The client

A US-based e-commerce retailer selling automotive replacement parts — windshield wipers and vehicle-specific fitment, including a higher-margin RV segment. The Google Ads account launched in early 2026, so the work started from a young account with limited performance history rather than an established one.

The challenge

Grow revenue profitably from a standing start. The real question was where growth was actually constrained: by bidding and targeting, or simply by how much budget the account could absorb? Getting that diagnosis right is the difference between over-engineering an account and unlocking the lever that actually moves it.

The approach

• Segmented structure. Shopping split into core generic and high-margin RV lines, with Search covering vehicle make/model and brand terms — so budget and bids follow margin and intent instead of being averaged across the account.
• Diagnosed the real constraint. Across review cycles the enabled campaigns were consistently limited by budget-driven impression share, not by efficiency or quality. Spend was scaled deliberately against that constraint rather than chasing structural changes the data didn’t call for.
• Disciplined weekly reviews. A fixed cadence tracking spend, ROAS, impression share, search terms, keywords and ad strength — biased toward leaving strong campaigns alone and making only the changes the data justified.
• Match-type and negative-keyword hygiene. Exact and phrase match only, with negatives maintained to cut wasted spend on irrelevant queries and stop campaigns bidding against each other.
• Feed and policy diagnostics. Caught product-level Merchant Center disapprovals that standard reporting tools didn’t surface — protecting spend and keeping the diagnosis honest instead of blaming bidding for a feed issue.

The results

Over the latest 90 days versus the prior 90, the account scaled spend by roughly 2x while improving return — the hard combination to pull off. Revenue and conversions more than doubled, and cost per purchase fell as ROAS climbed.

Why it matters

Anyone can spend more; the skill is spending more while getting more back per dollar. Here, a ~95% increase in ad spend produced a 132% increase in revenue and a 19% improvement in ROAS — growth and efficiency moving in the same direction, driven by finding the account’s true constraint and managing it with discipline.
