Audit

Eleven sections. Every touchpoint a visitor moves through, from the homepage to checkout. This is the same checklist we run before we diagnose a store. It shows you what to look for. It cannot tell you which leak is costing you the most, that needs your data. Proof, not opinions.

Stage 1, First Impression
01

Homepage

Most brands treat the homepage like a brochure. It isn't. It converts the brand, not a specific product. A visitor who lands here is undecided. Your job is to end that. When we audit a store, the homepage is where the most expensive assumptions hide, and the change with the biggest revenue impact is rarely the one you would expect.

Above the Fold

The first three seconds decide whether a visitor stays. Three questions that must be answered before any scroll:

The hero image test
Cover the headline. Can a visitor tell what you sell from the image alone? If the answer is no, the image is wrong. Abstract photography, lifestyle scenes without the product, or stock images are all failure modes here.

LCP, Largest Contentful Paint

The hero image is almost always the LCP element, the largest asset the browser has to load before the page feels usable. A hero image above 200KB adds measurable bounce on mobile. Compress it. Test the load speed on a mid-range phone before calling the hero done.

Social Proof, Before the Scroll

Not full reviews. Aggregate signals. The goal is to create immediate credibility before the visitor has formed an opinion.

Featured Collections

The homepage is where you direct traffic, not list inventory. Three rules:

Email Capture

Bad offer

"Sign up for updates." Nobody wants updates. This converts at under 1% and makes your list worthless.

Good offer

A discount, exclusive product access, a quiz result, or content your customer would actually pay for. Something specific, something valuable.

Below the Fold, What Belongs

Below the Fold, What Doesn't Belong

Mobile Homepage

What good looks like
A visitor knows what you sell and who it's for before they scroll. One CTA is dominant. The hero image loads fast. Social proof appears above the fold. Curated collections make the catalog feel manageable. Below the fold: bestsellers, a brief story, proof, and a quiz path, in that order. Nothing that could be cut without losing a sale.
02

Navigation

The first decision, and most brands get it wrong by default.

Drawer or Mega Menu

Universal drawer

Right for brands that can frame their top-level options leanly. If you can get to ~10 clear entry points, each with sub-items, use a drawer everywhere.

Mega menu on desktop

Right for brands with so many categories that a drawer can't contain them cleanly. Drawer on mobile still.

The question isn't how many products you have. It's whether you can make the navigation feel like ~10 choices. If you can, drawer. If you can't, mega menu on desktop.

Image-First

Nobody reads navigation menus. They scan. Text-only navigation requires effort. Image-first navigation is instant, visitors see where they're going before they've finished thinking about it.

Use text as little as possible. Use images as much as possible.

High-Value Destinations

Are you sending visitors to the pages that match how customers actually think about shopping? For a jewelry brand, that's not just category links. It's:

Cover every shopping scenario. If a visitor has a use case and can't find a path to it in the navigation, they're gone.

Lean Top-Level Structure

Group everything into a small number of clear entry points, occasion, category, gender, and let each one expand into its sub-items. The goal is to make a large catalog feel manageable from the first glance.

Navigation Tabs

Instead of a standard accordion (click a category → items drop down below it), consider horizontal tabs at the top of the drawer. Each tab loads its own sub-navigation panel when tapped. Cleaner, faster, more visual, especially on mobile where vertical space is limited.

Highlight Cards

At the top of the navigation, a small grid or carousel of standout collections or featured items. Not every option. The ones you most want visitors to see first.

Quiz

A quiz should be visible inside the navigation. Not buried. Visitors who can't find what they want through browsing need a different path, the quiz is that path. Treat it as a top-level navigation destination, not a footnote.

Support Submenu

At the bottom of the drawer, faded, smaller, clearly secondary, a set of non-selling pages that help customers buy better:

Search

Search belongs inside the navigation drawer, not just in the header.

What good looks like
Open the navigation and know immediately where to go. Image-first. Lean top-level options that cover every shopping scenario. A support layer at the bottom for customers who need more before they buy. Search that works as you type and never hits a dead end.
Stage 2, Discovery
03

Site Search

Most brands treat search as an afterthought. It's a checkout lane. A visitor using search has already decided they want something specific, they just need you to get out of the way and show it to them.

