A plain-language explanation
Google is a technology company and the name of an internet search engine around which there is an extensive ecosystem of advertising, maps, analytics, cloud services and tools for companies.
Where it helps in practice
For a business, Google spans search, ads, maps, browser and data products, so performance in one service does not describe total brand visibility.
The decision before implementation
Separate organic, paid, local and product discovery first, then assign an owner and source of truth to each channel.
How to verify the result
Review search presence, visit quality and dependence on one service rather than reporting one blended number.
