How Can I Explain The Google Dance To Clients Without Looking Like I’m Covering A Major Drop In Rankings?

In episode 175 of Semantic Mastery’s weekly Hump Day Hangouts, one participant asked how you can convey the message on Google Dance to clients without having to look like you’re covering a major drop in rankings.

The exact question was:

I read Marco’s article on the Google Dance and I know I have to make sure clients understand it as well. But when I say amidst a big drop in rankings, I fear I will look like I’m covering for dropping rankings. How can I convey the message to avoid that?
