What is the link juice?

In the Interlinks -> Juice menu one of the statistics provided by the plugin is the link juice. In this answer will be described how this value is calculated in Interlinks Manager, how to customize the algorithm used to calculate this value and the meaning of this value.

How the link juice is calculated?

When the link juice of an internal link is calculated the following information is retrieved:

SEO POWER = The SEO Power of the post
TOTAL LINKS = The total number of links of the post
LINKS BEFORE = The number of internal links that precede the link being considered
PENALITY PER POSITION = The value of the "Penality per Position" option

Then this formula is applied to calculate the link juice:

LINK JUICE = SEO POWER / TOTAL LINKS - ( SEO POWER / TOTAL LINKS / 100 * PENALITY PER POSITION * LINKS BEFORE )

As you can see from this formula the link juice calculated by this plugin is based on the SEO power of your internal links and does not consider links to your website URLs that come from external websites. For this reason, it should be used only to have an idea of how much strength you are assigning to specific URLs of your website with your internal links strategy. You should not assume that the URLs of your website that receives more link juice from your internal links are considered by the search engines as the most important URLs of your website because search engines consider many other factors.

Inspect the link juice received by the URLs

You can have access to the link juice received by the URLs with this procedure:

  • Visit the Interlink -> Juice menu
  • Click the Generate Data button
  • Browse the generated values from in the Interlink -> Juice menu or download the data in CSV format with the Download button included in the Export CSV section

Please note that the received by the URLs is a cumulative value that comes from the sum of all the single link juice values calculated with the formula explained in the previous section.

Inspect the link juice generated by the single links

You can have access to the link juice generated by the single links with this procedure:

  • Visit the Interlink -> Juice menu
  • Click the Generate Data button
  • Open the modal window that allows you to view the internal links that contribute to generate the link juice receive by the URL or download the same data in CSV format

Customize the calculation of the link juice

The parameters used to calculate the link juice can be modified in the Juice tab of the plugin options and the following fields are available.

OptionExplanation
SEO Power The “SEO Power” is the base value used to calculate the flow of “Link Juice” and this option determines the default “SEO Power” value of a post. You can override this value for specific posts in the “Interlinks Options” meta box.
Penalty per Position (%)With multiple links in an article, the algorithm that calculates the “Link Juice” passed by each link removes a percentage of the passed “Link Juice” based on the position of a link compared to the other links.
Remove Link to Anchor Select “Yes” to automatically remove links to anchors from every URL used to calculate the link juice. With this option enabled “http://example.com” and “http://example.com#myanchor” will both contribute to generate link juice only for a single URL, that is “http://example.com”.
Remove URL Parameters Select “Yes” to automatically remove the URL parameters from every URL used to calculate the link juice. With this option enabled “http://example.com” and “http://example.com?param=1” will both contribute to generate link juice only for a single URL, that is “http://example.com”. Please note that this option should not be enabled if your website is using URL parameters to actually identify specific pages. (for example with pretty permalinks not enabled)
