Contextual advertising is a type of online advertising commonly used for content-based websites. With contextual advertising, targeted ads appear based on the page’s actual content.
First, a contextual advertising system scans the text of a webpage for keyword phrases. Then, the system returns specific, targeted ads based on the content people are viewing.
If a person is looking at a page of art supplies, the ads in those pages would be of art suppliers, painting sellers, online art museums, and such.
Contextual ads appear as:
Separate ads that are placed in specific areas of the page
Inline or in-text contextual ads
Sponsored links ads
Generally these ads are text ads with links to the related websites. The website owner can choose the location on his website where he would like to place contextual ads. Your ad will come in a box labeled sponsored links. You will need to use the services of pay-per-click search engines to do contextual advertising. This format is popularized by Google Adwords and Adsense.
Inline ads appear in the form of links to the text phrases in the content of the website. When the mouse hovers over that phrase, a short description will come in a box that looks like a tool-tip. If the reader wishes to know more, he can simply click on the link.
