How to choose a growth partner: the questions to ask before you sign
Choose the partner whose work you can check. Decide first whether you need strategy, execution or both, then ask every candidate the same questions about who does the work, what they measure, who owns the accounts, how you see the data and how you leave. Start with a paid audit or a small fixed-scope project, and keep every ad account, pixel and analytics property in your company's name from day one.
Decide what you need before you take a call
If you can't describe the job in a paragraph, every pitch will sound right. Write down four answers first.
- Strategy, execution or both. Strategy is choosing which customers, channels, offers and budgets to bet on. Execution is building campaigns, making creative, fixing tracking and shipping landing pages every week.
- Which channels. Name the one or two where your buyers already are, say Meta and Google Shopping for a DTC brand, or Google Search and LinkedIn for B2B SaaS. Judge candidates on those channels, not their favorites.
- How much senior time. A few hours a month of experienced judgment is a different purchase from 40 hours a week of hands-on work.
- What success looks like in 90 days. One business number, such as contribution margin from new customers or qualified pipeline, plus one leading indicator you check weekly.
Agency, freelancer, fractional lead or in-house hire?
I've left prices out because they vary too much by market and seniority to compare here.
| Option | What you get | Typical commitment |
|---|---|---|
| Agency | Specialists, tools and creative capacity | Monthly retainer, often with a minimum term |
| Freelancer | One specialist's hands-on time | Hourly, per project or monthly |
| Fractional lead | A senior lead who owns the plan and manages specialists | A set number of days a week or month |
| In-house hire | A full-time person building knowledge in-house | Employment, plus recruiting and ramp-up time |
When each one fits, and the main risk:
| Option | When it fits | Main risk |
|---|---|---|
| Agency | Proven channels that need media buying, creative and analytics at once | Senior people pitch, junior people deliver |
| Freelancer | One channel, a clear brief and someone in-house who sets direction | One person is a single point of failure |
| Fractional lead | You need direction and someone to run execution, part time | Limited hours, and someone else has to execute |
| In-house hire | Proven channels and a full-time job's worth of work | Hiring before you know what the job is |
My default order: buy senior judgment first, through an audit or a fractional lead, then decide whether execution goes to a freelancer, an agency or a hire. A full-time hire for a job you can't yet describe is the most expensive way to find out what the job is.
The questions to ask before you sign
Send every candidate the same questions in writing, so you compare answers, not pitches.
Who does the work week to week
Ask for the names and roles of everyone who will touch your account, how many other clients each one runs, and who joins your weekly call. Ask the person who pitched how many hours a month they'll personally spend on you. Put the lead's name in the contract, with the right to approve any replacement.
What they measure
Ask which number they'll report every month and which system it comes from. For a DTC brand you want contribution margin: revenue after product cost, shipping, payment fees, returns and ad spend, ideally split by new and returning customers. For SaaS and AI products, you want qualified pipeline and closed revenue from your CRM.
Platform ROAS and lead counts are easier to hit. Each ad platform counts conversions under its own attribution rules and doesn't see your margins or returns unless you send them, and a form can fill up with people who will never buy. More on this in how ROAS, MER and POAS differ.
Access and ownership
You own the accounts and the partner gets access. That covers ad accounts, pixels, Merchant Center, analytics, tag manager, the store and the creative files, including raw footage and usage rights for creator content. Give each person their own login, never a shared password, so you can see who changed what and remove one person cleanly.
Reporting and raw data
Agree the rhythm up front: a short weekly update on spend, results against target, changes and next steps, then a monthly review that ends in decisions. Ask for direct access to every ad account and analytics property, not just a PDF or a dashboard the partner controls. On Google Ads, Google's guide for advertisers says you have the right to know at least the clicks, impressions and total cost of your ads, and its third-party transparency rules require partners to give you your customer ID on request and to report Google's charges without their own fees mixed in.
Testing and creative production
Ask who makes the creative, how many new concepts they'll ship a month and how they decide a test is over. A good answer names a hypothesis, a budget, a stop rule and a winning metric tied to margin or pipeline, not click-through rate. Landing pages belong in the same plan, since paid traffic sent to a weak page wastes budget (see landing pages for paid traffic).
Contract length and notice
Read the exit clause before the proposal. Ask for the minimum term, the notice period and what happens on the way out: who removes their access, which documents and files you get, and whether there's any fee to get your own accounts back. The right answer to that last one is no. A short first term and clear notice protect both sides better than a long lock-in.
Pricing model
You'll see three models.
- Percentage of ad spend. The fee follows your budget, not your results, so every piece of budget advice carries a conflict. Say they find $10,000 a month of wasted spend. Cutting it takes their percentage of that $10,000 off their own fee. Good partners cut it anyway, but the structure works against them.
- Flat fee. You pay for a defined scope, so cost is predictable and budget advice is clean. The risk is scope drift, so write down the outputs: channels, creative volume, reports and meetings.
