One attractive feature of promoting digital information products is that the commissions tend to be higher than that of physical products; ranging anywhere from 10 percent to 50 percent or even higher. As an example, if someone is selling a digital information product for $500 with a 50 percent commission, you can earn $250 per sale. This is much higher than commissions on physical products due to the high profit margins.
If you can keep your readers engaged and actively reading your content and digesting it thoroughly, Google will take notice. Engagement, calculated through things like the average time spent reading your content, average session time, exit rate, bounce rate, and so on, is one of the primary components when ranking on Google's competitive Search Engine Results Pages (SERPs).

Number of pictures – Ordinarily, up to 1 GB of total storage, shared with Picasa Web. If you've upgraded to Google+, your photos will be stored in Google Photos, where you have 15 GB of storage space shared with Gmail and Drive. However, if one has signed up for Google+ account, images less than 16 megapixels (4920 x 3264)[33] would not be counted to this storage limit. For users not signed up for Google+, 800 x 800 pixels and below images would not be included in this storage space.
Define Your Ideal Readers. Once you’ve found your niche, you need to know who will be reading your blog. For example, we blog about living a meaningful life with less. Thus, our ideal readers are people who are interested in exploring minimalism so they can clear the path toward more meaningful lives. If you want to write about your newborn baby growing up, that’s wonderful: your ideal readers are probably your friends and family. If you want to write about restoring classic cars, that’s cool, too. Tailor your writing to your readers (whether it’s your family or local community or whoever else will read your blog).

So let me start out by answering your first question: where does the income come from? I go into this in greater detail in my How to Make Money from a Blog post, but it sounds like you’ve got the idea. My main source of income is through ads, but I also earn money through my books and courses, affiliate commissions, my Etsy store, and occasionally sponsored posts.
Help document travel, education and other life events – Sometimes, people start blogs to help document some kind of journey. That journey might be traveling to some far-off destination. That journey could also involve learning a musical instrument or a new language. It could also involve a life event such as getting married, divorced or fighting through a health scare.
Be aware that many blog hosting services only allow their proprietary contextual ad service, and may shut down your blog if you use one not made by the host company. If you are hosting your own blog, you should research contextual ad services and choose one that shows appropriate ads. Some allow pornography or other ads that may not be suitable for your blog.
Keep reading and listening and pick up inspiration. Stay up to date and deepen your knowledge about your niche. Read books and blogs about it. Listen to podcasts and watch videos. When you have new ideas flowing into your mind each week and month you’ll come with new stuff yourself. Or combine what you have learned. Or you can share your experience with what you learned from someone else.

Please Note: I am an affiliate of Bluehost. That means, I’ll get a commission every time someone uses one of my links to sign up for the service. However, I do believe that Bluehost is one of the best hosting companies out there, with one of the best customer service departments, which is crucial when you’re doing something technical like hosting a blog.
A blog itself isn't really a business—it's more of a platform for other income streams. Your content alone won't likely make you money. Instead, you'll have to get advertisers, sell services like consulting or speaking, use affiliate marketing to get a percentage of sales from links people click on your blog, or maybe offer products like ebooks or premium content to actually generate income. ProBlogger has an excellent post about these different ways you can make money.
In a version of the service called Blogger in Draft,[14] new features are tested before being released to all users. New features are discussed in the service's official blog.[15] In September 2009, Google introduced new features into Blogger as part of its tenth-anniversary celebration. The features included a new interface for post editing, improved image handling, Raw HTML Conversion, and other Google Docs-based implementations, including:
Selling private ads can come in the form of banners, buttons, or links. You can even make money writing sponsored posts where you write about or give a review of an advertiser’s product or service. Another option is to write an underwritten post or series, which is where you can write about any topic, but the advertiser pays for a “Brought to you by” mention in the content.
