The X-Robots-Tag is a meta tag that can be added to the header of a webpage to provide instructions to search engine crawlers and other web robots. It can be used to prevent indexing of certain pages or content, or to specify how frequently a page should be crawled and cached.
Here is an example of how to use the X-Robots-Tag to prevent a page from being indexed:
<meta name="robots" content="noindex" >
This tells search engine crawlers not to index the page. Other values for the "content" attribute can be used to specify different instructions, such as "noarchive" to prevent caching of the page, or "nofollow" to prevent search engines from following links on the page.
It's important to note that the X-Robots-Tag is just one tool for controlling how search engines interact with your website. Other techniques, such as using a robots.txt file or implementing canonical URLs, may also be necessary depending on your specific needs.
