Should I add more AdSense ad or link units?

Hi,

I monetize my Cloud Business Review site with Adsense, and wondering whether I should add more ad / link units to it.

I don't want to clutter my site with plenty of ads and seek the right balance between ads and site presentation.

Any suggestions would be much appreciated!

Thanks

 

I do find only one Ad unit. It is better to add some more ad units.

 

May you can try link unit on top

 

@markov - I read somewhere that having less ad unit will increase competition, which equals to higher earning per click - true?

@plcshare - From my experience, link unit click through rate sucks...
