At her age she needs to go almost every hour. So make sure you take her out every hour on the hour. She should have some signs of impending elimination like circling, wandering away from you, sniffing the ground...etc. As soon as she does any of the above, scoop her up and put her outside to the spot you want her to go, and when she does, praise her enormously. If she doesn't go immediately, wait her out for 15 minutes or more to make sure she really doesn't need to go. If you don't give her enough time, she might pee as soon as you bring her back in the house, which is what you don't want.
While she's in the house, she needs 100% supervision. Many people let their puppies free roaming in the house and then wonder why they're peeing everywhere.
If you cannot supervise her, she needs to be in a crate. The crate needs to be small enough (or partitioned) so that she cannot pee in one corner and lie down in the other corner.
Finally, clean up all her previous spots very well with an enzymatic cleaner like Nature's Miracle. It's the only way to completely get rid of the smell. Bleach, household cleaners, vinegar, ammonia...etc. will NOT work. You might not smell it anymore but she will, and she will go again and again in the same spots.
