I fish spinnerbaits in the spring, summer, and fall. It's all dependent on the type of cover that I have to fish on a particular day. My go to colors are white with gold blades, white/chartreuse with nickel blades, and white/chartreuse/blue with gold blades. I almost always throw Terminator spinnerbaits. On the rare occasion that I throw a different brand I have Strike King, Booya, and War Eagle to go to.
I like to target any tree lay downs in the water. If a lake has willow trees that's all the better. Other key areas for me are the edges of Lilly pad fields, reed edges, and grass areas. I'll work those areas generally with a steady retrieve at a moderate pace. If the bass are hitting well that day I know I can increase my speed a bit. Probably my least used retrieve style is slow rolling. If the fish are deeper I'll usually switch to a type of bait more appropriate for fishing deeper.
One other key area that I like to use a spinnerbait is at a creek mouth that comes into the lake. I like to pay particular attention to what I call the corners of the inlet.
I also see a lot of people who fish spinnerbaits too fast. If I see what I believe to be a good spot that should hold fish I'll generally makes several casts into that area before moving on. I've had many occasions where a fish will come out and hit the spinnerbait on the fourth or fifth cast on a piece of cover.
