The term snack pack refers to the three local listings shown in a Google organic search result that relates to local goods and services. So a search including a location keyword, or a search for goods or a service that is typically local in nature will show a map and three business who have a business within the map area.
For example, search for simply ‘plumbers’ – you get a ‘snack pack’. Click the ‘More places’ link to view all location based results for your chosen keyword and the location you are in, up to 100.
If you reside in Portsmouth for example, and search for “Plumbers Winchester”, your snack pack and local listing results will be for Winchester, bot Portsmouth. However using a location keyword plus a service in one location, won’t always return the same results as doing the same search (i.e. “Plumbers Winchester”) in a different location, though the results will usually be similar.
