This is where the SEO and the Content specialist
can work collaboratively on a single piece of content.
Should the content creator have the topic, the seo can do the keyword research, and structure a set of LSI terms, keywords and H1-H4 tags for the article.
By doing this the seo and content creator are both getting value for the other and hopefully ranking the content higher in the serps.
