Amazon advertising has never been moreexpensive — or more necessary. Average cost-per-click on Sponsored Products hit$1.12 in 2025, up roughly 15% year-over-year, and over 70% of active sellersnow run paid campaigns compared to 40% five years ago. More competition, higherCPCs, and thinner margins mean the average seller is now running an ACoS ofaround 30% — often without knowing whether that number is actually profitableonce organic sales are factored in.
Most sellers respond to this pressure one oftwo ways: they spend more, or they spend smarter. Spending smarter meanschoosing a platform that optimises for profitability — not just clicks — andthat treats paid and organic performance as a single system rather than twoseparate problems.
That's the real question behind the m19 vsPerpetua comparison. Both platforms automate Amazon PPC. But they makefundamentally different bets about what Amazon sellers actually need. Which oneis right depends on where you sell, how much you spend, and whether your teamhas the bandwidth to extract value from a more complex platform.

To put the difference inconcrete terms: a seller spending $20,000/month on Amazon ads would pay m19approximately $1,079/month on the Professional plan ($479 + 3% of $20K). OnPerpetua's Growth plan, the base fee is $695 plus a percentage of spend above$10K — the exact percentage requires a direct conversation with their salesteam.

m19
"8months in, our key lines have grown in velocity and ACoS consistently landsbelow target. The team actually told us we didn't need the more expensive plan.That kind of integrity is rare." — Trustpilot — UK seller, 2024
"We have been using M19 for above 2 years now and are very satisfied. It is very intuitive and the datas + dashboards available on the platform allow us to better decision fast and track very througly our spending." — Trustpilot — UK seller, 2024
Perpetua
"Asowner of a marketplaces agency, I've worked with different advertisingsolutions. Perpetua is still my favourite — the number of features is great andthey're constantly rolling out new ones." — Trustpilot — Agency owner, June 2024
"MyAmazon account was terminated. They still insisted on charging me under theannual contract — despite written confirmation from both Perpetua and Sellicsthat no further charges would follow." — Trustpilot — Verified review, contract dispute, 2024
Amazon DSP: Programmatic at Scale
DSP is Amazon's programmatic advertising channel — display, video, and audience-based targeting beyond sponsored ads. It's increasingly important for full-funnel campaigns, and the two platforms treat it very differently.
Included in Professional — no separate add-on needed
Retargeting, product targeting, and contextual audiences managed by AI
DSP spend factored into the same TACoS framework as SP/SB — paid and organic stay aligned
AI-driven setup built on proven agency playbooks, ready in minutes
No minimum spend requirement
Display campaigns only — Prime Video ads not included
Strong DSP offering, especially for enterprise managed-service accounts
AMC integration — audience building using first-party purchase data
CLTV audience segments for high-LTV retargeting
In-platform creative builder for responsive ecommerce and video formats
Covers Prime Video ads
Full feature set primarily available at enterprise or managed-service tier
For most Amazon-focused sellers, m19's integrated DSP keeps your programmatic and search campaigns in the same optimisation framework. Perpetua's DSP strength lies in its AMC-powered audience capabilities — most valuable for large brands with significant first-party data.
Which Platform Fits Your Situation
Neither tool is universallybetter. The decision comes down to where you sell, what you spend, and how muchinternal capacity you have to manage a complex platform.
Your primary channel is Amazon (EU or NA)
You want predictable, fixed-fee pricing with no percentage-of-spend surprises
Organic rank is material to your revenue — you want PPC to protect it, not erode it
You run an agency and need transparent pricing to build a client billing model
You want to launch in under an hour — no PPC expertise required, no credit card for the trial
You actively sell on Walmart, Instacart, or Target alongside Amazon
Monthly ad spend exceeds $50K and you need AMC-depth analytics for senior reporting
You need Prime Video ads or AMC audience building using first-party purchase data
You have an in-house team with time to invest in onboarding a more complex platform
Creative tooling (video ads, display builder) within a single platform is a priority
Where to Start
If your business is Amazon-firstand you want to test before committing, m19's Autopilot plan has a 30-day free trial with nocredit card required — setup takes under an hour with no PPC expertise needed.For the Professional plan, you can start a free trial here, or request a demo if you're an agency or managing largerad spend.
If you need multi-marketplacecoordination, Prime Video ads, or enterprise-level AMC audience capabilities,Perpetua is worth evaluating — but request a clear breakdown of contract termsand total cost at your spend level before signing.
