Before Your Agency Touches a Single Ad: What a Real Paid Ads Agency Onboarding Process Looks Like
Most agencies skip straight to spending. Here is the 3-phase paid ads agency onboarding process we run before touching a single dollar of your budget.
TL;DR: Most paid ads agencies start spending before they understand your account. We run a 3-phase paid ads agency onboarding process (structured audit, 90-day plan, onboarding document, and daily monitoring) before touching a single dollar of your budget. Built from 4 years of partnership, $20M+ in audited ad spend, and 200+ accounts. The difference shows up in week one.
| Metric | Value |
|---|---|
| Ad spend audited | $20M+ |
| Accounts audited | 200+ |
| Years of partnership (Peterson + Cade) | 4 |
| Onboarding phases | 3 (audit, 90-day plan, monitoring) |
| Monitoring frequency | Daily, sometimes twice daily |
Before Your Agency Touches a Single Ad: What a Real Paid Ads Agency Onboarding Process Looks Like
Most paid ads agency onboarding looks like this: you hand over account access, someone runs a few initial checks, and campaigns go live within days. That feels like momentum. What it actually is is budget being spent before anyone has a clear picture of what is happening in your account, what is broken, and what needs to be fixed before optimization work even begins.
At Creekside Marketing, we run a structured, three-phase paid ads agency onboarding process before we write a single headline or adjust a single bid. This post walks through exactly what that process looks like, based on what Peterson and his partner Cade built after auditing more than 200 Google Ads and Meta Ads accounts and reviewing over $20 million in ad spend.
This post is based on a video Peterson published on the Creekside Marketing YouTube channel: Creekside Marketing Intro - 2026.
Phase 1: The Structured Audit Before Any Campaign Changes
The audit runs first, before we touch a single setting in your account. Most agencies use audits as a sales tool to justify taking over. We use the audit as a diagnostic, and everything we do for the next 90 days is based on what it finds.
On the Meta Ads side, Cade walks through a comprehensive checklist with every new client before making any changes. “We walk through this giant checklist in the audit, and we just show you, hey, this is what we structurally would like to change about your ads moving forward,” Cade explains in the intro video. The Google Ads audit follows the same logic. This process was developed after auditing dozens of accounts and refining the checklist based on what actually causes campaigns to fail at scale.
Specifically, the audit looks for:
- Structural campaign errors: Are campaign objectives actually aligned with what the business needs to achieve?
- Wasted spend: Are clicks converting to anything meaningful, or are they burning budget on traffic with no path to a sale?
- Tracking discrepancies: Is the conversion data feeding the platform algorithm measuring real outcomes, or is it tracking noise?
- Platform-specific compounding mistakes: Small misconfigurations that look harmless in week one and create serious drift by the end of a quarter
One principle is non-negotiable from day one: clients always own their accounts and have full access to everything we build. “You will always have access to all the accounts that we build for you,” Peterson says. We have seen too many businesses get burned by agencies and freelancers that hold account access hostage. The audit phase, and everything that follows it, is built on full transparency.
Phase 2: The 90-Day Plan That Sequences Every Change
After the audit, before anything goes live in the account, we build a 90-day plan. This is where most agencies skip straight to running ads, and it is the biggest structural mistake in how most paid ads management works. The plan sequences every change in the right order, because both Google and Meta Ads have learning phases where the algorithm needs clean, accurate signal before it can optimize effectively. Randomizing changes during that window corrupts the data and can add weeks to the timeline for getting real results.
“We come up with a 90-day plan of what we are going to do, how we are going to implement everything, and how you can expect to achieve better results,” Cade explains. The plan is not a marketing document. It is a structured rollout: what changes happen when, and what improvement you can measure at each stage.
The plan typically breaks into three windows:
Weeks 1 through 4 (foundation): The structural fixes from the audit go in first. Tracking architecture, campaign structure, audience setup. Nothing gets optimized until the foundation is clean and the data coming in is accurate.
Weeks 5 through 8 (build): Once the foundation holds, testing and optimization begin. This is where the data starts showing us what actually works for your specific account, audience, and offer.
Weeks 9 through 12 (scale signals): We identify what is producing results and build the case for scaling. Budget expansion decisions at this stage are based on real performance data, not projections.
The specialist model is central to this phase. “If you go with someone who says they are jack of all trades, typically that means master of none,” Peterson says. Peterson manages the Google Ads planning and Cade manages the Meta Ads planning in parallel. After four years of working together, those two plans are coordinated, not duplicated. Platform mechanics, auction dynamics, and optimization levers are fundamentally different between Google and Meta. One generalist trying to plan both simultaneously will miss things a specialist catches as second nature.
Phase 3: The Onboarding Document and the Paper Trail System
Once the audit findings are documented and the 90-day plan is confirmed, clients receive a structured onboarding document. This is not a welcome email or a generic PDF introduction. It is a specific checklist that walks through exactly how to share account access correctly, with a video walkthrough included, so there is zero friction between confirming the plan and actually starting work in the account.
“In that onboarding document you will just fill out a basic checklist of things of, hey, this is how you share access to Meta. There is also a video on there that tells you how to get access,” Cade explains. The goal is to eliminate all permission troubleshooting. By the time we are inside your account, we are working, not figuring out how to get in.
The monitoring system starts immediately after. This is the phase most clients never see and most agencies skip entirely, because it takes time to maintain and does not feel like a deliverable.
