hi. i having problem with my ads. every time i make an ad for my website and i enter the keyword i want to target, the ad stops. my website has content relevant to the keyword. if i enter any other keyword, the ad shows without problems, but if i add the keyword i want to target, it stops. there are other ads on the keyword i want, so keyword is eligible. does anyone know why my ad stops when i enter the keyword i want to target? i trying to figure this out for 3 weeks now with no luck. i have two questions about this: 1. why if i enter a random keyword the ad shows, but if i enter the keyword i want, the ad stops? 2. can i use broad match to get around this? let's say i want to target keyword "pizza", can i use keyword "pepperoni pizza" broad-match and if someone types "pizza" on search, will my ad show? i really need help with this
