We published articles here before that talks about AJAX programming and the impact it has on search engines. AJAX allows applications on the web to provide a better and more interactive user experience; it does not require a user to refresh a page or follow a link to see more content, yet the content seamlessly become available by the actions user take on the site. This has a huge impact on the search engine. Although there are some controversial fixes the content seems mainly to remain inaccessible to the search engine crawlers.

Although AJAX adds interactive features to a site, it still follows the traditional response/request architecture of the web. For the content to become available an action by the user is required, this action such as a “mouse click” sends an HTTPRequest and receives an HTTPResponse from the server. In addition to the user action, continues polling or frequent and timely requests can make this possible but the technique is not efficient and consumes a lot of bandwidth and resource on the server.

To fix the problems with the application responsiveness and interactivity, HTML5 offers Server-Sent event and Worker Processes. The Server-Sent event has a profound effect on the web and changes the way we access information on the web. This truly makes the web upside-down with no request/response architecture to follow. To learn more about the HTML Server-Sent event click here. HTML5 Worker Process likewise employs user’s computer power instead of the consuming resources on the server to calculate complex mathematical operations or performs data analysis; the results of these processes would not be available to search engines too.

AJAX programming along HTML5 Server-Sent and Worker Process are search engines nightmares, as we noted before search engines have to use other ways to crawl and index content on the web, it will become increasingly more difficult for search engines to crawl next generation apps that are comprised of AJAX or HTML5 components.

Feed in its RSS or Atom format more likely to become the preferred method for site content distribution and increasingly being crawled by search engines to find new content on the web.
