176 Conversions at $2.82 CPA via Google Search

A business needed to generate high-volume conversions through Google Search Ads while keeping cost-per-acquisition as low as possible. The target: scale lead volume without sacrificing efficiency.

I built a precision-targeted Google Search campaign designed to capture high-intent traffic at the exact moment users were searching for the service. The approach centered on three core principles:

Keyword architecture: Structured campaigns around tightly themed ad groups with exact-match and phrase-match keywords to eliminate wasted spend on irrelevant queries.

Negative keyword layering: Aggressively filtered out low-intent and irrelevant search terms to keep traffic quality high from day one.

Ad copy testing: Ran multiple headline and description variations to maximize click-through rate and quality score, which directly lowered CPC.

The campaign ran on Google Search, targeting users actively looking for the service. I focused on:

Tight ad group structures with no more than 15-20 keywords per group to maintain relevance

Continuous search term report analysis to refine negatives and discover new converting queries

Bid strategy adjustments based on conversion data, shifting from manual CPC to target CPA once enough data accumulated

Landing page alignment to ensure the post-click experience matched the ad promise

176 conversions generated

$2.82 CPA, well below industry benchmarks

25.21% conversion rate, decimating standard industry averages

Consistent performance maintained through ongoing optimization

This campaign demonstrated that disciplined keyword management and relentless search term refinement can produce conversion rates most advertisers only dream about.
