Content-category search market share
also called market_share_categoryShare by content category
Definition
Your own CTR-modeled share of the tracked search demand within one page-side content category, such as product pages or help content.
How it's calculated
One grouped read on the customer-category dataset: the page-side content category as the dimension and the category share measure as the metric, with brand and intent applied as re-weighting parameters rather than ordinary row filters. The semantic layer defines that measure as the category's summed daily demand share over the period's category total, scaled to a percentage on the same basis as the rest of the family. It is YOUR share within the category, that dataset carries no per-competitor columns at all, so no rival column can be selected beside it. Reconciled against the product's own category tab on a live tenant (32.6866 read against a displayed 32.69%, and 0.0344 against 0.03%).
Scope, grain and dimensions
- Grain
- One content category × segment × period × medium.
- Dimensions
- category · intent · brand · rank_bucket
- Required filters
- segment_id · selected_period · source_medium
- Aggregation
- Not summable across categories, categories do not partition the tracked demand and each row is a share against its own slice.
- Metric type
- share · % of the tracked search demand within the category

How to read it
A read on where your content estate is strong, not a competitive standing. Because that dataset has no rival columns, the correct sentence is "we hold X% of the tracked demand in this category", never "we lead this category".
Caveats, freshness and failure modes
This is your own share within the category, not share of voice against tracked rivals, the underlying dataset carries no competitor columns.
Categories are PAGE-side content categories, not keyword groupings; a keyword-side category read is a different question.
Category is a filter and a group-by only on this dataset: the category column on the keyword-and-page dataset is not selectable, so a category breakdown routes here and joins clicks from a separate read.
The click leg switches source with the filter, a brand or intent filter routes it to the keyword-and-page combined table, an unfiltered read to the page combined table. That mirrors the product, but the two are different populations.
Clicks come back null on a tracked segment: the whole-domain click read would overstate it and the segment's own filters cannot be reconstructed on that side. The share stays segment-scoped and correct.
The union of the share rows and the click rows keeps one-sided rows, so a category can show share with no clicks, or clicks with near-zero share.

Common failure modes
- Presenting a category share as a competitive position.
- Requesting a category group-by together with competitor columns, which the verbs refuse with a steer rather than returning a plausible wrong number.
