## 0. Verdict

SEO verdict: `Conditional Go`

Go 条件：Subnautica2Maps 可以继续进入 PRD / copy / design / implementation，但首版必须以真实 interactive map + route helper 为核心，不能退化成普通攻略站或薄 SEO 页面。

主要理由：

1. `subnautica 2 map` SERP 已经明确是 tool-seeking / interactive-map intent；用户要地图、坐标、筛选、marker detail、路线，不是长文。
2. 当前 SERP Top 3-5 有强站和强工具：IGN、Game8、MapGenie、GamesDB/Steam。新站只有靠“current position → route helper + source/confidence/version transparency + mobile-first”才有可进入空间。
3. Early Access 更新频繁，SEO 成败取决于数据可信度和更新机制；没有真实 marker/source/last verified 的页面必须 noindex。
4. IP/品牌风险高，`Subnautica` 品牌词不可伪装官方；每个核心模板必须有 fan-made / no-affiliation 信号。

不可上线条件：

- 没有可操作地图，只做 landing page。
- 复制 MapGenie/GamesDB/Game8/IGN 地图、marker、截图、图标或文案。
- sitemap 放入 placeholder、薄详情页、未验证 marker、搜索结果页。
- 页面承诺 “official / complete / all locations” 但无数据覆盖证据。
- analytics 只有脚本，没有真实事件收数证据。

## 1. Inputs and evidence boundary

本文件只读取 clean rerun Brief v0：

- `/root/.hermes/kanban/boards/site-factory/workspaces/t_7f12127a/reports/site-pipeline/site-rerun-subnautica2maps-20260520-clean/subnautica2maps/01-brief-v0.md`

本轮重新使用 web search / extract 获取 SERP 与竞品页面证据。未读取、未复用旧 PRD、旧设计、旧 seed data、旧 dist、旧 repo。

Live keyword volume / CPC / KD：未验证。上游已说明 DataForSEO 401，本任务不编造搜索量。

## 2. Search intent and keyword strategy

### Primary keyword

`subnautica 2 map`

Intent: tool-seeking / interactive map / resource locator。

用户真实任务：

- open a Subnautica 2 map now
- search resource / POI / blueprint / supply crate
- check coordinates and depth
- filter marker categories
- set current position
- get direction / distance / route hint
- use on mobile while playing
- save found/collected locally

首屏 SEO 承诺必须是产品承诺，不是内容承诺：

- Good: “A fan-made Subnautica 2 interactive map with resource search, coordinates, depth, and route hints from your current position.”
- Bad: “The ultimate complete official Subnautica 2 map guide.”

### P0 target keyword cluster

| Cluster | Primary query | Intent | Landing page | Index policy |
|---|---|---|---|---|
| Map head term | subnautica 2 map | open map / find locations | `/` | index when map preview/tool exists |
| Interactive map | subnautica 2 interactive map | full map tool | `/map` | index when map fully usable |
| Resource location | subnautica 2 silver location | find specific resource | `/resources/silver` | index only with confirmed marker list + route tips |
| Resource location | subnautica 2 copper location | find specific resource | `/resources/copper` | same |
| Resource location | subnautica 2 sulfur location | find specific resource | `/resources/sulfur` | same |
| POI | subnautica 2 black box locations | find POI / collectible | `/locations/black-boxes` or detail pages | index only with verified POIs |
| Coordinates | subnautica 2 coordinates | learn coordinate usage | `/guides/how-to-find-coordinates` | index |
| In-game map question | does subnautica 2 have a map | answer + tool CTA | `/guides/does-subnautica-2-have-a-map` | index |
| Biome | subnautica 2 coral gardens map | biome navigation | `/biomes/coral-gardens` | index with resource/POI/depth data |
| Biome | subnautica 2 karakorum map | biome navigation | `/biomes/karakorum` | index with resource/POI/depth data |

### P1/P2 keyword expansion

P1:

- `subnautica 2 gold location`
- `subnautica 2 lithium location`
- `subnautica 2 lead location`
- `subnautica 2 quartz location`
- `subnautica 2 data box locations`
- `subnautica 2 supply crate locations`
- `subnautica 2 camp one location`
- `subnautica 2 old habitat location`
- `subnautica 2 lifepod location`

P2:

- individual blueprint / fragment pages
- wildlife / plant pages
- update-specific pages after Early Access patches
- route pages only if real shareable route URLs exist and are not doorway pages

Avoid / deprioritize:

- `subnautica 2 official map` — high IP risk, avoid official wording.
- `subnautica 2 complete map` — only use after coverage evidence exists.
- broad `subnautica map` — old game / Below Zero mixed intent.
- scraped “all locations” pages without unique data — spam / thin risk.

