Rich Media: A type of advertisement technology that often includes richer graphics, audio or video within the advertisement. Unlike static or animated GIF banner advertisements, rich media advertisements often enable users to interact with the banner without leaving the page on which it appears.

Contextual Advertising: Contextual Advertising is also known as content-targeted advertising, which means that an advertisement is shown on a web site that is "in context" to a company's specific product or service. For e.g. If one searches for Edinburgh Hotels, they would be targeted with hotel offers and packages in and around Edinburgh, alternatively, on Google, they would be subjected to the top websites, based on Google ranking, on their search page.
