Article header section only contains the Primary Keyword - and remember, no "period" at the end

The first paragraph offers the Primary Keyword twice. Make sure to keep the content applicable to the topic, "human" and user-friendly to the reader.

In the second paragraph the Primary Keyword is only required once. Tier 2 Keywords may be sprinkled throughout the entire page while the focus is always kept to the Primary Keyword and Tier 1 Keyword.

The third paragraph and following paragraphs will contain the Primary Keyword once per paragraph. It's that simple!