## 3. SERP Top 3-5 scan

Query scanned: `subnautica 2 map` and supporting map/resource queries.

### SERP snapshot

| Position observed | Result | URL | SERP signal |
|---:|---|---|---|
| 1 | Steam Community — Useful Interactive Map for Subnautica 2 | `https://steamcommunity.com/app/1962700/discussions/0/844006106470597118/` | Community discovery thread. Mentions GamesDB map and MapGenie; users actively look for interactive maps and route help. |
| 2 | IGN — Subnautica 2 Interactive Map | `https://www.ign.com/wikis/subnautica-2/Subnautica_2_Interactive_Map:_All_Locations,_Resources,_Supply_Crates,_Black_Boxes,_and_More` | Strong media/domain authority + interactive map + resource/supply crate/black box framing. |
| 3 | Game8 — Interactive Map and All Locations | `https://game8.co/games/Subnautica-2/archives/599258` | Strong guide site with map, coordinates, depth, regions, login progress push. |
| 4 | MapGenie — Subnautica 2 Interactive Map | `https://mapgenie.io/subnautica-2/maps/world` | Strong dedicated map product, filters, progress, notes, embed, pro upsell. |
| 5 | MapGenie game hub | `https://mapgenie.io/subnautica-2` | Brand/site cluster result; reinforces MapGenie’s map authority. |
| discovered via Steam / direct extraction | GamesDB — Subnautica 2 Interactive Map | `https://gamesdb.gg/subnautica-2/map` | Important product competitor; route-from-current-position is a direct differentiator/standard to match. |

### Competitor capability breakdown

| Competitor | Strength | Weakness / gap we can attack | Minimum to match |
|---|---|---|---|
| IGN | Authority, guide hub, “all locations/resources/supply crates/black boxes” framing, rich internal guide network | Large-site guide wrapper; may not optimize for route-from-current-position or source/confidence transparency | map embed, resource/POI filters, guide hub, short answer blocks, strong internal links |
| Game8 | Coordinates, depth, POI tables, Early Access version notice, region/biome structure, progress-save via account | Login pressure; page can be heavy; comments/community updates not always source-normalized | coordinates/depth/notes/region/version for each marker; update notice; local progress alternative |
| MapGenie | Dedicated interactive map UX, many categories, progress tracker, notes/bookmark, map embed, pro upgrade | Ads/pro prompts; less content depth per marker; may be less transparent about source/confidence | pan/zoom, category filters, search, progress, marker detail, mobile usable |
| GamesDB | Marker categories, current-position/direction route framing from Steam description, resource/POI/blueprint/wildlife/plants coverage | Extracted content exposes little text/SEO; source/confidence and detail depth unclear | route helper, marker categories, search/filter, resource/POI/blueprint coverage |
| Steam/Reddit/YouTube community results | Shows demand and distribution paths; users share map links and route needs | Not durable owned SEO surface | cold-start channel, UGC feedback source, not primary SEO landing |

### SERP conclusion

The market is not empty. A thin “Subnautica 2 map” landing page has low chance.

Viable wedge:

- faster mobile-first map
- current-position route helper as primary UX
- marker detail with coordinates/depth/version/confidence/source
- local progress without account
- honest fan-made branding
- noindex discipline for weak data

## 4. Competitive minimum

Subnautica2Maps must not ship as “SEO complete” unless these are working and QA-verifiable:

1. Map baseline
   - pan/zoom map
   - self-made schematic/vector/coordinate-grid base
   - visible markers
   - search box
   - category filters
   - result count
   - mobile map + sheet/sidebar UX

2. Marker detail baseline
   - name
   - type/subtype
   - coordinates
   - depth
   - region/biome
   - description/notes
   - route_note

