Wordpress Question: Is this even POSSIBLE?
 

Is there a plugin or system where your WP blog's theme refreshes to a random new theme whenever a NEW visitor loads a page/post? Obviously, the theme won't refresh to a new one until the visitor's cookie expires. Fresh new theme with each page/post load might make the site look like an online version of a Carlos Castaneda wet dream.

I'm asking because bounce rate is fast becoming a larger issue and maybe finding the most traffic friendly theme would shave a few points off BR. Obviously, BR is more a function of content quality/the amount of thematic similarity between the referring keyword and actual post the traffic lands on/and a list of other variables. See BR thoughts on http://twitter.com/#!/askmr5dollar

Stupid idea. Would put unnecessary server load on your site.

Concentrate more on developing a decent theme that does not look like it has been outsourced and decent relevant content.

of course it's possible, everything is possible

I can understand the concern regarding server load but experience has shown me that theme choice impacts ad clicks as well as content consumption levels. A poster did raise a good point regarding server resources so maybe make the alternating themes lighter?

Anything is possible, but why?

I might help but you would need a dedicated server just to run a site like this,

possible? yes, it's possible. And if you use light gfx (or no gfx at all) themes the server load won't be noticeable, but the problem I see is you'll confuse the hell out of your visitors, they'll think they've been tricked and redirected to a different site. Instead of that, try working colors and elements position. Sadly, there's no much you can do on a regular blog in terms of shapes, but try to use rounded corners at least, they've a noticeable CTR difference over square shapes

See above. Trying to find the best converting theme for a particular blend of traffic sources. Plus, I suspect bounce rate is going to be bigger factor in SERP analysis in the future (unless crowdsourcing gets a higher priority at Google). See my thoughts on this here.

i have a plugin you may like, its a theme rotator

:2 cents: especially on the part about confusing your visitors. might even increase your bounce rate.

maybe do lite changes....like (not sure if it's adult) randomizing the background image with a different babe on each page change. less load, change is subtle but still interesting and not making the surfer think he hit a whole different site

ya random headers is a good idea. or change the background depending on the sponsor, with repeating bgs

I agree that it might be confusing during the testing phase. Maybe have the theme switching done on a COOKIE basis. Also, add some sort of popup/entry notification regarding the theme testing so people don't flip their wigs.

good idea
