what about 404s traffic ?

I have some domain that made website before.
Now I parked these domain to Parked.com then have lots 404s traffice from those domains.

I wonder to ask if these traffic was valued traffic??

Thanks.

 

ask once again.
thanks

 

Donny would be better to answer this, but as far as I can recall, it's legitimate traffic and get served an ad page. Try it for yourself.

 

Thanks,
Now I put it at Parked.com,
It seems that the RPM is so low

 

compared to what? what keyword? Again, you might be better to ask Donny in the Parked forum @ NamePros.
