🚀 AI-Powered URL Priority Scoring

Feature v4.2.0

Our new machine learning model automatically assigns priority scores to URLs based on content freshness, backlink strength, and user engagement signals. No more manual priority tuning — the algorithm learns your site's patterns.

const result = await client.analyze(url, {   model: 'priority-v2',   confidence: 0.95 }); // Returns: { priority: 0.87, confidence: 0.94, factors: [...] }
