Reducing Customer Acquisition Cost Using Google Ads Optimization

By re-architecting campaigns around SQL-value and killing wasted match-type spend, a mid-market SaaS cut CAC from $1,180 to $660 without losing pipeline.

A scale-up Fintech SaaS operating in the Fintech SaaS space.

• Cut CAC without giving up SQL volume.
• Reallocate spend from broad match to intent-locked terms.
• Bring SQL-value into Google as the primary conversion signal.

The team had inconsistent execution across channels, no shared dashboard, and no repeatable framework for prioritizing investment.

• No documented ICP or JTBD anchored to marketing programs.
• KPIs tracked in isolation, not tied to revenue outcomes.
• Tool sprawl with 4+ overlapping platforms and no single source of truth.
• Content and paid teams operating on separate roadmaps.

• Rebuilt account into intent-locked ad groups with tight negatives.
• Streamed offline SQL values into Google via enhanced conversions.
• Isolated brand into its own campaign with capped spend.
• Introduced a weekly wasted-spend review and negative-keyword sprint.

• Kicked off with a 5-day baseline sprint to map current state and quick wins.
• Locked scope for the first 90 days to prevent context switching.
• Ran a weekly 45-minute execution review — decisions only, no status updates.
• Stood up a live dashboard as the single source of truth for the leadership team.

• Sending SQL-value back into Google changed which auctions Smart Bidding chased.
• Broad match works only when your conversion signal is high-quality — most SaaS's isn't.
• PMax needs guardrails; unchecked it eats branded and reports the credit anyway.

• Skipping the audit phase to 'move faster' — teams later rebuild the same work.
• Confusing activity metrics with outcome metrics in weekly reviews.
• Running too many experiments in parallel to reach statistical clarity.

• Anchor every quarter to one primary outcome metric — everything else is a leading indicator.
• Run a monthly framework review — retire what isn't producing decisions.
• Give one owner accountability per workstream — shared ownership stalls output.

• Document ICP and JTBD before writing any brief.
• Publish a single KPI tree tied to revenue.
• Ship the dashboard before the first campaign.
• Run a weekly 45-min decision review with the DRIs.
• Retrospect every 30 days; adjust bets accordingly.
