In terms of SEO, the “noindex” tag is a directive you can give to search engine crawlers, telling them not to include a specific page in their index. When a page has a noindex tag, it means that the page will not appear in search engine results, even though the search engine crawlers may visit and read the page. Essentially, you’re instructing search engines that you don’t want this particular page to be listed in their search results.
Here’s how it is generally implemented in the HTML of a webpage:
<meta name="robots" content="noindex">
Or for specific search engines, you might see:
<meta name="googlebot" content="noindex">

It’s important to use the noindex tag carefully. Accidentally applying a noindex tag to important pages can result in those pages disappearing from search engine results, which could substantially decrease your organic traffic. Always double-check your work and monitor your search engine presence after implementing noindex tags.
