Overview and trends

Today, by marketplace

The top of Overview is Today beside Yesterday — sales, royalties, ad spend and profit, with the products that sold — updating as syncs land. The page goes on in this order: This month & last month, Sales trend, Ads efficiency, Reviews, Marketplaces today and, on the US store, the Royalty group.

Today is the one number that never gets a comparison. The day is not finished, there is no hour-of-sale data to compare against, and a percentage on a half-day would be a guess dressed as a fact.

The trend

The sales trend chart shows units, royalty, net and spend over your chosen period, per marketplace. Two overlays can sit behind it: the previous period and the same period last year.

Both compare like with like. A rolling period — last 7 days, last 30 — is clipped to whole days and matched against the same number of whole days before it, so eleven days are never judged against thirty-one. A calendar period keeps its calendar meaning on purpose: last month compares April against March even though one has thirty days and the other thirty-one, because the thing being compared is the month, not a count of days.

A cliff has a date; a slide is a season. A number that fell off on one day usually matches something you did — a price change, a paused campaign. A number that slid all month is usually seasonality. The two lead to different investigations, and the daily curve is how you tell them apart.

Ads efficiency

Spend, ad sales, ACoS — each judged against what your products can actually afford. The dashboard knows every product's royalty, so its verdicts are against break-even, not against a generic "good ACoS" folklore number.

Break-even is a band rather than a line, and the interface says so. It can be computed two ways — from revenue and from units — and when a period mixes prices or marketplaces the two disagree. Where they disagree the verdict is unknown, not an average of the two. There is also a small noise floor: a result within a few percent of break-even is reported as at break-even rather than as a win or a loss, because at that distance the difference is rounding.

The royalty group tracker

US store only. Amazon's US store pays Merch royalties in groups — Creator, Plus and Premium — a monthly multiplier of ×1, ×2 and ×2.16 driven by the share of your unit sales that arrive through non-organic traffic.

The window is the part people get wrong. The group effective on the 1st of a month is set by the trailing 60 days ending on the 18th of the previous month. Never calendar months, and the group only ever changes on the 1st.

The tracker shows three windows at once:

The third matters more than it looks. The windows overlap, so late in a window a target like "719 more ad-driven sales" can be a fantasy with two days left while the window with a month of runway is wide open. The tracker also shows the gap to Plus and Premium — how many extra ad-driven sales above your current pace each would take.

The ad-driven percentage here is a floor. The extension sees Amazon Ads attribution only. Amazon also counts off-Amazon traffic it attributes to you, so your real figure may be higher — never lower. Eligibility needs at least 10 units a month over the window.

Sale notifications

When a sync finds new sales, the extension shows a notification: the product, the marketplace, and the royalty.

Two rules shape it, and both exist to stop it lying to you:

• The marketplace is always named, because this app has no concept of a "home" market. A sale in Germany is a sale in Germany, not an unlabelled number you assume is American.
• The royalty appears only when every sale in the batch settles in one currency. Summing dollars and euros into a single figure is exactly the kind of confident wrong number this product refuses to show, so where the batch is mixed the figure is left out rather than invented.

If your laptop was closed and sales piled up, the notice says "since you were last here" rather than presenting a weekend's accumulation as if it had just happened.
