Search Query Share (Brand), Amazon Seller Central

Search Query Share (Brand) for Amazon Seller Central. Tracked live in Vortex IQ Nerve Centre. How to read it, why it matters, and how to act on it.

Metrics type: Supporting Metrics • Category: Brand Analytics & Search

At a glance

Your share of the action on the search queries that matter to your brand. Using Amazon Brand Analytics search-query data, it measures how much of the clicks and conversions on a given query your ASINs capture versus everyone else competing for that query. A high and stable share means you own your space; a falling share means a competitor is taking it, usually before the revenue impact shows up in sales. This is a brand-defence early-warning gauge.

What it measures	Your brand’s share of the clicks and/or purchases on a defined set of search queries, drawn from Amazon Brand Analytics (Search Query Performance / Search Catalogue Performance reports).
Why “share”	Absolute search volume rises and falls with the market. Share normalises for that: it tells you whether you are winning or losing the query relative to competitors, regardless of whether the category is up or down overall.
Brand vs category queries	This card focuses on brand-relevant queries (your branded terms plus the core non-branded terms you compete on). Losing share on your own branded terms is especially serious, it means someone is intercepting your buyers.
Requires Brand Registry	Brand Analytics is gated behind Amazon Brand Registry. Sellers without Brand Registry will not have this data; for them, Return Reason Clusters by ASIN and the search-term cards built on universally available data are the alternatives.
What a drop means	A competitor outranking you, a new entrant winning the query, your listing losing relevance or conversion, lost Buy Box on the ASIN that ranks for the query, or aggressive competitor advertising on your terms.
Leading indicator	Share shifts on a query before the revenue from that query fully moves, so it warns earlier than the sales line.
Time window	90D (the selected period)
Alert trigger	drop >5pp WoW, a fall of more than five percentage points week on week
Roles	owner, marketing

Calculation

Calculated automatically from your Amazon Seller Central data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.

Worked example

A brand-registered coffee-equipment seller tracking share on their core branded and category queries. Figures are illustrative.

Query	Your share, prior week	Your share, this week	Movement	Read
”[your brand] grinder” (branded)	71%	58%	-13pp	alert: a competitor is bidding on your brand
”burr coffee grinder” (category)	22%	20%	-2pp	normal variation
”espresso tamper” (category)	9%	14%	+5pp	a new listing is gaining traction
”[your brand] filters” (branded)	64%	63%	-1pp	stable, healthy

Branded-term defence:  share on "[your brand] grinder" fell 13pp WoW  →  past the 5pp alert.
                       Losing your OWN branded query is the most urgent kind of share loss:
                       buyers searching for you are landing on a competitor instead.
Category offence:      "espresso tamper" share rose 5pp  →  a winning listing worth doubling down on.

Four things to notice:

1. Losing share on your own brand name is the five-alarm signal. The 13pp drop on “[your brand] grinder” means people searching specifically for you are buying something else. The usual cause is a competitor advertising on your branded term, or your hero ASIN losing the Buy Box so a third-party offer wins the click. Defend branded terms first. Cross-check Top Branded Search Terms.
2. Category-term share is offence, branded-term share is defence. The +5pp on “espresso tamper” is growth on a contested category query, a win to reinforce with content and ads. The branded losses are defence: protecting demand you already earned.
3. Share moves before revenue does. A query you are losing today feeds the sales decline you will see next month. That lead time is the whole point, it lets you respond while you still can, not after the revenue has gone.
4. Small category moves are noise; branded moves rarely are. The -2pp on “burr coffee grinder” is within normal weekly variation for a contested category term. The same-sized move on a branded term would matter far more, because branded share should be high and stable by default.

Sibling cards merchants should reference together

Share is the gauge. These show the terms, the rankings, and the paid pressure behind it:

Card	Why pair it with Search Query Share (Brand)
Top Branded Search Terms	The branded queries you should be defending. A share drop here points to which term lost ground.
Top Non-Branded Search Terms	The category battlegrounds where you play offence to grow share.
ASIN Conversion Rank by Query	Tells you whether a share loss is a ranking problem or a conversion problem on the query.
Organic vs Ad Sales Share	If you are defending share with ads, this shows how much of the win is paid for.
Buy-Box Win Rate (top-50 ASINs)	Lost Buy Box on the ASIN that ranks for a query can cause a query-share drop.
Brand Registry Coverage	This card depends on Brand Registry. Coverage tells you which of your brands actually feed this data.

