A complete guide to understanding what an e-commerce PPC consultant does, when your business needs one versus a full agency, what to look for during vetting, and how a great consultant delivers measurable ROAS improvements.

For stores spending under $2,000/month on ads, the ROI on a consultant is marginal focus on self-education first. For stores spending $3,000–$5,000/month, a one-time audit ($500–$1,500) from an experienced consultant can surface improvements that pay back the fee within 30-60 days. Monthly retainers become cost-effective at $5,000+/month ad spend.
Track three metrics: ROAS trend over 90-day rolling periods, conversion rate trend, and cost per acquisition trend. A good consultant shows steady improvement across all three over 90-180 days. Flat metrics with lots of activity may indicate busy work without strategic impact. Request monthly reports that show these trends clearly.
A Google Ads manager focuses on day-to-day tactical execution bid changes, keyword additions, ad copy tests. A PPC consultant brings strategic oversight, account architecture decisions, cross-channel perspective, and business-level thinking. Many businesses benefit from both: a consultant setting strategy quarterly and an in-house manager executing daily tasks.
