I've seen somewhere that you can randomize your LPs using a same link, for example, yoursite.com -> site1, yoursite.com -> site2, yoursite.com -> site3 etc. Anybody know the html code for this?
It is best done serverside and cannot be done with pure HTML Depending on if you are talking landing page or complete sites would dictate how best to do it (likewise if it is LP then if you want that person to see the same LP again next time or if they could visit your site 10 times in a few hours and see 10 different LPs)
You could just use a redirect script to make this happen. I currently use software that works very well i.e that it allows you to split test everything. Hope this helps.
