Vertical Search Vertical search, part of a larger subgrouping known as "specialized" search, is a relatively new tier in the Internet search industry consisting of search engines that focus on specific slices of content. The type of content in special focus may be based on topicality or information type. Vertical search may focus on all manner of differentiating criteria, such as particular locations, multimedia object types and so on. E.g. a. A medical search engine would clearly be specialized in terms of its topical focus b. A video search engine would seek out results within content that is in a video format. Type of Vertical search design In terms of design and implementation, several models are emerging in vertical search: The vertical search engine as a destination or portal. Often media companies that own these destination sites optimize them and buy keywords on Google to drive their audience to visit. Vertical search as a complementary Web site applicatio

many web publishers, web servie men need to determine how to improvw user satisfaction: Constant availability and security remains a very high priority for most organizations. However it si difficult some times. For e.g. ubiquity of e-mail makes it difficult to measure. major concerns: 1. What do our users do with it? 2. How do they measure server reliability and stability? 3. Do users want improvement in service? Measurements need to be build to measure the black box :user satisfaction 1. Service availability- Apart from availability we need to consider utilization, functionality, or impact 2. Need to research on user community In order to measure that, we needed to apply customer service style measurements. To what extent, though, do they really use it? How many of the features do they use, for what, and to what degree?

First let me introduce to concept of back links Backlinks are links that are directed towards a webpage. Popularly called Inbound links. The number of backlinks to a webpage act as vote for the webpage. It also adds to the popularity of the webpage. Google's first published algorithm is based on Page rank. According to the Page rank algorithm inbound links are counted as vote for the page and outbound as links as votes which the webpage provides to other pages. Since back links are immense part of page rank algorithm they are important from a Search Engine optimizer point of view. Backlinks need to be quality backlinks for better ranking of web page According to Search Engine a backlink is a quality backlink if it is relvant for the keyword for which it has been created. further theme of the voting website is similar to the theme of the voted website. Thus we cannot be satisfied with merely getting inbound links we need to keep a check on the quality of the inbound lin

Push Technology Push technology, or server push, is a style of Internet-based communication where the request for a given transaction originates with the publisher or the server. It is in contrast with pull technology, where the request for the transmission of information originates with the receiver or the client. General use Push services are often based on information preferences expressed in advance. This is known as a publish/subscribe model. A client might "subscribe" to various information "channels". Whenever new content is available on one of those channels, the server would push that information out to the user. Synchronous conferencing and instant messaging are typical examples of push services. Chat messages and sometimes files are pushed to the user as soon as they are received by the messaging service. Both decentralized peer-to-peer programs and centralized programs allow pushing files, this means the sender initiates the data transfer rathe

Pull Technology Pull technology or client pull is a style of network communication where the initial request for data originates from the client, and then is responded to by the server. The reverse is known as push technology, where the server pushes data to clients. Pull requests form the foundation of network computing, where many clients request data from centralized servers. Pull is used extensively on the Internet for HTTP page requests from websites. A push can also be simulated using multiple pulls within a short amount of time. For example, when pulling POP3 email messages from a server, a client can make regular pull requests every few minutes. To the user, the email then appears to be pushed, as emails appear to arrive close to real-time. The tradeoff is this places a heavier load on both the server and network in order to function correctly. Most web feeds, such as RSS are technically pulled by the client. With RSS, the user's RSS reader polls the server periodi
