Page speed matters in web design

Page speed was important back in 2000 when I started working online. Most people had dial-up modems meaning top speeds were around 50 kb per second for home connections. Broadband was a thing of the future, as was YouTube, Twitter, Facebook and Google Plus.

So why does it matter now in an age of broadband? Why should we still strive to build light pages and efficient code?

1) The world is turning mobile. By the end of 2013 there will be more mobile devices than people. But 3G connections can still be slow. Optimised design means fast loading for short attention spans and a web experience that feels like it’s responsive. If a page won’t load on a slow connection, people press the back button.

2) Attention spans are shorter than ever. We have more information, more distractions than ever before. People don’t want to wait for anything. Faster page load times mean more attention, more engagement from users. We have to design for short attention spans, including page weight.

3) Google likes it and rewards it. Google likes fast page speeds because customers like it. The total experience you give customers down to page speed is critical to where Google ranks you because their job is to provide the most relevant and the best results. And they’ve been incorporating into the search engine algorithms since 2010 (see: http://www.mattcutts.com/blog/...)

How do I measure my page speed?

Tactics for speed

  • Run the page speed tool above for technical advice
  • Check content management systems for bloated code & slow plugins
  • Optimise all images on your website
  • On large and heavy traffic sites, use Sprite maps. Think of it as a single image with all your most used images, which stops your browser grabbing images from everywhere.

Can you improve the perceptual speed of your site?

Yes, this tool shows you how specific changes and improvements can lead to your page being perceived to load much faster:

We have just launched a new app to help reduce waiting times in hospitals across Devon and Cornwall. The app, NHSquicker, allows people to view up-to-date waiting times for local emergency departments and minor injuries units. It also provides information regarding distance and time to different treatment centres, based on the user's location. Reactor15 have been working with Exeter Health and Care IMPACT Network, a collaboration between the NHS across Devon and Cornwall and academics from the University of Exeter to build an app which is widely available for smartphones and tablets, on Apple and Android. The NHSquicker app took six months to build and is a fully native app developed using our own custom framework. Using a native platform which allowed us to build a fast, responsive and reliable experience to users, when accuracy and speed of information is very important. The app also provides information about less urgent NHS services, including GPs, pharmacies, sexual health services, dentists and opticians. Mike Saunders, Managing Director of Reactor15 said: "It’s great, once again, to be involved in building a really useful NHS tool. We were asked to build an app which will not only help reduce waiting times in our local hospitals but will also help patients make the right choices with regards to how and where they receive their treatment. We believe our native app platform is both robust and versatile enough to meet the needs and brief of Exeter Health and Care IMPACT Network." Reactor15 have a good working relationship with the NHS and have already built the award winning HANDi Paedatric, POPs apps and the Devon and Wakefield Formularies. NHSquicker can be downloaded on iTunes and Google Play.
