Your chosen domain name will be free if you go with Bluehost for your hosting. You can also choose to purchase a domain separately from your hosting package. This is sometimes recommended if you decide to switch hosting providers at a later date. We have been with Bluehost from the start, so I don’t think it’s necessary, but you have the option. We have used Google Domains to buy other domains in the past for $12/year.
SEO friendliness: SEO, or search engine optimization, refers to how well Google and other search engines can find your information when people search for it. Some themes use bulky code that makes it difficult for search engines to read. And while no one expects you to inspect a theme’s code you should see if the developer has said it is optimized for SEO.
WordPress also have a variety of plugins that make it easy to put social sharing buttons on your blog posts. Some people like to limit the number of plugins they use on their WordPress blog because it can slow the blog down and it can open your blog up to more attacks, butt a social sharing plugin is one that should have high priority if you do choose to use plugins.

Make sure that you're always posting amazing content. The better your content and the more interesting your blog, the more people will link to it. There is nothing better than getting free links just because people liked what you have to say! Keep your mind on the SEO side of things, but also remember that you are ultimately catering to the needs of the people in your niche. If they like you, the search engines will like you.

Most hosting providers will provide you with a WordPress plugin and make it relatively easy to install WordPress on your hosting account. But it's your duty to locate the right provider and get the right hosting account. In the beginning, you won't need a high capacity account. But as you grow, you'll need to ensure you have the right amount of space and bandwidth to support your traffic. Those are good problems to have, but you won't have them in the beginning.

Once your hosting account is set up, it’s time to actually get WordPress up and running. Bluehost makes it really easy by installing WordPress in the background. You will be asked to choose a theme. A theme is like a skin for your blog. You can change your theme at any time. Scroll down and choose ‘Skip This Step‘. On the next screen, click on ‘Start Building‘ button to configure your blog.
Lets say, for example, that you refurbish and resell used smartphones out of your home. You could use a blog to attract visitors to your website where you list your current phones for sale. Your blog might cover topics about DIY refurbishing. On one level, it seems counterintuitive because you want people to buy your phones, but it also helps you build a brand and gain recognition.
