The Google Map Pack is the boxed set of local business listings, shown with a map, that Google places above the organic results for a search with local intent. The box has traditionally shown 3 businesses, hence its other name, the 3-pack, and Google's own help page says local results are "mainly based on relevance, distance, and popularity."
What decides who appears in the pack
Relevance, distance and prominence are the three factors Google names for local results. Prominence, in Google's words, "means how well-known a business is," fed partly by how many websites link to the business and how many reviews it has. Complete, accurate profile information is what Google says makes the match.
Practitioners score the same ground more finely. The 47 local search experts Whitespark surveyed for its 2026 report, published November 2025, rated 187 factors, and the edition's headline change was review and behavioural signals gaining weight.
| Factor | Google's definition | What feeds it |
|---|---|---|
| Relevance | How well a profile matches the search | Complete, detailed business info |
| Distance | How far the business is from the searcher | The searcher's location, shared or inferred |
| Prominence | How well-known a business is | Links to the business, review count, ratings |
When the Map Pack matters, and what is changing
The Map Pack matters most when a searcher is ready to call, and its shape is moving. Sterling Sky's rank tracking, published June 2026, found AI-powered local packs on about 7% of the keywords it tracks - US mobile only - showing one or two businesses instead of three, and carrying no call buttons.
- AI local packs show 1 or 2 businesses instead of 3
- No call buttons on those packs
- Different businesses from the ones in the regular 3-pack
- 5,943 unique businesses surfaced against 18,330 in regular 3-packs, about 32%
Paid units are taking the rest. Across 2025, local pack ads went from 1% of the mobile reports Sterling Sky ran to nearly 22%. As of June 2026 that is one agency's keyword set, not an industry census, but the free slots are getting fewer.
