Tracked live in Vortex IQ Nerve Centre. How to read it, why it matters, and how to act on it. **Card class:** [Sensitive](/nerve-centre/overview#card-classes-explained) • **Category:** [Brand Analytics & Search](/nerve-centre/connectors#connectors-by-type) ## At a glance > The split of your Amazon sales between organic (sales you did not pay an ad to win) and advertising-attributed (sales credited to Sponsored Products, Sponsored Brands, and Sponsored Display). It is shown as a share, usually a donut. A healthy brand earns most of its sales organically and uses ads to grow the edges. When the ad share climbs too high, you are renting your demand from Amazon, and a profitability and dependency risk is building underneath a top line that still looks fine. | | | | ----------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **What it shows** | The percentage of period sales attributed to advertising versus the percentage that came organically, displayed as a share. Ad-attributed sales are those Amazon credits to a Sponsored Products / Brands / Display click within the attribution window. | | **Why it matters** | A rising ad share means a growing slice of your revenue depends on paid placement. That is fine if the ads are profitable, but it erodes margin and creates dependency: pause the ads and that share of sales can disappear. | | **Attribution caveat** | Ad-attributed sales use Amazon's advertising attribution, which credits a sale to an ad click within a defined window. Some of those sales might have happened organically anyway, so "ad share" is the attributed share, not pure incrementality. | | **The dependency line** | When ad-attributed sales exceed roughly half of total sales, the alert fires. That is the point where the channel is more rented than owned, and a TACOS / margin review is overdue. | | **TACOS link** | This card is the share view of the same story TACOS tells in cost terms. See [Organic vs Ad sales](/nerve-centre/kpi-cards/amazon-seller/organic-vs-ad-sales-share) alongside your ad-spend and ACOS reads. | | **Brand vs non-brand** | A high ad share concentrated on your own brand terms is a warning sign: paying to win clicks you would likely win for free. Cross-check [Search Query Share (Brand)](/nerve-centre/kpi-cards/amazon-seller/search-query-share-brand). | | **Time window** | `30D` (trailing 30 days) | | **Alert trigger** | `ad share >50%`, driven by the brand-analytics detection layer. A majority-paid sales mix flags dependency and margin risk. | | **Roles** | owner, marketing, finance | ## Calculation Calculated automatically from your Amazon Seller Central and Amazon Advertising data. The card splits period sales into ad-attributed and organic and shows each as a share of the total. See the At a glance summary above and the worked example below. ## Worked example A UK supplements brand on amazon.co.uk. Period: trailing 30 days to 14 Mar 26. | Sales source | Sales (£) | Share | | ------------------------------------------------- | ------------ | ------------- | | Organic sales | £66,000 | 55% | | Ad-attributed sales (Sponsored Products + Brands) | £54,000 | 45% | | **Total sales** | **£120,000** | **100%** | | **Organic vs Ad Sales Share (this card)** | | **55% / 45%** | ```text theme={null} Ad-attributed share = 54,000 / 120,000 = 45% Organic share = 66,000 / 120,000 = 55% Alert threshold = ad share >50% -> not tripped (but close) A month earlier = ad share was 38% -> trending up fast ``` Five things to notice: 1. **45% is under the line, but the trend is the story.** Ad share sat at 38% a month ago and is now 45%. The absolute is below the 50% alert, but the trajectory says dependency is building. The trend matters more than the single reading. 2. **Rising ad share with flat total sales is the danger pattern.** If total sales held steady while ad share climbed from 38% to 45%, ad spend is buying sales that used to come for free, which means margin is quietly eroding behind a flat top line. 3. **Check how much is brand-term defence.** If a large chunk of the ad-attributed sales is on the brand's own search terms, the brand is paying to win clicks it would likely win organically. Read [Search Query Share (Brand)](/nerve-centre/kpi-cards/amazon-seller/search-query-share-brand) and [Top Branded Search Terms](/nerve-centre/kpi-cards/amazon-seller/top-branded-search-terms). 4. **Attribution is not incrementality.** The 45% is the attributed share, not proof that those sales would not have happened anyway. Treat it as a dependency signal to investigate, then test by pulling spend on a subset of ASINs to measure the true incremental lift. 5. **Pair the share with the cost.** This card shows the mix; the cost side (ad spend, ACOS, TACOS) tells you whether the paid share is profitable. A 45% ad share is fine if those campaigns beat your margin and a problem if they do not. At 45% the alert has not fired, but the fast climb toward the 50% line is exactly what this card is built to surface, so finance and marketing can review TACOS and incrementality before the channel tips into majority-paid. ## Sibling cards merchants should reference together Sales mix only makes sense next to cost and search context. Pair this card with: | Card | Why pair it with Organic vs Ad Sales Share | | ---------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------- | | [Total Revenue](/nerve-centre/kpi-cards/amazon-seller/total-revenue) | The denominator. A rising ad share against flat total revenue is the dependency-with-no-growth pattern. | | [Net Revenue (after fees + refunds)](/nerve-centre/kpi-cards/amazon-seller/net-revenue-after-fees-refunds) | The margin lens. Ad spend is not deducted from net here, so a high ad share warns that your marketing-adjusted margin is thinner than net suggests. | | [Search Query Share (Brand)](/nerve-centre/kpi-cards/amazon-seller/search-query-share-brand) | Reveals how much of the ad share is brand-term defence versus genuine