GWT Interview Questions and Answers
Ques 11. What are the disadvantages of GWT?
Ans. Problems with indexing by search engines - IMHO, this should be the biggest disadvantage of using GWT, or pure JS web applications in general. Since the content, layout, everything is created \"on-the-fly\" with JS, the search engine will only see a very short HTML page and that\'s that - you have to take care of this somehow yourself (for example, using cloaking). Google has finally started to work on a solution for this, however it doesn\'t seem to attractive to me.
Update: Google has finally addressed this problem. However, I\'ll leave this as a trade-off because making the application crawable still requires more effort than in other frameworks. At least now we have a \"standard\" to follow and don\'t have to use some dubious techniques (like cloaking).
