In keeping up with the growing importance of mobile, Google recently updated their guidelines for mobile  site load speeds. Specifically, Google now recommends that mobile sites load in under 1 second to avoid interrupting the user’s flow. The search engine reports that a load time under 1 second can be achieved by prioritizing above-the-fold content to load first while the rest of the site continues to render in the background.
Google established a set of best practices  for achieving sub-1 second load times for content above-the-fold:
- Server must render the response (< 200 ms)
- Minimize the number of redirects
- Minimize the number of roundtrips to first render
- Reserve time for browser layout and rendering (200 ms)
To test these elements, Google updated the PageSpeed Insights Tool  to allow developers to determine how well their sites align with these guidelines. For each URL entered, the tool provides recommendations for improving the site’s load speed and mobile performance.
These updates come in addition to Google’s official recommendation for using Responsive Web Design  as the best way to configure the same HTML across multiple devices. These guidelines should give webmasters more direction for determining how to capture the attention of the growing mobile audience.
