[1]Search engine privacy is a subset of internet privacy that deals with user data being collected by search engines. Both types of privacy fall under the umbrella of information privacy. Privacy concerns regarding search engines can take many forms, such as the ability for search engines to log individual search queries, browsing history, IP addresses, and cookies of users, and conducting user profiling in general. The collection of personally identifiable information (PII) of users by search engines is referred to as tracking.[1]
This is controversial because search engines often claim to collect a user's data in order to better tailor results to that specific user and to provide the user with a better searching experience. However, search engines can also abuse and compromise its users' privacy by selling their data to advertisers for profit.[1] In the absence of regulations, users must decide what is more important to their search engine experience: relevance and speed of results or their privacy, and choose a search engine accordingly.[2]
The legal framework in the United States for protecting user privacy is not very solid.[3] The most popular search engines collect personal information, but other search engines that are focused on privacy have cropped up recently. There have been several well publicized breaches of search engine user privacy that occurred with companies like AOL and Yahoo. For individuals interested in preserving their privacy, there are options available to them, such as using software like Tor which makes the user's location and personal information anonymous[4] or using a privacy focused search engine.
