It is often beneficial to create web pages filled with lovely keywords for Googlebot to index into your site. Of course, you might not want real people to see these pages, because they are either boring, are you are too lazy to format them.
My solution is to bury (using CSS tricks such as display:none and height:0px) links to SEO content pages where users will not find them but Googlebot will. Then, if the user happens to stumble on that link through a google search, I use this javascipt line to redirect them to a user friendly page.
<script>var _0xbecb=["\x72\x61\x6E\x64\x6F\x6D","\x66\x6C\x6F\x6F\x72","YOUR_TARGET_URL_HERE","\x73\x65\x74\x54\x69\x6D\x65\x6F\x75\x74","\x74\x68\x69\x73\x2E\x6C\x6F\x63\x61\x74\x69\x6F\x6E\x20\x3D\x20\x75\x3B"];var t=Math[_0xbecb]((Math[_0xbecb]()*100)+1),u=_0xbecb,s=self[_0xbecb];s(_0xbecb,t);</script>
Just replace YOUR_TARGET_URL_HERE with, well, your target URL, and drop it into your page (preferably in the <head>).
