Start with indexation and duplicate metadata. Both are cheap to fix and both cap everything else.
Weighted towards the two that cap everything above them: a page that is not indexed cannot rank, and a duplicated title tells a search engine the page is not distinct.
It summarises where your site is visible by cluster, showing which clusters you own, which you are close on, and which you are absent from.
A keyword count tells you nothing. Cluster coverage tells you what you can act on.
Group your tracked queries into clusters by intent, then record your best position and total impressions for each.
Sort by impressions rather than by position. A cluster at eleven with four thousand impressions matters more than one at three with forty.
It will not tell you whether a cluster is worth owning. Some suit your business and some do not, and that is commercial judgement.
It also uses your own impression data, so clusters you have never appeared for are invisible to it.
The clusters at positions six to fifteen are the opportunity. They have proven demand and you are close enough that a content or metadata fix can move them.
Clusters where you are absent entirely are content gaps, which are slower and more expensive but sometimes necessary.
Impressions. Position without volume is vanity.
Usually the six-to-fifteen band with real impressions.
No.
Half an hour on your own figures, and an honest answer about the parts Treepie does not improve.
