can you stop robots from crawling the bottom part of a page?

can you stop robots from crawling the bottom part of a page?

like put in a no-crawl tag inside the body tags?

I was told not to have all my sites linked at bottom of the pages so I have done away with that but I’d like to have the links on the bottom of the page but not have the SE’s no I was linking the sites.

any ideas?

thanks
