First 90 Days With an Amazon Agency: Week-by-Week Timeline

Week 1: Onboarding and account access

Everything starts here, and it starts fast. A good agency will send you a structured onboarding form within 24 hours of contract signature. That form covers your goals, margin targets, competitive set, seasonal calendar, and any brand guidelines that govern copy or imagery.

The technical side is just as urgent. You will need to grant access to:

• Seller Central (or Vendor Central): the agency needs a dedicated user with the right permission level, typically Admin or specific role-based access depending on your comfort
• Amazon Advertising console: either direct access or an agency-linked account through the Amazon Ads portal
• Brand Registry: if the agency will manage A+ Content, Brand Store, or Vine, they need Brand Registry access
• Product cost sheet: landed cost per unit (including freight, duties, and FBA fees) so the agency can calculate true profitability, not just ACOS

Some agencies also ask for access to your DTC analytics (Shopify, GA4) and any existing keyword research. Hand this over. It gives the team a baseline for cross-channel attribution and prevents redundant work. If your account health dashboard has open policy violations or warnings, flag them now so they get triaged immediately.

By the end of week one, your agency should have a shared Slack channel or project management board, a named point of contact, and a scheduled kickoff call. If none of those exist by Friday, ask questions.

The audit: weeks 1-2

The audit is the single most important deliverable in the first 90 days. It should cover at least six areas:

1. Account health and compliance: open cases, policy warnings, listing suppressions, and intellectual property issues
2. Listing quality: title structure, bullet points, backend keywords, indexing gaps, image count and quality, A+ Content presence
3. Advertising structure: campaign taxonomy, match type distribution, wasted spend (search term reports going back 60-90 days), and ACOS vs TACoS trends
4. Competitive positioning: pricing relative to top three competitors, review velocity, share of voice on priority keywords
5. Inventory and fulfillment: FBA restock limits, stranded inventory, IPI score trajectory
6. Brand Registry utilization: whether you are using Brand Store, Sponsored Brands, Posts, or Vine at all

The output is a prioritized roadmap. Not a 60-page PDF that sits in a Google Drive. A ranked list of actions with estimated impact, effort, and timeline. At Hyperzon, the audit feeds directly into the 90-day sprint plan the team reviews with you on a live call. You can request a free audit before you even sign to see what this looks like.

What are quick wins, really?

Quick wins get talked about a lot. Here is what they actually look like in weeks 2-3:

• Pricing corrections: fixing suppressed or misaligned pricing that is costing you the Buy Box
• Coupon and promotion activation: turning on Subscribe and Save, coupons, or promotional badges where margin allows
• Negative keyword harvesting: pulling 60+ days of search term data and adding obvious waste terms as negatives across campaigns
• Backend keyword fixes: filling empty fields, removing duplicate terms already in the title, and adding Spanish or alternate-language keywords if relevant
• Stranded inventory resolution: relisting stranded ASINs that are sitting in FBA warehouses costing storage fees

None of these require creative assets from you. They are operational fixes the agency handles with existing data. The combined effect can be noticeable within 7-14 days: lower wasted ad spend, improved Buy Box ownership, and a small bump in conversion rate.

Weeks 3-5: Advertising restructuring

This is where the heavy lifting begins. A competent agency does not just tweak bids on your existing campaigns. They rebuild the architecture.

The typical approach follows a clear logic: segment campaigns by objective (ranking, efficiency, defense), by match type, and by product grouping. A single auto campaign running all your SKUs is a red flag your agency should fix immediately. The restructured setup usually includes Sponsored Products (exact, phrase, broad, and auto campaigns separated), Sponsored Brands (headline and video), and Sponsored Display for retargeting. If your budget supports it and you meet the threshold, DSP campaigns for upper-funnel awareness come later.

During this phase, the agency should share a clear ACOS target framework with you. That means knowing which campaigns are meant to be profitable, which are meant to drive ranking (and will run at a higher ACOS on purpose), and which are defensive. If every campaign has the same target, the strategy lacks depth.

