Noopener is a meta tag that is used in the HTML code of a webpage to prevent search engines from opening a link in a new tab or window. When a user clicks on a link that has the noopener tag, the link will open in the same tab or window, rather than a new one.

The noopener tag is useful for preventing users from accidentally opening multiple tabs or windows when clicking on links. It can also be used to prevent users from leaving a website and going to a different website through a link.

Here’s an example of how the noopener tag is used:

<meta name=”robots” content=”noopener”>
In this example, the meta tag is placed in the head section of the HTML code, and it instructs search engines not to open links in a new tab or window. The content attribute is set to “noopener”, which is the value that tells search engines not to open the link in a new tab or window.

It’s important to note that the noopener tag only applies to search engines, and it does not affect how users interact with links. Users can still choose to open links in a new tab or window if they want to.

It’s also worth noting that the noopener tag is not a foolproof solution. Some search engines may still open links in a new tab or window, even if the noopener tag is present. Therefore, it’s important to use the noopener tag in conjunction with other SEO techniques to ensure that your website is optimized for search engines.
