Sign In for Personalized Results
You may be aware that Google lets you create your own personal Google Account. This is typically used to log into various Google services, such as Google Calendar and Gmail.
What you probably didn’t know is that if you log into your Google Account while searching, Google will display more personalized search results, based on your location and previous searches.
For example, when you’re logged into your Google Account, Google will include nearby businesses in select search results. If you’re not logged in, Google doesn’t know where you are, and can’t provide these localized results.
As another example, Google will track your past queries, and when you start to enter a new query, suggest one of your previous queries in the drop-down box beneath the Search box as you type. This way you don’t have to re-enter searches that you do frequently; Google knows what you’ve looked for and figures you might be looking for that thing again.
So there’s real benefit to creating and using a Google Account when searching. The downside is that Google is watching every move you make, which some people might find disconcerting. If this bothers you, don’t log into your Google Account while searching.