“I have this giant checklist of things that I do daily and sometimes twice a day, sometimes two times a week, where I make all the notes needed to leave a paper trail for your account,” Cade says. That paper trail is not an internal record. It is the accountability layer. When something changes in your account, there is a logged record of what was done, when, and why. Clear documentation is how you actually know what is happening inside your campaigns instead of receiving a monthly summary that tells you nothing actionable.
On the Google Ads side, Peterson runs a parallel management system. Each agency client and each direct client has its own tracking structure that keeps every account completely separated and documented. “This is how I keep everything separate, keep track of what I have been doing, keep track of what is important in the account,” Peterson explains. That separation is what makes it possible to manage campaigns across dozens of clients and industries without errors bleeding between accounts.
Why Conversion Tracking Is the First Thing We Fix in Any Account
Conversion tracking is always part of the Phase 1 audit, never a step that gets addressed after campaigns are live. Both Google and Meta Ads platforms optimize toward conversion signals, and if those signals are inaccurate, the algorithm learns the wrong patterns from the start. No bid strategy adjustment, audience refinement, or creative test can fix a platform that is optimizing toward corrupted data. The only fix is accurate tracking, and that has to happen before anything else.
“Having extremely good conversion tracking is very important,” Peterson says. “And so having someone that actually knows how to set that up properly is obviously very important. If you have bad data, you are going to have bad results.”
We use Google Tag Manager for conversion tracking setup on both Google and Meta campaigns. It is not an afterthought. The tracking setup is what allows each platform’s algorithm to learn, improve, and optimize toward outcomes that actually matter to the business.
This is where the engineering and accounting backgrounds Peterson and Cade bring show up directly in how they work. “We actually both got into marketing because we are incredibly good with numbers,” Peterson explains. “And we found that that is something that a lot of marketing agencies lack, the ability to find relevant data and find relevant insights in their marketing campaigns in order to improve upon them.” Peterson is a mechanical engineer by trade. Cade has an MBA and an accounting background. Identifying why something is happening in an account, not just what is happening, is a technical discipline for them.
What This Process Looks Like Across Agencies and Direct Clients
The three-phase paid ads agency onboarding process runs identically whether we are managing campaigns directly for a business owner or operating as a white-label paid media partner for a marketing agency. Scale does not change the process. Managing campaigns across dozens of clients simultaneously is what pressure-tested the process and forced it to become systematic rather than ad hoc.
We work with large agencies, including Duct Tape Marketing, where we serve as the Google and Meta specialists behind campaigns for their small business clients. We also work directly with business owners across multiple industries. The reporting, documentation, and paper trail system is the same in both cases, because the accountability requirement is the same.
Scott, who works with Creekside small business clients, brings more than five years of digital marketing experience from both in-house marketing teams and agency settings. The team structure means clients get relevant expertise matched to their situation rather than one person stretched across every context.
The results that came out of this process are documented in the Creekside case studies. Every case study reflects an account that went through the same structured onboarding described here.
Five Questions to Ask About Any Paid Ads Agency Onboarding Process
Before handing over account access to any paid ads agency, these five questions will quickly reveal whether there is a documented, structured process behind their work or just general familiarity with the platforms. Any hesitation on these questions tells you something concrete about how your account will actually be managed.
What does your audit cover, and will I see the findings in writing? A real diagnostic produces a documented output with specific findings. If the answer is vague or the audit is described as “a look at your account,” it is a checkbox exercise, not a diagnostic.
Do you build a 90-day plan before going live, and can I see what it covers? The plan should sequence changes in the right order and address the platform learning phase. If the answer is “we make improvements as we go,” there is no plan.
Will I always have full access to my own accounts? If there is any hesitation here, that is a direct red flag. You own your ad accounts, and an agency should never be a gatekeeper to your own data or account history.
How do you document what happens in my account each week? Without a monitoring checklist and paper trail, there is no real accountability for results. When something goes wrong, neither party can explain what happened.
Who specifically handles my Google Ads, and who handles my Meta Ads? If the answer is the same person for both, you are working with a generalist. Platform mechanics, auction systems, and creative requirements are different enough that specialization is a material performance advantage.
FAQ
How long does a paid ads agency onboarding typically take?
The audit, 90-day plan review, and onboarding document phase typically takes one to two weeks before any live changes go into the account. The monitoring system starts immediately after and runs continuously from that point forward.
Do you work with businesses that are already running ads?
Yes. Most of our clients come in with accounts already live. The audit is built to find structural problems inside running accounts, not just evaluate accounts from a blank slate. Some of the most significant findings come from accounts that have been running for months or years.
What if a previous agency did not give us access to our own accounts?
That situation comes up more often than it should. We always build accounts in client ownership, and the onboarding document specifically walks through how to get access set up correctly from day one, with a video walkthrough for Meta account sharing.
Do you work with marketing agencies as a white-label paid media partner?
Yes. We work as white-label paid media specialists for agencies who need dedicated Google and Meta expertise for their clients. Our reporting, documentation, and paper trail system is built to support that relationship and keep each client account completely separate.
What platforms do you cover?
Peterson focuses on Google Ads and Cade focuses on Meta Ads (Facebook and Instagram). Both follow the three-phase onboarding structure with platform-specific audit checklists and monitoring systems. The specialist model means each plan reflects platform-specific expertise, not a generalist approach applied to both simultaneously.
