It affects crawl strategy, international visibility, privacy positioning, and where content realistically has a chance to surface. This page breaks down which engines maintain their own indexes, which depend on third-party sources like Bing or Google, and which operate as aggregators or meta engines. It’s intended as a working reference for evaluating visibility beyond the dominant players, especially as AI-driven search products reshape how results are sourced and presented. _see also, [big list of directories](https://www.searchengineworld.com/list-of-a-few-directories)_ Here’s a list of the top search engines on the web, each with a brief description and source of their index: - [![](https://www.searchengineworld.com/gfx/favicons/google.com.png)Google](https://www.google.com/) _Own Index:_ Google utilizes its proprietary web crawlers and indexing algorithms to maintain its search index. – URL: [https://www.google.com](https://www.google.com/) - [![](https://www.searchengineworld.com/gfx/favicons/bing.png)Bing](https://www.bing.com/) _Own Index:_ Microsoft’s Bing employs its own web crawlers and indexing systems. – URL: [https://www.bing.com](https://www.bing.com/) - [![](https://www.searchengineworld.com/gfx/favicons/baidu.com.png)Baidu](https://www.baidu.com/) _Own Index:_ Baidu operates its own web crawlers and indexing, primarily serving the Chinese market. – URL: [https://www.baidu.com](https://www.baidu.com/) - [![](https://www.searchengineworld.com/gfx/favicons/yandex.com.png)Yandex](https://www.yandex.com/) _Own Index:_ Yandex maintains its own search index, catering mainly to Russian-speaking users. – URL: [https://www.yandex.com](https://www.yandex.com/) - [![](https://www.searchengineworld.com/gfx/favicons/wolframalpha.com.png)WolframAlpha](https://www.wolframalpha.com/) _Own Index:_ WolframAlpha uses its own computational knowledge engine to provide answers. – URL: [https://www.wolframalpha.com](https://www.wolframalpha.com/) - [![](https://www.searchengineworld.com/gfx/favicons/mojeek.com.png)Mojeek](https://www.mojeek.com/) _Own Index:_ Mojeek operates its own web crawlers and maintains an independent index. – URL: [https://www.mojeek.com](https://www.mojeek.com/) - [![](https://www.searchengineworld.com/gfx/favicons/www.sogou.com.png)Sogou](https://www.sogou.com/) _Own Index:_ Sogou maintains its own search index, serving primarily Chinese users. – URL: [https://www.sogou.com](https://www.sogou.com/) - [![](https://www.searchengineworld.com/gfx/favicons/www.so.com.png)360 Search (So.com/Haosou)](https://www.so.com/) _Own Index:_ Operated by Qihoo 360, 360 Search maintains its own web crawler and index and serves primarily the Chinese market. – URL: [https://www.so.com](https://www.so.com/) - [![](https://www.searchengineworld.com/gfx/favicons/m.sm.cn.png)Shenma Search](https://m.sm.cn/) _Own Index:_ Alibaba’s mobile-focused search engine maintains its own search infrastructure and primarily serves users in China. – URL: [https://m.sm.cn](https://m.sm.cn/) - [![](https://www.searchengineworld.com/gfx/favicons/www.seznam.cz.png)Seznam](https://www.seznam.cz/) _Own Index:_ Seznam operates its own search engine, primarily for the Czech market. – URL: [https://www.seznam.cz](https://www.seznam.cz/) - [![](https://www.searchengineworld.com/gfx/favicons/www.naver.com.png)Naver](https://www.naver.com/) _Own Index:_ Naver maintains its own search index, serving primarily South Korea. – URL: [https://www.naver.com](https://www.naver.com/) - [![](https://www.searchengineworld.com/gfx/favicons/search.daum.net.png)Daum Search](https://search.daum.net/) _Own Index:_ Kakao’s search portal maintains localized search services for South Korea and is the country’s other notable domestic search engine alongside Naver. – URL: [https://search.daum.net](https://search.daum.net/) - [![](https://www.searchengineworld.com/gfx/favicons/coccoc.com.png)Coccoc Search](https://coccoc.com/search) _Own Index:_ Vietnamese search engine with its own crawler and localized index, supplemented by outside sources where needed. – URL: [https://coccoc.com/search](https://coccoc.com/search) - [![](https://www.searchengineworld.com/gfx/favicons/boardreader.com.png)Boardreader](https://boardreader.com/) _Own Index:_ Boardreader specializes in indexing forums and message boards. – URL: [https://boardreader.com](https://boardreader.com/) - [![](https://www.searchengineworld.com/gfx/favicons/search.brave.com.png)Brave Search](https://search.brave.com/) _Own Index:_ Brave Search operates its own independent search index. – URL: [https://search.brave.com](https://search.brave.com/) - [![](https://www.searchengineworld.com/gfx/favicons/openverse.org.png)Openverse](https://openverse.org/) _Index Source:_ [Common Crawl](https://commoncrawl.org/) Openverse is a tool that allows openly licensed and public domain works to be discovered and used by everyone.
