DoFollow Links: Search engine bot will follow these links and certain value will be given to them, based on the quality of your blog. Attribute rel=”dofollow” is used when we interlink the articles on the same blog.

NoFollow Links: If you add nofollow link to any word or link, it means you are telling the Search Engine Bot, not to follow those links. Attribute rel=”nofollow” is mostly used when we add a link to any low quality or affiliate links.
