The disadvantages are:
a)Ajax is not so friendly with search engine indexing because it uses Javascript for much part of its code. Search engines generally do not index Javascript present in web pages.
b)Dynamically created pages created by ajax does not support back button which takes the user to the previous pages.

The disadvantages of AJAX are:

  • Search engines would not be able to index an AJAX application.
  • The server information can not be accessed within AJAX.
  • AJAX is not well integrated with any browser.
  • ActiveX requests are enabled only in IE 5 and IE6
  • Data of all requests is URL-encoded, which increases the size of the request

Disadvantages of using AJAX

One big disadvantage of using AJAX is security. Often times developers do not put checks on the data coming into the server - they assume that it's coming from their own website. Unfortunately, this is subject to injection attacks.
Furthermore, there is several ways to "fake" how the data is coming in, making detection all but impossible.

1. Javascript dependency
2. View source is allowed and anyone can view the code source written for AJAX
3. Debugging is difficult.
4. Complexity of the code makes it difficult for web developers.
