Comparison of web search engines
From Wikipedia, the free encyclopedia
Web search engines are listed in tables below for comparison purposes. The first table lists the company behind the engine, volume and ad support and identifies the nature of the software being used as free software or proprietary software. The second and third table lists internet privacy aspects along with other technical parameters, such as whether the engine provides personalization (alternatively viewed as a filter bubble).
For the market share of the most popular search engines, see Most popular Internet search engines. For search proxies and multi-engine searches, see List of metasearch engines.
Defunct or acquired search engines are not listed here.
