Stalkers vary considerably in the types and frequency of stalking tactics.
Although stalking tactics and frequencies vary widely, several tactics appear to be common across cases of partner stalking, as noted in the table below.
Cyber-stalking can be defined as "the use of the Internet, e-mail, or other electronic communications devices to stalk another person"
 whereas the use of technology is more broadly defined as "the host of tools the stalker can use (now and in the future) to commit their crime," such as GPS and cameras in addition to the use of the Internet.
The following table summarizes a number of types of technology that can be used to stalk someone.
