Does ajax ability to load items to display?
All this I ask, given the fact that the page itself doesn't need to be updated in the browser, but that content has changed.
Is there a problem indexing such pages by search engines? Otherwise, I do not understand why news sites still the news kept on different pages, if you can configure the transition to the news list and switching to other news using ajax. Or is it just because of the banners will be displayed less and statistics site will look more poorly?