The stat that matters
Search users convert 5–10× more than non-search users. If your search experience is broken, slow, or buried, you're leaving your highest-intent visitors to figure it out themselves.

What to Check First

Predictive Search

Results should appear as the visitor types, not after they hit submit.

Dead Results

If a search returns nothing, "No results found" is the wrong response.

Show instead
A set of high-selling category links and a selection of best-selling product cards. Prioritize categories. At this stage the visitor is still in discovery mode, sending them to a category gives them a path.

Search Placement

Surface it wherever a visitor might need it:

What good looks like
A visitor types two characters and sees full product cards, collection cards, and page results populate instantly. Autocomplete finishes their thought. If what they're looking for doesn't exist, they're redirected to the closest high-value alternative, not a dead end.
04

Collection Page

Most brands treat the collection page like a holding area. It's not. It's the primary discovery engine, where a visitor either finds what they came for or leaves.

Start Here: Framing

Before anything else, count the products.

<10
Under 10 products
Don't use a collection grid. Use a featured card layout. Think Crumbl Cookies homepage. Standout cards, not rows of thumbnails.
~
Under 10 with lots of variants
Split variants into individual listings. Each color, each flavor, each option gets its own card. The grid should feel full.
30+
30+ products
Standard collection grid is correct. Everything below is for this context.

Layout & Discovery

Filters & Sorting

Product Cards

Quick Add

Bad

No quick add at all.

Good

Quick add button that adds directly to cart.

Great
Two-step quick add. Clicking "Add" opens a drawer, not the cart, a focused drawer.

The drawer should contain: media gallery with image scroll, color selector (images update as you switch), size selector, 2–3 line product description, Add to Cart button, View Full Product link.

For fashion: on hover (desktop) or on quick-add tap (mobile), show a size overlay directly on the product card first. When they select a size, then open the drawer with that size pre-selected.

Image Interaction

Can visitors scroll through product images from the collection page without going to the PDP? On hover, carousel arrows should appear, or a thin progress bar at the bottom of the image that fills as you scroll through shots.

UX & Navigation

Below the Grid

Collection Banner

Inventory

Are out-of-stock products hidden? In most cases, yes. Exception: scarcity-based brands, where showing sold-out previous collections reinforces demand. If you're running paid traffic to a collection, every product in it should be in stock.

What good looks like
Products sorted by revenue performance, not upload date. Filtering brings the count down fast. Quick add reduces friction without polluting the cart. The best products stand out visually. Image quality is high, shot lists are complete. Scroll position is preserved. Discovery options, search, subcollections, quiz, are surfaced at the right moments. The design feels premium, not assembled.
05

Collection Sort Order

Shopify's default best-seller sort ranks by units sold, all time. That's the wrong metric. A $12 accessory that moved 400 units is not your best seller. Sort by revenue.

T1
Sort by Revenue
Change one thing: switch Shopify's best-seller sort from units sold to net revenue generated. This alone will immediately surface the products actually driving your business.
T2
Revenue + Time Decay
All-time revenue rewards old products that had a good run years ago. Add a rolling window, last 30, 60, or 90 days, and weight recency into the rank. High revenue, recent → top. High revenue, old → middle. Low revenue, old → bottom.
T3
Full Scoring Formula
Build a score for each product and sort by that score. Each variable is normalized to a 0–100 scale before weighting.
Score = (Revenue × 0.40) + (Margin × 0.25) + (Sell-Through Rate × 0.20) + (Recency × 0.15)
VariableDefinitionWeight
RevenueNet revenue generated in the last 90 days40%
MarginProfit margin pulled from Shopify's cost-per-item input25%
Sell-Through RateUnits sold ÷ units available × 10020%
RecencyNewer products receive a score boost; old slow-movers are penalized15%

These weights are a starting point, not a fixed rule. Adjust based on what your business actually needs to prioritize.

