Can anyone help me to monetize my blog?

I want to start to monetize my blog (blogger) but no use google ads are their any other good PPC, maybe something that can target video games. Also I'm already using Amazon.

Try CPA networks. Ad Center is the other big one but it's pretty worthless.

Adscend Media.

Depends totally on your traffic, trust me it's not easy to get even 500 unique visitors per day, with the kind of saturation in every field these days. Nothing is better than AdSense. Get real advertisers for your blog if not an adnetwork. BidVertiser, AdBrite and if you have really heavy traffic then try CPM Ads like Smowtion, TLV Media and the list goes on.

If you are concentrating on a certain product or topic and are good at selling or marketing, try ClickBank or any affiliate marketing there is a lot of $$ in there.
With a website with substantial amount of traffic you could earn from $100 - $500/day.
This cannot be achieved overnight at all!

If you want something that targets video games there is CPMstar, haven't used it yet so I'm not to sure about it but it is used on halolz so I'm pretty sure it's legit.
