What is the difference between Priority on the banner ad and the Priority Placement selection on the Marketing tab?
Priority Placement on the Marketing tab relates to the selection of members to display in the search results of the business directory listing. All Enhanced/Gold members are automatically assigned 30 which will randomly display their listing among all other Enhanced/Gold members with a 30 Priority Placement. Members that are not Enhanced/Gold are defaulted to 10 Priority Placement which will randomly display their listing among all other Basic members with a 10 Priority Placement. You may assign different Priority Placement numbers as desired which will randomly display their listing among all others with that same Priority Placement number. Those with Higher Priority Placement numbers will display first within the Business Directory Search Results.
