All that gorgeous photography and stylized copy that makes your product sell so well — it’s also what’s taking precious seconds to load when you call up your site on a smartphone. You need rich media to properly showcase what you’re selling, but you also need your site to be speedy enough to load quickly on small screens and conform to web standards. Amazon estimates that every extra 100 milliseconds it takes a page to load cuts its profits by 1 percent. It’s not just that users won’t wait around for 10, 20 seconds for your site to load — Google uses site speed in its search rankings. Slow sites will take an SEO hit, hurting the odds of your customers finding you organically — i.e. without paid advertising.
MIT tested Polaris on 200 of the world’s most-visited websites, and reduced load time by an average of 34 percent. The framework does the most good for complicated sites like NYTimes.com or Weather.com — where an abundance of content creates multiple dependencies.
Polaris differs from other efforts to speed up sites. It doesn’t rely on data compression to reduce the size of information transferred, it just seeks to reduce the number of trips it takes to transfer it. It can work on any browser, meaning it could potentially give all users a faster page load-time. And unlike Google’s AMP project and Facebook’s Instant Articles, it doesn’t require changes to the content. For it to live up to its potential as a universal solution, though, two things need to happen:
- Webmasters need to run the Polaris software on their sites’ servers to map the dependencies
- Browsers need to incorporate Polaris as well
This week, MIT PhD student Ravi Netravali, the first to author a paper on Polaris, will present his findings. If browsers are intrigued and start adopting the framework, having Polaris running to map your site dependences could quickly become a competitive advantage.
