Focus entirely on on-page performance. Use Search Console to monitor keyword visibility and impressions. Track long-tail keyword growth over time. In GA4, analyze bounce rate, time on page, and click paths. Content must carry its weight without external validation. Monitor page speed, mobile usability, and core web vitals. Internal linking becomes critical. Check if these pages drive session depth. Track small wins like snippet appearances or AI Overview visibility. Zero backlinks doesn’t mean zero value. Measure by indexing speed, keyword spread, and dwell time. SEO without links is possible—but demands technical and content precision.
