If you have a company website then it is worth spending some time analysing the stats. Some companies use their own analytics package that is attached to their hosting or you may wish to use Google analytics which offers a user friendly comprehensive analytics program that is free to use.
When looking through your stats you may be surprised as to how many visitors view your website on a mobile or tablet device. More and more people own smart devices such as phones and tablets and are using them to browse the web and make purchases online. This information can be vital as you can then check to see what it is they are viewing and if it is showing all the information you want it to.
Checking your site regularly on these devices will allow you to quickly notice any issues where content is not displayed correctly or missing entirely. If you do have this issue you may notice that the bounce rate is higher or returning customers levels are lower on the mobile devices.
Be sure to correct any issues that you have and when new content is added or structural changes are made to the site, that these are replicated on the mobile version.
