AJAX is a cross-platform technique that can be use on different operating system and web application based on JavaScript and DOM. It is a powerful approach of web application technique using client-side scripting to exchange data with the web server. This means that with AJAX, web pages increases interactivity and faster responsiveness of user interface by having an independent communication with the server. Gone are the traditional ways of web browsing whereby a new page communicates with each user's request. This creates dynamic web application user interface that renders effective usability of every desktop applications. AJAX primary purpose is to increase the web page's interactivity, speed, functionality, and usability.

Ajax, by definition, is not technology. In fact, it is an application of several technologies. Ajax incorporates several existing web application like XHTML and CSS for standard-based presentation; the Document Object Model for dynamic display and interaction; XML and XSLT for data interchange between the server and the client; the XMLHttpRequest to exchange asynchronous data with the web server; and the use of JavaScript as the core code for running AJAX application.

To understand AJAX, first we must know how the traditional web application works. The classic web interface trigger an HTTP request back to web server. The server then process and retrieve data before returning an HTML page to the users. This process as a model for hypertext medium makes technical sense. But as web application evolves this process does not make the user interface more interactive and practical.

AJAX, on the other hand, eliminates this problem. AJAX speed up the loading of any web application with the use of intermediary between the user and the server called AJAX engine. This adding of another layer application of eliminates the start-stop-start-stop nature on the web. The browser loads an AJAX engine at the start of session.

The AJAX engine allows the user interface and the application to interchange data asynchronously-independent of the communication to the server. So the interaction between the user and the web never slows down, no point of waiting for the server to do something.

AJAX is a powerful technique that grows exceedingly as web application. That is, AJAX is now part of the guiding principle as web 2.0 flourishes and become a practical reality. With the power of AJAX, many of the business and marketing web site are integrated with AJAX application server platform now. Most of the major products of Google such as Gmail, Google Maps, and Google Suggest are employing AJAX application. Other web services like the photo-sharing application Flickr, Amazon's A9.com, and the new Yahoo! maps depends on AJAX. The application of AJAX comes from simple function to the most complex program like Google Maps.

Millions of websites being launched year after year can only signify two important things. One, the importance of being on the net, regardless of whether yours is a small business website, a home page, an ecommerce or even a portal, and two, easy availability of variety of free templates which make website building a child's play.

In this article, let us try to explore whether templates, free or paid, offer suitability and ease of working and why they are taking the newbie web owners and builders as well as professionals by storm.

Website templates are pre made web designs into which you can start filling in your information straight after downloading. Easily, this eliminates the cumbersome task of having to design an appealing layout and more than that, it does not want you to have any knowledge of HTML at all.

At this point in time, you might be tempted to ask, if this is all, how good it is over HTML editors which don't require a template to be downloaded for every time you are building a website? True, they don't require you to possess knowledge of HTML but they still rest the task of creating an appealing layout upon you, juggling with color schemes, and placement of different sections on your page etc which are really not your job. It is precisely here that the website templates fill the void- import web templates into your favorite HTML editor and get-set-go with site building.

Conventional method of web designing is out of date as it takes a lot of manual labor a web entrepreneur can hardly afford to waste. When web presence matters to you for reasons beyond passion, you would never want to waste time and efforts on designing your own templates or even purchase them in bulk.

Free templates are in no way inferior to paid templates but you have to be choosey about your source. They do not limit your aspirations; instead you can have a variety of them such as free CSS templates, PSD templates, besides the plain HTML types. The very reason these templates are a matter of big business today is their aesthetics, functionality, easy of use and of course, the huge demand.

Free templates also make business sense considering the number of websites the ordinary people launch every month. To get your business off by launching hundreds of websites you know what makes sense and what not. Choose your templates without compromising on your needs and let the cost be condoned by the world.

A question I often ask my target market is, "what's your biggest challenge with building your business online?" And one answer I get frequently is this:

How do I make my website earn money?

If you've got a business online, then it's likely you have some sort of web presence. Perhaps it's a one-page 'sign up for my list' kind of site, or a full-blown brochure site with a menu of choices, or maybe your site is in the form of a blog. Regardless of what kind of site (or sites) you have, if they're not doing what you want them to - and since we're in business, ultimately that means making some sort of a profit - then it's time to make some changes.

But how do you REALLY know whether your site is working or not? Here are four strategies to test and track your pages to know what needs fixing:

1. Let the numbers speak

I'm sure if the sky was the limit, you'd hire the most expensive web designer with the fanciest tools to create the most spectacular site imaginable for your business - and someday you just may do that.

For now, though, even an ugly site can make money. I can think of at least two sites right now that I personally think are not that pleasing to the eye, yet I know they are raking in the bucks each and every month, year after year.

So don't get caught up in having the most polished and professionally looking site. Focus more on having the pieces in place that will bring you the cash, too.

2. Give your site only one job

Think of each page of your website as a separate entity with one main purpose. It may be to sell something, or to sign up for your list, or to get people to call you for an appointment. Whatever it is, make it clear that that one thing is the action your visitor should take from being on that page.

3. Track your numbers

Most web hosts offer statistics that you can use to watch your numbers, or there are other web stat programs that you could use as well (such as Google Analytics). However you are keeping an eye on your numbers, you should be looking for two things: how many people visit your site and how many people take the action you want them to take.

From those two numbers, you can figure out your conversion rate, which tells you how many of those visitors took the action you wanted them to - like sign up for your list. If you make small changes to your page AND watch these numbers at the same time, you'll be able to tweak things to increase your conversion rate.

4. Make one change at a time

This is a very effective way to increase the conversion rates on sales pages and sign-up pages. Change just one thing - for example, the headline - and watch your numbers. Compare those statistics to your previous ones and decide whether or not to keep the change. (You can also do this via a split-test in your shopping cart, where the software does the number crunching for you.)

I see so many sites that try to be all things to all people by offering everything under the sun in too small a space - a website - and all that does is confuse people and encourage them to click away. Remember, 'a confused mind always says no', so always go back to the main questions when considering making changes to your website: What's the purpose of this page? What is the one thing I want my visitor to do here? And then design your copy around the answer. Keep it simple and you'll get better results every time.
