Features

Everything Bach does to defend your Meta ad spend.

This is the whole operator: a 100+ check audit, a creative-fatigue radar, budget reallocation, audience deduplication, tracking guardrails, and an agent that executes the fixes on Meta. Not a dashboard. Not a rules engine you babysit. The performance marketer that actually does the work.

One tool, not six

Bach replaces the whole patchwork you audit Meta with today.

One operator does the work of an audit spreadsheet, a creative-fatigue tracker, a budget-rules engine, an audience-overlap checker, a tracking monitor and a media buyer — and unlike any of them, it executes the fix.

Creative intelligence

Catch creative fatigue before it drains spend

Bach tracks each creative’s performance curve, flags the exact moment it tips, and drafts the next angle to test. In 2026, refresh cadence drives performance more than targeting — so catching fatigue early is the single biggest lever you have.

  • Per-creative ROAS, hook rate, hold rate and fatigue
  • Format, placement mix and CPM-trend analysis
  • A fresh angle suggested for every winner

Budget & bidding

Move budget to what converts — automatically

  • Spend reallocation with the expected lift attached
  • Budget pacing and dayparting checks
  • Bid strategy, cost caps and CPA-vs-target

Audience & overlap

Stop your audiences bidding against each other

Bach surfaces audience overlap, caps frequency on saturated audiences, and right-sizes your lookalikes and retargeting windows so you stop paying twice for the same shopper. Cart-abandoner and checkout-starter audiences typically convert far better than cold prospecting — Bach makes sure they get their own budget, not buried reach.

  • Audience overlap and saturation, quantified
  • Frequency capping on the audiences burning spend
  • Lookalike sizing and retargeting windows

Tracking & signal

Never optimise on broken signal

Bach watches pixel and Conversions API health, event and purchase coverage, attribution windows and deduplication — so Meta’s algorithm learns from clean data and your reporting matches reality. Brands that fully implement the Conversions API see around 19% more reported conversions; Bach makes sure yours is firing.

  • Pixel and Conversions API health
  • Event, purchase coverage and deduplication
  • Attribution windows and MER reconciliation

What should I scale this week?
Scale Retargeting 30d — it is running 41% under target CPA with room on frequency. I would move +$520/mo into it from Lookalike 1%.

Why it's different

Not another audit PDF you'll never action.

01

Your data, not benchmarks

Bach scores against your own 12-month account history — not a generic industry average — so every finding is real for your account.

02

Ranked by money, not metrics

Each issue is sized in recoverable spend, so you always fix the biggest leak first.

03

It acts — on your approval

Most tools hand you a report. Bach proposes the exact fix, and once you approve, executes it on Meta and keeps watching.
