Link juice is a colloquial term in the Search Engine Optimization world that refers to the Internal or External links from the other website or webpage to our website or web page.
Link juice is one of the main SEO factors because it helps the website to gain better Page Rank.
We can gain links to our website by many ways through direct or indirect.
Direct link building strategy includes Directory submission, Document sharing, Press release submissions, Social media promotions and Guest blogging or commenting etc. While Indirect link building strategy refers to Infographics or presenting best content.
The links that you receive from both Direct and Indirect method is known as the link juice. The quality of the link juice varies depending upon the authority of the website or webpage that links to your site.
How do the link juice works?
For example, if there are two sites, Google and Yahoo. Google has one link and Yahoo has no links so Google will rank high due to the link juice it receives.
Link juice passing happens in both directions. Web site linking to Google also links to various sites. But websites linking to Yahoo only links in Yahoo. In this case link juice percentage received from Yahoo is more than that of Google. This may increase the Yahoo rankings.
Page Rank Sculpting:
Page Rank Sculpting is used to preserve the loss of link juice in the case of Nofollow attribute. PageRank sculpting was conceivable when a webmaster added a nofollow attribute to one of the external links, which implied that the link juice would not exchange to the page that is nofollowed but rather would be appropriated to alternate links.