   - source_type
   - confidence

3. Route helper baseline

   - failed/invalid coordinate state handled

4. Local progress baseline

   - no login required in P0

5. SEO baseline
   - `/`, `/map`, resource/biome/guide pages have unique title/meta/H1
   - indexable pages have 800+ words when they are content-heavy pages; map/tool pages may have shorter body only if the tool itself delivers clear unique value and includes answer blocks, FAQ, source/update sections
   - canonical self-reference
   - sitemap includes only real indexable pages
   - robots does not block core JS/CSS/images
   - all images/icons have alt or aria-label where applicable

6. GEO/AEO baseline
   - answer-first blocks
   - definition blocks
   - source/update/confidence blocks
   - FAQ
   - BreadcrumbList + WebApplication + FAQPage where appropriate
   - item/detail schema only when content is real and source-backed

7. Legal baseline
   - visible “fan-made / not affiliated” in footer and relevant templates
   - no official logo/key art as site identity
   - DMCA/contact path
   - Privacy/Terms before launch

## 5. Interaction baseline

These are acceptance tests for product, SEO, QA, and analytics. If users cannot complete these tasks, SEO indexability should be blocked.

### P0 user tasks

## 7. Index / noindex / sitemap policy

### Indexable requirements

A page may be indexed only when all conditions are true:

1. Has unique search intent.
2. Has real user task value.
3. Has unique title/meta/H1.
4. Has self-canonical clean URL.
5. Has no `noindex`.
6. Has source/update/confidence where data is factual.
7. Has internal links from nav/hub/map/detail pages.
8. Is present in sitemap only after QA passes.
9. Does not copy official/competitor data/assets.
10. Is not just a query/filter state.

### Noindex by default

- `/map?resource=...`
- `/map?filter=...`
- `/search?...`
- user progress/local state pages
- unverified community marker previews
- empty marker detail pages
- placeholder/coming soon pages
- individual marker pages with description < 300 chars and no standalone task
- route result URLs unless share route feature becomes a real product and each URL has unique value
- tag/filter/category pages with no unique content

### Sitemap policy

Include:

- `/`
- `/map`
- validated resource pages
- validated biome pages
- high-value POI/location pages
- guide pages with complete answers
- update/changelog page if real

Exclude:

- query URLs
- noindex pages
- thin pages
- unverified marker pages
- search results
- local/user state pages

Canonical rules:

- `/map?resource=silver` canonical → `/resources/silver` when the resource page exists and is stronger.
- `/map?filter=resources` canonical → `/map`.
- detail page canonical → clean detail URL.
- duplicated POI aliases canonical → primary slug.

Image/video rules:

- All images need descriptive alt text.
- Map canvas/SVG must provide accessible labels/list fallback for important markers.
- Heavy videos must not load on `/map`; use lazy placeholder on guide/resource pages.
- OG image should be self-made and include fan-made positioning, not official art.
- YouTube embeds must include source attribution and fallback text.

## 12. Analytics / event plan

Implementation must prove real ingestion, not just script presence.

### Universal P0 events

| Event | Trigger | Required properties |
|---|---|---|
| `pageview` | page load | path, referrer, device_type |
| `hero_cta_click` | click map/tool CTA | cta_id, source_page |
| `tool_start` | first meaningful map/search/route interaction | tool_name, source_page |
| `tool_result` | route/search returns usable output | tool_name, result_count/success |

### Map/data-site P0 events

| Event | Trigger | Required properties |
|---|---|---|
| `map_search` | search submitted | keyword, result_count |
| `marker_open` | marker detail opened | marker_id, marker_type, source_context |
| `filter_apply` | filter selected | filter_type, filter_value, result_count |
| `detail_open` | detail page/panel opened | detail_type, slug |
| `position_set` | current position accepted | coordinate_format, success |

## 13. Legal / policy boundary for SEO templates

Mandatory language:

- “Fan-made Subnautica 2 map.”
- “Not affiliated with Unknown Worlds, Krafton, or the Subnautica team.”
- “Marker data may change during Early Access; check version and confidence labels.”

