Guide — Ecommerce CRO
The Ecommerce CRO Checklist
27 fixes, ranked by revenue impact
Most stores don't have a traffic problem — they have a conversion problem spread across a dozen small leaks. This is the checklist we run against every store we work on, in the order that moves revenue fastest. Work top to bottom: the sections are ranked by typical impact, and every item is something you can verify on your own store today.
01
Product pages
This is where the buying decision actually happens. A weak product page wastes every dollar spent getting someone to it.
- 01
Answer the three buying questions above the fold
What is it, why should I trust it, and what happens if it doesn't work for me. If a shopper has to scroll to find price, shipping, or returns, you're losing the impatient majority.
- 02
Write benefit-first product copy
Specs describe; benefits sell. Lead with the outcome the buyer wants, then support it with specifications for the detail-readers.
- 03
Show the product in context, not just on white
Studio shots build catalogs; in-use photos build desire. At minimum: one contextual hero image and one detail shot per product.
- 04
Put reviews where the decision is made
A star rating near the price outperforms a review section buried at the bottom. Pull the single best review up next to the buy box.
- 05
Make the primary CTA unmistakable
One visually dominant add-to-cart button. Every competing element near it — social icons, accordion links, upsell noise — pays rent in conversion rate.
- 06
State shipping cost and delivery time before checkout
Unexpected shipping cost is the #1 reported reason for cart abandonment. Surprise fees at checkout convert curiosity into resentment.
02
Cart & checkout
The highest-intent visitors you will ever have are in your checkout. Friction here is the most expensive friction in the business.
- 07
Remove forced account creation
Guest checkout first, account offer after purchase. Making a first-time buyer create an account trades revenue for a database row.
- 08
Cut form fields to the minimum
Every field is a tax on completion. Autofill-friendly inputs, address lookup, and no 'how did you hear about us' until the thank-you page.
- 09
Show a progress indicator and keep totals visible
Buyers tolerate steps they can see the end of. A visible order summary prevents the 'wait, how much?' back-button moment.
- 10
Offer the payment methods your market expects
Apple Pay and Shop Pay on mobile, PayPal for trust-cautious buyers, and local methods for international markets. Each missing option is a segment lost.
- 11
Recover abandonment within the first hour
Most recovered carts come from the first reminder. An email (or SMS, with consent) inside 60 minutes beats a discount three days later.
03
Speed & mobile
Most ecommerce traffic is mobile, and mobile buyers are the least patient. Speed is a conversion feature, not an engineering vanity metric.
- 12
Get Largest Contentful Paint under 2.5 seconds
Test your top 5 revenue pages on a real mid-range phone, not your laptop. Conversion drops measurably for every extra second.
- 13
Compress and lazy-load imagery
Serve modern formats (WebP/AVIF), size images to their containers, and lazy-load everything below the fold. Usually the single biggest speed win.
- 14
Audit your app and script stack quarterly
Every widget, popup, and tracking app adds weight. If you can't name what a script does for revenue, remove it.
- 15
Design thumb-first on mobile
CTA in the natural thumb zone, sticky add-to-cart on long product pages, and inputs that don't trigger zoom.
04
Trust & clarity
Shoppers who don't know you are looking for reasons to leave. Remove the doubts before they form.
- 16
Make returns policy a selling point, not fine print
'Free 30-day returns' near the buy button reduces perceived risk exactly where the risk is felt.
- 17
Show a human behind the brand
An about page with real people, a real story, and a real location outperforms a wall of stock-photo teamwork.
- 18
Use specific numbers over vague claims
'4.8 from 1,200 reviews' beats 'loved by thousands'. Specificity reads as honesty; superlatives read as marketing.
- 19
Answer objections in a visible FAQ
Sizing, shipping, materials, compatibility — the questions your support inbox gets are the questions silently killing conversions.
05
Offer & pricing
Sometimes the page is fine and the offer is the leak. No amount of design fixes an offer that doesn't feel like a clear yes.
- 20
Give bundles a reason to exist
Bundle around a job to be done ('everything for your first month'), not around inventory you want to move. Buyers can tell.
- 21
Anchor prices honestly
A compare-at price works when it's real. Fake anchoring gets noticed, screenshotted, and remembered.
- 22
Lift average order value at the point of momentum
Post-add-to-cart and post-purchase offers convert far better than product-page cross-sell noise — the buyer has already said yes once.
- 23
Test free-shipping thresholds against margin
'Free shipping over $75' moves order value up — if the threshold sits just above your current average order value, not double it.
06
Tracking & measurement
You can't optimize what you can't see. Broken measurement makes every other fix on this list a guess.
- 24
Verify your purchase event before anything else
Place a test order and confirm it lands in GA4 and your ad platforms exactly once, with the right value. Duplicate or missing purchase events silently corrupt every downstream decision.
- 25
Add server-side tracking for paid channels
Browser pixels lose a meaningful share of conversions to blockers and iOS privacy changes. Meta CAPI and server-side GA4 recover signal your ad algorithms need.
- 26
Track the funnel, not just the sale
View → add to cart → checkout → purchase, per device and per traffic source. The step with the biggest drop-off is your CRO roadmap, in order.
- 27
Change one meaningful thing at a time
Without disciplined testing, a redesign that 'felt better' can quietly cost 10% of revenue. Ship changes you can attribute, at a pace your traffic can measure.
