How to Scale Amazon Ads in 2026 Like the Top Brands

When CPCs are rising and ROAS is sliding, the answer is rarely a bigger budget. It's a misallocated one. Here's the 10-lever audit Nectar uses to diagnose why Amazon Ads plateau — and the structural fixes that reignite scaling in 2026.

Key Takeaways {#key-takeaways}

• Misallocation, not under-funding, is the usual cause. Across our audits, 20%–60% of ad spend goes to search terms that have never converted.
• Exact match is the cleanest dollar you spend. In one audit, Exact wasted 2.54% versus 46.05% on Auto and 27.44% on Phrase.
• Use SQP to stop paying for sales you'd already win. Branded purchase share above ~98% means you're buying organic clicks at ad prices.
• ROAS is a campaign metric. TACOS, MOAS, and LTV ROAS are business metrics. Optimize to the right one or you'll cap your own scale.
• AMC is the lens that makes the other levers measurable. Path-to-purchase, NTB lift, and audience activation all live here.
• Year-round prospecting beats tentpole sprints. Demand built between events is what makes tentpoles compound instead of carry the business.

More than 70% of Amazon sellers now run paid ads to drive visibility, up from roughly 40% five years ago, according to Marketplace Pulse data cited in the 2026 Amazon trends report. The bar for "good enough" advertising has moved. But here's the catch: across hundreds of Amazon Ads audits Nectar has run, the plateau is almost never a budget problem. It's a structure problem.

At Nectar, we audit budgets from a few thousand dollars to tens of millions a year, and we see the same patterns on more than 90% of them. The brands that break through don't outspend the competition — they out-structure it.

"One of the most consistent patterns we see when brands hit a plateau is not actually always a lack of budget — it's misallocated spend." — Harriet Carson, VP of Advertising at Nectar

Key Audit Stats:

• 20%–60%: of Amazon ad spend wasted on non-converting search terms (Nectar audit analysis)
• 90%+: of audits surface the same 10 structural issues, regardless of brand size
• +27%: conversion-rate lift observed when PDPs are rebuilt for retail-readiness

The Nectar Scaling Audit: A 10-Lever Framework {#the-nectar-scaling-audit}

The Nectar Scaling Audit is our 10-lever diagnostic for diagnosing why Amazon Ads stop scaling and the structural fixes that reignite growth. The 10 levers cluster into 3 phases that mirror how a healthy account is built: reclaim wasted dollars, diversify the mix beyond Sponsored Products, then measure and sustain what actually grows the business.

Treat the phases as sequential. Reclaiming wasted spend (Phase 1) funds the diversification (Phase 2), which only pays off if you measure it correctly (Phase 3). Most brands try Phase 2 or 3 work without finishing Phase 1, which is why their new programs underperform.

Phase 1: Reclaim Wasted Spend {#phase-1-reclaim-wasted-spend}

Everything else compounds from here. If 30% of your budget is funding searches that don't convert, no amount of DSP or AMC sophistication will outrun the leak.

Lever 1 — Eliminate Wasted Ad Spend {#lever-1-eliminate-wasted-spend}

Across Nectar's audits, 20%–60% of Amazon ad spend goes to search terms that have never converted. The culprits are predictable: Broad match without strong negatives, and Auto campaigns without harvesting routines. Discovery is valuable — it surfaces new demand — but it should be a controlled environment, not the bulk of your scaling budget. Separate exploration from monetization; give discovery clear rules; graduate proven terms into tightly structured Exact environments.

Match Type Wasted Spend (real account audit):

Match TypeSpendSpend w/ 0 Conversions% Wasted Spend% Total SpendExact Match$35,584$9022.54%29%Auto$34,882$16,06346.05%28%Phrase Match$26,787$7,35027.44%22%Broad$14,775$3,58324.25%12%Product Target$11,064$1,86316.84%9%Grand Total$123,092$29,76224.18%—

Pro tip: Start with "10 clicks, 30 days, zero conversions, reduce bids 50%." Two weeks later, pause if still flat — or negate the search term if the underlying keyword is still relevant.

