The First 90 Days with a Digital Marketing Agency: What to Expect

Signing with a digital marketing agency is a significant decision — and the first 90 days set the tone for the entire partnership. Whether you're investing in PPC management, Meta Ads, affiliate marketing, or Shopify development, understanding what happens during those critical first three months helps you evaluate progress, set realistic expectations, and get the most from your investment.

Too many businesses sign with an agency expecting instant results, then feel disappointed when month one is spent on audits and strategy rather than scaling. That frustration is almost always a communication gap — not a performance gap. This guide walks you through exactly what should happen, week by week, so you can hold your agency accountable to the right milestones at the right times.

Weeks 1–2: Onboarding and Discovery

The first fortnight is all about knowledge transfer. A good agency will invest heavily in understanding your business before touching a single campaign. Here's what should happen during onboarding:

The Kickoff Call

Your agency should schedule a structured kickoff meeting covering your business model, target audience, competitive landscape, historical performance, and short-term and long-term goals. This isn't a casual chat — it's a strategic discovery session that informs every decision for the next 90 days and beyond.

At Spires Digital, our kickoff calls typically run 60–90 minutes and cover everything from your customer acquisition costs and lifetime value to your seasonal patterns and margin structures. We need to understand your business as well as you do to make intelligent decisions with your budget.

Access and Account Setup

During the first week, expect to provide access to your Google Ads, Meta Ads Manager, Google Analytics (GA4), Google Search Console, Shopify admin (if applicable), and any affiliate network dashboards. A professional agency will use their own manager accounts whilst ensuring you retain full ownership of every asset.

If your agency doesn't ask for GA4 access on day one, that's a red flag. As we cover in our Google Ads management expectations guide, data access is the foundation of every meaningful optimisation.

Stakeholder Alignment

The agency should identify key stakeholders, establish communication channels, and agree on reporting cadence. Weekly check-ins during the first month are standard practice — these can shift to fortnightly or monthly once the relationship is established and performance is stable.

Month 1: Audit, Analysis, and Strategy

The first full month is diagnostic. Your agency should be auditing everything — your existing campaigns, tracking setup, website performance, and competitive positioning. This is where the real value starts compounding.

The Comprehensive Audit

A thorough audit covers every channel you're investing in:

• PPC audit: Account structure, keyword relevance, Quality Scores, bid strategies, negative keyword coverage, ad copy effectiveness, landing page alignment, and conversion tracking accuracy
• Meta Ads audit: Campaign objectives, audience targeting, creative performance, pixel configuration, attribution settings, and frequency management
• Affiliate audit: Programme terms, commission structures, publisher quality, attribution windows, and fraud detection measures
• Website audit: Page speed, mobile experience, conversion rate optimisation opportunities, and technical SEO foundations

This audit should result in a written document with prioritised recommendations — not a vague verbal summary. If your agency can't produce a structured audit report, they likely don't have a structured process.

Tracking and Measurement Setup

Before any campaign changes, your agency must verify (or fix) your conversion tracking. This includes GA4 event configuration, Google Ads conversion actions, Meta pixel events, and any server-side tracking requirements. Getting this right in month one prevents months of optimising against bad data.

Strategy Development

Based on the audit findings, your agency should present a 90-day strategy document covering:

• Quick wins: Immediate changes that can improve performance within weeks (pausing wasteful spend, fixing tracking gaps, adjusting bid strategies)
• Medium-term initiatives: Structural improvements that take 4–8 weeks to implement and measure (campaign restructuring, audience testing, creative overhaul)
• Long-term growth plays: Strategic investments that compound over 3–6 months (brand building, affiliate programme expansion, Shopify store optimisation)

What Results to Expect in Month 1

Honestly? Don't expect dramatic performance improvements in month one. The primary deliverables should be clarity, structure, and a data-informed plan. If your agency is promising 50% improvement in week three, they're either sandbagging the setup period or making promises they can't keep.

That said, quick wins from the audit — such as pausing irrelevant keywords or fixing broken conversion tracking — can sometimes deliver immediate savings or improved data quality.

