On site Redirects

I'd like to write some content on my site that will show up in the SERPS, but when people visit the content, I want them to be immediately redirected to my main page instead of the content.

Im using wordpress.

How can I do this?

I think you can do it with a variation of any cloaking system existing (like wp_cloacker), it detects if your visitor is a bot (google/yahoo/whatever) or not and instead of just showing a different content you redirect to your target page.
