All posts/listings in Voxel have by default a priority of 0. The priority level can impact the ranking of that post in search results. It can also be used to feature posts on certain parts of the site of your choosing.
Using Voxel custom orders, you can also create custom ordering with multiple clauses e.g Ranked by priority as first clause and rating as second clause.
The priority of a post can either be changed manually through back-end or through Promotion packages in front-end. Promotion packages change the priority level of that post for limited time for a fee.
