wp_semrush_keyword_difficulty returns Semrush's 0–100 difficulty score for any phrase — the standard signal for how hard it will be to rank in the top 10. Each row costs 50 API units (Semrush's most expensive endpoint), so use it surgically after first shortlisting candidates with `wp_semrush_keyword_overview` or `wp_semrush_related_keywords`. Every response includes `_units_cost` so the AI can warn you before bulk runs.
