Which plan unlocks a landing page A/B test

The clicks are already paid for. You can publish the page on a cheap plan and still need a more expensive plan before a test will run.

Landing page split testing at Unbounce, Instapage and Leadpages starts on Experiment, Optimize or Grow. Those are the tiers that include testing. Pick the one that matches your traffic, and decide whether the pay step has to sit inside the experiment.

My take

I'd start with Unbounce's Experiment plan if the page is all you need to test and your traffic stays under the cap. Skip the cheaper tiers that only publish. Instapage Optimize is my choice for server-side variants. I'd use Leadpages Grow for page testing if a visitor cap would be a problem. ClickFunnels is where I'd go when the checkout has to be in the test.

Why the ad URL matters here

Google Optimize and Optimize 360 were no longer available as of September 30, 2023. Experiments that were still running ended that day. The landing page A/B testing tool you pay for now is the replacement for that layer.

The headline is the line you want to change, and the address already in the ad is the one worth keeping. A variant on its own URL becomes a new destination, so look for a test that keeps the campaign link before you compare editors.

Builders for page tests only

A landing page A/B testing tool, when the page is the whole job, is one of three hosted builders. I would judge each one by the plan that includes testing, by the visitor meter, and by what long-term users say about the editor.

On a small ad budget, that monthly fee eats a large part of what you spend on ads, and you pay it before you have a winner. Public threads about these builders treat a fee in this range as hard to justify while spend is still small.

Unbounce's homepage leads with the builder. A/B testing shows up on the pricing page as its own plan.

Unbounce's pricing page lists unlimited A/B testing on the Experiment plan. Cheaper tiers publish the page. The A/B testing product page advertises unlimited tests and unlimited page variants. Unlimited tests are what Experiment advertises.

People who have used the editor say recent updates made it slower and heavier, and some are planning to move their pages. That is the tradeoff if Experiment is the plan you can afford.

Past the Experiment visitor cap, Unbounce bills an overage. The Unbounce review goes further, and so do the pricing breakdown and the alternatives.

Instapage's homepage shows the editor. Server-side tests are listed on Optimize, not on Create.

Instapage's plans page lists server-side A/B testing on Optimize. The plan copy says you can test several variants with no flickering, and change the traffic split with no page-load delay. Create is the publishing plan, with a visitor allowance. A/B testing is on Optimize.

Instapage

Optimize, yearly (16 Oct 2026): $159/mo, 30,000 unique visitors, server-side tests
Optimize, monthly (16 Oct 2026): $199/mo
Create, yearly (16 Oct 2026): $79/mo, 15,000 unique visitors, no A/B testing

For a page-only test when you want server-side variants on Optimize.

Instapage plans

Leadpages' homepage leads with a campaign prompt. Manual testing is on the Grow plan.

Leadpages' pricing page puts manual A/B testing on Grow, with up to six variants on a page. Pro and Business are publishing plans. The same page states there is no traffic cap on any plan.

Leadpages

Grow, yearly (16 Oct 2026): $67/mo, manual A/B, six variants per page
Traffic: No cap on any plan
Publishing plans: Pro and Business are publish-only

For a page-only test when you do not want a traffic meter.

Split testing software at checkout

A landing-page builder sends the buyer on to Stripe or another cart, and the test ends at the form. Order bumps, upsells, and the pay step sit outside it.

ClickFunnels homepage on a dark background, with a headline about a first $10k month, an email field, and tabs for funnel, store, CRM, email and courses. — ClickFunnels' homepage leads with the funnel account. The A/B page covers steps, pages and email.

ClickFunnels' A/B testing page says you can run tests on landing pages, funnels, and emails from the same account. That page names no plan. The ClickFunnels review covers the rest of the account.

SamCart puts A/B tests on Pro. Core is the plan without them. The SamCart review covers that split.

ClickFunnels

What the feature page covers: Landing pages, funnel steps, and email
Which plan includes it: The feature page does not say

For a test that has to include a funnel step, not only the landing page.

What to change first on paid traffic

Start with the offer headline, the line the ad already promised. Proof beside the hero comes next, then the button above the fold. The checkout path is last, and only when the tool keeps that step inside the experiment.

A short run with few clicks can call the wrong headline the winner. None of these vendor pages says how many clicks a test needs, so you decide how long it runs.

If you have not chosen a tracker, a checkout, or a video player yet, the stack picker matches those three to the offer.
