Q: How often does the option to combine a robots.txt disallow with a robots.txt noindex statement make folders or URLs appear in SERPs?
B) Less than ones without noindex
Correct Answer is C) Never.
Search engine spiders use robots.txt files to determine which pages and folders to crawl and index. The combination of a robots.txt disallow with a robots.txt noindex statement can be used to prevent certain folders or URLs from appearing in SERPs (Search Engine Results Pages). This is a useful tool for website owners who want to keep certain parts of their website hidden from search engines and users alike.
However, it is important to note that combining a robots.txt disallow with a robots.txt noindex statement does not guarantee that the folder or URL will never appear in SERPs; rather, it just makes it less likely for them to appear in SERPs as search engine spiders will ignore them when crawling the website. Thus, it is important for website owners to understand how often this option may make folders or URLs appear in SERPs before implementing it on their websites.
