You can conduct anonymous Google searches with StartPage.com to avoid having your data tracked and linked back to you. See the excerpt below from Michael Bazzell’s book.
Anonymous search
“Start Page (startpage.com) If you want to take advantage of Google’s search abilities but insist on hiding yourself from their intrusive monitoring techniques, you can use Start Page. Start Page’s anonymous search scans Google for you. When you submit a search, Start Page submits the query to Google and returns the results to you. All Google sees is a large amount of searches coming from Start Page’s servers. They cannot associate any traffic to you or track your searches. Start Page discards all personally identifiable information and does not use cookies. It immediately discards IP addresses and does not keep a record of any searches performed.” from “Hiding from the Internet: Eliminating Personal Online Information” by Michael Bazzell
