I have seen many shore fisherman and women sitting on shore fishing or trying to get their snags out. When watching them I notice how many times they got snagged up when reeling their lines in. They have to remember that when the reeling back their lines most often they are dragging on the bottom just waiting for the first snag to grab them.
Remember this simple step when your going to reel in your line.
Snap the rod tip up and keep it up reeling fast keeping the hook of the bottom. This will help cut down the number of snags you get.
