Question 1

What is the difference between split URL testing and A/B testing?

Accepted Answer

Standard A/B testing modifies elements on the same URL. Split URL testing redirects visitors to an entirely different URL, making it the right choice for testing full redesigns, different page frameworks, new tech stacks, or structural changes that can't be achieved with on-page edits alone.

Question 2

Does split URL testing impact site speed or SEO performance?

Accepted Answer

No. Our redirect logic is processed before the page renders, so visitors experience no delay. Canonical tags are automatically managed to prevent duplicate content issues, and we use temporary 302 redirects to preserve your original page's full SEO authority.

Question 3

Do I need a developer to set up split URL tests?

Accepted Answer

No. You can configure a split URL test entirely through our platform—set your URLs, define your audience and traffic split, and launch. The only prerequisite is that your variation URL is already live and accessible. For more complex server-side setups, our code editor and managed service team are available.

Question 4

Will visitors notice a delay or flicker during the redirect?

Accepted Answer

No. Our high-speed snippet makes the redirect decision before any page content renders, so visitors are routed to their assigned variation seamlessly—with zero visual flash, layout shift, or perceivable delay.

Question 5

Will my UTM parameters and ad tracking stay intact?

Accepted Answer

Yes. Our platform automatically carries over all URL parameters—including UTMs, GCLIDs, and custom tracking parameters—across the redirect. Your paid campaign attribution and analytics data remain fully accurate.

Question 6

Can I test variations across different sub-domains or platforms?

Accepted Answer

Yes. Split URL testing supports redirects to any accessible URL—including different sub-domains, staging environments, or entirely separate platforms. This makes it ideal for testing platform migrations or comparing different tech stacks head to head.

Question 7

What happens if the experiment URL returns an error or 404?

Accepted Answer

Our failover protection automatically detects URL errors and redirects affected visitors back to the original page instantly. No visitor will ever hit a dead end during a live experiment.

Question 8

How do you handle user persistence across different sessions?

Accepted Answer

Once a visitor is assigned to a variation, they stay on that variation for the duration of the experiment—even if they close their browser and return days later. This ensures clean data and a consistent experience for every participant.

Question 9

How does the platform handle caching?

Accepted Answer

Our redirect logic operates at the script level before any page content is cached or rendered, so browser and CDN caching do not interfere with variation assignment. Visitors are always routed to the correct version regardless of their cache state.
