How to choose an ecommerce PPC consultant: questions to ask

Choose an ecommerce PPC consultant by asking how they diagnose an account, verify purchase tracking, manage Shopping feeds, and decide where budget belongs. Confirm who does the work, what the fee covers, how you will communicate, and which accounts and data you retain. Relevant experience matters, but you also need a working arrangement your team can rely on.

Experience, certifications, and relevant client work can help you shortlist consultants. Use the first conversation to understand how they make decisions when tracking is unclear, products stop serving, or results fall short. The questions below help you compare their approach.

Ask how they start

A thoughtful consultant should ask about margins, inventory, goals, customer value, tracking, promotions, the catalog, and the account history before promising a result. If the first conversation is only about spend and a target ROAS, the diagnosis may be too narrow for ecommerce work.

Notice whether the consultant asks about margins, stock, earlier tests, and the problem you need to solve. Their process matters, but they should also explain how it would apply to your account.

Ask what they actually own

Clarify who will audit, build, edit, monitor, report, and communicate. In an agency, understand the handoff between the person selling the engagement and the person doing the work. In a solo practice, understand availability, response time, and how decisions are documented.

• Who makes account changes and who reviews them?
• Who owns feed and tracking coordination when the issue is outside the ad platform?
• How often will reporting and recommendations be reviewed?
• What happens if the account needs a pause, rebuild, or change in scope?

The handoff question matters more than it sounds. A common pattern in agency engagements is that the senior person who diagnosed the account and won your trust is not the person who touches it afterward. That is not automatically bad, but you should know it before signing rather than discover it in month three.

Ask about account ownership before you need the answer

Find out whose Google Ads and Merchant Center accounts the work will happen in, and what you keep if the relationship ends. The answer you want is that the accounts are yours, the historical data stays with your business, and nothing has to be rebuilt from scratch if you part ways.

Linking your account to a consultant's manager account is normal. Confirm that your business retains administrator access, and document ownership of tracking, data, and other assets. Get the handover process in writing before work starts.

Ask how they measure performance

The consultant should be able to explain primary conversions, value quality, attribution, brand demand, new-customer context, margin, inventory, and the limits of platform reporting. You do not need identical dashboards across systems, but you do need definitions that support a decision.

The strongest signal here is whether they volunteer the limits. Someone who explains that platform-reported conversions will not match your store, and why, and how they handle that gap, is someone who has dealt with the problem honestly. Ask for clarification if the explanation relies entirely on platform ROAS without discussing attribution or store results.

The ecommerce PPC tracking guide covers the checks worth asking about, and what a useful report should explain covers what you should expect to receive.

Ask how they handle Google, Microsoft, and feeds

The right channel mix depends on the account. Ask when they would recommend Search, Shopping, Performance Max, Microsoft Ads, a feed correction, or no new channel at all. The answer should include operational capacity and evidence, not just a desire to add more activity.

Ask when they would delay expansion or reduce activity. A useful answer explains the evidence they would need before adding another channel or increasing spend.

Understand how they charge, and what it rewards

A percentage of ad spend ties the fee to your budget rather than to the work or the result, which creates a quiet incentive to recommend spending more. A flat fee based on account complexity avoids directly tying the fee to media spend, though scope and incentives still need discussion. Neither model is dishonest on its own, but you should know which incentive you are buying and satisfy yourself that it points the same direction as your goals.

Ask what happens to the fee if the right recommendation is to reduce spend for a quarter. The answer tells you a great deal.

Look for clear communication

Good communication is not a high volume of updates. It is a shared understanding of what changed, why it matters, what is uncertain, and what happens next. Ask for an example of a recommendation that did not work and what the consultant learned from it.

A discussion of an unsuccessful test can show how the consultant handles uncertainty and changes course. If they cannot share client details, ask for an anonymized example or how they would handle a test that missed its goal.

Check the fit on working style, not just competence

Plenty of engagements end for reasons unrelated to skill. A brand that wants a weekly call and a consultant who works asynchronously will both be frustrated regardless of results. A team that wants a partner questioning the strategy and a consultant who executes instructions will misread each other constantly.

Ask directly how they prefer to work, how quickly they respond, and what a normal month looks like. A consultant who is clear about their model, including its limits, is easier to work with than one who agrees to everything in the sales conversation.
