Write content and promote your blog

The next step is to figure out what content you need to make for your new blog and the best practices you should follow. Whether your blog is to be composed primarily of words, photos, graphics, audio, video, etc. – the content will be the bait that draws your crowd. Few will come just to see your new site. Without great content, even the most well-designed, tightly-structured blogs will ultimately fail. The framework of the web is code – but the attraction of the web is the content found there.
Do keyword research & use tools to understand what's trending & build your content around the trending stories.
