A robots.txt file notifies search engine bots which URLs on the site they may visit. This is mostly intended to prevent requests from exhausting the site. It is not a strategy for blocking a web page from Google.

What is the purpose of a robots.txt file?

A robots.txt file is used largely to regulate spam visitors to the site and, according to the file type, to pull a file off Google:

A robots.txt file can be used to control scanning traffic for website pages (HTML, PDF, or even other non-media files that Google can read), to avoid crawling irrelevant or similar web pages, or to prevent crawling irrelevant or identical website pages.

• If a robots.txt file restricts the web page, its URL will still display in search results; however, the description will be missing. Image, video, and PDF files, as well as other non-HTML media, will be prohibited.
• Use a robots.txt file to manage crawl activity and avoid pictures, multimedia, and audio files from displaying in Google search results, use a robots.txt file. This does not affect other pages or individuals connecting to the picture, video, or music file.
• Suppose you believe that the loss will not adversely harm pages loaded without image resources. In that case, you can utilize a robots.txt file to block resource files, including irrelevant images, scripts, or styling files. However, if the lack of these resources makes it difficult for Google’s visitors to comprehend the page, do not block them. On the other hand, Google will not be able to evaluate the pages that rely on such specific resources.

Limits of a robots.txt file

Before creating or modifying a robots.txt file, individuals should be aware of its limitations. Depending on the aims and scenario, one may want to investigate additional ways to prevent their URLs from being found on the internet.

Some search engines may not support robots.txt directives.

The directives in robots.txt files cannot compel searchers to visit the site; it is up to the browser to follow them. While Googlebot and other trustworthy online tools will adhere to the guidelines in a robots.txt file, other searchers may not. As a result, if you wish to safeguard information from web crawlers, you need to use alternative blocking measures, like password-protecting confidential files on the server.

The syntax is interpreted differently by different crawlers.

Although reputable web searchers adhere to the directions in a robots.txt file, every browser may interpret the guidelines differently. Because certain web crawlers may not comprehend some commands, one should be familiar with the right syntax for addressing them.
