All tanks have to cycle when first set up. The nitrifying bacteria must become established and multiply according to the level of ammonia and then nitrite. This takes time, normally from 2 to 6 or 8 weeks.
"Seeding" the tank with existing live bacteria from filter media, substrate, wood or rock from an established tank, etc., simply "jumpstarts" the process. The advantage is less chance of "new tank syndrome" as it is called, when fish are exposed to high ammonia and then nitrite.
