Accessibility

If your website takes more than three seconds to load, you need to look at optimizing your website. Users nowadays are lazy and impatient. With a world of internet, where everything is fast and easy to access, you need to make your website as accessible as possible.

Here are a few of the basics of availability and accessibility:

• Uptime: Make sure that your website is not down or have any errors when loading it. Invest in a good hosting.
• Broken links: Make sure that there are no dead links. Users shouldn't land to a 404 page. A good practice is to redirect the user to a new page if the link is unreachable. 
• Website responsiveness: Make your website available for every screen and support different layouts according to the resolution.

A good example of good accessibility is Amazon. Their website is accessible from anywhere and they have no downtime whatsoever, mainly because they are a hosting company as well. But if you look more closely, their website is responsive in both desktop and tablet, which adapts when resizing. And for mobile, they have an Adaptive website, with a different and cleaner layout, more adapted to a small resolution. We'll see the difference between responsiveness and adaptiveness in one of the following chapters.
