I am very new to internet marketing and planning to start with blogging. I am a devops engineer looking to earn some extra cash on the side with what I know. I am planning to create a blog meant for information in the devops field.
My questions are:
1. What should I focus on for now to grow the blog?
2. At what stage can I say I can monetize the blog?
3. What are the possible ways to monetize a blog meant for people in the IT industry?
4. Overall, is that niche a good idea?
