Nowadays many people with very less traffic ie: less than 100 uniques per day are going for CPM and PPC ads. It is a wrong way as these all are for sites having atleast 1000 uniques. So keep in mind the only way to monetize your traffic or content is affiliate programs. Choose the best according to your country relevance of traffic. Affiliate programs are more targeted and you can have some payouts while ppc and cpm will never going to pay you until you reach their minimum payouts. So keep in mind again that affiliate programs can make a minimum payout in days instead of months. I am telling this from my experience. I had tried almost all ad programs available now. PPC and CPM ads are for site which provide any information reaying any matter. If your site is content oriented then you must use affiliate programs. I can help you with your blog/site Good luck
Thanks for advice. but some time if we own network of sites. then PPC also help. Affiliate program only give money when they get sales. but PPC is easy.
