I would agree, right sidebars get ignored. Place it in the left sidebar so it looks like navigation links. Looking at your site, you have changed it, but you've got 2 adsense ads next to each other in the left, it looks a bit weird, I would experiment as to what looks more appealing to the users.
yes, i do know that it's strange to put 2 ads next to each other. but i do it for not wasting the space. as an user's experience, what's your guys opinions?
come back to give a conclusion. i change the placement of my ads. one in the top-left of blog post, which is the high ctr place. another one at the bottom-left of blog post. you should take a look my autos blog. now, i earn almost 500$ in 20days. that is really great. wish my check next month.
