Homepage Sticky CTA: +20.4% Conversion Rate for a Whisky Subscription Brand

The highest-intent moment on a long homepage often happens nowhere near the original button.

For an Australian whisky subscription brand, the homepage explained the club, the delivery rhythm, and the product experience across a long scroll. That education was necessary. The problem was that by the time visitors understood the offer, the primary CTA had disappeared far above them.

We added a persistent sticky CTA to the mobile homepage. Result: +20.4% conversion rate with 95.1% probability to beat the control, translating to +A$7,632/month in estimated revenue.

The Decision Point Was Below the Button

The control homepage was doing the hard part: introducing a whisky subscription, explaining how the club worked, and reducing anxiety around recurring delivery. Visitors could learn the value proposition, but the buying action was tied to fixed CTA placements in the page content.

On a short landing page, that can be enough. On a long-scroll homepage, it creates a timing problem. A visitor may decide to subscribe after reading the "How it works" section, the delivery explanation, or the reassurance copy. If the CTA is no longer visible at that point, the page asks them to reverse direction, scroll back up, and find the button again.

The hypothesis was simple: keep the subscribe action available at the moment intent forms. Do not change the offer. Do not change the product. Remove the scroll-back requirement.

What We Tested on the Homepage

Page: Homepage
Location: Sticky CTA
Platform: Intelligems on a Convertibles A/B testing program
Audience: All visitors
Run dates: April 2-May 7, 2026
Timezone: Australia/Melbourne
Sample: 25,935 visitors, 327 orders, A$50,485 in test revenue

Control

The control homepage used standard in-page CTAs. Visitors saw the primary "Join the Experience" button near the offer explanation, then continued into the "How it works" education section. Once they scrolled past the button, the next action required either another in-page CTA later down the page or a scroll back up.

Variation: Sticky CTA

The variation added a sticky CTA bar to the bottom of the mobile viewport. The bar stayed available as visitors moved through the homepage and included compact reassurance copy:

• Free shipping
• Skip or cancel anytime
• Join now CTA

The point was not to make the page louder. The point was to keep the conversion action within thumb reach while the page did its education work.

The Result: More Orders Without Increasing AOV

Metric	Control	Sticky CTA	Lift
Visitors	11,808	14,127	-
Orders	134	193	+51 estimated orders/month
Conversion Rate	1.135%	1.366%	+20.4%
Revenue per Visitor	A$1.76	A$2.10	+19.57%
Profit per Visitor	A$0.63	A$0.74	+16.42%
Average Order Value	A$155.01	A$153.96	No meaningful change
Estimated Monthly Revenue	-	-	+A$7,632/month

Conversion rate was the cleanest read: +20.4%, with 95.1% probability to beat the control. Revenue per visitor moved almost exactly with conversion rate (+19.57%), while AOV stayed flat. That matters because it tells us the sticky CTA did not change order quality or basket size. It created more completed orders from the same type of shopper.

The RPV confidence interval was wider (+19.6%, -12% to +64%, 87.3% probability to beat control), which is normal on a lower-AOV subscription homepage where revenue variance is noisier than order count. The conversion-rate signal is the sturdier attribution: more people completed the subscription path.

Why the Sticky CTA Worked Here

1. The homepage had to educate before it could convert

A whisky subscription is not an impulse SKU. Visitors need to understand what arrives, how often it arrives, whether they have control, and what makes the club worth joining. A longer page was justified. The sticky CTA made that longer education path commercially useful instead of forcing a return trip to the top.

2. The CTA carried the two anxieties that block subscriptions

"Free shipping" and "Skip or cancel anytime" are not decorative microcopy. They address the two immediate objections subscription shoppers carry into the decision: unexpected cost and loss of control. Putting those next to the CTA made the action feel lower-risk at the exact moment the visitor could act.

3. The win came from conversion, not cart inflation

AOV moved from A$155.01 to A$153.96. That is effectively flat. The sticky CTA did not create a bigger order. It captured more of the visitors who had already been persuaded by the page and were ready to join.

4. The button followed intent instead of waiting for intent

Most homepage CTAs are placed where the brand wants the decision to happen. Sticky CTAs work when the actual decision happens later. In this test, the buying action stayed available while the visitor built enough confidence to use it.

When a Sticky CTA Is Worth Testing

This is not a universal "add sticky buttons everywhere" result. Sticky CTAs can hurt if they cover content, feel aggressive, or repeat a CTA that is already visible at the right time. They are worth testing when the page has real education work to do before conversion.

Good candidates:

• Subscription homepages with long "how it works" sections
• Premium products where visitors need reassurance before clicking
• Mobile-heavy pages where the original CTA disappears quickly
• Product or landing pages where shoppers decide after reading proof, ingredients, sizing, or delivery details
• Offers where reassurance copy near the CTA can reduce a specific anxiety

Bad candidates: short pages, pages with already-visible CTAs at every decision point, or sticky bars that block product information on mobile.

The Practical Rule

If your page needs to persuade before it asks for the click, the CTA should travel with the persuasion.

The winning variation did not invent a new offer. It did not discount the subscription. It did not rewrite the whole homepage. It made the next step available after the visitor had enough context to take it.

That is the difference between adding pressure and removing friction.

Homepage Sticky CTA Test Questions

Was this test statistically significant?

Yes on conversion rate. The sticky CTA variation lifted conversion rate +20.4% with 95.1% probability to beat the control. Revenue per visitor also increased +19.57%, with an estimated +A$7,632/month, but its probability to beat control was 87.3%, so conversion rate is the cleaner statistical read.

Why did revenue per visitor rise if AOV did not change?

Because more visitors converted. AOV was effectively flat (A$155.01 control vs A$153.96 variation), so the RPV lift came from the conversion-rate increase rather than bigger orders.

Should every Shopify subscription brand add a sticky CTA?

No. It should be tested when the page is long enough that visitors make the decision below the original CTA. If the CTA is already visible at the decision point, a sticky bar may add clutter instead of removing friction.

What should a sticky CTA include for a subscription brand?

The CTA itself plus the smallest reassurance copy that addresses the subscription anxiety. In this test, "Free Shipping" and "Skip or cancel anytime" were enough. The bar should reduce risk, not become a second hero section.

Where should the sticky CTA appear?

Usually after the visitor has passed the primary in-page CTA, not immediately on page load. The point is to preserve access to the action once the original button is gone, not to interrupt the first impression.
