Every other WordPress A/B testing tool makes a trade: swap content in the browser and your visitors see it happen, or split traffic across URLs and Google sees it happen. Spliteezy refuses the trade — the decision is made in PHP, on your server, before the first byte leaves.

Client-side & redirect tools
—Visitors catch a flash of the original before the variant swaps in
—Extra JavaScript on every page drags down Core Web Vitals
—Variant URLs pile up — Google indexes them, then they 404
—Results muddied by bots, cache mismatches and slow swaps
The Spliteezy way
The right version ships at first byte — nothing swaps, nothing blinks
Zero JavaScript in the critical rendering path
One URL per page — before, during and after every test
Deterministic assignment: the same visitor always sees the same version
Not at all. You edit your variant the same way you edit any WordPress page or post — with the builder you already use. Spliteezy handles everything else behind the scenes: splitting traffic, tracking goals, and crunching the numbers.
Will A/B testing slow down my website?
No. Spliteezy picks the right version on the server before your page loads, so there's nothing extra running in your visitors' browsers. Your site speed, Google rankings and Core Web Vitals stay exactly as they are.
What does “no flicker” actually mean?
Most testing tools load your original page, then quickly swap it for the variant with JavaScript. Visitors briefly see the wrong version before the right one appears — that flash is the “flicker”. Spliteezy serves the correct version from the very first byte, so nothing ever blinks or shifts.
How long does a test need to run?
It depends on your traffic. Spliteezy shows you a live confidence score and only suggests calling a winner when the result is statistically reliable — usually after a few hundred visitors have seen each version. On a busy site that can happen in a day or two.
Can I test WooCommerce products and custom post types?
Yes. Spliteezy works on any public WordPress content — posts, pages, WooCommerce products, landing pages and custom post types. You can track conversions all the way through to a checkout or thank-you page.
What happens when a test ends?
Click Apply and the winning version becomes the live page for everyone — instantly. Or keep the original and go back to where you started. Either way the test closes cleanly: no leftover variant URLs, no dead links, no 404s to chase down.
