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.
Some blogs are focused on getting paid to provide links to news articles, company stores, or other third party websites. The most financially successful of these range from the Drudge, a blog composed almost entirely of conservative-leaning news links, to Smashing Magazine, a site that provides advice and product reviews to help software developers.[5][6]
If you’re passionate about something, it will show in your content. Readers will be able to see your genuineness and will be attracted to that. This is probably the most important thing you will learn about blogging. You can try everything in the world and use every tool known to man to be successful, but if you’re not genuine, people will see right through it.

Include keywords in important places. Include them in your blog post title, the large "headers" introducing a new section, the first few sentences of your post, and in links. Change your settings so each blog post's URL includes the title of the post, not the date it was posted. Try to make these as descriptive as possible to raise your ranking in search results and attract the right audience.

Sometimes I think we just need permission to do the things we love without having to make a living at it. So I'm giving you permission. I'm telling you it's fine for you to have a blog that gives you an outlet for your creativity, allows you to talk about things that are important to you and lets you stay connected to friends and family. You don't have to try to monetize your joy.
Quality content is content that people can engage with and find useful. Your content should help readers and bring them value. Your blog needs to have interesting, helpful content that people would be willing to recommend or share with their friends. The format, structure, layout (and, of course, the writing itself) will all determine the quality of your blog.
Success in every facet of life is based on who you know and not what you know 🙂 The secret is to start connecting with more people, if you build your network wide enough you’ll meet someone who can help you, no matter what it is that you are trying to achieve. Some meet these influential people more quickly by complete luck of the draw, others need to keep plugging along longer. The system works either way, and whether or not it works better for others is irrelevant, all systems in life work better for some than others.
