Broadly generally applies to casting a "wide net" (see below), the number of schools you apply to is directly related to how much money you want to spend, For example: I could only afford to apply to 7, some people can send out like 30 apps. If you can afford to you should apply to as many as possible so that you can be sure to net an acceptance.
Apply to some of the older schools that are generally regarded as "better or more respected within their communities" (please don't let this turn into another toxic DO ranking post):
KCU, DMU, CCOM, PCOM, etc.
Some of the schools that aren't quite as established that still have a good track record and are usually just as good as the above:
RVU, UNECOM, WVSOM, PNWU, etc.
Some new schools and branches of existing schools:
ICOM, ARCOM, PCOM Ga/South Ga, etc.
Edit: unless you are a resident of a state that has a state school, I would stay away from these because they are usually very selective when choosing any OOS students, less chance of interview with average/low stats: MSUCOM, TCOM, Ok State
