Webuild your own websiteWhen building our own website, we must have heard about doing external links, but doing external links also involves a nofollow option.
External links that use the nofollow attribute have no effect on website SEO optimization even if they are done, because it prevents the transfer of weight. So how do we check whether a link is nofollow?
What is a Nofollow link?
A nofollow link refers to a link with the rel=„nofollow“ tag in the hyperlink code.
Nofollow means telling the search engine "do not follow this link." Simply put, if you go to a website to post a link, and the link has the nofollow attribute, then you will not get a website vote through this website, and it will not increase the SEO weight of your website.

How to determine if a link has nofollow?
Simple example,What kind of link is called a nofollow link：
Link format without nofollow will pass search weight
<a href="https://blog.naibabiji.com/">奶爸建站笔记</a>
Link format with nofollow, does not pass search weight
<a href="https://blog.naibabiji.com/" rel="nofollow">奶爸建站笔记</a>
How to check if a link is nofollow?
The simplest method is to use the inspect function of the Chrome browser, as demonstrated in the image below.
- Right-click on the link you want to check, then click Inspect;
- Check if the link's rel attribute contains nofollow, if it contains it, it means it has nofollow.
- 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 most SEO materials online indicate that links with nofollow will not help SEO, because it tells the search engine not to follow.
However, if you can leave your link in a place where others can see it on a large website, it is also beneficial to your website, at least for exposure.
More information can be found by yourself.
Usually, you can add nofollow to some irrelevant links on your website, such as ICP filing number, advertising links, etc.
