Dofollow vs Nofollow Links: An Ultimate Guide

When it comes to Search Engine Optimisation, words such as dofollow and nofollow are re-occuring. These words can be quite confusing to people who aren’t familiar with HTML or SEO jargon. Nofollow is an HTML attribute for the anchor tag while we use the anchor tag to embed hyperlinks in the HTML code.

To understand nofollow and dofollow, you have to understand the basic operations of search engines. Search engines such as Bing and Google have search algorithms that scan web pages in websites on the internet. The search algorithms are referred to as bots, spiders, or crawlers, and the act of scanning is referred to as crawling. After the algorithms have scanned the pages, the scanned pages are processed and stored in the databases of Bing or Google for their search engine results. The process of storing web pages is referred to as indexing.

The saved pages are the indexed pages. Indexed pages will be displayed on the search results referred to as Search Engine Related Pages (SERPS). When the spiders or bots are crawling web pages, they pass through all hyperlinks in a page. Typically, they are supposed to follow the hyperlinks. The web developer may wish to include links that spiders cannot follow. Otherwise, all other hyperlinks are referred to as dofollow links.

Nofollow hyperlinks

They are introduced in the source code to reduce search engine spam. They are generated within HTML code. Developers use nofollow to prevent the website from credit passing other sites. Nofollow gives a link to an endorsed document such as user-generated content, comments or paid links. It’s used by Google to direct the search spiders not to follow the links and does not contribute to the ranking of a site.

The syntax for creating nofollow hyperlinks

The developer has to define the nofollow links in the anchor tag. Usually, nofollow tags are created using the following HTML code.

<a href=“www.medium.com” rel=“nofollow”>Best blog</a>

Situations where nofollow hyperlinks are used

Google has policies that guide the usage of nofollow links.

  • Comments. There is no need for search engines to crawl through comments posted by visitors. Also, using nofollow for comments will discourage hackers and spammers from attacking your site.
  • Non-indexed pages. Sometimes a website has pages that you do not want to be displayed publicly. Thus, they should not be in the search engine results.
  • Forums. Forums have many posts that are irrelevant and might be considered as spam.
  • Paid links. Search engines such as Google discourage paid links to prevent them from influencing search results.
  • Corrupted content. The developer should use nofollow links if the hyperlink leads to a website that is not trusted by the search engine.

Hyperlinks and SEO boost

Every hyperlink in a web page gives a website SEO boost. However, the type of links, dofollow or nofollow, determine whether the website gets the boost or not.

Dofollow links allow spiders of a search engine to crawl a link and thus, they get a higher ranking. High-ranked sites are considered reputable.

Nofollow does not allow search engines to crawl the hyperlinks and thus, the links do not lead to a higher ranking. However, they are essential when reducing spam-indexing. It is important to note that nofollow links are visible on the website and the user can click on them to navigate the web page that was linked.
