Yes, on the Rocketspark system, you have the ability to embed some third-party add ons to create a popup notification based on your website visitors' locations. The scenario where you may want this is when you have several websites, one for each of the countries you serve, but you don't want your visitors from one country to visit the other country's website.
For example, if a business has a New Zealand and Australian website, you don't want Australian visitors visiting the New Zealand website and vice versa. This is where a popup can come in very handy on the Australian website stating for the visitor to instead visit their local website.
The best way to integrate this with your website is by using a plugin where you can install and set this up yourself. A provider that works well with Rocketspark is the GeoTargetly Geo Popup, however, there are many other different providers that will work and the above is just an example of an add-on. You can create a popup to display based on a visitor's location and you can even use it to redirect them to another website.
You will be given some code by the widget provider that can then be inserted into the head or body of a website in the Get Found (SEO) section of the dashboard: How do I add a tracking code or third party script tag to my website?
Once the code has been added you should be able to see the pop up appear when you are not logged into your dashboard.
