated significance test, a minimum sample before a winner is called, and a warning when traffic is not split as planned.
- Page flicker. Tools that change the page in the browser can show the original version for a moment. Ask how the tool prevents that.
- Your data. Check where results are stored and whether visitor data is stored in the visitor's browser (consent rules may apply).
- Limits. Check how many tests can run at once, how many projects you get and what happens when you go over your traffic limit.

Where each tool fits
- Optimizely Web Experimentation (visual editor or custom code): Teams that want experimentation as part of a wider digital experience platform.
- VWO Testing (visual editor or code editor): Marketing teams that want testing next to other conversion research tools.
- AB Tasty (visual editor or custom code): Marketing and ecommerce teams that want testing and personalization in one tool.
- Convert Experiences (visual editor or code editor): Marketing teams and agencies that run tests on websites.
- GrowthBook (SDK in your code, or a visual editor for web pages): Product and engineering teams that want feature flags and experiments, with the option to self-host.
- PostHog Experiments (feature flags in your code): Product and engineering teams that already use PostHog for analytics.
Where Twinpage fits
Twinpage is for marketers, founders and small teams who want to test a page without a sales call or a developer. You add one script tag, choose what to change, pick one goal and read the result.
- Free plan: 10,000 tested sessions a month, 1 project and 1 running experiment.
- Starter plan: $49 a month plus applicable tax for 50,000 tested sessions, 3 projects and 5 running experiments.
- Growth plan: $99 a month plus applicable tax for 200,000 tested sessions, 10 projects and 15 running experiments.
- No verdict before 1,000 exposures and 25 conversions per variant.
- Soft cap at 125% of the monthly tested sessions: experiments pause until the next month or an upgrade.
Twinpage does not have these yet, so pick another tool if you need them: teams and roles, tests on mobile apps or on your server, and languages other than English.
Run your first test in about ten minutes
- Create an account and a project for your website.
- Copy the install script tag into your site's head and use the installed check to confirm it is working.
- Create a test: choose the pages it runs on, choose what to change (in the visual editor, or with text, CSS, a redirect to another URL or, on Growth, your own JavaScript) and pick one goal (a click, a page view or a custom event).
- Start the test. Traffic is split evenly between the original and your variants, up to 5 versions in all depending on your plan, and each visitor keeps the same version.
- Read the results. Twinpage waits for at least 1,000 visitors and 25 conversions per version before it calls a winner, and warns you if traffic is not split evenly.
Frequently asked questions
Can I still use Google Analytics with a new testing tool? Yes. Testing tools measure the test; Google Analytics 4 can keep measuring the rest of your site.
Do I need a developer? For Twinpage you need to paste one script tag into your site's head. After that you can create tests in the dashboard.
How much traffic do I need? Enough that each version gets at least 1,000 visitors and 25 conversions. With less than that, the result is not reliable and Twinpage tells you to keep running.
