A no-index tag is an instruction used in website coding to tell search engines not to include a specific page in their search results. When a page is tagged with no-index, search engines will still be able to crawl and read the content, but they won’t add the page to their index, preventing it from appearing in search results.
This tag is commonly used for pages that site owners don’t want publicly accessible through search engines, such as private landing pages, thank-you pages, or duplicate content. It can also be useful during the development phase of a website or for content that is not intended to drive organic traffic.
By using the no-index tag, businesses and webmasters maintain control over what content is visible to the public via search engines, helping to prevent certain pages from being ranked. Although these pages will still be accessible through direct links, they won’t affect the site’s SEO performance or clutter search engine listings with less relevant content.
