How to Choose a Digital Marketing Agency: 12 Questions to Ask Before You Sign

Choose an agency by asking questions you can verify: which business number they report, who owns the accounts, who does the work, and how you exit. Here are 12, with a check for each.
How to Choose a Digital Marketing Agency: 12 Questions to Ask Before You Sign
The way to choose a digital marketing agency is to ask questions whose answers you can check afterwards: who owns the ad accounts, which number they report against, who actually does the work, and how you exit. A pitch deck can't answer those, and the answers show you how the agency will behave in month four, not just in the sales meeting.
Most guides on this topic stop at "check their portfolio" and "set clear goals." Those are fine, but you already do that. This checklist is for a founder or marketing head who runs ads and content today and needs to separate agencies that look similar on a call. Each question below ends with something you can verify.
Before the calls: write down your own numbers
Pick the one result you'll judge the agency on, and write it down first. For a D2C brand that's usually blended CAC, repeat purchase rate within 90 days, or contribution margin per order. If you don't fix this, the agency will pick the metric that flatters its work. Our post on vanity metrics vs. real performance covers how to choose it.
Questions about measurement
1. Which business number will you report against, and what will you do if it doesn't move?
A good answer names orders, repeat purchase or margin, and describes what changes in the plan if the number is flat after a defined period. A weak answer lists reach, impressions and engagement. Check: ask for a sample report from a current client with the name removed, and see whether orders and revenue are on page one.
2. How will you set up tracking, and who will own it?
Attribution is where most agency disputes start. Platform dashboards and your store's order data rarely match, and someone has to reconcile them. Ask how they'd structure UTMs and GA4 before spending a rupee. Our guide to marketing attribution for D2C brands shows what a sound setup looks like, so you can judge their answer. Check: in week one, can you match a sample of orders in your Shopify or payment gateway dashboard to a tracked source?
3. What does "performance" mean in your proposal?
Some agencies mean a low cost per click. Others mean paid orders. Make them say which. We've written about the gap in conversion-optimized campaigns vs. reach . Check: the proposal should name the campaign objective in the ad platform (purchase or lead, not reach or traffic) for the spend that's meant to drive sales.
4. How do you treat repeat customers?
If the proposal is only about acquisition, you'll keep paying to win customers you already have. Ask what the agency does with email, WhatsApp and creative for existing buyers. See retention economics for why this matters. Check: a repeat-purchase rate you can pull from your own store, tracked monthly.
Questions about access and ownership
5. Will the ad accounts, pixel and analytics sit in my name?
They should. Google Ads is built so that an agency can work inside your account through a manager account, with its access levels labelled "(managed)" in Google's access-level documentation . Per Google's help page on access levels , a manager account that has ownership can also edit user access, managers and product links within your account. So ask who holds that ownership and admin role. Check: open your account's access settings yourself and confirm your own login is an admin.
6. What happens to the data and creative when we part ways?
Ask for it in writing: account access, raw creative files, audience lists and reports stay with you. This is a common gap in generic guides, including Moburst's , which has no contract or exit terms. Check: the contract names who owns each asset.
7. How do you handle customer data?
If the agency touches customer lists, phone numbers or order data, India's Digital Personal Data Protection Act applies to how that data is handled. The Act's schedule lists a penalty of up to ₹250 crore for failing to maintain reasonable security safeguards, as summarised by AM Legals . That penalty is framed around the data fiduciary, which is usually you, so a vague answer here is your risk. Check: ask where lists are stored, who has access, and whether a data-handling clause is in the contract. Have your lawyer read it.
Questions about the people and the work
8. Who will actually work on my account, and how many other accounts do they handle?
The team in the pitch is often not the team on the account. Ask for names, roles and hours per week. Check: a named lead for strategy, one for creative and one for media, with a stated weekly time commitment.
9. How does your creative get made and tested?
Performance depends on creative volume and variety as much as on bidding. Ask how many concepts they'll test per month and how they decide what to kill. If they only run campaigns, you may be buying media buying, not a content system. Our post on why D2C brands need a content engine, not a calendar explains the difference. Check: a written testing plan with a number of new creatives per month and the metric used to judge each one.
10. How do you work with creators, and who is responsible for disclosure?
Creator work often burns budget quietly. See our guide to a creator pipeline that doesn't burn your budget . On the compliance side, ASCI's code says ads must be clearly identifiable and that disclosures should appear upfront, and that advertisements must not mislead consumers or make claims that can't be substantiated. Check: ask to see a sample creator brief and confirm it includes the disclosure label and claim-approval steps.
Questions about money and terms
11. How do you charge, and what does it incentivise?
A flat retainer, a percentage of ad spend and a performance fee each push an agency in a different direction. A percentage of spend rewards spending more. A flat fee rewards doing less. A performance fee needs a number you both trust, which brings you back to question 2. Illustrative maths: on ₹10 lakh of monthly ad spend, a 15% fee is ₹1.5 lakh, and that fee rises if spend rises whether or not margin does. Check: ask for a scenario in writing: what does the fee look like if spend doubles and orders stay flat?
12. What does the first 90 days look like, and how do I exit?
Be wary of long lock-ins before the agency has proven anything. Ask for a defined 60 to 90 day review against the number from question 1, a notice period and what handover looks like. Check: the contract should state the review date and the exit notice in plain terms.
Run a paid pilot before the full retainer
Ask your top two agencies to run a small, time-boxed project against the same business number, such as a month of creative testing on one product line, or a tracking and reporting setup. Then compare the work on a scorecard of the 12 questions above, scored one to three. You'll learn more from four weeks of working together than from any pitch.
If you'd like a second opinion on a proposal, our performance analytics work covers the measurement setup behind questions 1 to 4.
Key Takeaways
Fix one business number (CAC, repeat rate or margin) before you meet any agency. Keep ad accounts, pixel, analytics and creative files in your own name. Ask who does the work, not just who pitches it. Fee structure shapes behaviour: test it with a "spend doubles, orders flat" scenario. Treat creator disclosure and customer-data handling as your risk, not just theirs. Run a paid pilot with two finalists before committing to a long retainer. FAQ
How do I choose a digital marketing agency for a D2C brand?
Start with the business number you'll judge them on, then ask the 12 questions above covering measurement, ownership, team, and terms. Prefer an agency that reports on orders and repeat purchase and lets you own the accounts.
What should I ask a digital marketing agency before hiring?
Ask which metric they report against, who owns the ad accounts and data, who will work on your account, how they charge, and how you can exit. Ask for a sample report with the client name removed.
Should I choose a full-service agency or a specialist?
It depends on whether your gap is a single channel or the whole system. A specialist suits a defined channel problem; a full-service partner suits a brand that needs content, performance and measurement joined up. Test either with a pilot.
Should the agency own my ad accounts?
No. The accounts, pixel and analytics should sit in your name, with the agency given access. Google's documentation describes agency access through manager accounts, so confirm you hold admin access yourself.
Is a long contract a red flag?
A long lock-in before any results is worth questioning. Ask for a 60 to 90 day review against your agreed metric and a clear exit notice period.
