Yeah, I've jumped 32 spots for a secondary keyword 'narration' - which is fairly competitive. That seems significant to me, but I'm keeping a cool head.

Good Idea, when the shaking stops you often end-up deeper than what the initial jump was...lol

I have seen the serps change though the top 5 positions are standard with no chnage at all, but i see wites below us, move by 10 positions up and down every now and then.
