# Make a list of fruitless links in search engines There are several ways to create a list of fruitless links in search engines： ## 1. Use the site: search operator By specifying a subdomain or directory that does not exist： ``` site:example.com/nonexistent-directory ``` ## 2. Use a combination of nonexistent search terms ``` "THIS PHRASE DOES NOT EXIST ON ANY web PAGE" AND "ANOTHER FICTITIOUS PHRASE" ``` ## 3. Filter using specific file types ``` filetype: xyz content that does not exist ``` ## 4. Use negative operators to exclude all possibilities ``` word -word ``` ## 5. Use a very specific date range ``` Find content before: 1900 after: 2000 ``` Please note： -The search engine may display "No result found" instead of a blank page -Some search engines may still display relevant results instead of completely empty results -Different search engines may have different operators and grammars This method is usually used to test search engine behavior or used in demonstrations.
