As the image below illustrates - a website can not solely exist for the desktop experience but must also thrive on mobiles and tablets - taking advantage of modern swipe gestures and native browser and navigation.
Your web designer should create a fast loading website as well as a properly coded one. Correctly coded websites will have SEO at their core. On top of this, a correctly coded website will be lite on images and heavy in the code department.
At the end of the day, your website isn't about just getting a stack of information across - it's about conveying your brand and company in an aesthetically pleasing way. Therefore, we design websites that are very enjoyable.
