What to Expect in Your First 90 Days With a Marketing Agency

So you've signed the contract. Now what?

Hiring a marketing agency for the first time is exciting, but it can also feel a little daunting. You've made a financial commitment, you have big goals, and now you're wondering: how long before I see results? What should be happening right now? Am I getting my money's worth?

These are completely normal questions. The truth is, the first 90 days of working with a marketing agency look very different to what most business owners expect. Results don't happen overnight, but that doesn't mean nothing is happening. In fact, what takes place in those early weeks lays the entire foundation for your long-term success.

Here's a clear, honest guide to what you should expect, month by month.

Month 1

Month One: Discovery and Foundation (Days 1–30)

What this typically looks like:

  • Onboarding calls/meetings — Your agency will want to speak with key people in your business. Expect questions about your target audience, your sales process, what's worked in the past, and what hasn't.
  • Audits — A thorough review of your existing website, SEO, social media channels, and any paid advertising accounts. Think of this as a health check before treatment begins.
  • Competitor research — Understanding who you're up against and where the opportunities lie in your market.
  • Goal setting and KPIs — You and your agency should agree on what success looks like. Whether that's website traffic, leads, conversions, or brand awareness, everything needs to be measurable from the start.

What you shouldn't expect yet: Significant results. This phase is essential groundwork. If an agency promises you big wins in week two, that's actually a red flag, not a green one.

Month 2

Month Two: Building and Testing (Days 31–60)

With the groundwork in place, month two is where things start to take shape. Strategy is signed off, and execution begins.

This is an exciting phase, but it's also one where patience is important. Early campaigns and content rarely perform at their peak straight away, and they're not supposed to. This period is about testing, learning, and iterating.

What this typically looks like:

  • Strategy sign-off — You'll review and approve the marketing strategy before anything goes live. This is your chance to ask questions, raise concerns, and ensure everything aligns with your business vision.
  • First campaigns launch — Whether it's paid ads, email marketing, SEO content, or social media, the first pieces of work start going live.
  • Early data starts coming in — You'll begin to see initial performance numbers. Don't be alarmed if early figures are modest; this is normal. The data at this stage is valuable because it tells your agency what to optimise.
  • Regular check-ins — You should be hearing from your agency regularly, not just when you reach out. Proactive communication is a hallmark of a great agency.

What you shouldn't expect yet: Dramatic ROI. If a campaign launches and immediately delivers outstanding results, that's a bonus, not the benchmark. Month two is where momentum builds, not where you judge whether the partnership is working.

Month 3

Month Three: Optimising and Reporting (Days 61–90)

By month three, you have real data to work with. This is where a good agency shifts from "testing mode" into "optimisation mode" and where you start to see the shape of what's working.

What this typically looks like:

  • Data-led decisions — Campaigns, content, and strategies are being refined based on what the data is showing. What's working gets more resource. What isn't gets adjusted or cut.
  • Your first proper performance review — A structured report showing what's been done, what the results are, and what the plan is going forward. This should be clear, honest, and easy to understand, not a deck full of vanity metrics.
  • A roadmap for the next quarter — By now your agency should be presenting recommendations for where to go next, based on everything they've learned in the first 90 days.

What you should expect by now: Clear direction. You may not have full ROI yet, especially in areas like SEO, which typically takes 6–12 months to deliver strong, sustainable results, but you should have a clear picture of what's being done and why, and confidence in the direction of travel.

Green & Red Flags

What Good Looks Like at 90 Days

Not sure if your agency is delivering? Here are the green flags to look for at the end of your first 90 days:

✅ You understand exactly what work has been done and why
✅ You've had regular, proactive communication (no chasing required)
✅ KPIs were agreed upfront and are being tracked and reported clearly
✅ Early data is being used to inform decisions, not ignored
✅ You feel like a partner, not just a client
✅ There's a clear plan for the next quarter

And the red flags to watch for:

🚩 You're not sure what they've been working on
🚩 Reporting is unclear, infrequent, or full of jargon
🚩 Promises of overnight results were made  and haven't materialised
🚩 You're doing more chasing than they are
🚩 The strategy feels generic, not tailored to your business

The Bottom Line

The first 90 days with a marketing agency are about building the right foundations. The businesses that get the most from their agency partnerships are the ones who understand this and who invest in the relationship, not just the retainer.

Good marketing takes time. But with the right agency, the right strategy, and clear communication from the start, those 90 days will set you up for meaningful, measurable growth.
