Real cost of a slow website
Increase in loading time leads directly to a decrease in revenue.
Why we care about website speed?
One of the top performance improvements is undoubtedly the website speed. For past couple of years, website speed has become one of the most critical factors, so much so that even Google uses that as one of the ranking factors. There is a definite correlation between website speed and business profits.
Fast user experience is a merely good practice. We should take all efforts to make the website load faster and offer a better overall experience to the users.
Websites are getting fat, really fat! Averaging 3MB in size is massive compared to just 1MB just six years ago.
Performance impacts conversion and user engagement. Obama’s fundraising campaign during the 2011 Presidential Elections raised an additional $34 million when the Obama for America website shrunk page load time from 5 seconds to 2 seconds – that’s 14 percent increase in donation conversion with mere 3 seconds of website performance improvement!
As internet connections have gotten faster, publishers and developers worry less about efficiency.
Reduce the size of images, use external hosting for videos and prioritise JS loads and measure CPU for those asynchronous loads.
More than half of a web page size are images, so it pays off to focus on those first. Optimise your images, use SVG where possible and distribute them globally via Content Delivery Network CDN.
Cache, Compression, Minification
Utilise browser cache and gzip compression of CSS and JS files. Minify all your web assets. .
Content Delivery Network
Beyond the server that hosts your site, you can also use other networks of servers to decrease load times for your visitors. Designed to distribute static assets globally, closest to your users. We love AWS CloudFront as it has 123 Points of Presence (112 Edge Locations and 11 Regional Edge Caches) in 59 cities across 26 countries.
Build For Mobiles
Strangely, mobile web page size has overtaken desktop size in the past year. Building for mobiles should be your new priority. As of December 2017, Google took the initiative to index for mobile users first! It means that it’s in your best interest to focus on mobile users.
Slow speed kills your business. 47% of visitors expect your website to load under 2 seconds
Devastating 40% visitors will leave your site if it takes more than 3 seconds to load. These are serious implications if you are looking for a genuinely global reach either with your web application or mobile app.
Amazon discovered this a few years ago. For that megasite, every extra second it takes a page to load costs the company an estimated $1.6 billion dollars in sales each year.
The average webpage size is now the size of the original Doom game
