How to Improve eCommerce ROAS: Should You Fix Your Ads or Your Store First?

Objection! Your ROAS is out of order.

Every eCommerce store trying to improve ROAS lands in the same argument sooner or later.

One camp blames the ads. The other blames the site. Both sides show up with a stack of proof, and neither backs down.

We have sat through this fight in more than 500 audits, and by now we know where the real improvement comes from.

Let's put both camps on the stand, hear the case each one makes, and settle how to increase ROAS for good. Grab a coffee. This one earns it.

eCommerce ROAS debate

The Case for Fixing Your Ads First to Increase ROAS

Camp A opens strong, and it opens with a fair point. If the platform is guessing at intent instead of knowing it, you are paying a premium for nothing but noise.

1. Give the Algorithm Better Signals

page data

Too many stores hand ad platforms weak clues and hope for the best.

You can build your own signals instead: funnel quizzes, exit surveys, preference centers dressed up as pop-ups. All of it feeds the machine better data than a pixel ever could.

Pair that with server-side tracking, tools like Meta CAPI, Google Enhanced Conversions, TikTok Events API, so the signal survives a blocked cookie.

And stop treating every visitor the same. A product page, a pricing page, a cart page each carries a different weight of intent. Your retargeting should know the difference.

2. Find More People Like Your Best Customers

Once you know who buys big, go find their twins. Pull your top 5% of spenders into a seed audience.

Build 1%, 3%, and 5% lookalike tiers, and run each one until it clears 5,000 impressions before you judge it.

Exclude anyone who bought in the last 60 days from awareness ads (they already said yes), and set up a referral loop that turns happy buyers into a recruiting arm.

3. Let Creative Carry the Weight

Here Camp A makes a confession that costs it a little ground, one we hear on almost every strategy call we run.

The algorithm is already better at finding buyers than a human targeting a demographic, full stop.

Creative decides most of the outcome now, sometimes more than 70% of it, according to Meta and Nielsen studies.

So the real work shifts: broad, story-led content for strangers; demos and reviews for browsers; urgency for shoppers who are almost there.

Change one variable at a time, swap the first three seconds of a video, and let the data pick the winner.

Good creative needs the right emotional angle too. Before you write a single line, map the feeling behind the purchase.

A skincare brand sells confidence, not serum. A snack brand sells trust in the ingredient list, not granola.

Once you know the feeling, build the hook around it: something like "feel proud of what you feed your kids" tends to outperform a straightforward ingredient callout in the split tests we run for clients.

Test the emotional version against the feature-led one and let click-through decide.

4. Test Spend Like the Budget Matters

A campaign that returns 4:1 at $100 a day can fall apart at $500. We see it happen all the time in the accounts we audit.

Split budget by funnel stage instead of dumping it in one pot, scale winners by 10 to 15% every few days rather than 50% overnight, and clone a strong ad set instead of editing it so you're comparing like against like.

Before you commit real budget to a new angle, test it somewhere cheap.

Niche platforms and specific subreddits give honest feedback at $20 to $30 a variant, a fair price to learn whether a hook works before spending the same amount ten times over on Meta.

Post the same clip as a normal, unpaid post and watch what happens.

If it earns shares and comments for free, it has told you it wants to be an ad.

5. Tighten the Map

Sequence your ads to match behavior. Someone who watched 75% of a video needs a different follow-up than someone who bounced off without scrolling, and testing placements matters as much as testing anything else, because the cheapest impression is often the least valuable one.

Geography counts too: twenty percent of locations tend to drive eighty percent of the profitable orders, and a tiered bid strategy built around that fact can cut cost by a third or more.

Good targeting cuts both ways. Exclude anyone who bought in the last 60 days from awareness campaigns; they already converted, and you're only paying to remind them of something they know.

Keep cart abandoners in their own segment instead of lumping them in with cold prospects, and cut anyone with a session under 10 seconds or a scroll depth under 20%.

Fewer of the wrong people saves as much budget as more of the right ones.

Placement deserves its own test too. Run Shopping, Search, and Video as three separate campaigns and track which one keeps shoppers past the cart page, not just which one earns the click.

Save Display and partner placements for reach campaigns only.

Down at the bottom of the funnel, an obvious ad format kills the sale before it starts, so stick to in-feed placements where the ad blends into the scroll.

6. Don't Skip Google Shopping

One channel deserves its own mention in our audits: Google Shopping.

It brings the most purchase-ready traffic of any ad channel out there, but only if the feed matches how people search rather than how a product manager wrote the spec sheet.

Swap a title like "Comfort Runner 5" for "Men's Arch Support Running Shoes, Comfort Runner 5, Ships in 24 Hours." The extra detail helps Google match the product to the right query.

Set feed-level promotions to auto-apply so the discount shows up in the cart without a code, and read the search terms report to catch which keywords are pulling in real orders.

And there you have Camp A's case in full: sharper signals, sharper audiences, better creative, disciplined spend, tighter targeting, a stronger showing in Shopping results.

