Sava Amsterdam

CRO testing roadmap

August
2026

Sava has a strong offer and deep trust signals, but shoppers meet them as separate messages across the journey. This roadmap makes the two-item value, community proof, durability, and risk reversal clearer at the moments where customers choose, add, and check out.

Testing roadmap

Slot 1A/B Test

PDP BOGO Value Builder

Product detail pages

The PDP shows $59.00, a $69.00 compare-at price, “SAVE $10.00,” and the BOGO offer as separate signals, while the cart reveals two items against a $138.00 value. The variation brings that complete two-item value into the buy box before the shopper adds to cart.

* The buy box states the complete two-item value before add to cart. Concept illustration only. Final design will differ.

Slot 2A/B Test

Community Proof Above Fold

Paid landing PDPs and Best Sellers collection

Offer-focused traffic sees “#iamsava” and “Over 180,000 members,” but the collected landing folds do not repeat that exact proof near the first action. The variation places the community size and hashtag beside the existing rating treatment before the CTA.

* Community proof from the traffic promise appears beside the existing rating before the first CTA. Concept illustration only. Final design will differ.

Slot 3A/B Test

Sticky Add to Cart

Product detail pages

The collected PDP shows the purchase action only in the first-fold buy box, while later sections contain UGC, press logos, related products, Trustpilot, and durability content. The variation keeps the Cross Chain name, $59.00 price, and add-to-cart action available after the shopper moves into proof and product content.

* The purchase action stays visible while shoppers review proof below the first fold. Concept illustration only. Final design will differ.

Slot 4A/B Test

Collection Hero Shop Path

Best Sellers collection

The collected Best Sellers hero presents BOGO, free shipping, lifetime guarantee, press logos, and the start of the product grid, but no visible primary button label. The variation adds one clear “Shop Best Sellers” action below the sale benefits.

SUMMER SALE✓ BUY 1 GET 1 FREE  ✓ FREE US SHIPPING✓ LIFETIME GUARANTEESHOP BEST SELLERSVOGUEVANITY FAIRGQTATLERBAZAAR SUMMER SALE✓ BUY 1 GET 1 FREE✓ FREE US SHIPPING✓ LIFETIME GUARANTEESHOP BEST SELLERSVOGUE  GQ  TATLER

* The sale hero gains one visible route into the existing product grid. Concept illustration only. Final design will differ.

Slot 5A/B Test

Collection Card BOGO Math

Collection and homepage product grids

Collected product cards show imagery, badges, ratings, names, compare-at prices, and red sale prices, but they frame the offer as a single-item discount. The variation adds “Buy 1, get 1 free” and “2 for $59.00” directly under the sale price.

Slot 6A/B Test

Cart Risk Reversal Stack

Cart drawer

The cart drawer confirms the free item, free shipping, and Trustpilot, but the collected state does not show the lifetime guarantee or 60-day returns. The variation repeats all three risk-reversal promises directly below “Checkout Securely.”

* The checkout area repeats free shipping, lifetime guarantee, and 60-day returns. Concept illustration only. Final design will differ.

Slot 7A/B Test

PDP Durability Proof

Product detail pages

Live PDP metadata identifies waterproof 316L stainless steel, while the purchase fold places the silver and gold swatches apart from the fuller durability story below. The variation puts “Waterproof 316L steel. Made for sea, pool, and shower.” directly under material selection.

CROSS CHAIN | SILVER$59.00MATERIAL · PREMIUM STAINLESS STEELWATERPROOF 316L STEELMade for sea, pool, and shower. CROSS CHAIN | SILVER$59.00MATERIAL · PREMIUM STAINLESS STEELWATERPROOF 316L STEELMade for sea, pool, and shower.

* Durability proof sits with material selection instead of relying on lower-page content. Concept illustration only. Final design will differ.

Slot 8A/B Test

BOGO Second-Item Module

Product detail pages

The PDP moves from “As Seen on You” and press logos into a generic “You May Also Like” grid, while the cart confirms the second item is free. The variation adds a “Choose your free second item” module before the existing related-product grid using familiar Sava product cards.

VOGUE  VANITY FAIR  GQ  TATLER  BAZAARCHOOSE YOUR FREE SECOND ITEMMix and match during the Buy 1 Get 1 Free sale.CROSS CHAIN$59.00CHOOSE FREECROSS BRACELET$59.00CHOOSE FREE CHOOSE YOUR FREESECOND ITEMMix and match during the Buy 1 Get 1 Free sale.CROSS CHAIN$59.00CHOOSE FREE ITEMCROSS BRACELET$59.00CHOOSE FREE ITEM

Cross-source synthesis

Biggest Killers of Conversion Rate

  • The BOGO value appears in fragments

    Ads, homepage, PDP, collection, and cart repeat the offer differently. The clearest two-item economics appear only after add to cart.

  • Trust proof is vertically scattered

    Community size, ratings, press logos, Trustpilot, warranty, shipping, and returns exist, but high-value proof is split across components and page depths.

  • Choice support trails the catalog

    Cards show ratings and sale prices, but the collected grids do not show BOGO math, visible filters, or a second-item selection path.

  • Dispatch promises meet inconsistent delivery

    The PDP shows same-day dispatch. Collected reviews include next-day shipping taking four days to ship, an order purchased July 22 still unsent July 31, and one delivery taking three weeks, while other reviewers report fast delivery.

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.