Tier 4, Niche-Specific Layering

The formula above applies to any store. What sits on top of it is specific to your customer. For fashion, add seasonality. Certain products sell heavier in summer, others in winter. Layer that in as a conditional, you're not replacing the formula, you're adding conditions on top of it.

If season = summer → apply seasonal boost to summer items
If season = winter → apply seasonal boost to winter items
What good looks like
A collection sorted by revenue, at minimum. Ideally by a weighted score that factors in margin, sell-through, and recency. Products that drive the most value sit at the top. Seasonal and niche-specific conditions are layered on for brands that need it.
Stage 3, Evaluation
06

Product Page

Ninety percent of visitors never scroll past the product images. If the image section fails, nothing else on the page matters. Start there. Fix everything else second.

Product Images

The first thing I audit, before anything else on the page.

Overlaying the Media

What sits on top of the main image before the visitor scrolls:

Above the Fold, Before Scrolling

Variant Selection

Don't auto-select size. Prompt the visitor to choose. This forces engagement and reduces the wrong-size return rate.

Exception
Don't do this with color. Color is tied to image rendering, auto-selecting a default color and loading its images is correct. Size is not tied to imagery in most cases, so leaving it unselected is the right call.

Page Content, Modals Over Inline Text

Do not lay out walls of text on the product page. Put everything behind a trigger.

Upsells and Bundles

Below the Fold

UGC

Inside the Gallery

UGC video alongside product shots, treated as a first-class media asset.

Floating Bottom-Right

As the visitor scrolls, a UGC video specific to that product appears in the corner. Starts muted. Plays on scroll. Visitor can unmute. Links to the product.

Prelanders

Optional. The purpose is education. When it's done right, it lifts revenue. When it's done wrong, it adds friction with no return. For most brands, the product page itself should carry the education load first. Prelanders come after everything else is optimized.

What good looks like
The media section is complete, fast, and consistent. Every niche-required shot exists. The visitor can zoom, scroll through the gallery, and change color, all without leaving the image area. The add to cart is always visible. Variant selection is intentional. Everything that could be a block of text is behind a trigger. Upsells are conditional. Reviews are prominent. The page educates without overwhelming.
07

Mobile UX

Most mobile audits are done on a flagship iPhone with a fast connection. That's not your customer.

Test on the right device
Test on an iPhone 12 or a mid-range Android. Unless you have hard data showing your audience is exclusively on premium devices, which almost no brand does, optimize for the average phone.

Image Sizing

Four aspect ratios. Two that matter.

RatioDimensionsUse
4:51080 × 1350pxDefault for all product images
1:11080 × 1080pxSecondary option
9:161080 × 1920pxUGC video and full-frame content only

Do not use 4K images. Compress everything to between 400KB and 3MB. Shopify's upload limit is 20MB, that's not a target, it's a ceiling. Good lighting and a good shot at 1080px will outperform a poorly lit 4K image every time.

If images load slowly, customers don't stick around long enough to see them. Image quality means nothing if it never loads.

Speed

Two separate problems your customer experiences as one: site load time and content load time.

Run your domain through PageSpeed Insights to see exactly what's slowing you down.

Tap Targets & Basic Functionality

Before anything else, do things work when you tap them?

This sounds obvious. Test it anyway. Broken tap targets on mid-range phones are more common than they should be, even on 7-figure stores.

Navigation

Dead search results
If a search returns nothing, never show an empty state. Show popular categories. Give them somewhere to go.

Collection Page on Mobile

Two columns max. That's it.

Product Images

Content Digestibility

Text Size

Product names and body copy should be readable without zooming. Small text on mobile is a conversion killer. If you're squinting at it during the audit, customers are leaving because of it.

Header

General

What good looks like
The site loads fast on a 3-year-old phone. Images are compressed, correctly sized, and load just before they're needed. Taps register on first touch. Navigation is visual, covers every use case, has search built in. Collection pages use two columns. Images zoom properly. Everything that could be a paragraph is a table or an accordion. The header stays out of the way. Scrolling is smooth from top to bottom.
Stage 4, Conversion
08

Trust Signals

Do not fake anything. Not reviews. Not scarcity. Not social proof numbers. Fake trust is worse than no trust.

