1. Backed up by Renowned Brands
Ajax has been backed up by some renowned names and several complex applications are built using this technology. Google Maps is one of the most impressive sites built using Ajax, Pandora an online music market also use Ajax, vBulletin forum software has also included Ajax in their latest version. Some other giants using Ajax are Blockbuster, HollywoodVideo and Amazon.
3. Ajax not used for Content
If you are thinking of using Ajax on your website first decide whether data you are accessing changes because the purpose of asynchronous call is to make request to the server when information is changing frequently and you don’t want to reload the whole page. Some scenarios where Ajax calls work perfectly are form validation, add comments, filtering data etc.
4. Refresh and Back Button are of no use
As the functions in AJAX are loaded dynamically the page does not get reloaded therefore the URL remains the same. The problem occurs when you click the refresh or back button, it takes you to a different web page or to the beginning of processed dynamic web page. This can be considered as a major drawback in AJAX but you can solve it by using iframe and a hash in the url or by showing some good programming skills.
5. Faster Development
Ajax is not tightly coupled with any of the particular web technologies. This gives it flexibility and ease of use with any technology like Java, PHP or ASP.Net. As the time is passing AJAX is becoming more powerful, many advance features are now available in plug and play format. This greatly reduces the development effort.

The most common issue faced by network administrators which support Ajax applications is that they have to continuously serve http responses which can be big enough. This leads to extra load on application servers which send the response frequently. So before using Ajax in your application make sure that developers understand the network impact of these applications and do not overload the server.

9. XML is not mandatory
Ajax does not require XML as XMLHttpRequest object can use any text format. For passing input into documents developer can use HTML fragments, raw text, YAML, comma separated values etc. Though it is reasonable to use XML as binary formats is not supported by XMLHttpRequest object.
