The First 90 Days with an Amazon Agency: What Should Happen

Key takeaways: The first two weeks are access, audit and plan. Wasted spend and listing fixes show in the numbers within two to four weeks. Rank and TACoS take six to twelve weeks because they depend on sales history building. If an agency promises a transformed account by day 30, or has not changed anything by day 30, both are warning signs.

Weeks one and two: access, audit, plan

Nothing useful happens until the agency can see the account. The first week is spent getting user access to Seller Central and the advertising console, the cost data needed to build profit per ASIN, brand assets, and a clear statement of the objective and the KPI it will be judged on. The full list of what a good agency asks for, and why, is in A5 · What we need from you before work starts; an agency that asks for everything at once and waits usually loses a week that did not need losing. The audits can start on the advertising data while the rest arrives.

The audit itself covers the advertising account, the listings, the creative, the catalog health, inventory and unit economics, and it produces two things: a scorecard of where the account stands and a 30/60/90-day plan that starts where the biggest gap is. That plan is the document the next three months are measured against. If you do not have it in writing by the end of week two, ask for it.

The timeline

Weeks two to four: the fast fixes

The first changes are the ones with certain payoff and quick readouts. In advertising, that means negatives on search terms that have spent without selling, budget moved from campaigns that overlap to the ones that convert, and campaign structure tidied so each campaign has one job. On the listing side, it means suppressed or stranded ASINs restored, missing attributes filled, and any policy problems in the copy corrected. These changes show in the weekly report inside two weeks: wasted spend falls, ACoS moves toward target, and sessions recover on any listing that was suppressed.

What you should not see in this window is a total rebuild of the campaign structure on day three. Rebuilding destroys the sales history attached to existing campaigns and resets everything the audit measured. A good agency changes what is broken and leaves what works.

Weeks four to eight: the page and the rank

Once the account is clean, the work moves to the things that take longer to read. Main image tests through Manage Your Experiments run for several weeks. Title and bullet rewrites need 48 hours to index and two to three weeks of traffic to judge on conversion. Exact-match campaigns on the core keywords start pushing organic rank, which usually takes four to six weeks to move. Click-through and conversion changes from creative work typically show in two to four weeks; that is why they start now and not in week ten.

Weeks eight to twelve: taper and scale

By now the agency should know which ASINs have the margin and the page to scale and which need more work. Where rank has been won, paid support is tapered in steps and the organic share of orders should be rising. Where margin and stock allow, budget is added to the campaigns that convert. TACoS on the mature range should be moving in the right direction, though it rarely reaches the end target inside 90 days. A stock check comes before every scaling decision, because a new agency that scales you into a stock-out has undone its own work.

Day 90: what a fair review looks like

The review at day 90 is against the plan written in week two, not against a vague sense of whether things feel better. The primary KPI, the metric the whole engagement was set up to move, is the first line. If it is on track, the engagement moves into its steady weekly cycle and the next quarter is planned. If it is not, the question is why: a page problem the tests have not solved yet, a price position, a stock gap, or a market change. An honest agency will say which, and revise the plan. What you should not accept is a new primary KPI chosen because the old one did not move.

What you should have by day 90

• A written plan, and a report against it every week since week two.
• A change log you can inspect for every edit made in the account.
• Profit per ASIN, built from your cost data, in the monthly reports.
• Clear ASIN groups with different targets: launches, growth, mature, fix.
• A test program running, with results recorded.
• A restock and seasonal calendar for the next two quarters.

If most of those are missing, the problem is not that Amazon takes time. It is the engagement.
