Total search share, paid leg
also called Paid presence input
Definition
The segment-scoped search impression share that total search share uses as its paid input.
How it's calculated
A single-row read of the averaged search impression share measure on the keyword-grain impression-share dataset, filtered to the segment, the date range and your canonical site URL. It is the same measure the impression-share tool returns, read here without a breakdown.
Scope, grain and dimensions
- Grain
- One number per segment and date range.
- Dimensions
- segment
- Required filters
- segment_id · date_range
- Aggregation
- An unweighted average across keyword-day rows, read as one row for the segment.
- Metric type
- share · share of available auction impressions (stored 0 to 1)

How to read it
Auction coverage used as a stand-in for paid presence on the results page. It measures eligibility and exposure inside the ad auction, which is a narrower thing than occupying the page, part of why the combined total is labelled an estimate.
Caveats, freshness and failure modes
Impression share is auction coverage, not page occupancy; using it as a presence probability is the approximation the combined total is labelled for.
Stored as a fraction between 0 and 1 while the organic leg is stored 0 to 100.
Unweighted average across keyword-day rows.
Impression share lost to budget is not measured on this dataset. The budget-lost measures exist only on a campaign-grain dataset that no tool reads, so a budget-capped account looks smaller here without the reason being visible.
It ships beside the organic leg under a camel-case payload key the shared format contract cannot classify, so it renders as a bare 0 to 1 number with no percent sign.
- Freshness
- ~1 day behind, Ads reporting settles overnight; same-day spend is provisional.
Common failure modes
- Treating auction impression share as share of the results page.
- Comparing it directly to the organic leg without normalising.
