What is Robots.txt?
The robots.txt file is a text file located in a website’s root directory that instructs search engine crawlers which pages or sections of the site should not be crawled or indexed. It acts as a guide for search engines, telling them which areas of the website are off-limits. This file is handy for preventing indexing pages that are not meant to be publicly visible, such as admin pages, duplicate content, or specific scripts.
The robots.txt file can also be used to control search engines’ crawl rate, preventing server overloads during high-traffic periods. However, it’s important to use robots.txt cautiously, as incorrectly configuring the file can inadvertently block important pages from being indexed, negatively impacting SEO. It’s also worth noting that the robots.txt file is a suggestion to search engines, not a command, meaning some crawlers may choose to ignore it. Regularly reviewing and updating the robots.txt file is essential for maintaining optimal site visibility and crawlability.
