Social innovation

Social innovation refers to new strategies, concepts, ideas and organizations that meet social needs of all kinds - from working conditions and education to community development and health - and that extend and strengthen civil society.

Over the years, the term has developed several overlapping meanings. It can be used to refer to social processes of innovation, such as open source methods. Alternatively it can be used to innovations which have a social purpose - like microcredit or distance learning. The concept can also be related to social entrepreneurship (entrepreneurship isn't always or even usually innovative, but it can be a means of innovation) and it also overlaps with innovation in public policy and governance. Social innovation can take place within government, within companies, or within the nonprofit sector (also known as the third sector), but is increasingly seen to happen most effectively in the space between the three sectors.

Electronic commerce

Electronic commerce , commonly known as e-commerce or eCommerce, consists of the buying and selling of products or services over electronic systems such as the Internet and other computer networks. The amount of trade conducted electronically has grown extraordinarily since the spread of the Internet. A wide variety of commerce is conducted in this way, spurring and drawing on innovations in electronic funds transfer, supply chain management, Internet marketing, online transaction processing, electronic data interchange (EDI), inventory management systems, and automated data collection systems. Modern electronic commerce typically uses the World Wide Web at least at some point in the transaction's lifecycle, although it can encompass a wider range of technologies such as e-mail as well.

Contemporary electronic commerce involves everything from ordering "digital" content for immediate online consumption, to ordering conventional goods and services, to "meta" services to facilitate other types of electronic commerce.

On the consumer level, electronic commerce is mostly conducted on the World Wide Web. An individual can go online to purchase anything from books, grocery to expensive items like real estate. Another example will be online banking like online bill payments, buying stocks, transferring funds from one account to another, and initiating wire payment to another country. All these activities can be done with a few keystrokes on the keyboard.

AdWords

AdWords is Google's flagship advertising product and main source of revenue ($16.4 billion in 2007). AdWords offers pay-per-click (PPC) advertising, and site-targeted advertising for both text and banner ads. The AdWords program includes local, national, and international distribution. Google's text advertisements are short, consisting of one title line and two content text lines. Image ads can be one of several different Interactive Advertising Bureau (IAB) standard sizes.

Google's AdWords division is based in Ann Arbor, Michigan, the company's third-largest facility behind its Mountain View, California, headquarters and New York City office.

All AdWords ads are eligible to be shown on www.google.com. Advertisers also have the option of enabling their ads to show on Google's partner networks. The "search network" includes AOL search, Ask.com, and Netscape. Like www.google.com, these search engines show AdWords ads in response to user searches.

The "content network" shows AdWords ads on sites that are not search engines. These content network sites are those that use AdSense, the other side of the Google advertising model. AdSense is used by publishers who wish to bring traffic to their websites. Click through rates on the content network are typically much lower than those on the search network and are therefore ignored when calculating an advertiser's quality score.

Google automatically determines the subject of pages and displays relevant ads based on the advertisers' keyword lists. AdSense publishers may select channels to help direct Google's ad placements on their pages, to better track performance of their ad units. There are many different types of ads you can run across Google's network, including text ads, image ads (banner ads), local business ads, mobile text ads, and in-page video ads.

Google AdWords' main competitors are Yahoo! Search Marketing and Microsoft adCenter.
