Differentiate between Dofollow and Nofollow

"Dofollow" and "nofollow" are terms used in the context of hyperlinks on webpages, especially in relation to search engine optimization (SEO). They indicate whether search engines should follow the link and consider it when determining the target webpage's ranking in search results.

1. Dofollow Links:
   - Dofollow links are standard hyperlinks that search engines can follow to discover new webpages and pass authority (link juice) from one webpage to another.
   - When a webpage links to another webpage with a dofollow link, it essentially endorses that webpage, contributing to its search engine ranking.
   - Dofollow links are the default type of link, meaning if a link is not explicitly marked as "nofollow," it is considered dofollow.

2. Nofollow Links:
   - Nofollow links are hyperlinks that include the rel="nofollow" attribute in the HTML code. This attribute instructs search engines not to follow the link or consider it when calculating search engine rankings.
   - Nofollow links were introduced by search engines to combat spam and prevent the manipulation of search engine rankings through excessive link building or paid links.
   - While nofollow links don't pass authority or influence rankings directly, they can still be valuable for driving traffic and user engagement.
   - Common scenarios where nofollow links are used include user-generated content (e.g., comments on blogs), sponsored content, and links that a website owner doesn't want to endorse for various reasons.

In summary, the main difference between dofollow and nofollow links lies in how search engines treat them for ranking purposes. Dofollow links pass authority and contribute to search engine rankings, while nofollow links do not pass authority and are not considered for rankings, although they can still be beneficial for other purposes like referral traffic and user engagement.
