previous blog post, we discussed an ongoing problem uncovered by our Mobile Experience Scorecard report on the Fortune 100 – sites using Responsive Web Design (RWD) take significantly longer to load then dedicated mobile sites or desktop sites. Yet using RWD remains an industry best practice because of the significant advantages it offers over other configurations. Fortunately, there are a number of tactics that, when implemented, can minimize the load speed to align with that other, elusive best practice of keeping load speeds under 1 second. The overarching strategy for minimizing load speed is streamlining mobile sites by eliminating all unnecessary parts, leaving only the most essential components. Adhering to Google’s PageSpeed Insight Rules is a great place to start. Here are some of the more common issues:
- Optimize images by reducing unnecessary data and minimizing file sizes.
- Serve scaled images at the size they should be, as opposed to loading large images and shrinking them to fit the space.
- Focus on loading “above the fold” content first, before loading additional scripts.