If you're a higher price-point product, raise the click threshold. Nectar's baseline across accounts is roughly one conversion per ten clicks; premium products often need more. Build the threshold into automated rules, not a manual quarterly cleanup.

Lever 2 — Use SQP to Stop Cannibalizing Your Organic Sales {#lever-2-sqp-stop-cannibalizing-organic}

Amazon's Search Query Performance (SQP) report in Brand Analytics is the most powerful diagnostic released since AMC. It shows impression share, click share, add-to-cart share, and purchase share at the search-term level — versus the rest of the market.

Three questions to ask SQP:

• Where is your purchase share already so high that incremental ad dollars are buying clicks you'd already win? A branded term at 99% share that drops to 98% after a 50% spend cut means competitors picked up a rounding error. That budget belongs against under-penetrated category terms.
• Where is search volume high, purchase rate is decent, but impression share is low? Exposure debt — the cleanest place to lean in.
• Where are you getting impressions but failing to capture purchase share? A conversion problem (price, reviews, PDP), not a media problem.

Pro tip: iDerive trends SQP over time so the answers to those three questions become a weekly view, not a manual download. The principle matters more than the tool.

Lever 3 — Shift to Exact Match for Proven Keywords {#lever-3-shift-to-exact-match}

Exact match isn't conservative. It's strategic. Once a search term has proven it converts, it deserves its own environment with full control over bids, budgets, and placement. There's a reason Exact consistently has the lowest wasted-spend percentage across our audits — surgical targeting beats spray-and-pray when the data is there.

The added benefit is compounding organic rank. When you consistently win auctions on high-intent queries, your organic ranking strengthens — which lowers future CPCs and grows purchase share without additional ad dollars. Discovery surfaces opportunity; Exact match scales it.

Single-keyword campaigns for top performers also unlock granular placement reporting (top of search vs. rest of search vs. product pages) so you can bid up where the highest-intent shoppers actually are. Keep some budget in Phrase and Auto for net-new discovery — but as the account matures, the ratio should tilt heavily toward Exact.

Phase 2: Diversify Beyond Sponsored Products {#phase-2-diversify-beyond-sponsored-products}

Once the leaks are sealed, the next plateau is format concentration. Most accounts we audit run 80%–90% of spend through Sponsored Products. That worked three years ago. It doesn't anymore.

"If you rely only on Sponsored Products, you're limited by existing search volume. If you rely only on DSP without strong search coverage, you may create awareness but fail to convert because shoppers can't find you." — Harriet Carson, VP of Advertising at Nectar

Lever 4 — Optimize Your Ad Format Mix {#lever-4-optimize-ad-format-mix}

Every Amazon ad format plays a different role. Sponsored Products captures existing demand. Sponsored Brands and Sponsored Brands Video influence consideration and reinforce positioning. Sponsored Display intercepts shoppers on competitor PDPs. DSP shapes demand earlier in the funnel and is the only format that reaches non-Amazon audiences before they search.

One Nectar audit illustrates the imbalance: 89.3% of spend in Sponsored Products returned 1.57× ROAS, while 6.1% in DSP returned 4.51× and a small Sponsored Display Product Target allocation returned 5.02×. Reallocating even 5–10 points of share moves the blended return materially.

Key benchmark: Shoppers exposed to multiple ad formats (Sponsored Products + Sponsored Brands, or Sponsored Products + DSP) convert at a higher rate than single-format exposure — a pattern measurable in Amazon Marketing Cloud's path-to-purchase reporting.

The optimal mix differs by category, budget, and portfolio depth. The principle doesn't: capture existing demand, influence shoppers in evaluation, and create demand earlier in the journey — then track the interplay in AMC so you know which combinations actually convert.