new-customer acquisition. | | [Top Branded Search Terms](/nerve-centre/kpi-cards/amazon-seller/top-branded-search-terms) | Shows whether you are paying to appear on your own brand searches you would likely win organically. | | [Top Non-Branded Search Terms](/nerve-centre/kpi-cards/amazon-seller/top-non-branded-search-terms) | The healthy growth side: ad-driven discovery on non-brand terms is acquisition, not defence. | | [Channel Mix (Amazon vs DTC)](/nerve-centre/kpi-cards/amazon-seller/channel-mix-amazon-vs-dtc) | The bigger dependency picture: how much of total business sits on a channel where demand is increasingly paid-for. | ## Reconciling against Amazon Seller Central **Where to look in Seller Central and the Advertising console:** The two sources you reconcile against are: > Seller Central → Reports → **Business Reports** for total ordered product sales, and the **Amazon Advertising** console (Campaign Manager → Sponsored Products / Brands / Display reports) for advertising-attributed sales. The ad share is advertising-attributed sales divided by total sales. Brand Analytics (for Brand Registry sellers) adds the search-term and brand-share context that explains why the ad share is what it is. **Timing and reporting-lag table:** | Topic | Detail | | -------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | **Attribution window** | Advertising attributes a sale to an ad click within a defined window after the click, so an ad sale can be credited days after the click. This can shift the share for very recent days until attribution settles. | | **Reporting lag** | Advertising reports lag the underlying activity by up to a day or more. Total sales update closer to real time, so the freshest days can show an unstable share until ads catch up. | | **Sponsored Brands and Display** | Whether all sponsored ad types are included affects the ad share. Confirm the same set of ad products is counted on both sides. | | **Marketplace scope** | Both sales and ad reports are per marketplace. Confirm the same region on each side. | **Why our number may legitimately differ from a manual calc:** | Reason | Direction | Why | | ------------------------------ | -------------------- | ------------------------------------------------------------------------------------------------------------------- | | **Attribution window choice** | Either direction | Different attribution windows credit different amounts of ad sales. The share moves with the window definition. | | **Which ad types are counted** | Possible gap | Including or excluding Sponsored Brands and Display changes the numerator. Confirm the ad-product scope matches. | | **Reporting lag** | Recent days unstable | Ad attribution settles over days, so the freshest share is provisional and converges as reports finalise. | | **Total-sales basis** | Possible small gap | The denominator should be the same ordered-product-sales figure used elsewhere; a mismatched basis skews the share. | **Cross-connector reconciliation against other connectors the same seller may run:** | Card | Expected relationship | What causes legitimate divergence | | -------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | [`google-ads.paid_vs_organic`](/nerve-centre/kpi-cards/google-ads/total-revenue) | **Same concept, different channel.** Both measure how much of demand is paid. A brand over-reliant on paid on Amazon is often over-reliant on paid in Google too. | Channels have different organic dynamics (Amazon search rank vs Google SEO), so the paid shares are not expected to match, only to be read together for total paid dependency. | | [`ga4.organic_vs_paid`](/nerve-centre/kpi-cards/google-analytics/revenue-trend) | **DTC analogue.** GA4 shows the organic-versus-paid split for your own store traffic and revenue. | GA4 cannot see inside Amazon, so it measures DTC only; the two give a fuller cross-channel picture of paid dependency together. | ## Known limitations / merchant FAQs **Does a high ad share mean my ads are working?** Not necessarily. A high ad-attributed share means a large slice of sales is credited to ads, but attribution is not incrementality. Some of those sales might have happened organically anyway. A high share is a dependency signal to investigate, not proof of incremental success. Test by pulling spend on a subset of ASINs and measuring the real lift. **What is a healthy ad share?** There is no single right number, but most established brands keep ads as the minority of sales and grow organically. The alert fires above 50% because a majority-paid mix means you are renting more demand than you own. A growing share with flat total sales is the pattern to worry about most. **Why is a high ad share on my own brand terms a problem?** Because you are paying for clicks you would likely win for free. Defensive brand-term advertising has a place (blocking competitors), but if a large part of your ad-attributed sales is on your own brand searches, you may be paying Amazon for organic demand. Read [Search Query Share (Brand)](/nerve-centre/kpi-cards/amazon-seller/search-query-share-brand). **How does this relate to ACOS and TACOS?** This card is the share view; ACOS and TACOS are the cost view. ACOS is ad spend over ad sales; TACOS is ad spend over total sales. A rising ad share usually means a rising TACOS, which is the margin warning. Read them together: the share tells you the dependency, the cost tells you the profitability. **Why is the freshest day's share unstable?** Advertising attributes sales to clicks within a window, and ad reports lag by up to a day or more, while total sales update sooner. So the most recent days show a provisional share that settles as attribution finalises. Read the trailing 30-day view for a stable read. *** ### Tracked live in Vortex IQ Nerve Centre *Organic vs Ad Sales Share* is one of hundreds of KPI pulses Vortex IQ tracks across Amazon Seller Central and 70+ other ecommerce connectors.
