The

challenge

A fast-growing online store spent steadily on Google Ads but saw almost nothing back: three purchases in a month at $374 each.

Keywords were broad and often irrelevant, ad copy was generic, targeting ignored where and who the buyers were, and nobody was watching performance closely enough to fix it.

Our approach

What we did, in order.

01
Keyword Rebuild

Irrelevant and wasteful terms removed, replaced with transactional and long-tail keywords.

SEO process step 1, search position audit: hands reaching into a beam of light
02
New Ad Copy

Headlines, benefits and calls to action rewritten per product segment.

SEO process step 2, strategic roadmap: overhead view of a person on a bench
03
Targeting

Demographic and location targeting tightened around the people who actually bought.

SEO process step 3, execution and optimisation: people walking through a sunlit underpass
04
Tracking & Optimisation

Conversion tracking set up in GA4 and Google Ads, then weekly optimisation on CTR, conversions and CPA.

SEO process step 4, commercial insight: silhouette walking toward light at the end of a tunnel

The

result

Five months later, on almost exactly the same budget, the account delivered 18 purchases a month instead of 3. Cost per acquisition fell 84% from $374 to $61.25, and clicks more than doubled.

The budget was never the problem. Where it was going was.