Lever 5 — Activate AMC Audiences & Insights {#lever-5-amc-audiences-insights}

Amazon Marketing Cloud (AMC) is the clean room that lets you analyze how shoppers move across your ad types — and a meaningful share of mid-market brands still aren't using it. The platform originally required SQL, which kept adoption low. That's no longer true: AMC ships with templated queries, lives inside the ads console, and is accessible to any account running Sponsored Ads — DSP not required.

The high-leverage plays inside AMC:

• Custom audiences — cart abandoners, lapsed customers (up to 5-year lookback), past Subscribe & Save dropoffs, brand-store viewers who didn't purchase
• Path-to-purchase analysis — which combinations of ad exposures lead to NTB, and which paths waste impressions
• NTB tracking for Sponsored Products — so you stop optimizing on attributed sales that are really repeat purchases
• LTV measurement for 1P brands — the only way to move Vendor Central conversations off ROAS
• Attribution model design and ad-exposed cohort analysis — multi-touch measurement that DSP straight-line ROAS will never show

One AMC path from a recent audit: shoppers exposed to SP → SB → DSP returned 4.8× ROAS at 82.55% NTB; the simpler SP → SB path returned 16.0× at 83.80% NTB. Without AMC, you can't see either pattern — and you can't allocate against it.

Pro tip: If your top competitors are using AMC and you aren't, the measurement gap widens every quarter — particularly on DSP, which can't be honestly evaluated on straight-line ROAS.

Lever 6 — Implement Product Targeting & Conquesting {#lever-6-product-targeting-conquesting}

At least 20% of the accounts we audit are running little to no product targeting. Not every shopper starts with a keyword — many start on a competitor PDP, comparing features, pricing, and reviews. Product targeting intercepts them at the consideration stage, where keyword targeting can't reach.

Defensive vs. Offensive Product Targeting:

Targeting TypeGoalTacticBest ForDefensive TargetingProtect your own PDPs from competitor takeoverRun Sponsored Products and Sponsored Display against your own ASINsBrands with strong organic traffic where competitors are bidding aggressivelyOffensive ConquestingCapture high-intent shoppers on competitor PDPsTarget competitor ASINs that are higher-priced, lower-rated, or have weaker contentBrands with pricing, review-count, or content advantages over a known competitor set

CPCs on product targeting are typically lower than non-branded keyword CPCs, and Amazon's auction gives bid preference to brand owners on their own PDPs — making defensive coverage cheap real estate to hold, and offensive conquesting a way to reach in-aisle shoppers without paying $10–$15 non-branded CPCs in saturated categories.

Pro tip: Watch how Defensive Targeting affects conversion rate on non-branded category terms. The whole reason to defend your PDP is so you don't pay for a click, lose the shopper to a competitor's PDP-overlay ad, and have to acquire them all over again.

Phase 3: Measure & Sustain What Works {#phase-3-measure-sustain-what-works}

The last four levers determine whether everything in Phase 1 and Phase 2 actually moves the business — or just optimizes the ads in isolation.

Lever 7 — ROAS Isn't Your North Star {#lever-7-roas-isnt-north-star}

ROAS is a useful campaign metric. It is not a business metric. High blended ROAS often hides over-reliance on branded traffic and retargeting — efficient on paper, not expanding the customer base. Optimize exclusively to ROAS and budgets drift toward the bottom of the funnel, capping acquisition and category expansion over time.