- Hybrid. A flat base plus a capped bonus tied to a number you both trust, such as contribution margin or qualified pipeline from your own systems. Don't tie it to platform ROAS, which can rise just by shifting spend toward people who were already going to buy.
Whatever the model, get fees and media costs on separate lines. On Google Ads, Google requires partners who charge a management fee to tell new customers in writing before the first purchase and to show the fee on every invoice.
References you can call
Ask for two current clients like you in model and stage, plus one client who left. Call them. Ask who did the work, whether the partner's numbers matched their own books, what happened in the worst month and how the handover went. If no former client will take your call, weigh that.
Who should own the accounts, and how does partner access work?
You should, on every platform. Create each account under your company, keep at least two admins of your own, and give the partner the least access that does the job.
- Meta. Create the ad account, pixel and catalog in your own business portfolio (formerly Business Manager), then give the partner's business access to each asset, with partial access or full control. Meta's help center says a new ad account created in a business portfolio is permanently part of that portfolio and can't be transferred out, so an ad account a partner creates in their portfolio stays with them. Meta's developer guidance describes the right setup: the customer owns its ad accounts and assets, authorizes the partner's business with the right access, and can revoke it.
- Google Ads. Open the account under your own Google login, then accept the partner's manager account link under Admin, Access and security, Managers. Linking an existing account doesn't give the manager administrative ownership by default. An account can have only one owner manager, and Google says client account users can always unlink it.
- Google Analytics 4. Keep the property in an Analytics account your company controls and add the partner at property level as an Editor or Marketer. Editors control property settings but can't manage users, and data restrictions can hide cost or revenue metrics. A property a partner built in their own account can be moved to yours with its data and settings, but the mover needs Administrator and Editor roles on both accounts, so you need the partner's help.
- Google Merchant Center. Add the partner under People and access with Standard access, which covers everything except managing people and adding or removing apps and stores. Agencies on Google's newer Merchant Center for Agencies request Admin or Standard plus performance and insights access, your admin approves, and you can remove them from the Partners section of People and access at any time. Google says that product is available on a limited basis.
- Shopify. Partners request collaborator access with a 4-digit code you share from Settings, Users, Security. You set the role and permissions before accepting, only the store owner or an Administrator can grant access, and collaborators don't count toward your user limit. Never hand over the owner login. When a project ends, remove the collaborator and generate a new code so old codes stop working.
What are the red flags?
- Guaranteed results. Google says no one can guarantee a #1 ranking on Google, and its advertiser guide says it isn't possible to guarantee a specific ad position. Treat a promised ROAS the same way.
- The partner owns your accounts. An ad account, pixel or analytics property in their name gives them a hold over you the day you want to leave.
- A long lock-in with no exit. A minimum term is normal. A long one with no notice period and no handover clause is not.
- Only platform ROAS in the report. If nobody connects spend to margin or pipeline, nobody is managing the business result.
- No raw data. Screenshots and PDFs you can't trace to the source. On Google Ads, refusing to give you your customer ID goes against Google's third-party policy.
- The pitch team disappears. If the people from the sales calls aren't on your account a month in, raise it then, not at renewal.
How do you start without a long commitment?
Before a retainer, pay for something with a defined deliverable: an audit, or a short fixed-scope project such as fixing conversion tracking or rebuilding one channel's account structure. You'll see how the partner works, and you keep the output either way.
A good audit deliverable contains:
- A tracking check: whether purchases or leads are counted once, and whether platform numbers reconcile with your orders or CRM.
- Unit economics by channel: contribution margin per order, or cost per qualified opportunity and payback, from your own data.
- An account review: where the money goes, what's wasted, how campaigns are structured and, for ecommerce, the state of the product feed.
- A creative and landing page review: what's been tested, what's tired and whether each page matches its ad.
- A ranked action list with impact, effort, an owner and a date for every item. A recommendation without an owner and a deadline is entertainment.
- A 90-day plan with the budget, people and tools it needs, which you could run with or without them.
- The working files, exports and queries, so a different team could start from it without a call.
A scorecard you can copy
Score each candidate right after the call. Give 2 points when an answer matches the middle column, 0 when it matches the last and 1 for anything in between. A 0 on ownership or on reporting and data is a no, whatever the total.
| Area | 2 points | 0 points |
|---|---|---|
| Who does the work | Named people, known caseloads, the lead joins your calls | A team with no names |
| What they measure | Contribution margin or pipeline from your systems | Platform ROAS or lead counts only |
| Ownership | You own every account and file, they get access | Accounts sit in their name |
| Reporting and data | Weekly numbers, monthly decisions, direct access | PDFs and screenshots |
| Testing and creative | Written test plan, agreed creative volume, files handed over | Ad hoc tests, files kept by them |
| Contract | Short first term, clear notice, handover clause | Long lock-in with no exit terms |
| Pricing | Flat or hybrid fee, fees shown apart from media | Fees unclear or mixed into media costs |
| References | Current clients like you, plus one who left | Testimonials only |
| First project | Paid audit or fixed-scope project | Retainer from day one |
