The Facebook ad system. What is it? It's a self-serve digital ads platform that enables businesses of all sizes, be it very small or very large, to advertise at scale to real people across their devices and at each stage of the purchasing journey. There are over two billion people on the platform that you could reach to and almost one-to-one level or in the millions.

Any business, as I mentioned, of any size, can grow their business.

When building a campaign on Facebook, it's important to know that it's a three-tiered structure to prepare for the campaign on the Facebook ads platform. At campaign level, the objectives are set to determine what you want to accomplish with an ad. At ad set level, you select the audience you want to target, where you want to place the ads, what amount of budget you wish to spend, and also the time schedule of the ads. At ad level, you can select the ad format you wish to use, and then select either the Facebook page or Instagram profile where the ads will come from, and you can input whichever link you wish to send people too. It's good to note that within a campaign, there can be as many ad sets as you wish. You can get as many audiences and placements you wish to go to. But within the ad set, you can have as many ads you like. But the best practice would be to have 4-6 ads in order to get the optimum delivery and return for that ad set.
