A rule for deciding which search terms deserve more ad spend right now versus which need a content fix first, driven by the SQP Funnel Stage Diagnostic (Thumbnail vs. Listing Problem) output for that term.
This turns the funnel diagnosis into an explicit spend/no-spend gate per search term, rather than treating an under-performing keyword as always meaning "spend more."
Essential Candy's Amazon Search Query Performance (SQP) Report showed generic, high-traffic terms like "peppermint" and "hard candy" capturing only ~0.05% of their total available search volume for those terms — despite ranking for them "feeling" like SEO success. Illustrates the gap between chasing broad/obvious keywords and actually capturing the volume behind more specific, lower-competition intent terms.
