Demo targeting or Demographic targeting and what it does for Display (SEM) advertising? by Aubrey Owen
Demo: When determining the demographic of potential customers, you will have to determine whether display ads will appeal to a certain age group, family size, single, students, income, etc. This will help eliminate deals that do not apply to certain needs and prevents a potential customers from being annoyed by your business. This will come in handy when a deal does apply to their needs since your business will not be remembered as the business that kills trees or wastes paper.
This strategy also helps weed out people that are not your target audience so your target customers are contacting you.
