Scaling paid search while reducing cost per lead
We turned inefficient campaigns into a profitable lead generation system.

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.
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
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.
The numbers that moved
- Cost per lead reduced by 42% in 60 days, sustained for 6+ months
- Qualified conversions up 196% with flat ad spend
- 3.8× return on ad spend, up from 1.4× pre-restructure
- Quality Score lifted from 4.6 to 8.2 average across top campaigns
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.
