The to timeout limits What about JavaScript that executes some time after the page loads This will generally only be indexed up to some time limit possibly in the region of seconds What about JavaScript that executes on some user interaction such as scrolling or clicking This will generally not be included What about JavaScript in external files rather than inline This will generally be included as long as those external files are not blocked from the robot though see the caveat in experiments below For more on the technical details I recommend my excolleague Justins writing on the subject.
A highlevel overview of my view of JavaScript best practices Despite the incredible Europe Cell Phone Number List workarounds of the past which always seemed like more effort than graceful degradation to me the right answer has existed since at least with the introduction of PushState. Rob wrote about this one too. Back then however it was pretty clunky and manual and it required a concerted effort to ensure both that the URL was updated in the users browser for each view that should be considered a page that the server could return full HTML for those pages in response to new requests for each URL and that the back button was handled correctly by your JavaScript.
Along the way in my opinion too many sites got distracted by a separate prerendering step. This is an approach that does the equivalent of running a headless browser to generate static HTML pages that include any changes made by JavaScript on page load then serving those snapshots instead of the JSreliant page in response to requests from bots.way that Google tolerates as long as the snapshots do represent the user experience. In my opinion this approach is a poor compromise thats too susceptible to silent failures and falling out of date. Weve seen a bunch of sites suffer traffic drops due to serving Googlebot.
