Google Search suggestions are supposed to help you search faster, not clutter your space with a bunch of irrelevant search terms. While suggestions have worked well for Google Search and Google Image Search, they have proved a complete failure with Google Maps.
First of all, people already know what they’re looking for when they go to maps.google.com, especially if they’re trying to find a specific address. However, the suggestions just have to get in the way and display five totally irrelevant suggestions. I could imagine how suggestions would be useful when searching for a business like “pizza near chicago il”, but that’s one of the few times it’s only slightly useful.
So, Dear Google, please turn off Google Maps search suggestions. Thanks.
