Blogging is an art. It depends on a lot of things. Here are some included.
1. The topic/domain
this is not the domain name, it's about areas you'll focus on your blogs. So to find the best topics and areas for your blog, go ahead and follow Google trends on Twitter. You'll know a lot about what's trending. Then afterward, keep an eye on trending topics on Facebook and Twitter to get more heads. And use your own knowledge and skills to explain the topic.
2. Using a good blogging tool
There are many blogging tools available, most famous ones are WordPress and Blogger. You can give a tey to both as they both are free and then decide on one. WordPress is more scalable and customizable in future and you can get that done with freelancer developers anytime in future.
3. Get good images to support your blogs
use free image search like https://search.creativecommons.org or unsplash.com, pexels.com for getting good images. Even Flickr website has cc images search. Remember to give credits, sources to images you use. It's a good blogging etiquette.
4. Server and domain name
Choose a trendy and nice short blog name until you're spending heavy on marketing it which you must not if you're a novice blogger and have a business model. You can use http://www.shopify.com/tools/bus... to generate names with domain name availability. Choose a good server from. Godaddy or Hostgator. They perform equally well on WordPress.
5. Making people know
Use sharing tools, attach share plug-ins to your blog. Initially, ask friends and known ones to share your blog, read your blog, and invite people. This is the best way to get an understanding of whether you're good at what you're doing and ask feedback, suggestions and improve. You can market your blog for 1$ per day on Facebook to target people, who may recognize and follow your blog.
Create a page for your blog on Facebook, Twitter, and Instagram. Each article you write, share it on Facebook, Twitter, and Instagram all at once. And most importantly, keep replying and thanking people for likes, comments, and follows.
"All the best"
