What kind of figure
Observed Seen directly, such as a search result, a map listing or an ad.
How it’s calculated
Each month we run the searches from a point in every neighbourhood of the area (ABS SA2), on a mobile, and read the first page of Google results. Services chosen from anywhere in the state (plan management, support coordination) are searched with the state’s capital city too (“ndis plan manager adelaide”), and each search is shown on its own. Neighbourhoods count by their number of residents (2021 census), so a busy suburb weighs more than an industrial one.
Where Google shows an AI Overview, we read the sites it cites and count each provider’s share of the citations.
Results are matched to providers by their website or Google listing. Directories, platforms and public sites are counted separately and never as a provider.
Keep in mind
- Google shows AI Overviews for some searches only, and sometimes without citations; those count as an AI Overview but add no citations.
