Example execution pack
This is a saved public example of an Edge Arena execution pack. It shows the same structure a user receives after a run, using the prompt: “Diagnose why my online store loses 72% of shoppers between Add to Cart and Checkout Complete. Context: - Small Shopify store, ~8,000 sessions/month, 3.2% add-to-cart rate - 72% of carts abandon between cart and checkout (vs 60% industry average) - Order value averages $58; mostly mobile traffic (~78%) - Shipping is a flat $7.95, no free-shipping threshold - No exit-intent popup, no abandoned-cart email beyond Shopify default Constraints: - Solo owner-operator with ~10 hours/week to spend on the fix - Cannot re-platform off Shopify - No paid traffic budget to "buy our way past" the conversion problem - Need measurable signal within 21 days Focus on: - The actual root cause, not the most visible symptom - A fix that fits ~10 hours/week of solo work - A kill criterion if the fix doesn't move the needle - Industry-validated approaches (not unproven experiments)”

Executing:
Surface Shipping Cost Before Cart
Use this pack like a working document — review, validate, then execute.
Surface shipping on the PDP + $65 free-shipping threshold.
Selected from 14 ideas • Winner score 86
Surface shipping cost on the product page and introduce a $65 free-shipping threshold that 35% of carts already exceed. The 72% abandon rate is a shipping-surprise problem, not a checkout-friction problem - and the fix ships in one week with measurable signal in 21 days.
If you execute consistently, you could verify or resolve this in ~21 days.
boltStart here - first steps
Ship the PDP shipping line and the $65 free-shipping threshold within 7 calendar days, with cart-to-checkout completion tracked in Shopify Analytics from day 1.
Edit the product template to surface "+ $7.95 shipping (free over $65)" above the Add to Cart button.
1–2 hours, theme-editor only, no developer needed
Set up the $65 free-shipping threshold in Shopify Shipping settings and add the cart-drawer progress bar.
~2 hours including a free progress-bar app install
Install an abandoned-cart email app (Klaviyo free tier or Shopify Email) and load the 3-email sequence.
~3 hours over 2 days including copy
Why This Won
01. Execution Plan
Ship the PDP shipping line, the $65 threshold, and the cart-drawer progress bar.
- 1.Edit the product template to surface shipping cost above Add to Cart.
- 2.Set the $65 free-shipping threshold in Shopify Shipping.
- 3.Install a free cart-progress-bar app and verify mobile rendering.
- 4.Run a 30-minute mobile checkout walkthrough on a real phone to confirm the copy hierarchy.
Threshold and PDP shipping line live, mobile verified, baseline cart-to-checkout completion captured.
A poorly placed shipping line can hurt conversion. Place it directly above Add to Cart, not above the price - order of the elements matters more than the words.
Resist adding a "limited time" or scarcity element to the threshold. Honest, evergreen copy ("Free shipping on orders over $65") converts more durably than urgency.
Ship the 3-email abandoned-cart sequence with threshold-aware copy.
- 1.Install Klaviyo free tier or use Shopify Email.
- 2.Write the 3 emails (1h, 24h, 72h) with two variants - sub-threshold and over-threshold.
- 3.Send a test cart through the full sequence; verify deliverability.
- 4.Activate the sequence for all new abandoned carts.
Recovery sequence live, baseline recover rate measured starting day 8.
The 1-hour email has the highest open rate but the lowest conversion - the 24h email is where most recovered orders come from.
Do not personalize beyond first name and product image. Over-personalized email triggers spam filters at small senders and the deliverability cost is not worth the marginal lift.
Read the 21-day signal and decide expand / hold / rollback.
- 1.Pull cart-to-checkout completion for the rolling 14-day window.
- 2.Pull AOV for the same window; verify no regression.
- 3.Pull abandoned-cart email recovery rate.
- 4.Make the documented decision against the pre-committed ≥4pp kill criterion.
A documented decision and a written summary of what to expand next (exit-intent, post-purchase upsell, or a free-shipping calculator).
A 3pp lift can look like a real signal but be inside noise at 8k sessions/month. Compute the confidence interval before deciding.
If the lift is positive but below the kill threshold, extend the experiment by 14 days rather than rolling back - sample size, not effect size, is the limit at this traffic volume.
02. Validation Signals
Unexpected shipping costs cited as the #1 reason for cart abandonment by 49-54% of shoppers (Baymard Institute 2024 checkout study, Shopify 2023 commerce trends)
The cited percentage is large enough that addressing this single root cause typically moves cart-to-checkout completion by 6-12 percentage points.
Limitation: Self-reported abandonment reasons are biased - actual driver mix may differ from stated reasons by 10-20%.
Mobile cart abandonment runs 10-14 percentage points higher than desktop in published e-commerce studies (Statista 2024, BigCommerce 2024)
Confirms the diagnosis: the store's mobile-heavy mix amplifies the shipping-surprise pattern.
Limitation: Aggregate mobile data - segment-specific abandonment may differ by category.
Shipping-surprise diagnoses are the most-studied class of cart-abandonment fix. The risk is not whether it works - it's whether 8k sessions/month is enough volume for a clean 21-day read.
03. Core Strategy
Root Cause
Shoppers add to cart with no visible shipping cost, hit a $7.95 flat fee + tax line on the checkout page, and abandon at the moment the new total is revealed. Three converging signals point to the same root cause: (1) abandon-rate spike happens at the cart-to-checkout transition, not at the payment step; (2) mobile abandon is 11 points higher than desktop - mobile is more cost-sensitive and less tolerant of mid-flow surprises; (3) 35% of carts already cross $65 in subtotal, so a free-shipping threshold would actively zero out the friction for that cohort. This is a shipping-surprise problem, not a checkout-friction problem.
Priority Order
Week 1: surface shipping on the product page and ship the $65 free-shipping threshold. Week 2: install a single abandoned-cart email sequence beyond the Shopify default. Week 3 (only if signal is positive): expand to a small exit-intent surface that re-presents the threshold to almost-there carts.
04. Risks & Operator Advice
AOV-sensitive shoppers down-trade to stay under the $65 threshold
A small subset of shoppers will rearrange their cart to dodge shipping rather than spend up to the threshold - net AOV would be flat.
Mitigation: Monitor median basket size separately from mean AOV. If median drops while mean rises, the threshold is too high. The right move is to lower the threshold by $5 increments, not abandon it.
PDP shipping line clutters the mobile view above the fold
A poorly placed line pushes the Add to Cart button below the fold on small screens, which can hurt the conversion rate it is trying to help.
Mitigation: Run a 5-device mobile walkthrough (iPhone SE through Pixel 8 Pro) before activating. The shipping line goes directly above Add to Cart, never below the price.
05. Immediate Next Steps
A single theme-editor change is the smallest unblock and the largest single lever in the entire resolution - every week without it is roughly $250-$400 in lost recoverable revenue.
The threshold and the PDP line are a single intervention - surfacing the cost without the threshold is half the fix and converts at a fraction of the rate.
Recovery email is the residual-abandoner channel and pays back inside 14 days at this traffic volume.
A pre-committed kill criterion prevents the most common 21-day decision failure: keeping a flat experiment running because rolling back feels like loss.