Expect some short-term ACOS volatility during restructuring. New campaigns need data. Old campaigns get paused or consolidated. This is normal and should be explained to you before it happens, not after.

Listing work: weeks 3-6

Listing optimization runs in parallel with ad restructuring, but it takes longer because it depends on you.

What the agency handles

Keyword-driven title and bullet point rewrites, A+ Content design and copywriting, image sequencing recommendations, and Brand Store build or refresh. The agency should base every change on search term data and competitor analysis, not gut feel.

What you need to provide

High-resolution product images (the agency will brief you on exactly what shots are needed), brand guidelines, ingredient or specification details, any compliance claims that require documentation, and approval on copy. This is the phase where brands cause the most delays. If you take two weeks to approve a bullet point rewrite, the timeline shifts. Appoint one person on your side with final sign-off authority and commit to 48-hour turnaround on approvals.

Listing changes compound with advertising improvements. Better images and copy increase your conversion rate, which lowers your effective cost per acquisition, which lets the agency bid more aggressively on high-value keywords. Skipping or delaying listing work undercuts everything the ad team is building. For brands that need a deeper look at this, our conversion rate optimization guide breaks down which listing elements to test first.

Reporting cadence: what to expect and when

A weekly snapshot. A monthly deep dive. That is the baseline.

The weekly snapshot should land in your inbox (or Slack) every Monday or Tuesday. It covers revenue, ad spend, ACOS, TACoS, sessions, and conversion rate. No commentary needed beyond callouts on significant changes. The monthly report is different: it is a strategic document. It should include what was done, what moved, what did not, and what is planned next. A live call to walk through it is non-negotiable.

By week 4, you should also see a custom dashboard. Most agencies use tools like Amazon Seller Central reporting alongside third-party platforms (Helium 10, Pacvue, Intentwise) to build consolidated views. Ask for access to the dashboard so you can check numbers between reports.

One thing to watch for: if your agency only reports on ad metrics (impressions, clicks, ACOS) and never ties them back to total revenue, organic rank movement, or profitability, the reporting is incomplete. TACoS (total advertising cost of sale) is a better health indicator than ACOS alone because it shows whether organic sales are growing relative to ad spend.

Realistic results: day 30, 60, and 90

Day 30

You should see wasted ad spend reduced, initial listing fixes live, and a clear roadmap in place. Revenue may or may not have moved significantly. If the account was badly mismanaged before, you might see a 10-15% improvement in ad efficiency. If the account was already decent, the gains are smaller but the foundation is tighter. The real value at day 30 is clarity: you know exactly where you stand and where you are headed.

Day 60

Ad campaigns have enough data for meaningful optimization. Listing changes are live and indexed. You should see conversion rate improvements, organic keyword movement on your top 10-20 targets, and a TACoS trend moving in the right direction. Brands with existing sales history often see 15-25% revenue growth by this point, assuming inventory is not a constraint. This is also when A+ Content and Brand Store updates start influencing branded search behavior.

Day 90

Compounding kicks in. Better listings drive higher conversion rates, which improve organic rank, which reduces ad dependency. A well-run first 90 days typically delivers 20-40% revenue improvement for brands doing $30k+ per month on Amazon. For a real-world example, one home fragrance brand saw 440% revenue growth within five months of restructuring its Amazon presence. Results vary by category, competition, and budget, but directionally, you should see meaningful movement across revenue, profitability, and organic share of voice by day 90.

If you are not seeing measurable progress by day 60, raise it on your next call. A strong agency will adjust the plan. A weak one will ask for more time without explaining why.

What separates a productive first 90 days from a wasted one

Speed of information transfer. Every day the agency waits for your cost data, your image files, or your approval on copy is a day the timeline slides. The brands that get the most out of the first 90 days treat the engagement like a partnership, not a handoff. They assign an internal owner, respond within 48 hours, and show up to calls prepared.

The agency's job is to bring operator-level expertise and execution speed. Your job is to provide the raw materials and decisions that only you can make. When both sides deliver, 90 days is enough time to fundamentally change the trajectory of your Amazon business.
