Your First 90 Days With a Marketing Agency: What to Expect
- Jul 6

You just signed with a marketing agency. Maybe it's your first one ever, maybe you're on your third after two bad experiences. Either way, you're wondering: when do I start seeing results?
It's the most common question we get at Brummble. Some agencies promise leads in week one. Others give you the classic "it takes time" without explaining what that actually looks like.
Here's the real version of what happens in the first 90 days with a marketing agency - including the parts that might make you uncomfortable.
Days 1-14: The Deep Dive
Here's what frustrates most business owners right away: a good agency doesn't launch ads on day one. If yours does, that's a red flag.
The first two weeks should feel like an interrogation. Your agency should be digging into who your ideal customer actually is, what your current lead flow looks like, what you've tried before, and what your real revenue goals are.
At Brummble, we spend these first weeks getting access to everything - your Google Business Profile, website analytics, social accounts, ad history, and CRM. We audit what exists before building anything new.
This phase feels slow. You're paying and nobody's running ads yet. But an agency that skips this step is guessing with your money.
Days 15-30: The Build Phase
Now things start moving. Your agency builds the infrastructure that drives results for months - not just slapping up a quick ad.
During this phase you'll see ad account setup or restructuring, landing page creation, tracking configuration, creative development, and audience research. This is also when your agency should set realistic KPI expectations.
The uncomfortable truth? If you're spending $1,500 a month on ads, you won't see the same results as someone spending $5,000. A good agency is honest about that.
One thing that surprises new clients: we're going to ask you to do stuff too. Photos, video access, copy approval, landing page feedback. The businesses that respond quickly always launch faster and perform better. Marketing is a partnership, not a vending machine.
Days 30-45: Launch and the Emotional Rollercoaster
Ads go live. Content starts publishing. Your Google Business Profile gets optimized.
And here's where the rollercoaster begins. Week one of a new campaign is almost always messy. Cost per lead might be high. You might get junk leads mixed in with real ones. You might look at the dashboard and think, "I'm paying for THIS?"
Deep breath. This is normal.
The ad platforms are figuring out who responds to your ads. Meta tests audiences, placements, and creative combinations. Google learns which search terms convert. This learning phase takes 7-14 days, and rushing it by making changes is the worst thing you can do.
Your agency should be monitoring daily but making minimal changes. They should be communicating what they're seeing - not going silent. If you don't hear from your agency for two weeks after launch, that's a problem.
Days 45-60: The Optimization Window
This is when a good agency earns their fee.
You've got real data now. The learning phase is over. A mediocre agency lets campaigns run on autopilot. A great agency is in the data every day:
Cutting underperforming creative and scaling winners
Refining targeting based on who's actually converting
Adjusting bids and budgets for efficiency
Mining search terms to eliminate waste
Testing new ad variations against top performers
Analyzing which leads become actual customers
This is where we typically see cost per lead drop and quality improve. We've seen accounts where CPL drops 30-40% between week two and week six from smart optimization.
The key metric isn't just "how many leads." It's the trajectory. Are things improving week over week?
Days 60-90: The Honest Conversation and Compounding Results
Around the two-month mark, you and your agency need a real conversation. Not "everything's great" - an honest assessment with specific data.
You should be asking what's working, what isn't, how you compare to similar businesses, and what the plan is going forward. Your agency should be asking about lead quality, your follow-up speed, and whether anything's changed in your business.
If your agency can't answer with specific data, that's a red flag. "We're working on it" isn't an answer. "Your CPL dropped from $45 to $28, here's what we did" - that's an answer.
By day 90, you should see a clear picture:
A functioning ad ecosystem generating consistent leads
Clear data on what works and what doesn't
Cost per lead that's stabilized or trending down
A strategy for scaling winners
An honest assessment of ROI
The Red Flags to Watch For
Not every agency relationship works out. Watch for these warning signs:
Your agency goes dark for more than a week
You can't get clear answers about where your money goes
They blame the algorithm without offering solutions
Three months in with no proper conversion tracking
Reports full of impressions and clicks but no mention of actual leads
What We Tell Every New Client
Marketing isn't magic. It's math, creativity, and persistence. The first 90 days are about building a foundation.
If you've got the right agency - transparent, data-driven, and actually invested in your results - the trajectory should be unmistakably upward by day 90. And if it's not? A good agency will tell you that too, along with a plan to fix it.
