The signals that matter for ranking in the map pack are weighted differently than for ranking in localized organic results.

This statement is true. While there's significant overlap in ranking factors, the Google Maps algorithm (which determines Map Pack rankings) places a heavier emphasis on proximity, prominence, and relevance to the searcher's location. Localized organic results, on the other hand, consider a broader range of traditional SEO factors like website authority, content quality, and backlinks, in addition to local signals. Therefore, a business might rank well in one but not necessarily the other, indicating different weighting of signals.
