The NoIndex tag is used by website owners and developers to prevent a web page from appearing in the search results, and to prevent the search engines from crawling and indexing the page.
The NoIndex tag is an important factor in search engine optimization (SEO), as it allows website owners to control and optimize the way that search engines crawl and index the content on their website. The NoIndex tag is also an important tool for search engines, as it helps the search engines to provide the most relevant and useful results to the users who search for a query, and to avoid showing irrelevant or duplicate content in the search results.
To use a NoIndex tag, website owners and developers can include the NoIndex tag element in the HTML code of the web page that they want to exclude from the search results. The NoIndex tag should be included in the head section of the page, and it should include the value “noindex” in the content attribute of the tag.
