How do you think LookSmart, BuySellAds & AdMob?

LookSmart makes focus on pc advertisement network.

BuySellAds offers platform to buy or sell ad.

AdMob does moblie advertisement network.

How do you think of these?

Do you have any experience in using that.

Which one is better choice?

 

LookSmart is still in business? I personally think they are *&&^^&**(())

Years ago they offered lifetime placement then they pulled the plug and offered no refunds and tried to upsell their existing customer base.

 

Is it unuseful?

 

If your landing page / site is mobile customized - AdMob should be your choice.

 

I have experience of working with BuySellAds where we can buy and sell ads on our blogs. And I have been able to earn $200 plus every month showing BSA ads on blog

 

As for buysellads.com, I'm afraid of the traffic I buy is poor quality.

I select some sites at random and check the traffic of its by alexa.com.

Most of sites have low traffic, so I'm really afraid whether we can buy quality traffic or not and really make profit through these sites?