Reconciling against Amazon Seller Central

Where to look in Seller Central:

The closest Amazon-native views are:

Brand Analytics → Search Query Performance (per-ASIN and per-brand query metrics) and Search Catalogue Performance, both under the Brands menu for Brand-Registry-enrolled accounts.

These Brand Analytics reports show impressions, clicks, cart-adds, and purchases per query, along with your share of each. This card distils that into a single share gauge per query and watches it for week-on-week moves so you do not have to re-pull the report manually.

Timing, settlement, and reporting-lag table:

Topic	Detail
Brand Analytics lag	Brand Analytics reports are published on Amazon’s own cadence (often weekly, with a lag of several days). This card is therefore not real-time; “this week” reflects the most recent published Brand Analytics period.
Brand Registry requirement	Without Brand Registry there is no Search Query Performance data and this card cannot populate. Enrolling unlocks it going forward, not retroactively.
Query aggregation	Amazon aggregates the long tail of search queries. Very low-volume queries may be grouped or omitted, so share is most reliable on meaningful-volume terms.
Click vs purchase share	Share can be measured on clicks or on purchases; the two can diverge (you win the click but lose the sale). Be clear which lens you are reading.

Why our number may legitimately differ from Seller Central:

Reason	Direction	Why
Report cadence	Ours lags	Brand Analytics publishes periodically with a lag; the card reflects the latest published period, not live search activity.
Click vs purchase basis	Definition difference	If you compare a click-share figure to a purchase-share figure, they will not match. Confirm the basis.
Query grouping	Long-tail differences	Amazon groups low-volume queries; share on niche terms may differ from a hand-pulled subset.
Brand Registry scope	Missing brands	Only brands enrolled in Brand Registry feed this. An unenrolled brand shows no share.

Cross-connector reconciliation against other connectors the same seller may run:

Card	Expected relationship	What causes legitimate divergence
amazon.asin_conversion_rank_by_query	Two reads on the same query. Share is how much you capture; conversion rank is how well your ASIN converts that query relative to peers.	You can hold high share on a query while converting below the category leader, or vice versa.
google_search_console query data	Different search engines. Amazon search behaviour and Google search behaviour for the same brand are separate.	A brand can dominate Amazon search yet have weak Google visibility, and the reverse. They do not reconcile.

Known limitations / merchant FAQs

Do I need Brand Registry for this card? Yes. The underlying Search Query Performance data is part of Amazon Brand Analytics, which is gated behind Brand Registry. Without it the card cannot populate. Brand Registry Coverage shows which of your brands are enrolled.

Why is losing share on my own brand name so serious? Because those shoppers are searching specifically for you and buying something else. It almost always means a competitor is advertising on your branded term, or your hero ASIN lost the Buy Box so a third-party offer wins the click. It is the most direct form of demand interception there is, defend branded terms before anything else.

Why share instead of just search volume or sales? Volume rises and falls with the whole market, which hides whether you are winning or losing. Share strips that out: a falling share on a flat-volume query still means a competitor is taking your customers. Share is the competitive read; volume is the market read.

Why isn’t this real-time? Brand Analytics reports publish on Amazon’s own schedule with a lag of several days, so the freshest data here reflects the most recent published period, not live searches. Use it as a weekly competitive review, not a same-day dashboard.

Click share and purchase share disagree, why? You can win the click but lose the sale (price, reviews, Buy Box) or vice versa. A high click share with low purchase share points to a conversion problem on the listing; check ASIN Conversion Rank by Query.

A category-term share dropped a couple of points, should I worry? Usually not. Small moves on contested category queries are normal weekly noise. The same-sized move on a branded term is far more meaningful, because branded share should sit high and stable. Calibrate your concern to the type of query.
