Most founders treat a dip in ROAS as an ads problem. They tweak the creative, swap the audience, raise the budget and hope the algorithm figures it out. Sometimes that works. More often, the ads are doing their job fine and the store is what's killing the sale.
Before you spend another dollar on Meta or Google, run through this checklist. It's the same one we use on client stores before we ever touch a campaign. Twenty-five checks, split into six areas.
Shopify store speed checks to run before scaling ads
If this section alone turns up problems, it's worth a closer look. Here's more on how we approach page speed optimization on client stores.
1. Mobile load under 2.5 seconds. Most of your traffic is on a phone, often on a mediocre connection. Every extra second past 2.5 costs you buyers who never even see your offer.
2. Hero image compressed. A 4MB hero shot might look sharp on your desktop, but it's the single biggest reason first paint takes forever on mobile.
3. Unused apps removed. Apps you installed once and forgot about are still loading scripts on every page. Uninstall doesn't always mean the code is gone either, so check your theme files.
4. Fonts and scripts not blocking render. If the browser has to wait on a font file or a chat widget script before it shows anything, visitors are staring at a blank screen.

5. Offer clear in 3 seconds. A visitor should know what you sell and why it matters without scrolling. If they have to hunt, they've already left.
6. One CTA in the hero, not five. Multiple competing buttons split attention and none of them win. Pick the one action you want and make it obvious.
7. Trust signals above the fold. Reviews, press mentions, or a guarantee badge near the top tells a stranger it's safe to keep scrolling.
8. No dead sliders or broken carousels. Auto-rotating banners rarely get clicked and often hide your best message behind slides nobody waits for.

9. Real photos, multiple angles. Supplier stock photos are a red flag to anyone who's shopped online before. Original photos build trust fast.
10. Reviews near the top. If proof is buried at the bottom of a long page, most buyers never scroll far enough to see it.
11. Price and shipping cost upfront. Surprise shipping fees at checkout is one of the top reasons carts get abandoned. Say it early.
12. Variant selector works on mobile. Test this yourself on your phone. Broken size or color pickers quietly kill sales you never hear about.
13. Sticky add-to-cart on scroll. Once someone scrolls past the button, don't make them scroll back up to buy.
14. A bundle or upsell on the page. Even a simple "buy 2, save 10%" lifts average order value with almost no extra work.
Shopify cart and checkout audit checklist
This is usually the highest-leverage section to fix. See our checkout upgrade service if this is where your leaks are.
15. Shipping estimate shown in cart. Let people see the total before they commit to typing in their card details.
16. Express checkout enabled. Shop Pay, PayPal, Apple Pay. These cut checkout from a two-minute chore to a two-tap decision.
17. No surprise fees at the final step. This is the number one checkout abandonment trigger, and it's entirely avoidable.
18. Guest checkout allowed. Forcing an account creation before purchase adds friction nobody asked for. For a deeper dive on this whole area, see why cart abandonment starts increasing.
Trust and social proof checklist for Shopify stores
19. Real customer reviews. Placeholder or stock review widgets are easy to spot and they undo more trust than they build.
20. Return policy easy to find. Buyers look for this before they buy, not after. Hide it and you lose the sale, not just the return.
21. Contact info visible. A real email or phone number, not buried three clicks into the footer, signals a real business.
22. About page with an actual story. Generic "we're passionate about quality" copy convinces no one. Specifics do.
Shopify ad tracking checklist: pixel and GA4 setup
If tracking is broken, everything else on this list gets harder to measure. Related: our Facebook Ads service and how we handle pixel setup for clients.
23. Meta Pixel and GA4 firing correctly. Run a test purchase and check your events manager. Broken tracking means every optimization decision after this point is a guess.
24. Conversions API set up. Browser pixels alone miss a growing share of conversions thanks to ad blockers and iOS privacy changes. CAPI closes that gap.
25. UTM tagging consistent. If campaigns aren't tagged the same way across platforms, your reporting will never match reality.
What to do after you finish your Shopify store audit
Go through it store by store, not all at once. If you find five or more broken items, stop increasing ad spend until they're fixed. You'll get more out of repairing a leaky store than out of raising a budget that's pouring into it.
Fix the store first. Then scale into something that's actually built to convert the traffic you're paying for. If you'd rather have a second pair of eyes run this list, that's exactly what our website audit and strategy service does.
Frequently asked questions
Q1. How often should I audit my Shopify store?
Do a full pass every quarter, and a quick speed and checkout check any time you launch a new campaign or change your theme. Stores drift over time. Apps get added, images get swapped in without compression, a discount code app quietly slows checkout, and none of it shows up unless you look for it. If you're actively running ads, tie the audit to your ad calendar so you're never scaling spend into a store that's degraded since the last time you checked it.
Q2. What's the single biggest leak most stores have?
Checkout friction, usually a mix of surprise shipping costs and missing express payment options like Shop Pay or Apple Pay. Both are quick fixes with outsized impact on conversion rate. A close second is mobile speed, since most paid traffic lands on a phone first, not a laptop. If you can only fix one thing this week, test your own checkout on your phone with a real card and count how many extra taps or surprises show up before you'd actually finish the purchase yourself.
Q3. Do I need an agency to run this checklist, or can I do it myself?
You can run most of this yourself with free tools: PageSpeed Insights for speed, your own phone for the checkout flow, and Meta Events Manager for tracking. Where it gets harder is fixing what you find, especially theme-level speed issues or layout changes that need to work with conversion in mind, not just look good. Founders often run the audit fine on their own and then get stuck on execution, which is usually where outside help actually earns its cost.
Q4. How much does a broken store actually cost in ad spend?
More than most founders assume going in. A one-second delay in load time can cut conversions by double digits, and a broken checkout step can push cart abandonment past 70% on its own. If you're spending $2,000 a month on ads and a third of that traffic bounces before your page even loads, you're not buying customers at that point, you're buying data that trains your pixel to go find more people who won't buy either.
