The order of posts in a category determines the order in which they are published (after priority is taken into account).
How to reorder
On the category page, drag and drop posts using the handle on the left side of each row. The new order is saved automatically.
Tip: Combined with priority, reordering gives you precise control over your publishing sequence. Use priority for the most urgent posts and drag-and-drop to fine-tune the order of the rest.
