The definition of an institution is an established custom or practice, or a group of people that was formed for a specific reason or a building that houses the group of people. Marriage is an example of a cultural institution.
Contextual targeting is a type of targeting on the Google Display Network in which you select specific keywords or topics and then allow AdWords to identify websites that are a good fit for your keywords and targets.
All of these targets are too general. Targeting a specific market does not mean that you are excluding people who do not fit your criteria. Rather, target marketing allows you to focus your marketing dollars and brand message on a specific market that is more likely to buy from you than other markets. This is a much more affordable, efficient, and effective way to reach potential clients and generate business.
