HOW DO SEARCH ENGINES MAKE MONEY?
Search engines make money in several ways, including the following:
- Pay-per-click ads. Advertisers or third-party advertising networks place ads on SERPs and on the content itself. The more views or clicks a search-related keyword gets, the more advertisers pay to have their advertisements associated with it.
- User data. Search engines also make money from the user data that they collect. Examples include search history and location data. This data is used to create a digital profile for a given searcher, which search engine providers can use to serve targeted ads to that user.
- Contextual ads Search engines also capitalize on serving up contextual ads that are directly related to the user’s current search. If a search engine includes a shopping feature on the platform, it might display contextual ads for products related to the user’s search in the sidebar of a website where advertisements are displayed. For example, if the online store sells books, an ad may appear in the corner of the page for reading glasses.
- Donations. Some search engines are designed help nonprofits solicit donations.
- Affiliate links. Some engines include affiliate links, where the search engine has a partnership in which the partner pays the search engine when a user clicks the partner’s link.
How do search engines personalize results?
Search engines personalize results based on digital searcher profiles created from user data. User data is collected from the application or device a user accesses the search engine with. User data collected includes search history, search date and time, location information, audio data, user ID, device diagnostic data, contact lists, purchase history etc.
Cookies are used to track browsing history and other data. They are small text files sent from the websites a user visits to their web browser. Search engines use cookies to track user preferences and personalize results and ads. They are able to remember settings, such as passwords, language preferences, content filters, how many results per page and session information.
Using private browsing settings or incognito browsing protects users from tracking but only at the device level. Search history and other information accumulated during search is not saved and is deleted after the search session. However, internet service providers, employers and the domain owners of the websites visited are able to track digital information left behind during a search.
