The developers and designers have begun to realize that better user-experience plays a vital role in market success. The success of Ajax-based applications such as Google Maps over more traditional alternatives like MapQuest show that the products that offer better user experience will be successful. Ajax is a big contributor in making web applications usable. It eliminates page refresh problems and improves slow response that has affected web applications since their inception. The cause behind this is it allows pages to request small bits of information from the server instead of whole pages. People always want decent user interfaces and are eager to invest in it.

Using JavaScript technology, an HTML page can asynchronously make calls to the server from which it was loaded and obtain content that may be formatted as XML documents, HTML content, plain text or JavaScript Object Notation (JSON). The JavaScript technology may then use the content to update or modify the Document Object Model of the HTML page. The term Asynchronous JavaScript Technology and XML has emerged in recent times to explain this interaction model.

The solitary utmost SEO issue with Ajax is the propensity of Ajax applications not to sensibly create unique, bookmarkable and therefore indexable URLs. Take the example of Google Maps which is a genuine Ajax application. If you have brand awareness like Google, you don’t essentially need too many deep, internal URLs, because everyone remembers and links to “maps.google.com”. But for the rest of us, getting many internal pages indexed is critical. Google puts the “Link to this page” feature on the Maps page. Because they understand the need for unique URLs pulled from within the application. You can adopt a similar philosophy to derive a lot of benefits from using an Ajax application.

The other issue is that once you have built the capability to generate unique internal URLs, you will need to post them at places, so they can be crawled. You will also need a structure that can create custom, related titles and meta descriptions for these deep URLs, since the amount of body copy on a page likely, won’t be particularly abundant or relevant.

There is always hot debate going on regarding which is better, Ajax or Flash. Both the technologies have certain advantages and disadvantages in specific situations. But there is a lot of scope for them to work together. Many developers have understood this to implement some really great software using both Ajax and Flash together. It is also absolutely compatible with any standard web server and server-side language such as PHP, ASP, ASP.Net, Perl, JSP, Cold Fusion and many more. This has helped move Ajax further because all web developers can use and talk about a common presentation layer.

If you scroll through Live.com’s infinite results long enough, the “offset” argument starts to move upwards. Before you understand what is happening, you will be at “offset=20″ or something like that. But the actual problem starts when you decide to hit the back button and go to your previous site. You’ll need to click the button 20 times to get back to that site, since each time you hit it, you only decrement the offset argument by one.
