The search terms report is the most honest document in your marketing. It is the list of what people actually typed before they clicked your ad and cost you money. Not the keywords someone chose. The searches that actually happened. Fifteen minutes.
The second group is small and the negative list is long and recent. The account is being worked weekly. This is what good looks like.
The second group is large and the negative list is short or old. The account is on autopilot. The fix costs nothing: every wasted search you found goes on the negative list, and someone repeats this exercise every week. Ask whoever runs the account what they added last week. It is the one question that cannot be answered with a screenshot.
Most searches are "cannot tell." The campaign is set to match too broadly and is buying searches only loosely related to what you do. That is a structural fix, not a weekly one.
Your ad account is mostly defined by what it refuses to bid on. Read the search terms once and you will know what it has been saying yes to on your behalf, and whether anyone has been saying no.
