Previously known as the Google Content Network, the Google Display Network includes a collection of websites that have partnered with Google (display partners), YouTube, and specific Google properties that display AdWords ads. These ads can be targeted automatically based on themes in your keyword list, manually (matching specific placements you select), or based on specific audiences you want to reach.
Cost per Click (CPC) is the cost for each click on a pay-per-click ad. This is automatically calculated, based on the maximum cost-per click, the daily budget, and what competitors are bidding on a particular search term.
Web traffic which comes from unpaid listing at search engines or directories is commonly known as “organic” traffic. Organic traffic can be generated or increased by including the web site in directories, search engines, guides (such as yellow pages and restaurant guides), and award sites.
Google Analytics records a visitor as ‘new’ when any page on your site has been accessed for the first time by a web browser. This is accomplished by setting a first-party cookie on that browser. Should the visitor delete their cookies and come back to the site, they would be counted as a new visitor.