"If you only watch ROAS, you optimize a campaign. If you watch the full ecosystem, you optimize the business." — Harriet Carson, VP of Advertising at Nectar

ROAS vs. TACOS vs. LTV ROAS:

MetricWhat It MeasuresWhat It MissesWhen to UseROASAd sales / ad spend (campaign-level)Organic sales, halo lift, incrementalityCampaign-by-campaign efficiency checksTACOSAd spend / total sales (ads + organic)Profit, margin variation by SKUWhether ads are growing the business or just shifting organic to paidMOASMargin on ad spendLong-term customer valueProfit-first decisions on individual campaignsLTV ROASAd spend vs. customer LTV over 30/60/90/180 daysShort-term cash flowSubscribe & Save brands, consumables, CPG with predictable repurchase

A $10 ROAS at 10% TACOS is worse than a $3 ROAS at 7% TACOS if the second account is also higher-margin. You don't get paid in ROAS. You get paid in profit. Build dashboards that surface TACOS, contribution margin, and (for 1P brands) LTV — and have the finance conversation there, not at the campaign-level ACOS line.

Lever 8 — Segment Campaigns by Goals {#lever-8-segment-campaigns-by-goals}

Even well-funded accounts plateau when campaigns aren't role-segmented. The top-performing structures we audit separate the program into three distinct roles, each measured differently:

• Acquisition — high-intent category and competitor terms; dedicated campaigns so budget doesn't compete with branded or retargeting
• Brand defense — branded keyword and product-page coverage, optimized for efficiency, not absorbing scaling budget
• Retention / retargeting — cart abandoners, repeat-purchase windows, lapsed Subscribe & Save customers; isolated and tightly capped

Beyond role-based segmentation, segment by match type (Exact, Phrase, and Broad never live in the same campaign) and by product type. Without that structure, "branded spend" can balloon to 50% of total spend because Broad and Phrase are eating brand terms without the right negatives in place.

Pro tip: Pull a 90-day search-term report. Tag every term as branded, non-branded category, or competitor. If branded is anywhere near 50% of spend and you didn't design it that way, your negatives are the problem.

Lever 9 — Improve Conversion Rate {#lever-9-improve-conversion-rate}

Ads send traffic. PDPs convert it. A retail-ready listing makes every ad dollar more efficient — and PDP work is the single highest-leverage non-media improvement in most audits.

One Nectar benchmark: a category-leading pet brand saw a +27% conversion rate lift after Nectar rebuilt the PDP with clearer hero imagery, comparison content, sizing guidance, and benefit-led modules. That lift compounds every dollar of advertising afterward — and earns back the creative investment in weeks.

PDPs aren't one-and-done. Rebuild the foundation periodically on top-selling listings as search demand shifts and reviews reveal new objections. The brands that win treat PDPs as a quarterly cycle, not an annual project.

Lever 10 — Build a Year-Round Strategy {#lever-10-build-year-round-strategy}

Most brands plan around tentpole events — Prime Day, Black Friday, Q4 — and underinvest between them. Tentpoles concentrate margin pressure and don't compound. The brands that scale predictably treat tentpoles as accelerators, not rescues.

Consistent growth requires three structural commitments year-round:

• Always-on acquisition — prospecting layers active outside tentpole windows, especially for non-branded category and competitor terms
• Upper-funnel DSP — not just retargeting; awareness placements that feed AMC retargeting pools before the event
• Cohort building — NTB cohorts acquired in Q1/Q2 are the retargeting and Subscribe & Save universe for Q3/Q4

When demand is consistently created and captured year-round, tentpoles accelerate growth instead of rescuing it. Forecasting becomes predictable. The business becomes less vulnerable to a single bad event.

Your Quarterly Scaling Audit Cadence {#quarterly-audit-cadence}

The framework only works on a rhythm. For established accounts:

• Every month: Search-term reports for wasted spend. Negative-keyword sweeps. Bid-modifier reviews. Pause anything hitting the 10-click no-conversion threshold.
• Every quarter: Full Phase 1 audit — SQP analysis, Exact-match expansion, harvesting routines. Campaign-segmentation check to confirm branded share is intentional.
• Twice a year: Ad-format mix review. AMC path-to-purchase analysis. Product-targeting refresh.
• Annually: PDP rebuilds on top 20% of revenue-driving ASINs. North-Star metric review with finance. Year-round prospecting plan reset.

