There are a lot of things you need to do to rank well for a web page but we would recommend first focusing on these three:
- Regular content that answers the questions people are asking relevant to your business eg. How do I get in to Olympic weightlifting? What are the benefits of weightlifting? Will I lose weight if I start weightlifting? Etc etc.
- A well optimised page (see Yoast software in WordPress with the green lights)
- Good quality links into the page (quality and relevance rather than quantity)
