Use only clickable links. At time of this writing, to the best of our knowledge, only Web Crawler allows redirects. This works on some but not all search engines. You really should follow this advice as many sites are being banned from the engines for overuse of keywords, hidden word spamming, use of title tag stacking and other frowned upon methods. They do not work anymore.
Search engines are hard on the trail of spammers.
Please don't indulge.
