Scaling paid search while reducing cost per lead
The challenge

What the client was facing

The account was burning budget on broad-match traffic and mixed-intent ad groups. Cost per lead had climbed steadily for 9 months and the sales team was complaining that the leads coming through weren't ready to buy.

Conversion tracking was firing on every form submission — including spam — so the algorithm was optimizing toward the wrong outcomes and reinforcing the wrong audiences.

Our strategy

The plan we built

  • Full campaign restructure by intent and funnel stage
  • Tight keyword grouping with aggressive negatives
  • Landing page rebuild with strict message match
  • Enhanced conversions for leads + offline conversion uploads
  • Smart Bidding tuned to qualified-lead signals
  • Offer testing across audits, quotes, and consultations
Execution

What we actually implemented

We rebuilt the account from zero. Brand, high-intent non-brand, mid-funnel research, and competitor traffic were split into separate campaigns so each could be tuned independently. Search terms were audited weekly and roughly 30% of historical spend was reallocated by adding negatives.

Every ad group received a dedicated landing page with strict message match — the H1 mirrored the search query within the first five words, proof appeared above the fold, and a single repeated CTA replaced cluttered navigation.

We pushed CRM-qualified lead events back into Google Ads via offline conversion uploads, so Smart Bidding finally started chasing real customers instead of vanity form fills.

What this means

Translated into business value

The client unlocked profitable scale. Instead of needing a bigger budget to grow, every dollar of existing spend now produced almost three times more qualified pipeline — and the sales team finally stopped complaining about lead quality.

With tracking aligned to revenue, future budget increases compound on a system that already pays back, rather than amplifying waste.
