Hello I am Brad .From some few days I wished to make a website for my own. Being a non technical Is was very difficult for me to sort out the best company, who can satisfy me. There are many list of company in various search engines like Google , yahoo, altavista etc. But they are not my type because budget is always a factor for me. At that moment one of my close friend “John” told me about “ Encoders “ . and it was a great experience for me when I talk with Encoders at their live support and find the best quality service provider in cheap rate. And the most important thing is that they have the ability to satisfy their clients and meeting deadline carefully. After finding Encoders I tell them clearly about my requirements and they assured me that my website will ready within 15 days in just 10$$ per hour rate . Isn't it sounds very interesting to all of you?? I feel extremely fortunate to have found Encoders and confident that our website will give us a distinct advantage over our competitors. All of you who are new to build a website for yourself or your business can contact with “ Encoders “ . It will be very helpful and cost effective for you all. Be a client I can say that it would be profitable for all of you to build website from Encoders , the India based we development company.

Pay per click (PPC) is an Internet advertising model used on search engines, advertising networks, and content websites, such as blogs, where advertisers only pay when a user actually clicks on an advertisement to visit the advertisers' website. With search engines, advertisers typically bid on keyword phrases relevant to their target market. When a user types a keyword query matching an advertiser's keyword list, or views a webpage with relevant content, the advertisements may be displayed. Such advertisements are called sponsored links or sponsored ads, and appear adjacent to or above the "natural" or organic results on search engine results pages, or anywhere a webmaster or blogger chooses on a content page. Content websites commonly charge a fixed price for a click rather than use a bidding mechanism.Although many PPC providers exist, Google AdWords, Yahoo! Search Marketing, and Microsoft adCenter are the largest network operators as of 2007. Minimum prices per click, often referred to as costs per click (CPC), vary depending on the search engine and the level of competition for a particular phrase or keyword list—with some CPCs as low as US$0.01. Very popular search terms can cost much more on popular search engines. The PPC advertising model is open to abuse through click fraud, although Google and other search engines have implemented automated systems to guard against abusive clicks by competitors or corrupt webmasters.

Pay per click campaigns can be categorized into two major categories: sponsored match (or keyword) and content match. Sponsored match campaigns involve the display of advertisements on search engine results pages, whereas content match campaigns involve the display of advertisements on publisher websites, newsletters, and e-mails.
There are other types of pay per click programs that target product or service searches and product comparison sites. Search engine companies may participate in more than one category. PPC programs do not generate any revenue solely from Web traffic for websites that display the advertisements: Revenue is generated only when a user clicks on the advertisement itself.

Ajax (asynchronous JavaScript and XML), or AJAX, is a group of interrelated web development techniques used for creating interactive web applications or rich Internet applications. With Ajax, web applications can retrieve data from the server asynchronously in the background without interfering with the display and behavior of the existing page.Data is retrieved using the XMLHttpRequest object or through the use of Remote Scripting in browsers that do not support it. Despite the name, the use of JavaScript, XML, or asynchrony is not required.

The term Ajax has come to represent a broad group of web technologies that can be used to implement a web application that communicates with a server in the background, without interfering with the current state of the page. In the article that coined the term Ajax, Jesse James Garrett explained that it refers specifically to these technologies:

    * XHTML and CSS for presentation
    * the Document Object Model for dynamic display of and interaction with data
    * XML and XSLT for the interchange and manipulation of data, respectively
    * the XMLHttpRequest object for asynchronous communication
    * JavaScript to bring these technologies together

Since then, however, there have been a number of developments in the technologies used in an Ajax application, and the definition of the term Ajax. In particular, it has been noted that:

    * JavaScript is not the only client-side scripting language that can be used for implementing an Ajax application. Other languages such as VBScript are also capable of the required functionality.
    * the XMLHttpRequest object is not necessary for asynchronous communication. It has been noted that IFrames are capable of the same effect.
    * XML is not required for data interchange and therefore XSLT is not required for the manipulation of data. JavaScript Object Notation (JSON) is often used as an alternative format for data interchange, although other formats such as preformatted HTML or plain text can also be used.

