One thing we all need to think about when we use the internet is the trail we leave behind. This is known as our digital footprint, although more often these days they are being referred to as digital tattoos, as footprints can be washed away whereas tattoos are that much more permanent.
A trail can build up as we visit website after website. It can begin when we start clicking on adverts or sign up for various things, or when we share information about ourselves on social media sites like twitter and Facebook. Once information is placed on the internet it can be very difficult to have it removed.
There are positive aspects to having a digital footprint as well as negative ones.
Here is a link which explains digital footprints in more detail, how to teach children about them and it also has further links to more information.
