← Back to Amazon Search Term Impression Share Benchmarks: Why One Target Doesn’t Fit Every Campaign
Quick answer
Amazon campaign impression share is a diagnostic metric that becomes misleading when compressed into one global target. A branded campaign can capture a far higher share than a broad non-branded campaign, and an auto campaign rarely follows the same pattern as an exact-match manual campaign. Reviewing impression share separately for each campaign shows whether low visibility is driven by budget, bid, or relevance, and it keeps a global average from hiding waste and missed opportunity.
One number can feel simple, but it often directs attention to the wrong place. Splitting impression share by campaign gives you a clearer picture of where spend is working and where a campaign-level adjustment is needed.
Why a single impression share target hides campaign differences
A global target usually averages together branded terms, non-branded terms, auto campaigns, and manual match types that behave very differently. A branded campaign may consistently capture most of its available impressions because the query is specific and competition is lower. A broad non-branded campaign may show a lower impression share even when it is profitable, because it competes in a much larger auction pool.
When those campaigns are flattened into one number, the average can look acceptable while individual campaigns drift off target. A campaign-level view makes it easier to see whether a low impression share is a budget problem, a bid problem, or simply a relevance problem.
Building a campaign-level breakdown
Start by exporting search term and campaign performance data at daily or weekly granularity. Group by campaign first, then by match type or targeting group. For each campaign, review impression share together with spend, sales, ROAS, and wasted spend. The Amazon Ads Dashboard by Todoza can bring those KPIs into one view instead of forcing you to compare separate reports.
- Branded campaigns: expect a higher impression share; focus on maintaining strong coverage and protecting margin.
- Manual exact campaigns: use impression share to spot queries where a small bid increase may improve visibility profitably.
- Auto and broad campaigns: treat impression share as a discovery signal, not a hard target; use it to find search terms worth moving into manual campaigns.
When this matters
This level of detail is most useful when an account contains a mix of campaign types, product margins, or audience segments. A single global target can lead sellers to over-invest in high-impression branded terms while neglecting profitable long-tail terms that need a different bidding strategy. It also matters when you are scaling spend quickly and need to know which campaigns have room to grow without simply raising bids across the board.
