Every SEO-relevant project mapped. Status: live = deployed, partial = some live, spec = specced not built, existing = baseline.
Each subdomain owns a topical lane. Degree Board sits at the data center, seo-content-api is the publishing pipeline. Cross-links flow bidirectionally between initiatives but no URL duplication.
One user moves through 4 stages over 8–15 years. Each stage maps to a different initiative as the primary destination, but all initiatives cross-link so the user never leaves StudySmarter as their interest evolves.
Total ~1.15M pages new + rewritten. Pillar L (96 niche jobboards Hybrid scope) is now the largest single addition. Existing 700K talents jobboard not shown.
Combined organic-session forecast across all 6 subdomains. Existing baseline ~3M/mo, additional ~5.7M/mo from new + rewritten initiatives at base case M18 → ~8.7M total. Pillar I rewrite is the single biggest delta.
Combined revenue across affiliate (Pillar K, Studienfinanzierung, int'l Sperrkonto), lead-gen (Weiterbildung Apiron-forward, AZAV-Beratungstermin), and B2B (jobboard employer pipeline lift from int'l visa-sponsor cluster).
