To start a blog, identify a subject you’re passionate about and that you can use to build an audience. Assign a name to your blog that is unique, and that tells people and Google what it’s about. Choose a host for your blog (WordPress is a popular one) and register the domain name (which should be highly descriptive of your blog’s subject matter). Choose a template or have your blog site designed to visually support your purpose. Write and publish blog posts, share them to gain followers, engage with those followers, and use your blog posts to augment your online marketing strategy.
