You should know that everything you can do while boosting a post, you can also do when you create an ad. Creating an ad, while a bit more work, does give you more options.
Also, unlike boosting a post, creating an ad requires that you have Business Manager which gets you access to Ads Manager where you will create your ad. So there is additional setup, but you only have to do it once.
When you create an ad in Ads Manager, you also set up a campaign. Setting up a campaign allows you to choose an objective such as “Traffic,” “Brand Awareness,” or “Conversions.” Choosing an objective helps Facebook optimize your pixel for the campaign, which theoretically gets you better results.
By creating an ad, you also get access to several more ad types, such as “Lead Ads,” “Canvas Ads,” and “Collections.” Depending on what you are promoting, these additional ad types may be important.
As mentioned above, depending on your campaign objective and type of ad, you will get additional CTAs by creating an ad, such as “Apply Now,” “Contact Us,” “Donate Now,” “Get Showtimes,” “Listen Now,” and “Download.”
When you create an ad, you can also set up multiple ad sets for your ad, which means you can run the ad to several different audiences simultaneously. This can come in handy when you are trying to zero in on your best audience. Also, unlike a post you are boosting, your ad doesn’t have to appear on your Facebook business page.
