Facebook business pages are now focused on ad placement to get your best reach to the market.. You must make a commitment to spending money by boosting your post. So to maximize the investment, it is important to place well constructed ads and then target your age or social market whom you want to reach. We have experienced good results from our investment on Facebook and we run at least 2 ad promotions per week and boost at a cost of $20-$30 per week. For longer term promotions we may spend as much as $50 for a 10-12 day promotion. We have 8900 followers and each ad reaches about 3000-3500 at a time. If you choose to spend more per ad, you will reach more people that follow your page.
