You need to make sure your website passes the mobile friendly test.
Clearly that nearly everyone responding to one of your QR Codes is going to be using a mobile phone to do the scanning. It is therefore imperative that you make sure that the web page they go to when is mobile friendly. (It’s obvious but it doesn’t always happen!)
What does a mobile friendly test do?
Mobile friendly means a variety of different things. The situation is evolving as phones get smarter and as the speed of mobile networks increases. For example, mobile screens are now very high resolution and so good quality images are a must. At the same time, you don’t want to send people to a web page that takes ages to load and uses a lot of data. This is particularly so because many people pay for each megabyte they download.
Loading speed is also important because research shows that the longer a page takes to load, the more likely it is that the visitor will give up, go away and do something else.
