1

Install Optibase

Install Optibase with the Webflow App or add one script to your site. The app connects your project automatically, and the script works on every page without extra setup. You only need to install it once, even if your split test uses many URLs or landing pages. After this, your site is ready for testing.

2

Create your page variants

Build each version of your page in Webflow as its own URL. You can make as many variants as you want with different layouts, styles, or full flows. There is no extra setup needed on any page. Once your pages are ready, you connect their URLs in Optibase and use the same goals for all variants.

3

Set your conversions

Choose how you will measure success for your split test. You can track clicks, form submits, page views, scroll depth, time on page, or custom events. Mark elements with the Webflow App or add IDs yourself. All variants share the same goals, so each page is judged in a fair and clear way.

4

Choose audience and traffic split

Pick who should see each version of your test. You can target visitors by location, screen size, browser, or operating system. Set a manual split if you want full control, or let AI pick the best mix for you. Your variants are already in the Webflow Designer, so you know exactly what each visitor will see.

5

Run your test

Turn your split test on with one click in Optibase. Traffic begins flowing to each page right away with no redirects or slowdowns. UTMs stay intact for paid campaigns, and every visit is tracked cleanly across all URLs. You can watch the live status at any time and let auto-stop rules end the test when a winner appears.

6

Analyze results

See how each page performs as your test runs. Optibase shows clear results for clicks, forms, views, and full flows across every URL. Reports help you spot the winning page and understand why it works. You can also send your data to GA4, Mixpanel, HubSpot, or any other tool using our API.

Heatmaps

See where users click, scroll, and focus. Heatmaps help you understand behavior so you know what to test and what to improve next.

User recordings

Watch real sessions to see how people use your site. Spot friction, confusion, and missed clicks that numbers alone can’t show.
FAQ

Frequently asked questions

What is split testing?
Split URL testing is a way to compare two or more different pages using separate URLs. Each visitor is sent to one page version, and you measure which page performs better. It is often used to test new landing pages, full designs, or complete flows where changes are too big for simple A/B tests.
What is the difference between split URL testing and A/B testing?
A/B testing compares different versions of the same page on one URL. Split URL testing compares completely different pages on separate URLs. A/B tests are best for small changes like copy or buttons. Split URL tests are better for big changes like new layouts, landing pages, or full signup flows.
Can I test two completely different page layouts?
Yes. Split URL testing is made for this. You can test two or more pages with completely different layouts, designs, and content. Each version has its own URL, so you can compare full page ideas, new landing pages, or different flows and see which one works best.
Does split URL testing impact SEO?
No. Split URL testing with Optibase does not harm SEO. Each page loads on its own URL with no redirects, flicker, or blocked content. Search engines can crawl pages normally, and page speed stays fast. This makes split URL testing safe for SEO, even when testing full pages or important landing pages.
How do you split URL test a page in Webflow?
To split URL test a page in Webflow, first create separate page versions in the Webflow Designer, each with its own URL. Then install Optibase using the Webflow App or one script. Add the page URLs in Optibase, choose your conversion goals, and set how traffic is split. Optibase sends visitors to each page and tracks which one performs better.
Does split URL testing affect performance?
No. Split URL testing with Optibase does not affect performance. Pages load on their own URLs with no redirects or delays. There is no flicker, and your site speed stays the same. This makes split URL testing safe for user experience, SEO, and paid traffic, even when testing full pages or flows.
Do I need a developer?
No. You do not need a developer to run split URL tests with Optibase. You create your page versions in the Webflow Designer like you normally do. Then you add the page URLs in Optibase and start the test. There is no code to write and no developer help needed.
Is split URL testing included in the free plan?
Yes. Split URL testing is included in the Optibase free plan. You can install Optibase, add your page URLs, run split tests, and track results without paying. The free plan is a good way to try split URL testing on your site before upgrading for more traffic and advanced features.
