Before you create content, you should identify your site’s audience. These are the people you want to visit your site. For example, the audience for onadivabaseballcards.com include people who are interested in baseball cards. Once you identify your audience, you can create content that is useful and relevant to them.

You can use a powerful tool called Google Trends to explore trends and related keywords your audience might be searching. A search for “baseball” shows variations and related terms that people have searched in addition to “baseball”. You can see when and where these searches come from, along with search volume for different terms. It also shows interesting trends over time associated with search terms. Understanding related terms to your site’s content helps you to create more relevant content for your audience, leading to more people finding your site.
Gather a test audience
Once you have plans for your website written down, show your friends and family to gather feedback. Ask them what they think of your site as a potential visitor. You can also conduct surveys or usability tests. Ask insightful questions: What would they expect to find on your site? Is there missing information that they would find useful? Hearing what others have to say about your site can help you relate to your audience better.
Now that you’ve identified your audience, you can begin creating content with them in mind.
