August Concepts

Four data-backed concepts for the August slot, each targeting a high-impact surface. DefenderShield runs one test a month, so pick one to run.

Concept 01 · Cart

Show the free-shipping finish line

Why we're testing

Free shipping starts at $150, but the cart never mentions it, even when an order already qualifies, and the typical order stops just short. Show the finish line at the top of the cart, and give shoppers something to add to reach it.

What the variant changes
  • Threshold visible up top. A live "you're $X away from free shipping" bar at the top of the cart, counting up to the $150 line.
  • A cross-sell section. A short "complete your setup" row of complementary products the shopper can add toward the line.
Your cart × You're $10 away from FREE shipping EMF Protection Blanket $139.99 COMPLETE YOUR SETUP Sleep Mask $24.99 Add Estimated total $139.99 Free shipping on orders over $150. Checkout

Concept illustration only. Final design will differ. Free shipping at $150; the cross-sell products shown are placeholders to confirm.

Evidence
The typical order stops short of the line. Average order value is about $143 and the median about $100, both under the $150 free-shipping threshold, so most baskets never reach it. Shopify orders · 90 days
Shipping is silent in the cart. The cart says nothing about shipping, even when the order already qualifies for free shipping, so the incentive that exists is invisible at the moment it would work. Site audit · Aug 2026
The rules trip people up. Survey buyers report losing free shipping when a discount code is applied, and similar shipping confusion at checkout, so a clear, stated threshold reduces friction as well as adds a nudge. Post-purchase survey · 4,820 responses

Concept 02 · Cart

Make Checkout+ a choice, not a default

Why we're testing

Today Checkout+ is pre-checked and the cart's primary button bakes it into the price, and customers resent it. Cutting the drop-off it causes at cart and checkout should lift both conversion rate and revenue per visitor.

What the variant changes
  • Off by default, one clear button. Checkout+ starts unchecked and the true subtotal shows in a single "Checkout" button, with no add-on baked into the price.
  • A tidy toggle. Present Checkout+ as a small toggle with an info circle for the details, placed by the checkout button, so the offer stays available without cluttering the cart.
Your cart × Air Tube Earbuds Style: USB-C $89.99 Estimated total $89.99 Add Checkout+ ($4.15) i Off by default. Checkout Today: pre-checked add-on; main button reads "Checkout+ | $94.14."

Concept illustration only. Final design will differ. A compact opt-in toggle with an info circle replaces today's pre-checked add-on and dual-button cart.

Evidence
Customers name it as the problem. Survey buyers call it "a gimmick" that "makes zero sense." Reviewers report add-ons "added automatically" and being "charged for delivery insurance by force." Post-purchase survey · 4,820 responses; Trustpilot · 12 months
Even buyers don't realize it's optional. Survey and review comments show customers who completed a purchase did not know the add-on could be removed, so many who drop off at cart or checkout likely never notice the faded "continue without" option.

Concept 03 · Product page

Keep the buy button in reach

Why we're testing

The buy box sits high on a long product page, and there are no calls to action below it at all. Shoppers who scroll down into the specs, reviews, and FAQ have no way to buy without scrolling back up. A persistent sticky bar keeps the buy action in reach the whole way down, on desktop and mobile.

What the variant changes
  • Sticky add-to-cart bar. Once the buy box scrolls out of view, a slim bar with the price, the connector choice, and Add to cart pins to the edge of the screen on product pages, on both desktop and mobile.
1 / 11 EMF Radiation-Free Earbuds ★★★★½ 886 reviews $89.99 Below the buy box: specs, FAQ, and reviews run on for ~18,000 px, with no CTA anywhere. Air Tube Earbuds $89.99 · USB-C Add to cart

Concept illustration only. Final design will differ. Shown on mobile; the same sticky bar applies on desktop. Bar contents to confirm.

Evidence
There are no calls to action below the buy box. Once a shopper scrolls past Add to cart into the specs, FAQ, and reviews, nothing invites them back to purchase. Site audit · Aug 2026
Only about a third of mobile visitors reach it. Roughly 33% scroll far enough to see the main Add to cart, so for most, the buy action never appears on screen. Microsoft Clarity · 30 days to Aug 8
They keep reading past the buy box. On mobile, scroll depth tapers off gradually rather than falling off a cliff at the buy box, so a meaningful share read down into the specs, FAQ, and reviews, still with no way to act. Microsoft Clarity · 30 days to Aug 8

Concept 04 · Homepage

A sharper hero with one clear path

Why we're testing

On the homepage, almost no one clicks the secondary "Learn How It Works" CTA or the hero "Read more." Nearly everyone either hits the primary CTA or opens the menu to find a product themselves. Give the hero one clear path, more proof up top, and a tidier value block, so more visitors move in the same direction.

What the variant changes
  • A Trustpilot line above the headline. Lead with proof, for example "Rated 4.4/5 on Trustpilot by 197 customers," so the rating is the first thing seen.
  • One clear CTA. Keep a single primary action and drop the secondary "Learn How It Works" that draws almost no clicks.
  • A tidy value block. Consolidate the trust badges into one coherent USP block under the CTA, dropping the ones that don't matter at this stage, such as Secure Checkout.
★ 4.4/5 on Trustpilot · 197 customers The trusted authority in EMF & 5G shielding Protection without sacrifice, for every device. Get Protected → One clear CTA. Secondary link removed. ONE CONSOLIDATED VALUE BLOCK FCC-Certified · Free shipping $150+ · 30-day returns Today: two CTAs (the secondary is rarely clicked) and a trust strip that wraps onto two lines.

Concept illustration only. Final design will differ. Trustpilot rating, headline, and the exact USP set are placeholders to confirm.

Evidence
The secondary paths go almost unused. Clarity click data shows the "Learn How It Works" CTA and the hero "Read more" draw almost no clicks, while nearly all hero interaction is the primary CTA or the menu. Microsoft Clarity · click & interaction data
It is the most-seen surface on the site. The homepage is the number-one landing page at 10,487 sessions, so a clearer single-path hero compounds across more visitors than any other page. Microsoft Clarity · 30 days to Aug 8
Proof is the lever here. Winning ads lean on scale and authority (300,000+ customers, recommended by doctors), so leading the hero with a proof line plays to what already converts. Meta ad creatives

The single highest-leverage surface to work next is the landing page. The move depends on how the current DSHIELD-03 offer landing page performs on paid traffic.

Future High Impact Area

The landing page, hardened or reangled

Why it matters

The offer landing page is where paid traffic converts or leaks. How the DSHIELD-03 offer performs on paid traffic points to the next move. If it wins, the work is to harden it and scale spend behind it. If it underperforms, the work is to try a different angle.

Two directions, depending on how DSHIELD-03 performs
  • Harden the winner. If the value stack performs and we can scale paid behind it, tighten the offer: the hero product, the free extras, and an ad-to-page promise that matches the click.
  • Try a different angle. If it underperforms, an alternative to test against it: a different offer, a new hook, or a different page format.

[ WHAT OUR CLIENTS SAY ]

At Performance Golf we have worked with dozens of agencies. We are a nine figure brand and growing and our agency experiences, let's just say they haven't been that great, but Convertibles has completely flipped that on its head.

We needed a very high conversion landing page for mostly cold, some semi warm traffic coming primarily off of social. I had heard about Convertibles, decided to give them a try. They knocked it out of the park. There is so much strategy they pour into every step of the process. I learned a ton as we went. They made it fun, easy and the site is performing way better than I was expecting or hoping. So thank you guys. Can't wait for the next one.
