Optmyzr is a genuinely good PPC workflow suite — rules, scripts, audits and reporting across six ad platforms, with fifteen industry awards to show for it. ROASt does one job instead: deciding where every pound of budget should go, with response curves fitted to your data rather than rules you write. This page is an honest look at which bottleneck you actually have.
Optmyzr isn’t a tool we’ll pretend is bad — it’s one of the most respected products in PPC, and for good reason. Three things it does well that any comparison has to start from.
Rule Engine, no-code PPC scripts, one-click optimisations, account audits and multi-platform reporting — across Google, Microsoft, Amazon, Meta, LinkedIn and Yahoo! Japan. Hundreds of thousands of connected accounts and a 4.7 average rating say the breadth is real, not a feature list.
Optmyzr’s philosophy is user-controlled automation: rules and guardrails you define, AI that enhances your workflow rather than replacing it. That respect for the practitioner’s judgement is rarer than it should be.
Budget pacing with AI-powered spend projections, automatic campaign pausing when a monthly cap is hit, and alerts straight into Slack or Teams. If overspend keeps you up at night, Optmyzr has thought about it properly.
A rule compares numbers you chose against thresholds you set — it’s only ever as good as the logic you wrote on the day you wrote it. ROASt’s engine fits a response curve to every campaign’s own spend-vs-return history and solves the allocation mathematically: each pound moves to its highest marginal return, every night.
The engine fits Hill response curves to each campaign’s spend-vs-return history — 91 days, recent days weighted more — and refits them nightly. Two campaigns with identical average ROAS can hide wildly different headroom; rules can’t see that, curves can.
Budget moves toward genuine headroom and away from saturation — where the next pound returns most, not where yesterday’s average looked best. That’s a calculus problem. No rule library solves it, however large.
A ROASt portfolio holds one budget and one goal across Google, Microsoft and Meta — and the engine moves money between platforms when the curves say so. Clients think in budgets and goals, not in account boundaries.
Every night the engine checks its own predictions against what actually happened and shows you the calibration score on your dashboard. Automation that grades its own homework in front of you is the difference between trusting a tool and hoping.
Optmyzr earns a long run of ticks here — it does many things ROASt deliberately doesn’t. The rows that matter are the ones where the two tools answer a different question.

Optmyzr column based on optmyzr.com’s public pages — homepage, pricing, budget-management and AI-info pages (checked June 2026). Optmyzr moves fast, so if anything here is out of date or unfair, tell us — [email protected] — and we’ll fix it.
A comparison page you can trust has to cut both ways — and against a tool this broad, the honest list is longer. Six reasons to pick Optmyzr over ROASt:
Optmyzr’s Rule Engine and no-code scripts are the category benchmark. ROASt deliberately has no rule builder — if writing your own automation logic is the point, that’s a dealbreaker, and it should be.
Optmyzr ships real bid-management tooling. ROASt moves budgets and CPA/ROAS targets and leaves keyword-level bids to the platforms’ smart bidding — a deliberate line we don’t cross.
ROASt moves money on Google, Microsoft and Meta. If a big share of your spend sits on Optmyzr’s other three platforms, ROASt can’t manage those budgets today.
Optmyzr’s report templates and scheduled delivery are built for agency client service. ROASt’s dashboards and AI-written briefs are for the people running the account, not for a client-facing PDF.
Ad text optimisation and testing are first-class Optmyzr features. ROASt watches creative fatigue and suggests pauses — it doesn’t write or test your ad copy.
Optmyzr is a Swiss-army knife with a decade-plus of sharpening. ROASt is a specialist — if you’d rather run one tool than two, the generalist wins on convenience.
The questions people actually ask when comparing the two.
Not feature-for-feature, and we won’t pretend otherwise. Optmyzr is a broad workflow suite; ROASt is a budget-allocation engine. If your day is built around rules, scripts, ad testing and client reporting, Optmyzr is the better fit. If the decision that actually moves your results is “where should the budget go?”, that’s the whole of what ROASt does — and some teams will reasonably run both.
Optmyzr paces budgets, projects month-end spend, and reallocates based on spend potential plus rules you configure. ROASt fits a Hill response curve to every campaign’s own spend-vs-return history, refits nightly, and solves the allocation at the margin — each pound goes where the next pound returns most, across platforms, inside one portfolio budget. Rules encode what you believed when you wrote them; curves track what the data does.
No, deliberately. Instead of asking you to write the logic, the engine decides and you set the guardrails: velocity caps on how fast budgets move, campaign locks, staged changes you can review before they push, a dry-run mode, and kill switches at every level. If you want to author your own automation, Optmyzr is genuinely better at that.
Google Ads, Microsoft Advertising and Meta — with GA4, Shopify and HubSpot as revenue sources, so the engine can optimise against the numbers you actually trust rather than platform-reported conversions. Optmyzr covers six ad platforms; we’d rather go deep on three than shallow on more.
Pricing is public: plans start at £119/$149 per month with a 30-day free trial and no card up front. Optmyzr’s plans are tiered by your monthly ad spend; see our pricing page for the full ROASt breakdown.
That’s the whole point of the product. Every recommendation decomposes into the exact factors that produced it, every action is logged, and the engine grades its own predictions against reality every night. Start with how the engine works — or run it in dry-run mode and watch what it would have done.
30-day free trial, no card up front — and a seeded demo workspace so you can see the engine’s working before connecting anything.
