Related Keywords in addition to NLP Topics in SEO Docs

Scalenut determines the topics via NLP. But this is only the view on the content of other documents in the SERPs. It lacks the view on the readers of these documents and their intentions. It would be important to know in addition for which keywords the documents of the top 30 also rank (related keywords) weighted by volume and frequency of overlap. This would give a view not only of content that is being written, but also of intentions that are being searched for.