Why it matters
Ninety percent of customers research your brand externally before they buy, Reddit, Google, TikTok. If they find one thing that contradicts what you're showing on your site, you've lost them permanently. A thousand fake reviews next to a Reddit thread full of complaints will convert worse than zero reviews with nothing negative out there.

The Only Signal That Consistently Moves the Needle

Video. Not influencer content. Customer content. Real people, real results, real language.

Four Types of Reviews, Ranked by Value

1
Video
Highest trust, highest conversion impact.
2
Image + text
Strong, especially with detailed written reviews.
3
Audio
Rarely seen. Worth testing, likely outperforms text alone.
4
Text only
Baseline, still worth having.

Where to Put Video Reviews

Make them conditional. A UGC element that appears everywhere unconditionally becomes noise. Triggered at the right moment, it converts.

What Doesn't Work

The generic trust icons, "Trusted by 10,000 customers," "Secure checkout," gold shield badges, rarely create measurable lift. They add visual clutter and signal that you're trying to manufacture credibility rather than demonstrate it.

Niche-Specific Trust Signals

CategoryTrust signals that actually work
SupplementsHSA/FSA eligibility, certifications, licenses, real doctor endorsements with credentials
FashionA sizing confidence widget showing what customers say about fit (runs small, true to size, runs large). Removes the single biggest hesitation in apparel.
High-ticket / MedicalFinancing options visible on the product page signal that the purchase is manageable

The Core Philosophy

The more you educate a customer about why a product is right for them, the use case, the benefit, what it feels like, what it does, the more they trust it. Education is trust. A well-placed UGC video of a real customer explaining why they love the product does more than any badge or icon ever will.

What good looks like
Real reviews, video first, image second, text supporting. UGC placed at the right moments across the site, not plastered everywhere. Niche-specific trust elements that address the actual hesitation your customer has. Nothing fake. Nothing generic.
09

Cart

Cart is where purchase intent crystallizes. Most stores treat it as a holding area. It isn't. It's the last structured opportunity to reinforce the purchase decision before checkout.

Cart Drawer vs. Cart Page

Cart Drawer

Right for most stores. Opens without leaving the current page, visitor can keep browsing. Faster, less disruptive, works well for orders with 1–3 items.

Cart Page

Right when order complexity is high, bundles, subscriptions, multi-SKU orders where the visitor needs to review everything at once before committing.

Never use both. Pick one and optimize it. A drawer that redirects to a cart page on checkout is a friction point, not a feature.

Cart Item Display

What must be visible without scrolling when the cart drawer is open:

Free Shipping Progress Bar

Upsells in Cart

One rule
Maximum two upsell products in the cart. More than that and completion rate drops. One well-chosen product, relevant to what's already in the cart, outperforms a grid of bestsellers every time.

Checkout CTA

Trust at Point of Purchase

Directly above or below the checkout CTA, one line of copy and one row of icons. No more.

Edge Cases

What good looks like
The cart opens without leaving the page. Free shipping progress is visible immediately. The visitor can see exactly what they're buying, product, variant, quantity, price, without scrolling. One well-placed upsell. The checkout CTA is always visible and unmissable. One line of trust copy, one row of payment icons. Nothing between the decision and the click.
10

Checkout

This is where the money is either collected or lost, and it's the stage most audits skip. The cart got them to the door. Checkout is the door. When we audit a store, more abandoned revenue hides here than anywhere else on the site.

Express Wallets, Above the Fold

Shop Pay, Apple Pay, Google Pay, and PayPal remove the single biggest checkout tax: typing. Returning shoppers convert far faster when they can pay in one tap. When we audit a store, express wallets are either buried below the form or missing entirely. Surface them at the top of checkout, not underneath a full address form.

What we find
Express wallets present but pushed below the fold, so the shopper starts typing before they ever see the one-tap option. The fastest path to purchase should be the first thing they see.

