The superconducting quantum interference device (SQUID) magnetometer is one of the most sensitive experimental techniques to magnetically characterize samples with high sensitivity. Here we present a detailed discussion of possible artifacts and pitfalls characteristic for commercial SQUID magnetometers. This includes intrinsic artifacts which stem from the inherent design of the magnetometer as well as potential issues due to the user. We provide some guidelines on how to avoid and correct these, which is of particular importance when the proper magnetization of nanoscale objects will be established in cases where its response is dwarfed by that of the substrate it comes with, a situation frequently found in the field of nanomagnetism.
