So now Google has deprecated AJAX crawling scheme. They say not to bother implementing it in new websites, because it's no longer needed since Googlebot has now no problem watching dynamic content. Should we immediatly trust this statement, or better to adhere to the deprecated standard for a while?

Several other search engines (Bing, Yandex, etc.) still use the _escaped_fragment_ system. They're not going to stop using it overnight just because Google has. Thus, if you care about your site being indexable by search engines other than Google, you may want to still support this scheme.

Certainly, if you already have set up support for _escaped_fragment_ on your site, there's no reason to disable it. If you're developing a new site, you'll need to weigh the cost of adding this feature against the benefits (keeping in mind that Google currently has a near-monopoly on Internet search, and that in any case, other search engines will likely soon scramble to follow Google's example and implement better crawling of dynamic Ajax-loaded content).

Finally, note that in most cases, the simplest and most foolproof solution is to implement your site so that it doesn't need such tricks in the first place. At least 99% of the time, you don't really need any Ajax, or even client-side scripting at all. By avoiding unnecessary reliance on Ajax, and by designing your site so that at least basic browsing features work even with JavaScript disabled, you'll ensure the widest possible compatibility across browsers and search engines.

The trick to doing this efficiently is to first set up the basic functionality of your site using basic HTML and CSS and plain old links, with no JS at all. Once you've done that, you can add JS and Ajax on top of that for smoother loading and extra features, while still retaining a graceful fallback interface for users and search engines who don't support the extra features. If you start out relying on Ajax for everything, however, retrofitting a non-Ajax fallback interface later can be very difficult and awkward.

    Also keep in mind, you might also need to support social media services. Last time I checked, Facebook still shares moustache titles as " foobar - {{page.title}}" if you don't use some kind of prerendering.

Google already crawls and processes JavaScript so there is no need to implement the AJAX crawling scheme in new sites.
