Should I use Facebook's Boost Post button or Ads Manager for my ads?
Use Ads Manager at adsmanager.facebook.com, not Boost post or Boost page. Facebook pushes everyone toward boosting posts and pages for small amounts, but boosting aims at vanity metrics such as page likes and post likes. Facebook knows who likes to click the like button and never pulls out a credit card, so boosting burns money and brings junk traffic that feels good but delivers no results. The only reason to boost is to get a few likes on a brand new page so your first customer is not the first person to engage with it.
In Ads Manager the structure is a campaign, which contains ad sets, which contain ads. It is easy for anyone to use: for most settings you leave the defaults, give the campaign a name, and upload your images and text. Creating a campaign asks what result you want, and you should choose Leads or Sales.
Votel also lets you create and manage ads inside the platform, in Ads Manager under Click Tracking.
