The phrase ‘Link Juice’ was coined by Internet Marketer and SEO consultant Greg Boser around 2007 and since then it has acquired a place of its own in the SEO world. It refers to how much benefit a link is passing on. Or, what is the pass through ratio of link equity. Further, it also refers to how much weight a page is perceived to contain. This weight it can share with other pages it links to, internally or externally.
Link juice flow
The amount of link juice available in each web page is indicated by its page rank. For example, a web page with page rank 6 has 6 times the amount of link juice available compared to a page with page rank 1. The quality of the link juice passed through a web page is depends on the number of outbound links. If we have two web pages with equal amount of web juice but one has 1 outbound link and another one has 6 outbound links. The quantity of link juice released to a third page from the single outbound link page, will be 6 times the quantity of the link juice passed from the web page with 6 outbound links.
As another example, the PR of a page is expressed some what exponentially, so a PR7 is not 7 times better then PR1, it is more likely to be 128 times better. The link juice is split up amongst the outbound links on the page. So if there are 100 other links on a PR7 page, it is more akin to the juice from a sole link on a PR1 page. Means links from a high ranking page is better, but the number of outbound links does dilute the juice passed.
Link juice optimization
When we try to control the flow of link juice in our website, this practice is called link juice optimization. It is the practice by which the page rank flows in a website.
It is also called page rank sculpting.
No Follow Tag
A link on a web page is followed during the indexing process of Search engines. Pages with many incoming links are ranked higher in searches than pages with few incoming links. If there are links on your blog that you don’t want search engines to find, use the No Follow tag to make them invisible in terms search indexing and ranking. A link using the ‘no-follow’ tag will look like this:
When a search engine sees a ‘no-follow’ tag in an HTML link, it will not follow it, nor assign link popularity to the destination page.
No follow tags are the method of link juice optimization.
These No Follow tags should used for links like:
- Login/ Signup/ Register
- Terms of Service
