Nofollow links can directly help you with your SEO. As you just saw, experiments and industry studies have discovered that nofollow links can lead to higher rankings on Google. Everyone tells you that nofollow links are useless for SEO. They don't increase your search rankings, so you don't need to waste time or money on them.
To conclude, nofollow links are still valuable for SEO, and will be valuable in the near future. Essentially, you should implement them as part of your link building strategy. That is, even if you're not actively contacting for nofollow links, you shouldn't reject contextual links marked with “rel%3DNofollow”. It's been 14 years since the nofollow link became part of the SEO industry and nothing really changed until yesterday.
For SEO professionals who want to carefully and easily keep track of untracked links, there are many downloadable extensions available for Chrome and Firefox that automatically highlight no-follow or no-follow links on the pages you visit. Make a reasonable effort to ensure that all paid or advertising links on your site use the rel%3d nofollow, rel%3d sponsored, or rel%3d ugc attribute to prevent the links from being followed by a crawler and could affect search rankings. While the website's socks category remains indexed, the nofollow link attribute prevents the search engine from crawling the filtered website, which can have thousands of nearly identical variations. The people who create Google's secret algorithm know that website owners are trying to use nofollow links to protect their own SEO by not helping the SEO of other websites.
In addition to the examples I shared in the previous section, there are several strong reasons why untracked links from high-authority sites can continue to play a crucial role in increasing your search rankings. For example, the nofollow link attribute can prevent search engines from following links to filtered product pages. Wikipedia also got complicated, as people tried to add their own sites as references to hundreds of Wikipedia pages, all in the name of the coveted link juice. Nofollow links, also known as rel%3d nofollow, is a link attribute used by websites to tell search engines, especially Google, not to pass the juice of links from one website to another.
A dofollow link is any normal link that gives the referenced page an additional link. However, this approach is not infallible and never was. If someone links to those filtered pages from a different website, search engines can follow those links and crawl the filtered product pages. The only difference between a dofollow link and a nofollow link is that the nofollow link tells Google not to associate the referring website with the referring website.
Links that don't have the value of the nofollow attribute are simply “followed” links, and the difference is that they don't aim to stop search engines from crawling your landing page. This immediately makes you think about the benefits of having excellent links outside of SEO; the main one is relevant referral traffic from who could become your next customer or customer. The key is to build your brand; don't think about which links are good for SEO, but what links are good for your business, your brand, and what links can help you establish yourself as an industry authority.
