The Challenge
A B2B SaaS client came to us spending $18,000 per month on Google Ads with a CPA of $420 per trial signup. Industry benchmark CPA for this software category is $180-240.
Our Audit Findings
Issue 1 — Broken Tracking: Their conversion tracking was firing on page load rather than on actual form submission. This meant Google was reporting 3x more conversions than actually occurred, and Smart Bidding was optimizing toward phantom conversions.
Issue 2 — Single Landing Page for All Traffic: All campaigns sent traffic to the same homepage. Zero message match.
Issue 3 — No Negative Keywords: The account had fewer than 30 negative keywords and was matching to irrelevant searches.
Our Solution
Week 1-2: Fixed all conversion tracking via server-side GTM. Rebuilt negative keyword lists. Week 3-4: Built 4 dedicated landing pages matched to campaign intent. Week 5-8: Restructured campaigns into tightly themed ad groups. Week 9-12: Layered in tCPA bidding after gathering 30+ clean conversions.
Results After 90 Days
CPA dropped from $420 to $176 — a 58% reduction. Monthly conversions increased from 43 to 102 — a 137% increase. Total ad spend remained at $18,000 per month.
☀ Be Optimistic: The fix was not magic. It was clean data, proper structure, and patience during the learning phase.
