Ad Spend Optimizer

Audits paid channel performance and recommends budget reallocation to lift ROAS and cut CAC.

Marketing & SEOIntermediate★ 145⑂ 29AI score 8/10Last updated: Apr 2, 2026

What it does

  • Computes ROAS, CAC, CPL, CTR and conversion rate per channel/campaign and compares them to healthy ranges.
  • Helps pick the right attribution model (last click, first click, linear, time decay, position-based, data-driven) for your sales cycle.
  • Reads marginal ROI signals to decide which channels have headroom to scale and which are hitting diminishing returns.
  • Builds three reallocation scenarios (conservative, moderate, aggressive) with projected leads, CAC and ROAS plus warning thresholds.
  • Sets up a weekly monitoring checklist and explicit scaling rule (15% below target for 2 weeks → +25% spend; above target for 2 weeks → −25%).

Who it's for

  • Performance marketers and growth leads doing quarterly paid budget planning.
  • Startup marketing owners diagnosing rising CAC or falling ROAS by channel.
  • Agencies and in-house teams wanting a 70/20/10 proven/test/experiment split.

Example uses

  1. "$100K/month split Google $50K, Meta $30K, LinkedIn $15K; 395 leads at $253 CAC vs a $200 target — model three reallocation plans."
  2. "Google Display is at $500 CAC, 2.5x my target. Should I cut it entirely, and where should that budget go?"
  3. "Design a TikTok test: budget size, success criteria, and the CAC threshold at which I kill it."
