What is Noindex tag?

Noindex tag - a directive used in HTML code to instruct search engines not to index a specific page or section of a website. This means that the page or section will not show up in search engine results pages (SERPs) and will not be included in search rankings.

The use of noindex tags can be beneficial for webmasters who want to prevent certain pages from being indexed, such as duplicate content, temporary pages, or private information. Additionally, it can help prevent penalties from search engines for having low-quality content or spammy links on your site.

However, it's important to note that using noindex tags should be done with caution and only when necessary. Overusing them may result in significant drops in traffic and visibility for your website.
