Google isn't the one with the info. The actual websites have all the information. Not all of the websites presented on google are reliable... I suggest you go to these two websites. I trust them with my life for the most part. Bettysplendens.com and bettatalk.com Both have really good articles, and I would suggest that you read everything about spawning on those two websites if you haven't already.
Talking with experienced breeders will help boatloads! You can ask them what has worked for them, and what hasn't! Well, good luck getting all your research done with, and good luck in general :D
