Comparing yourself against five competitors at once gives you an average, and you cannot act on an average.
The new head to head tab narrows it to one. Pick a competitor and you get the keywords you both rank on with the winner marked on each, the keywords they hold that you do not target at all, and the ones where you are alone, which are worth defending more than they look.
It is the view to open before rewriting a subtitle, because it tells you exactly which words you are contesting and which ones are free.
Head to head is in Competitors Analysis, next to the overview tabs.
