Google Answers

Google Answers is an interesting cross etween 'online marketplace' and probably a 'virtual classroom'. Those who wish to participate must register with Google Answers. Here, the researchers who have considerable expertise in online researching provide answers to the queries posted by other users for a fee.

When a user posts a question, he or she also needs to mention the price the user is willing to pay in case the question is answered. When the question is answered by any user, then the payment is made accordingly to the user answering the question. Moreover, the questions and the discussion that ensues will be publicly viewable and other registered users can also share their opinions and insights.

There is a non-refundable listing fee of $0.50 per question plus an additional 'price' you set for your question that reflects how much you're willing to pay for an answer. Three-quarters of your question price goes directly to the Researcher who answers your question; the remaining 25 percent goes to Google to support the service.

Google Groups

Google Groups is an online discussion forum and it contains the entire archive of Usenet discussion groups dating back to 1981. These discussions cover the full range of human dissertation and present a fascinating look at evolving viewpoints, debate and advice on every subject from politics to technology. Users can access all of this information all in a database that contains more than 800 million posts by using the search feature of Google.

Google's Image Search

Google offers a wide collection of images from around the web; its comprehensive database consists of more than 425 million images. All a user has to do is to enter a query in the image search box, then click on the "Search" button. On the results page, by clicking the thumbnail a larger version of the image can be seen, as well as the web page on which the image is located. By default, Google's Image Search uses its mature content filter on the initial search by any user. The filter removes many adult images but it cannot guarantee that all such content will be filtered out. It is not possible to ensure with 100% accuracy that all mature content will be removed from image search results using filters.

Google's Catalog Search

Google offers a unique service in the form of its Catalog Search. Google's Catalog Search has made it easy to find information published in mail-order catalogs that were not previously available online. It includes the full content of hundreds of mail-order catalogs selling everything from industrial adhesives to clothing and home furnishings.

Froogle

The word 'froogle' is a combination of the word 'frugal' which means 'penny-wise' or 'economical' and of course 'Google'. Google's spidering software crawls the web looking for information about products for sale online. It does so by focusing entirely on product search and applying the power of Google's search technology to locate stores that sell items you want and consequently pointing you to that specific store.

Just like the Google Web Search, Froogle also ranks store sites based only on their relevance to the search terms entered by the users. Google does not accept payment for placement within their actual search results. Froogle also includes product information submitted electronically by merchants. Its search results are automatically generated by Google's ranking software.
