How to guide puppy where to potty?

Hey all,

I'm looking some advice for my 11 weeks Cavapoo X puppy. She's a great wee thing now we've got her used to her crate, and we're slowly working on the biting with toys and a baseball style strike system (first strike redirect to toy, second redirect again and make a bit of a scene to show you didn't like it and third put her in her play pen and ignore until she calms a bit) which is going well but we're struggling on how to get the potty training done.

We've set up a few puppy pads in her crates play pen and at the back door for any emergencies. If she's in her pen she'll know to use them and occasionally use the back door if in the kitchen with us. When she's running wild in the house though she will go on any hard floor from bedrooms, kitchen, living room or bathroom. No rhyme or reason. We've tried not to punish this and guide her to the pad and associating it with the word potty, she doesn't go outside no matter how long we play, stand still etc. but I think that will start to come next weekend when we can start taking her out walks now she's just had her 2nd vac.

Just in and around the house, how do we start redirecting her to the pad. When I notice she's about to go I do lift her onto it but she gets excited and follows me off it again wanting to play etc.
