How to check if an external link is nofollow?

Webuild your own websitemust have heard about the need to create external links, but creating external links involves an option called nofollow. External links that use the nofollow attribute, even if created, have little effect on website SEO optimization because they block the transfer of link equity. So, how do we check if a link is nofollow?

What is a Nofollow link?

A Nofollow link refers to a hyperlink in the code that has a rel="nofollow" tag. Nofollow means telling search engines "do not follow this link."

1. Right-click on the link you want to check, then click Inspect;
2. Check if the link's rel attribute contains nofollow, if it contains it, it means it has nofollow.
3. In the demonstration above, the Lightning Blog link does not have nofollow, while the ICP filing link has nofollow.

In the demonstration, the noopener noreferrer attribute added to the link is a solution to a vulnerability of the _blank new window opening attribute. The general idea is that if an external site link opens in a new window, not adding noopener noreferrer may pose a phishing risk. Specific details can be found online. By default, when you set a new window to open in a WordPress post, this attribute is automatically added.

Do Nofollow links affect SEO?

Almost all SEO materials online indicate that links with Nofollow added will not help SEO because they already tell search engines not to follow them. However, if you can leave your link in a visible place on a large website, it can be beneficial for your site indirectly, at least for exposure. More information can be researched independently. Typically, you can add nofollow to some irrelevant links on your website, such as ICP filing numbers, advertisement links, etc.
