How to make money by blogging

Start blogging

Word Press and Blogger are two popular programs used to create blogs. Both give you options to start a blog with free versions.

Define Your Goal

The next step is to define select a topic about what your blog should focus on. You need to set out with a definite set of blogging goals if you want to monetize your blog. Know what your passion is, as it becomes easy to write about topics that you are comfortable.

Secure a domain

Now set-up a free sub-domain from blogger or word press(I would recommend blogger for beginners). Or buy a premium domain from good host. Your domain name should resemble with your blog topic.

Name your Blog

Select a appropriate Title for your blog. Enable and write optimized meta description and keyword. This helps in better visibility to search engines thus driving more traffic to it.
Quality content is what matters and attracts readers the most. Post useful and relevant content that bring visitors in search of solution. Since, ‘writing’ is the most important part of the blog you need to be well versed in the art of encapsulating readers through your content. Give importance to sentence structure, grammar and attention to details such as anecdotes, punctuation and others as these things add more beauty to your writing. Customize your blog with appropriate themes to make it look better.

Start Advertising and Promotion

Sign up for Google AdSense or other AdSense alternatives. AdSense will place ads for goods and services that are relevant to your site's visitors, based on the content of your site. You get paid every time an ad appears on your site, or an ad is clicked on.

Promote your site 

Every time you post, every time you make a change, every time you change a period to an exclamation mark or correct "teh" to "the," let the world know via Twitter, Facebook, Tumblr, LinkedIn, and all the rest of the social media world. The key is to spread the word.
Use pinging service to ping your blog so that search engine will be notified that change.
Use Google Adwords for advertising your blog.
Build backlinks for your sites reputation.

Pay attention to your metrics

Find which ads work best, and do more ads and pages like those. Watch your blog statastics, use Google Analytics for it. Check for popular posts, countries, keywords and more time on page spended by unique visitors, always remember the longer they stay better for google ranking
By continually refining your process, each visit will be a higher value for revenue generation.
