There are various SEO techniques available now a days and it will definitely help you in boosting and ranking keywords of a website.
Backlinks
A backlink is a link from one website to another. Backlinks are used as a ranking signal by search engines like Google because when one website links to another, it indicates that the material is valuable.
Working of Backlinks
Backlinks function similarly to peer reviews for online pages. It is a sign that a book offers useful information if it is quoted several times by many relevant and authoritative sources. Similarly, a large number of relevant and authoritative links leading to a web page indicates that it offers important material.
In Google's opinion, the more relevant connections from authoritative websites you have, the more valuable your website is. However, a method in which you can obtain such valuable links on your own would be ineffective.
Types of Backlinks
1. Do follow
The most popular and valuable sort of backlink for SEO is the dofollow link. When you use a dofollow link on your website, you're informing Google that the link is natural (i.e., the target website didn't pay for it) and that you're vouching for the accuracy of the material on the other end. Dofollow merely informs Google and other search engines that "the material on the other end of this link is significant and should be acknowledged."
2. No follow
Backlinks with nofollow attribute are less popular. They're also worth less. They're used to warn search engines that a particular link should be ignored.“‘Nofollow' provides a mechanism for webmasters to tell search engines ‘Don't follow links on this page' or ‘Don't follow this specific link,'” according to Google's official definition.The HTML syntax for these links is similar to that for dofollow links, with the exception of the "rel=nofollow" tag.