Guest Checkout

Forcing account creation before purchase is one of the oldest and most expensive mistakes in ecommerce. A visitor ready to pay does not want a password. Guest checkout must be the default path, with an optional "save your details" nudge after the sale, never before it.

Shipping Cost Transparency

Unexpected shipping cost at the final step is the number one documented reason for cart abandonment. If shipping is a surprise on the payment screen, you have trained the visitor to distrust every number before it. Show the shipping cost, or the threshold for free shipping, before checkout, on the cart and on the product page. No surprises at the till.

Free shipping threshold
If you offer free shipping over a certain amount, that number should follow the visitor from the product page to the cart to checkout. A visible progress bar toward it lifts average order value and removes the shipping shock in one move.

Form Field Reduction

Every field is friction. Most checkouts ask for things they do not need, or ask twice. Collapse the address into as few fields as possible, use address autocomplete, auto-detect the card type, and never ask for the same information on two screens. When we audit a checkout, cutting fields is almost always the cheapest conversion win available.

Error Handling

A checkout that rejects a card or a field without explaining why loses the sale on the spot. Errors must appear inline, next to the field, in plain language, the moment they happen, not after the whole form is submitted. A declined payment should offer an alternative, an express wallet or a different method, not a dead end.

What good looks like
Express wallets are the first thing on the screen. Guest checkout is the default. Shipping cost is known before this step, never a surprise. The form is as short as it can be, with autocomplete doing the work. Errors are caught inline, in plain words, with a way forward. The visitor decided to buy in the cart. Checkout does nothing but get out of the way.
Stage 5, Strategy
11

Rebuild vs. Optimize

There is almost never a reason to rebuild. In every project I've worked on, optimization has been more valuable than a redesign. Every single one.

A rebuild feels productive. It isn't. It's months of work to end up with a store that has different problems.

What optimization looks like
Y Studios grew +$227,000 in 3 months through full store optimization, not a from-scratch redesign. We found the leaks, fixed them in order of revenue impact, and measured the lift. That is the pattern, on every store.

The Only Two Modes

1
One-time optimization
Identify what's costing the most revenue. Build a list of changes, anywhere from 10 to 70 depending on the brand. Execute them over 30 to 90 days, either progressively or all at once.
2
Ongoing optimization
Same process, repeated. Research, identify, plan, implement. That's it. There's no third option.

The One Exception: Premium Repositioning

The only time I redesign is when a brand needs to feel more premium. Not a rebrand, the colors stay, the logo stays. What I'm adjusting are the specific elements that signal quality:

Button rounding
Whether you use fully rounded buttons, sharp corners, or something in between, and whether you apply it consistently, has a measurable effect on how premium the brand feels. This is the only lens I use when a visual overhaul makes sense.

How I Audit Before Deciding Anything

On a first call, I run a light audit with the client, enough to show them what's wrong and where the obvious problems are. That's not the real audit.

After the call, I sit down for an hour or more, longer for bigger brands, and go through everything. And I always get access to the data. Looking at a store from the outside gives you an incomplete picture. You need analytics, conversion data, traffic sources. A full audit without data isn't a full audit.

What good looks like
A clear list of what's broken, ranked by revenue impact. A plan to fix it in order. No wasted months on a rebuild that solves the wrong problems.
Next

What this audit can't tell you

This checklist shows you what to look for. It cannot tell you which of these leaks is actually costing you money, or in what order to fix them. That needs your data: your analytics, your conversion numbers, your traffic sources. Two stores with the same checklist have different top three.

That is the difference between an opinion and a diagnosis. A checklist is best practices. A diagnosis is evidence, ranked by how much revenue each leak is worth on your store. When we run the research, we do not hand you a longer checklist. We hand you a scored list, 20 to 70 changes, with the top 3 pulled to the front and a launch order behind them. Proof, not opinions.

This is what evidence looks like
Y Studios grew +$227,000 in 3 months through full store optimization. Across our work we have documented over $500K in revenue lift, and we can tell you exactly which changes moved the number, because every one was measured against the same traffic.
