There isn't exactly a be-all, end-all pizza topping combo. There are classic ones, but beyond that it boils down to personal taste and proper usage of flavor profiles. It sounds like this is part of your food blog, so don't forget to mention things like sauces, additional toppings, flavors of cheese, seasonings, bastes, etc. You would also be remiss not to mention the crust and presentation styles, which is huge for pizza.
