help with an adword campaing

hi, i need help about the duration of an adword campaing..

 

It's as long as you want. Set it for a day or a year.

 

There's no minimum or maximum. It's all custom to what you want.

 

the thing is... i want to make a test with 2 campaings to check out which one is the best working for me. so this test should it be for a long period? or just 1 or 2 days?

 

Set the time period as you like in adwords center. Or just prepay both campaigns with a certain amount and once the prepay balance is down to zero, your ads won't be shown anymore.
1 or 2 days probably won't show you anything since there is even a big different between weekdays and weekend days. I would think 2 weeks is more realistic.
Good Luck
