Should I add more Ads?

I've got one ad block on the right side of most pages in my website, which is earning me a fair amount, considering I'm new to AdSense. My question is, should I choose to add another ad, where would be the best place to put it.

My website is greenzinemagazine.com

I really want to make sure visitors are not annoyed at all by ads, so out-of-the-way would be best.

What do you reckon?

 

Well if it's producing good click through rate + giving you an average expected cpc for each click (based on your niche), then I would just leave it as per it is.

 

You already on the right track, visitor come to your website to get news or some things not an ads.

 

No, just focus on advertising your website not craming it full of ads.

 

Decide what is more important... impressing visitors or making a quick profit.

 

It won't hurt to add one more ad on the right. Maybe a text ad will still look good on it. Your site looks very nice and it's very neat. Good job!
