I confine mine to a small area - like the kitchen. Put the food and water in one place, near his bed - potty pads go as far away as possible. They don't want to "go" anywhere near their bed and food. Keep him in that area until he "goes". Praise him and give him treats. He'll catch on quickly. Use several pads at first and gradually take them away until you're down to one.
Or you can use a crate and take him from the crate immediately to a pad (confined area - like the shower) and leave him there until he goes.
The puppies I just sold were 11 weeks old and most of the time they would hit the potty pad. People were here looking at one of them when he ran down the hall to the potty pad, did his business and came running back.
That helped sell him I am sure.
