Your Site Redesign Will Break the Member Experience and Nobody Is Planning for It

Redesigns happen on a cycle. A Shopify Plus brand that launched its current theme two years ago is probably planning a new one. The brief covers the homepage, the product pages, the navigation, the checkout, and the brand's visual refresh. It does not cover the member account page, because the member account page is usually handled by whoever maintains the membership platform, not by the agency or designer running the redesign.

The result is a launch day where the storefront looks polished and the member experience is broken in three places: nobody caught in QA because nobody on the QA team is a member. The credit display is missing from the account page because the new template does not include the field the membership platform was outputting to. The join flow has a new design that looks better but converts 15 points lower because the designer changed the perk order based on aesthetic judgment rather than the A/B test data the previous version had accumulated. The welcome email link goes to a page that no longer exists under the new URL structure.

These are not hypothetical scenarios. They are the most common support ticket cluster that follows any Shopify Plus site redesign that did not include the membership experience in the brief.

The Membership Experience Is Spread Across More Pages Than Most Redesigns Account For

A membership program touches more pages on a Shopify Plus store than most redesign briefs acknowledge. The join page or modal. The member account page and credit display. The checkout, where the member discount or credit applies and where member pricing should be visible. The product pages, where member pricing may be surfaced. The post-purchase email, which should reference the member's credit status. The restock notification, which should route to a member-priority channel. Every one of these is affected by a site redesign, and most redesign briefs mention none of them.

Baymard Institute's checkout usability research consistently finds that any change to a checkout flow requires fresh testing because user behavior shifts with the interface. A redesigned checkout that moves the member credit display to a different position or removes it entirely for a cleaner aesthetic has just changed the redemption behavior of every member who checks out from that day forward. That change is unintentional and unmeasured unless someone includes the member checkout experience in the redesign QA process.

The Join Flow Conversion Rate Is the Most Fragile Asset in the Redesign

The membership join flow is usually the result of months of iteration. A brand that has been running its membership for eighteen months has likely tested headline copy, perk order, fee framing, and CTA placement at least once. That accumulated learning lives in the current design, not in any document the redesign team inherits.

When a designer rebuilds the join page based on the brand's new visual direction, they are making aesthetic decisions that overwrite conversion decisions nobody told them existed. The perk list order that was tested and optimized gets replaced by the order that looks most visually balanced. The fee framing that is converted best gets replaced by the one that fits the new grid layout.

Research on landing page conversion from ConvertCart found that the elements with the highest tested impact on conversion, headline framing, benefit hierarchy, and CTA placement, are also the elements most likely to be changed in a redesign based on aesthetic preference. Without a documented record of what was tested and what performed, the redesign erases the testing history.

The Membership Brief Should Be a Separate Document

The fix is straightforward: before the redesign brief goes to the agency or designer, produce a separate membership experience brief that documents every page the membership touches, what the current conversion rate or redemption rate is for each, and what constraints should be preserved through the redesign. That document does not prevent creative decisions. It prevents decisions that break things nobody knew were working.

Subscribfy's own merchant data shows conversion rates like a 45% checkout opt-in rate at Dossier and 49% at Tres Colori. Those rates exist in specific implementations that accumulated through testing and iteration. A redesign that replaces those implementations without documentation starts the optimization process from zero.

If your next site redesign brief does not include a membership experience section, your redesign agency is making membership decisions they do not know they are making.

Subscribfy helps Shopify Plus brands document and protect their membership experience through site redesigns so the conversion and redemption rates built through iteration survive the process. See how at subscribfy.ai.
