Whether you call it by its scientific name of Glechoma hederacea, Creeping Charlie, Runaway Robin, Ground Ivy or any of its other common names (including #$%%$#@& *!) this invasive little member of the mint family is a pain in the posterior.
Because it can take root anywhere a node (where the leaves attach to the stem) touches the ground, it spreads rapidly and, because not all broadleaf herbicides affect it, once it gains a foothold in your lawn it can seem impossible to get rid of.
Creeping Charlie grows best where lawns are poorest so using good lawn keeping practices – reseeding bare or thin spots, mowing at the right height, etc. will help keep it at bay. Once established, however, you have to be really proactive to get rid of it and, even if you succeed, it will likely sneak over from your neighbors and try to re-establish itself.
Creeping Charlie's roots are shallow, so the plant is easily uprooted and small areas can be controlled by regular, thorough, hand-weeding; for larger areas you may want to consider an herbicide containing either Dicamba or triclopyr. Any time you choose to use an herbicide, be sure to read the label, understand the label, and follow the directions to the letter.
