How to Choose a Google Ads Agency: A Practical Hiring Checklist
Choosing a Google Ads agency means deciding who will manage your advertising budget, how you will judge their work and what happens if the partnership does not meet expectations. A polished pitch is useful, but the proposal needs to stand up to practical questions.
The right fit is an agency that understands your business model, explains its decisions and agrees on clear responsibilities. This checklist helps US ecommerce and service businesses compare providers before committing to a contract.
1. Define the business outcome before comparing agencies
Write a short brief covering what you sell, who you serve, your US target locations, your advertising budget and the problem you want to solve. Include any constraints, such as limited appointment capacity, seasonal demand or products with narrow margins.
For ecommerce, discuss sales alongside product margins, returns and acquisition costs. Revenue attributed to ads does not, by itself, establish profitability. For a service business, distinguish an inquiry from a qualified lead, an attended appointment and a paying customer.
Ask each agency which outcome it would prioritize and why. A proposal should explain how campaign decisions connect to that outcome, rather than treating more clicks as the end goal.
2. Look for relevant evidence and the people behind it
Ask for a case study that resembles your business in a meaningful way: a similar buying process, budget range, product category or service market. A recognizable client logo alone does not explain what the agency contributed.
Request the starting position, work performed, timeframe, advertising spend and method used to measure the result. Ask what else changed, such as pricing, promotions or the website. Results from one account provide context; they are not a forecast for yours.
Find out who will actually manage your account and who reviews their work. The person delivering the sales presentation may not be the person making campaign decisions.
A Google Partner badge reflects Google’s requirements for performance, spend and certifications. Review the current Partner requirements if an agency uses that credential. Treat it as one input alongside relevant evidence and the team’s experience.
Google’s badge guidelines prohibit implying that Google endorses an agency’s services. A badge is not a promise that your account will be profitable.
3. Agree on measurement and account access
Before approving a growth forecast, ask what the agency will count as a conversion and how it will test that measurement. For services, a click on a phone number is different from an answered call. For ecommerce, ask how purchase values and duplicate events will be checked.
Agree how campaign reporting will connect to your booking records, CRM or store. Reports should explain gaps and attribution limits, especially when multiple channels may influence the same customer.
Ask to retain direct administrator access to your advertising account. Google explains that linking a manager account to an existing client account preserves its history and does not grant administrative ownership by default.
If an agency requests manager ownership, ask which additional permissions it needs. Google recommends granting those privileges only when required; this setting does not transfer ownership of the client’s data. See Google’s explanation of client-account ownership. Also document who controls related analytics, tracking and product-feed accounts.
4. Get a written scope with named responsibilities
“Google Ads management” can describe very different services. Ask for the campaign types, markets and deliverables included in the proposal. Identify who handles tracking, ad copy, creative, product feeds and landing-page changes, and which items are outside scope.
Clarify the work your own team must provide. If new landing pages depend on your developer or lead-quality feedback depends on your sales team, build those responsibilities into the plan. Otherwise, a campaign can stall while both sides wait for the other.
When reviewing our own offering, use Digitalthrob’s Google Ads service page as a starting point and ask us to confirm the scope for your business. The same questions should apply to every provider you consider.
5. Compare the full cost, not just the management fee
Ask for a written breakdown that separates the agency’s fee from the money spent on ads. Confirm how the fee changes if spending increases and whether there are minimum charges or one-time setup costs.
Advertising spend: the amount budgeted for the ad platforms.
Management fees: the retainer, percentage-based fee or other agreed payment structure.
Additional work: tracking setup, landing pages, creative, feeds or reporting tools, where charged separately.
Contract terms: minimum commitment, notice period, renewal terms and charges payable on exit.
For illustration only, a $750 monthly management fee plus $350 per month in required add-ons totals $1,100 per month before ad spend. A $1,000 monthly proposal that includes those same items would cost less for that scope. These are hypothetical figures, not market benchmarks or Digitalthrob prices.
A lower total price still does not establish better value. Compare what gets delivered, who does the work and how you will assess its usefulness.
6. Ask how decisions and problems will be communicated
Request a sample report with confidential information removed. It should help you understand spend, measured outcomes, relevant lead or sales quality, significant changes and the next decisions. A dashboard full of numbers is only useful if someone can explain what they mean for your business.
Agree on the reporting schedule, your main contact and how urgent issues are handled. Ask who can approve budget changes and how those approvals will be recorded.
A useful interview question is: “Tell me about a campaign that underperformed. What did you investigate, what changed and what remained uncertain?” Look for a clear explanation of the work and its limits.
7. Agree on milestones, review dates and an exit plan
Replace a promise of results by a fixed month with specific deliverables and decision points. Early milestones might include reviewing the account, validating measurement, agreeing priorities and launching the first set of changes. Confirm which dates are commitments to complete work and which outcomes remain uncertain.
The time needed to judge performance depends on the starting account, available budget, conversion volume and the customer’s buying cycle. Ask what evidence would support continuing, revising or pausing the plan. Monitoring regularly does not mean changing every setting every day.
Before signing, document cancellation notice, final charges and the handover process. Confirm what happens to account access, campaign history, reporting files and creative assets covered by your agreement. Resolve unclear terms before the work starts.
Use the same comparison sheet for every proposal
Ask each agency to address the criteria below in writing. Mark each response as clear, needs clarification or missing, and record the evidence behind your assessment. Compare the same scope of work and resolve unclear answers before deciding.
Compare | What you should be able to identify |
Business fit | A relevant objective, audience and explanation of how success will be judged. |
Evidence and team | A contextual case study and the people responsible for your account. |
Measurement and access | Defined conversions, a testing plan and agreed access permissions. |
Scope and total cost | Included work, exclusions, ad spend, fees and required add-ons. |
Communication | A reporting schedule, named contact and budget-approval process. |
Review and handover | Decision points, cancellation terms and clearly assigned assets and access. |
Questions to resolve before you sign
What will you do first, and what information or access do you need from us?
What does a qualified lead or valuable sale mean for this account?
Which work and costs are excluded from this proposal?
Who can approve additional spending or changes to scope?
What will make us change direction, and what happens if we end the agreement?
You do not need an agency that claims to have every answer before seeing the account. You do need one that identifies what must be checked, explains its assumptions and takes responsibility for the work it agrees to perform.
