Google Ads
The widest auction surface, with the most learning-phase quirks. Search, Performance Max, and Shopping each get their own ceiling.

Learning-phase lock
Multi-platform PPC, built for the agentic era.
ROASt runs your portfolios on a statistical engine that understands marginal ROAS — supported by nine specialised agents and full MCP integration. Scroll through Day 1 with us.
[ 01 ] CONNECT — 10:04
Connect everything. Fix what's broken.
Google, Microsoft and Meta in one OAuth flow — campaigns, budgets and conversion actions pulled automatically. ROASt audits every account on connect and auto-fixes broken conversion setups; anything it can't fix is flagged with a one-click resolve.
[ 02 ] MODEL — 14:31
Marginal ROAS, made visible.
Hill response curves are fitted per platform and campaign, re-fitted nightly. The engine never asks “what spent well?” — it asks “where does the next pound work hardest?” The slope of this curve is that answer, at every level of spend.
You log off. ROASt clocks in.

[ 03 ] OPTIMISE — 02:14
While you sleep, budgets move.
Marginal-ROAS scoring redistributes campaign budgets every night to maximise performance against your goals — platform defaults, GA4, Shopify or straight from your CRM. Approved changes flow back to the platforms via their APIs. No spreadsheets. No 2am logins.

[ 04 ] THE TEAM — 03:30
Nine specialists on the night shift.
Three Optimisers act on your account. Three Watchers alert you to change. Two Analysts explain the numbers — and Flume, a generalist you can talk to in plain English. Claude where it helps. Deterministic math everywhere else.
[ 05 ] MEASURE — 07:00 TUE
Wake up to work done. Summarised.
Every push is observed against actual outcomes — the engine grades its own predictions, and confidence compounds with every cycle. Your morning brief lands at 7am, client-local: KPIs, what changed, what to act on. One page, ready to forward.

Tailored to how ad platforms actually behave.
The engine is pure math and modelling, no LLM involvement — which is how it should be. Platform adaptors are trained on platform behaviour and apply nuance and safeguarding to campaign scoring.