Month 2: Implementation and Testing

Month two is where strategy becomes action. Your agency should be implementing the recommendations from the audit and running structured tests across channels.

Campaign Restructuring

If the audit identified structural issues — and it almost always does — month two is when campaigns get rebuilt properly. For PPC, this might mean restructuring ad groups around tighter keyword themes, implementing proper SKAG or STAG structures, or migrating to Performance Max where appropriate. For Meta Ads, it could involve consolidating fragmented campaigns, building proper funnel structures, or implementing Advantage+ campaigns.

Creative Testing

Good agencies run systematic creative tests rather than making gut-feel changes. In month two, expect to see A/B tests on ad copy, headlines, creative formats, and calls to action. Each test should have a clear hypothesis, controlled variables, and defined success criteria.

This is where the difference between hiring an agency versus managing ads yourself becomes most apparent. Systematic testing requires discipline, patience, and statistical literacy that most in-house teams struggle to maintain alongside other responsibilities.

Audience Development

Month two should include building and testing new audience segments. For PPC, this means refining keyword lists and testing new match types. For Meta Ads, it involves lookalike audience creation, interest-based testing, and custom audience development from your CRM data. For affiliate marketing, it means identifying and recruiting new publisher partners aligned with your target customer profile.

Reporting Cadence

By the end of month two, your reporting structure should be fully established. You should receive weekly performance snapshots and a comprehensive monthly report with analysis, insights, and recommendations. The monthly report should directly reference the 90-day strategy and track progress against agreed KPIs.

Month 3: Optimisation and Scaling

By month three, your agency should have enough data to make confident optimisation decisions. This is where performance should start improving measurably.

Data-Driven Optimisation

With two months of clean data under controlled conditions, your agency can now optimise with confidence. This includes adjusting bid strategies based on actual conversion data, reallocating budget from underperforming campaigns to proven winners, refining audience targeting based on conversion patterns, and scaling winning creative variations.

Cross-Channel Integration

If you're running multiple channels — and most serious businesses should be — month three is when cross-channel synergies should start emerging. Your PPC and Meta campaigns should be coordinated rather than siloed. Your affiliate programme should complement rather than cannibalise your paid media. Your Shopify store should be optimised for the traffic your campaigns are driving.

This integrated approach is central to how we work at Spires Digital. Operating from our offices in Guernsey and Lichfield, we manage all channels under one roof — which means your PPC manager and your Meta Ads strategist are literally sitting next to each other, sharing insights in real time.

The 90-Day Review

At the end of month three, your agency should present a comprehensive review covering:

• Performance vs baseline: How key metrics have changed since day one
• Strategy execution: What was planned, what was delivered, and any variances
• Key learnings: What the data has revealed about your audience, messaging, and channel effectiveness
• Next quarter plan: An updated strategy for months 4–6 based on three months of real data

Scaling Decisions

Month three is typically when scaling conversations begin. If the first 90 days have delivered positive unit economics, your agency should recommend controlled budget increases with clear projections. If results are mixed, they should present a diagnosis and revised approach — not excuses. And if results are genuinely poor despite a solid process, an honest agency will tell you so and help you understand why.

Red Flags During the First 90 Days

Watch for these warning signs that your agency engagement isn't on track:

• No audit or strategy document: If your agency skips the diagnostic phase and jumps straight to "optimising," they're guessing, not strategising
• Radio silence: If you're chasing your agency for updates rather than receiving proactive communication, their account management is understaffed
• No access to accounts: You should have full transparency into every platform at all times. No exceptions
• Vanity metrics in reports: If reports focus on impressions and clicks rather than conversions, revenue, and ROAS, your agency is hiding behind noise
• No testing framework: If changes are made without hypotheses or controlled conditions, results are luck rather than strategy

What Good Looks Like: Setting Realistic Expectations

A strong first 90 days with a digital marketing agency should deliver clarity on what's working and what isn't, a clean data foundation for future decision-making, early performance improvements from quick wins and structural fixes, a tested and validated strategy for scaling, and a relationship built on trust, transparency, and shared goals.
