NoFollow is a term commonly used in the context of search engine optimization (SEO) and refers to a value that can be assigned to the rel attribute of an HTML link to instruct search engines that the hyperlink should not influence the ranking of the link’s target in the search engine’s index. It is intended to reduce the effectiveness of certain types of internet spam, thereby improving the quality of search engine results and preventing spamdexing from occurring. The NoFollow tag tells search engines to ignore a link, which means that when a website links to another site with a NoFollow tag, it does not pass along what is known as “link juice.” Link juice is a term used in SEO to describe the value passed from one site to another. This is significant because the number and quality of inbound links to a website are a factor in determining the ranking of that site in search engine results. By using the NoFollow attribute, website owners and content creators can link to other websites without endorsing them in terms of search engine rankings.
