Having a simple and easy to use website will increase your sales. Part of this is making sure your site changes to fit the device your customer is using. Some of our customers have had their sales increase by as much as 40% when they have converted to a responsive website.
This is very important as it can have a huge effect on your marketing and business!
An old mobile site would redirect the customer to a totally different site with a simpler layout and menu than your desktop website. From the customers' perspective this is frustrating as they would be taken to another url (eg. mobile.tyranny.com.au or tyranny.com.au/mobilesite.) and lose the page and content they were looking for as they were on a completely different page.
A responsive site doesn't go to another url, it all stays the same! The only thing that changes is the style and design which we shrink to fit onto a mobile device, tablet or other monitor size.
The benefit of this is the customer always gets to the content they searched for - no funny business!
