Even though running ads and promoting affiliate products are common ways to make money from a blog, you can also sell ad space on your blog and make money along with adsense and Amazon. Your blog can become advertising space for other businesses. You can sell advertising space on header, footer, sidebar, or even inside the post. You can even publish a sponsored post for advertiser. You will be able to sell advertising space only when you have a lot of traffic. A lot of advertising markets want at least 30k monthly traffic.