All of it can increase ROAS. None of it touches the store.

The Case for Fixing Your Store First to Improve ROAS

Camp B doesn't dispute a single fact above. What they dispute is the order.

1. When the Landing Page Lies

The most common ROAS killer we find in an audit has nothing to do with the ad account at all. 

The ad promises one thing, the landing page delivers another, and trust breaks before the shopper finishes the second sentence.

Match the message. Add small interactions that reward attention. 

Show the reviews that fit the visitor's world, and build the whole thing mobile-first, with one CTA and a form that respects everyone's time.

None of this works if a shopper cannot tell you apart from the next tab. Look at customer feedback for the complaint that keeps repeating; it tells you what reassurance to lead with.

Check what competitors leave unsaid, then say it yourself.

And back the claim with a number instead of an adjective. "100+ product tests" does more convincing than "quality you can trust" ever will.

2. Give Shoppers a Reason to Stay

Close to two-thirds of your shoppers browse the web every week. Time on site, in other words, is not a vanity number for your store.

Put the social proof where it belongs, sharpen the filters, surface the one fact a product page can't survive without, and offer reassurance right where the checkout button lives.

Personalize the offer using what the shopper already showed you: what they browsed, what they abandoned, what season it happens to be.

Location can do some of this work for you too.

Show winter coats to shoppers in Colorado and lightweight layers to shoppers in Nevada, straight from the same catalog.

Trigger a message when someone is near a warehouse ("order today, get it by tomorrow" tends to work), and show the payment method a region prefers if the store sells across borders.

A "chat in..." option at the top of a live chat window turns a hesitant visitor into a comfortable one, more often than you would expect.

Get the nudge right, and it does more work for you than a straight discount ever could.

A live note reading "Sarah from Austin just bought this" reassures a first-time buyer better than any trust badge.

Skip the fake countdown timer. Use "only 3 left" instead, because honesty about scarcity holds up better than theater over time.

And put the bestsellers where the eye lands first: visual hierarchy does more of the selling than most stores give it credit for.

3. Fix the Phone Before You Blame the Feed

Two out of three of your orders start on a phone now, not later, not someday.

A store that isn't built for that taxes every dollar of ad spend without anyone noticing.

Responsive layouts, one-handed navigation, forms that use the right keyboard, and a checkout with one page instead of six will do more for ROAS than another week of audience testing.

4. Make It Easy to Ask a Question

A shopper with an unanswered question does not convert, they leave. A short quiz, "what's my size," "what's my skin type," turns hesitation into a recommendation.

A "chat with an expert" option, complete with the expert's name and a note on when they are online, builds real trust, more than a generic support widget ever manages.

WhatsApp meets shoppers on a channel they already trust, and a visible link to an active community group gives new visitors social proof before they even reach the product page.

5. Earn Trust From Strangers

Glossier Welcome Email Example

An ad can put a stranger in front of your product. Strangers, though, don't buy on faith. Show them your bestsellers.

Let them build a bundle instead of guessing at one blind.

Give first-time visitors an offer that says welcome, and write a welcome email that states what the brand believes before it ever asks for a sale. 

Glossier's version of this email sells a worldview first and a product a distant second, and it works.

Trust builds faster when a real person does the talking, not a script, something we see again and again in the accounts we work on. 

A founder addressing a specific objection on camera, or a customer's unscripted unboxing, reads as more honest than a polished ad, and platforms often reward that honesty with a lower cost per click.

Keep the same story across every touchpoint. If the ad features a customer clip, the landing page should carry that clip alongside a few more reviews, not some generic banner nobody asked for.

Every brand we've audited that keeps its ROAS healthy over the long run shares one habit: it tells a story shoppers want to be part of.

Talk about the impact a purchase makes, a donation, a sourcing choice, a founder's reason for starting the company in the first place.

Outdoor Voices built its whole identity around "doing things for fun" instead of performance, and that story now carries a share of the selling no ad could ever manage on its own.

6. Make Seasonal Moments Count

seasonal marketing example

Seasonal spikes are the easiest ROAS wins on the calendar, provided the on-site experience matches the moment.

Build gift guides and holiday content that point straight at the relevant products instead of a generic homepage.

Cross-sell around the season itself, the way Wayfair's St. Patrick's Day page groups festive decor, table linens, and outdoor pieces into one obvious next click.

Seasonal gift cards and quantity-based offers round out the push. A shopper already in a giving mood needs less convincing, not more of it.

7. Let SEO Pick Up Some of the Bill

Every visitor who finds your store through search is a visitor who didn't cost you a media dollar, which is reason enough to build the content in the first place.

Structure content around the questions shoppers type into the search bar: FAQs, comparisons, how-to guides, the format search engines feature first.

Long-tail, specific content pulls in more qualified traffic than a broad keyword ever will.

A well-built comparison page, your products against each other or against a competitor's, often converts better than a standard category page, because it answers the question a shopper was already asking.

