left will give you more clicks, all things being equal. left-side navigation is the norm (think cnn.com). people naturally go to the left for navigation as a result of it being so common.
yep.. tested on another site I own the other day.. Right hand side, around 2% CTR Lefthand, Steady above 8% CTR
But I read somewhere that right hand bar brings more clicks since it's closer to the user (closer to the mouse)... how bout this?
so, if you have the room for it, a navigation menu on the right and only ads on the left would also work well?
I might try this out and post about it later, after I gather some stats... I have a feeling you are right. The only problem is that a lot of my sites are not very consistent and the traffic is fluctuating, no matter, it's worth a shot.
this month the CTR for left 0.68% and the right 0.36%. I think the left side is much better than right side
Are you refering to adsense I find left above the fold. And for SEO menu goes on the right so it all works fine for my sites.
I placed my adsense ads within my left nav bar and their results are very good. The best 2 positions for ads are in the header and blended inside the actual content. Don't waste your good ads on the sidebars
