But i would like to say that at the basic level, you should promote only one site and if get best results for it then slowly try to promote the other sites to get more benefit. But then you need to manage all the things for all of your website so you need to be more focused to give your full performance.
promoting 3-4 website is good enough to get good traffic and rank on SERPs.
This is more true with a business or authority site. 5 sites still seem to be a good number for a publisher to promote. But that's on a part-time basis.
