The Interlinks Manager plugin allows you to assign a priority to each keyword with the Priority option of the AIL. This value determines the order used to apply the AIL.
More precisely, the following two rules are considered by the algorithm:
- The AIL with a high priority are applied before the AIL with a low priority.
- When two AIL have the same priority the order used to create the AIL in the back-end is used to determine the priority of the AIL. In other words, when two AIL have the same priority the first added AIL have higher priority than the last added AIL. Note that the Random Priority option can alter this rule, for more information check out the section below.
The default behavior of the plugin is to use the order used to add the AIL in the back-end to decide the parsing order of the AIL with the same priority.
The Random Prioritization option available in the Advanced tab of the plugin options can be used to modify this behavior and instead randomize the order used to apply the AIL with the same priority.
We recommended enabling this option to improve the distribution of the AIL.
Does random mean that each time a post is visited the applied AIL change?
No, the applied AIL will no change each time a post is visited. The random prioritization feature, for each post, generates a random and unique order for the AIL that have the same priority.
Why the priority of a keyword is important?
When the maximum number of AIL that can be applied to a post is limited with the Limit option of the AIL or with one of the general options provided by the plugin only the AIL with a high priority will be actually applied to the post.
More information on the methods provided by Interlinks Manager to limit the application of the AIL is available in this FAQ.
