Running PPC ads are invariably a part of a larger marketing campaign that’s a series of marketing activities working towards a common goal.
An AdWords campaign contains all of your ad groups and those ad groups themselves contain your ads. The most interesting things occur when we get to ad groups that contain all of the ads that are targeted at a shared set of keywords, which are in fact user’s search queries. For example, one ad group may have 15 different ads all targeting the keywords like shoes, shirts, shawls, boots and gloves for feet etc. See more @ http://www.digitalmarketing.limited/category/sem/
