Here’s a nice, very basic Google Analytics report which you might like to run regularly. It’s only a couple of clicks, and it’ll give you an idea of what devices people are using to access your website, and how that’s changing. Click on the image to see it more clearly.
Go to the main reporting screen, and set up the date range to be, for example, last month. Check the “compare to” box and select “previous year”.
On the left menu, click “Audience”, “Mobile” and “Overview”. Finally, I like to select the little bar chart icon for clarity, to get rid of all the default unwanted data.
And that’s it. You might see typically that your mobile traffic has gone from (say) 5% to 10% over the past year. If that’s the case, it’s a strong hint that your site really needs to look good on mobile devices, as if the encouragement from Google wasn’t enough.
If you’re just interested in a certain type of traffic, such as visitors from the UK, use segmentation: click on “All Sessions” and create a new segment (if you don’t already have one) for what you want. You’ll probably need to use “Advanced Conditions”.
And why not have the report emailed to you every month? Just click the “email” button at the top and fill in the details.