8. Change the Math With Retention

This is Camp B's strongest exhibit, and Camp A conceded it earlier without noticing.

Lift average order value from $50 to $75 through a one-click upsell, and you can bid 50% more on acquisition while holding the same target cost per sale.

Bundles, premium upgrades, and milestone offers for repeat customers move the denominator in the ROAS equation, not just the numerator, a trick no ad account can pull off on its own.

ROAS alone can mislead a team into underinvesting in the customers who matter most. Build cohorts from your CRM by source channel and first product bought.

Then set acquisition cost targets against six-month lifetime value instead of day-one revenue.

A segment worth $150 over six months can justify a $50 acquisition cost, even if the first order does no better than break-even on its own.

Layer in retention triggers on a set schedule: an onboarding note on day 7, a loyalty invite on day 30, a subscription offer on day 45. That's how predicted high-value buyers become one.

Not every discount helps. The right kind, though, closes fast.

Quantity and tiered pricing reward a shopper for buying more without feeling like a trick.

Bundles that "complete an experience" sell better than random product pairings ever do, and a flash sale reserved for repeat customers creates urgency without training new shoppers to wait around for a discount code.

9. Borrow Camp A's Best Data From the Store

Some of Camp A's sharpest inputs, in our experience, are born on-site.

A one-click post-purchase survey, something as simple as "where did you first hear about us," often reveals a budget mismatch no ad dashboard would ever catch alone.

The classic case: 35% of buyers name TikTok, while the brand sends it 10% of the budget. Camp B rests its case as well.

The store is the multiplier on every dollar the ad account spends, from the first landing page a stranger sees to the loyalty email that brings them back, and it remains the most reliable way to improve ROAS without spending another cent on media.

The Verdict: How to Increase ROAS the Right Way

Both camps argued their case well, and the real split was never ads versus site.

It's predictable versus unpredictable, and that distinction sits at the center of every ROAS optimization strategy worth running.

Predictable Beats Unpredictable

Store fixes are cheap, within your control, and, in our experience, they keep paying out on every visitor who lands on the page, no matter which channel sent them.

Ad fixes work too, and Camp A's tactics deserve a real place in the plan, but they are rented gains at best. Stop paying, or watch the algorithm shift, and the improvement can vanish just as fast.

The Playbook We Run to Increase ROAS

Fix what you own before you scale what you rent, the first thing we tell every client. Use Camp B's tactics to lift conversion rate and order value first.

Then bring in Camp A's targeting and creative discipline against a store that's ready to earn the extra traffic.

Let owned channels, email and SMS, take the first shot at a visitor before retargeting spend kicks in.

That's both camps' evidence, working the same case, in the right order, and it's the shortest path we know to increase ROAS without increasing the risk attached to it.

Last Word

Ninety-eight percent of eCommerce visitors leave without buying. In our experience, the ads get blamed for what the UX broke.

Camp A and Camp B both make a fair case, but the store is the cheaper fix, and it pays out first.

If you want a second opinion on which camp is right for your business, that's the audit we run every day, as an eCommerce ROAS improvement agency built around improving ROAS for online stores.

Frequently Asked Questions About ROAS Improvement

What Is a Good ROAS for eCommerce?

There's no universal number here, whatever the averages you find online might suggest.

Your real target sits where margin, purchase frequency, and cash flow all meet. A 20% margin needs 4:1 to 9:1 just to break even.

A 50 to 80% margin can turn a profit at 3:1. A consumable with repeat buyers can work at 2:1 to 3:1, because customers return on their own without another ad.

A $200 item bought once every few years needs 3:1 to 5:1 to earn its keep.

Why is ROAS still low if we did everything right?

In our audits, five causes tend to show up again and again. Targeting that doesn't match the message. A landing page that doesn't match the ad.

A price that doesn't match perceived value. Ad copy that sounds like every competitor's. And missing trust signals at the exact moment a shopper needs one.

What are the leaks nobody notices?

These are the leaks we see most often in the audits we run. Weak follow-up after the first purchase. Ads that list features instead of naming a real reason to choose you.

Abandonment concentrated near checkout instead of earlier in the funnel.

Broken event tracking sending bad signals to the platform since iOS 14 arrived. A/B tests that change a headline but leave the actual offer untouched.

How is ROAS different from ROI?

ROAS is revenue divided by ad spend: a measure of advertising efficiency, nothing more.

ROI is revenue minus total cost, divided by total cost: a measure of whether the business as a whole turns a profit.

A campaign can post a strong ROAS and still lose money once fulfillment, returns, and overhead get counted in.

Which ROAS Optimization Strategies Should I Try First?

Start with the fixes you already own: landing page alignment, mobile checkout, trust signals, the same list we start with in every audit.

These ROAS optimization strategies compound on every visitor without adding a cent of media spend.

Layer in audience and creative work on the ad side once the store converts the traffic it already earns.

Store first, ads second: that order is the fastest route we've found to increase ROAS without adding risk to the budget.
