Look at the list of recommended keywords from the SEO Writing Assistant. Why are some of these keywords highlighted green?

In Semrush's SEO Writing Assistant, keywords highlighted in green indicate that you have successfully incorporated them into the body of your content. This visual cue helps you track which recommended keywords you've already used, allowing you to focus on integrating the remaining ones for better SEO optimization. The tool aims to ensure comprehensive coverage of relevant terms within your text. While using keywords in headings and titles is also important for SEO, the green highlight specifically signifies their presence within the main copy, not exclusively in those structural elements. The highlighting doesn't inherently mean they are the "most relevant," but rather that they are present.