Frequently Asked Questions {#faq}

Why Do Amazon Ads Stop Scaling? {#faq-why-do-amazon-ads-stop-scaling}

Amazon Ads usually stop scaling because of structural misallocation, not insufficient budget. Across hundreds of Nectar audits, 20%–60% of spend funds search terms that never convert, formats run in silos rather than coordinated layers, and accounts optimize to ROAS instead of TACOS or contribution margin. Reclaiming wasted spend, diversifying the format mix, and switching to business-level metrics is what restarts scaling — usually on the same budget.

How Much Amazon Ad Spend Is Typically Wasted? {#faq-how-much-amazon-ad-spend-is-wasted}

Nectar's audits consistently show 20%–60% of spend going to search terms that have produced zero conversions over a meaningful lookback window. The biggest culprits are Auto campaigns and Broad match without strong negatives. A simple starting rule is "10 clicks, 30 days, zero conversions, cut bids 50%" — and pause two weeks later if still flat. Higher-price products may need a higher click threshold before the rule fires.

Is ROAS the Right Metric for Amazon Ads? {#faq-is-roas-the-right-metric}

ROAS is useful for campaign-level efficiency, but it's the wrong North Star for the business. High blended ROAS often hides over-reliance on branded traffic and retargeting, which doesn't expand the customer base. TACOS, MOAS, and LTV ROAS are the metrics that tell you whether ads are actually growing the business. The shift in conversation with finance is the harder lift — but the data is available, and the framing changes the strategy.

What Is Amazon Marketing Cloud (AMC), and Do I Need It? {#faq-what-is-amc}

AMC is Amazon's clean-room analytics platform for measuring cross-funnel attribution, building custom audiences, and analyzing incrementality. It's available to any account running Sponsored Ads, no longer requires SQL for templated queries, and lives inside the ads console. If your top competitors are using AMC and you aren't, the measurement gap widens every quarter — especially on DSP, which can't be honestly evaluated on straight-line ROAS.

When Should I Switch From Auto to Exact Match Campaigns? {#faq-when-to-switch-auto-to-exact}

Graduate search terms from Auto or Broad campaigns into Exact match as soon as the data proves they convert. A clean threshold is: a term with meaningful conversion volume over a 60-day lookback (or sooner for higher-velocity SKUs) gets harvested into a tightly structured Exact environment. Keep some budget in Auto and Phrase for net-new discovery — but as the account matures, Exact should dominate the share of converting spend.

How Do I Use Product Targeting and Conquesting on Amazon? {#faq-product-targeting-conquesting}

Run two flavors. Defensive targeting puts your own Sponsored Products and Sponsored Display ads on your own PDPs to prevent competitors from intercepting your traffic. Offensive conquesting targets competitor ASINs where you have a pricing, review-count, or content advantage. CPCs are typically lower than non-branded keyword CPCs, and Amazon's auction gives bid preference on your own PDPs — making defensive coverage cheap real estate to hold.

What's the Difference Between ROAS and TACOS? {#faq-roas-vs-tacos}

ROAS is ad-attributed sales divided by ad spend, measured at the campaign or aggregate level. TACOS is ad spend divided by total sales — organic plus ad-attributed — and is the cleanest measure of whether ads are growing the business or just shifting organic sales into the paid bucket. A $10 ROAS at 10% TACOS can be less healthy than a $3 ROAS at 7% TACOS, depending on margin profile. Build dashboards that surface both.

Where Do I Start If My Account Is Already at Scale? {#faq-where-do-i-start}

Start with Phase 1, even if the account is mature. Reclaiming wasted spend funds everything else, and an established account often has the most accumulated drift — old Auto campaigns, Broad terms without negatives, branded share that crept past 50% without anyone noticing. Once Phase 1 is clean, move to AMC and format diversification (Phase 2), then re-baseline your North Star metric with finance (Phase 3, Lever 7).

Scale Amazon Ads Like the Top Brands {#scale-amazon-ads}
