The best way to ensure that your pizza won’t become soggy is to go light on the sauce.  In fact, I’ll sometimes cook it without the sauce at all.  This way it is more of a cheese bread with toppings, and then you can heat the sauce to serve as a dip on the side. You also want to avoid assembling these ahead of time, unless you plan on freezing them.  Be sure to make the recipe, then immediately pop those babies into the oven.