Mandatory pages/blocks:

- footer disclaimer
- About / legal disclaimer
- Contact / DMCA
- Privacy Policy
- Terms
- update/version page or block

SEO copy prohibitions:

- `official`
- `approved`
- `partner`
- `complete` unless proven
- `all locations` unless coverage audit supports it
- copied official lore/screenshot-heavy pages

Domain/brand risk:

- `subnautica2maps` contains branded term. If domain is already fixed, use strong fan-made language on every template and avoid official-looking design.
- If domain is not fixed, prefer a less official-looking brand/domain while still targeting keywords in page copy.

## 14. Technical SEO acceptance checklist

Before launch / index submission:

- [ ] `/robots.txt` exists and does not block core pages/resources.
- [ ] `/sitemap.xml` exists and includes only approved indexable URLs.
- [ ] Each indexable page has self-canonical.
- [ ] No indexable page has `noindex`.
- [ ] No noindex page appears in sitemap.
- [ ] Unique title per page, default 40-60 chars where feasible.
- [ ] Unique meta description per page, 70-160 chars.
- [ ] One H1 per page.
- [ ] H2/H3 structure covers task sections.
- [ ] Indexable content pages have ≥800 words or strong tool value with supporting blocks.
- [ ] All images/icons have alt/aria fallback.
- [ ] OG/Twitter tags exist for core pages.
- [ ] Breadcrumb visible and schema-valid.

- [ ] Core JS/CSS/images return 200 and are crawlable.
- [ ] Map tool has accessible non-canvas marker list fallback.
- [ ] SEO audit script blocks build/deploy if Title/Meta/H1/canonical/noindex/sitemap/robots/alt/OG/schema fail.

## 15. SEO audit script requirements for 墨界

Add a build/deploy gate script before production release. Minimum checks:

- title exists and is unique
- meta description exists and is unique
- canonical exists and self-references for indexable pages
- H1 count equals 1
- H2 count meets template baseline
- H3 count for content templates
- word count threshold for content pages
- primary keyword density around 2.5%-3.6% when natural; do not force on tool UI
- no `noindex` on indexable URLs
- sitemap includes indexable URLs
- sitemap excludes noindex URLs
- robots.txt reachable and not blocking assets
- image alt / aria labels
- OG/Twitter meta
- schema JSON-LD parseable and type-valid
- internal link reachability from hub/nav

Failure must block release.

## 16. Next assignee input

### For 墨策 / PRD

- Product positioning: fan-made interactive map + resource locator + route helper.
- MVP must include map/search/filter/detail/current-position route/local progress.
- Do not accept a PRD that describes only content pages.
- PRD must specify marker schema, data update workflow, index/noindex rules, analytics evidence, legal language.

### For 墨笔 / copy

- Write around player tasks: find resources, check coordinates/depth, route from current position, track progress.
- Use answer-first blocks on every guide/resource/biome page.
- Avoid official/complete/all-locations claims unless verified.
- Every data page needs source/update/confidence copy.

### For 墨影 / design

- Mobile-first map + bottom sheet/sidebar.
- Route helper must be visually prominent.
- Fan-made disclaimer visible but not disruptive.
- Design must not mimic official branding/key art.
- Design required states: search results, filter selected, marker detail, position set, route result, local progress, no results, low confidence.

### For 墨界 / 墨枢

- Self-made map base and marker icons.
- Static/edge-friendly implementation.
- Client-side search/filter first.
- Local progress in browser storage.
- Route calculation with coordinate validation.
- Verified analytics event ingestion.
- Add SEO audit script as release gate.

### For 墨盾

- Review branded domain/trademark risk.
- Approve fan-made/no-affiliation language.
- Block official logo/key art and copied competitor/official assets/data.
- Require Contact/DMCA/Privacy/Terms.

### For 墨账

- Do not design P0 around subscription.
- Allow free core map/search/filter/route.
- Consider donation/sponsor/light ads only after usage proof.
- Later Pro only for cross-device sync, advanced notes, ad-free, creator export.

## 17. Residual risks

1. Live keyword volume/CPC/KD unverified due upstream DataForSEO 401.
2. SERP is already competitive; thin site will fail.
3. Branded domain/IP risk remains high until compliance approval.
4. Marker data source and maintenance owner not locked.
5. Early Access updates can invalidate marker data quickly.
6. Route helper feasibility depends on coordinate model and map base.
7. Mobile performance risk with map + marker count.
8. If sitemap includes thin/placeholder pages, index quality will degrade.
