Purpose: measure whether external SEO and AI-search work brings natural visitors, high-intent landing visits, and paid orders.

Baseline:

- key_landing_search_or_ai_source_visits_7d: 68
- article_count: 425
- articles_sitemap_urls: 426
- article_quality_audit: 426 article URLs, 426 unique, 0 duplicates, 0 non-200, 0 missing title, 0 missing description, 0 missing H1, 0 noindex in the 2026-07-05 lightweight audit.

Measurement windows:
- 24h
- 72h
- 7d

Metrics:
- search-source article visits
- AI/search-source key landing visits
- referrers from csdn.net, zhihu.com, github.com, gist.github.com, google, bing, baidu, chatgpt.com and other AI/search surfaces
- visits to /articles, /chatgpt-plus, /chatgpt-pro, /order-query, /cat/4, /item/10
- orders by traffic_source, traffic_label, traffic_landing, traffic_referer
- paid order count, unpaid order count, paid amount

Short-term success:
- A new external referrer appears in logs.
- A CSDN, Zhihu, GitHub, search, or AI visitor reaches a relevant article page.
- The visitor continues to /chatgpt-plus, /chatgpt-pro, /order-query, /cat/4, or /item/10.
- At least one order is created from an external/search/AI source.

Mid-term success:
- Search-source article visits move from around 32/week toward 100/week.
- Key landing search/AI-source visits move from around 68/week toward 150/week.
- Bing keeps or improves rankings for high-intent troubleshooting queries.
- Google site-index samples keep showing GPT membership, Pro price, Codex, no-overseas-card, and troubleshooting clusters.

Priority query samples:

Recommended action loop:
1. Publish one high-quality external item.
2. Submit changed site files with IndexNow when relevant.
3. Wait 24h before judging early traffic.
4. Compare logs with the same source, landing, and order fields.
5. If the channel sends high-intent visitors, write the next adjacent tutorial.
6. If the channel sends no traffic, improve the title/angle or switch platform.

Guardrails:
- Do not modify payment logic, order system, SKU/product IDs, auto-delivery logic, backend APIs, or database structure.
- Do not add hard-sell checkout links on CSDN or Zhihu.
- Do not generate low-value duplicate public pages.
