According to many web development researchers Google has gone very slow in taking this step as action. They believe that, it is entirely the job of a search engine to do indexing of the content on web; Google has taken a very long time to react over this issue of reading Ajax a technology that initiated by Microsoft 10 years ago. Working over this technology was suggestible as a web search dominating power which was hidden earlier. It was the fault of Google to keep neglecting the innovative ideas for advancements. The soul role of Google as a search engine is to facilitate the user for better search. However, due to its inabilities of reading content based on Ajax and JS it was impossible to get updated for comments through web search. On the contrary some researchers believe that using Ajax and is not simple as Ajax is method to grab the data of the site but most of the time it’s captured by a something that a user can only do. One cannot expect from a search engine crawler to observe over the activities of the clicks.
Therefore, there are endless speculation and beliefs of different people in different manner over this issue. But for the user viewpoint, it is obviously a good announcement.
