Why VLink Outline DLN
Not another generic listicle template. A scientific SEO framework with locked distribution, variant pool, and intent classifier.
DLN framework
Locked distribution O:5 / C:4 / P:3 / R:4 / A:8 + Cross:1. Fits every buyer journey stage — never bottom-funnel-heavy.
Intent classifier
Rule-based VI + EN, $0 cost. Maps Transactional / Commercial / Informational / Local + dominant DLN stage. AI prompt is weighted by detected intent.
Variant pool
Every H2 has 3 phrasings. Visitor-seeded picker — same user gets stable outline, different users get different ones → Google never canonicalizes.
Multi-AI provider
Claude Sonnet 4.5 + OpenAI gpt-4o-mini. Primary + fallback chain — auto-retry on failure. ~$0.001 per outline.
Credits never expire
One-time purchase. Buy today, use a year from now. No hidden subscription, no auto-renewal.
Three export formats
HTML for Gutenberg/Elementor, Markdown for Notion/Obsidian, branded PDF for client deliverables.
PayPal-grade billing
PayPal Orders v2 + HMAC-verified webhooks. Idempotent grants — duplicate webhooks never double-credit. Refunds auto-revoke + email.
Transparent ledger
Every credit IN/OUT has its own row with running balance. CSV export for PayPal reconciliation. Full audit log.
Privacy-first
Only topic + industry label leave your site to the AI provider. No account, post content, or analytics shared. GDPR-friendly.
