Once a client sat down with me and wanted me to make a Web site about widgets. He showed me a competitor's site and it started making an annoying noise. I quickly learned that it somehow kept reloading/redirecting pages very rapidly, and this caused the client's laptop with Windows to make a clicking noise.
What could be the point of this seemingly pointless redirecting? The client thought it was some sort of SEO thing. I had no idea and still haven't. Ideas?
