Nofollow links represent backlinks that will not pass link juice to the linked site, and search engines do not index it.
What is a nofollow link?
Nofollow links are backlinks created by third-party websites (most of the time) using a rel="nofollow" HTML tag to tell search engines to ignore that link when the crawling is done.
Update: as of September 2019, Google seems to have changed the way it interprets “follow” and “nofollow” links. It has been suggested that Google may start taking into account “nofollow” links in some cases, regardless of the instructions coming from the website where the hyperlink is.
How to check if a backlink is nofollow?
Usually, a backlink helps websites rank higher and be indexed faster because it passes PageRank and trustworthiness. But using a nofollow tag, a website actually communicates to spiders and search engines do not consider the like, so it won't pass link juice, PageRank, nor will have any impact as a backlink for the search engines.
If a website had multiple backlinks, but no signs of better ranking, a double check to see if the backlinks are nofollow is always more than welcomed. Here is a step-by-step guide to identifying a nofollow link:
- Go to the web page that has the hyperlink
- Right-click on the page and select Inspect (or View Page source)
- Identify the link in the HTML code and check if there is a <a href "https://yoursite.com" rel=nofollow">
