The Highest Rank in Search filter allows you to narrow down your results based on how many search terms were matched in a post, rather than its literal page position.
Here is how to interpret the numbers when filtering:
Lower Numbers (e.g., 1 or 2): Indicate fewer matched search terms. The post triggered fewer keyword matches.
Higher Numbers: Indicate broader keyword coverage. A higher number means the post matched with multiple search terms, which often points to higher overall relevance or a higher risk profile, depending on your use case.
Note: Use the From / To ranges to target posts based on their keyword density and match volume.
