Read what your site already earns
Export ninety days of queries, sort by impressions, and group everything into five buckets by what the searcher wants.
You can point at each bucket and name the page that should serve it. Two buckets have no page, and you can say so without guessing.
The awkward part of unit one is discovering that your best page is not the one you would have chosen. That is the lesson. Search Console records what people typed, not what you meant to rank for.