JavaScript is a scripting language most often used for client-side web development. It was the originating dialect of the ECMAScript standard. It is a dynamic, weakly typed, prototype-based language with first-class functions. JavaScript was influenced by many languages and was designed to look like Java, but be easier for non-programmers to work with.Although best known for its use in websites (as client-side JavaScript), JavaScript is also used to enable scripting access to objects embedded in other applications .JavaScript, despite the name, is essentially unrelated to the Java programming language, although both have the common C syntax, and JavaScript copies many Java names and naming conventions. The language was originally named "LiveScript" but was renamed in a co-marketing deal between Netscape and Sun, in exchange for Netscape bundling Sun's Java runtime with their then-dominant browser. The key design principles within JavaScript are inherited from the Self and Scheme programming languages."JavaScript" is a trademark of Sun Microsystems. It was used under license for technology invented and implemented by Netscape Communications and current entities such as the Mozilla Foundation.

FEATURES

Structured programming

JavaScript supports all the structured programming syntax in C (e.g., if statements, while loops, switch statements, etc.). One partial exception is scoping: C-style block-level scoping is not supported. JavaScript 1.7, however, supports block-level scoping with the let keyword. Like C, JavaScript makes a distinction between expressions and statements.

[edit] Dynamic programming

dynamic typing
    As in most scripting languages, types are associated with values, not variables. For example, a variable x could be bound to a number, then later rebound to a string. JavaScript supports various ways to test the type of an object, including duck typing.[8]
objects as associative arrays
    JavaScript is heavily object-based. Objects are associative arrays, augmented with prototypes (see below). Object property names are associative array keys: obj.x = 10 and obj["x"] = 10 are equivalent, the dot notation being merely syntactic sugar. Properties and their values can be added, changed, or deleted at run-time. The properties of an object can also be enumerated via a for...in loop.
run-time evaluation
    JavaScript includes an eval function that can execute statements provided as strings at run-time.

[edit] Function-level programming

first-class functions
    Functions are first-class; they are objects themselves. As such, they have properties and can be passed around and interacted with like any other object.
inner functions and closures
    Inner functions (functions defined within other functions) are created each time the outer function is invoked, and variables of the outer functions for that invocation continue to exist as long as the inner functions still exist, even after that invocation is finished (e.g. if the inner function was returned, it still has access to the outer function's variables) — this is the mechanism behind closures within JavaScript.

[edit] Prototype-based

prototypes
    JavaScript uses prototypes instead of classes for defining object properties, including methods, and inheritance. It is possible to simulate many class-based features with prototypes in JavaScript.
functions as object constructors
    Functions double as object constructors along with their typical role. Prefixing a function call with new creates a new object and calls that function with its local this keyword bound to that object for that invocation. The function's prototype property determines the new object's prototype.
functions as methods
    Unlike many object-oriented languages, there is no distinction between a function definition and a method definition. Rather, the distinction occurs during function calling; a function can be called as a method. When a function is invoked as a method of an object, the function's local this keyword is bound to that object for that invocation.

[edit] Others

run-time environment
    JavaScript typically relies on a run-time environment (e.g. in a web browser) to provide objects and methods by which scripts can interact with "the outside world". (This is not a language feature per se, but it is common in most JavaScript implementations.)
variadic functions
    An indefinite number of parameters can be passed to a function. The function can both access them through formal parameters and the local arguments object.
array and object literals
    Like many scripting languages, arrays and objects (associative arrays in other languages) can be created with a succinct shortcut syntax. The object literal in particular is the basis of the JSON data format.
regular expressions
    JavaScript also supports regular expressions in a manner similar to Perl, which provide a concise and powerful syntax for text manipulation that is more sophisticated than the built-in string functions.
