## 0. Verdict

SEO verdict: Conditional Go.

Primary keyword: `video compressor`.

可进入，但不是泛工具站打法。必须以“client-side-first / no-upload default / MP4 H.264 / target-size presets”作为硬定位，先打 P0 六页：`/`、`/mp4-compressor`、`/compress-video-for-discord`、`/compress-video-for-whatsapp`、`/compress-video-for-instagram`、`/privacy-video-compressor`。

上线前硬闸门：

1. 工具必须能完成至少一个真实 MP4/H.264 desktop Chrome 压缩流程。
2. 每个 P0 indexable 页面必须有独特工具入口或 preset deep-link，不能只是改标题。
3. 默认 no-upload 声明必须和实现一致；网络检查不能上传媒体文件。
4. 不得出现 forbidden claims：`unlimited`、`lossless`、`no quality loss`、`support all formats`、`official Discord/WhatsApp/Instagram compressor`。
5. SEO Copy Freeze 必须在设计前冻结：逐页 primary keyword、semantic keywords、target words、H1/H2/H3、final copy blocks、FAQ/schema、internal links。
6. 首版技术栈必须诚实写浏览器/移动端限制：best on desktop Chrome/Edge；Safari/iOS/mobile may be slower or unsupported。

## 1. Source data read

上游结论可用，不需要重开域名选择：

- Domain fixed: `videocompressor.online`.
- PRD verdict: `GO_WITH_CONSTRAINTS`.
- Search volume source: DataForSEO Google Ads Search Volume live, US/en, 2026-06-03.
- SERP source: DataForSEO Google Organic SERP live, US/en desktop depth 10 for `video compressor`, plus current web extraction cross-check.
- Primary keyword: `video compressor`, US monthly volume 90,500, KD 72.
- Best long-tail wedge: `mp4 compressor`, US monthly volume 12,100, KD 41; `compress video for Discord`, US monthly volume 1,300, KD 31.
- P0 product boundary: browser local compression, MP4/H.264 output first, Discord 10MB, WhatsApp 16MB, Email 25MB, Instagram resolution/quality guidance.

## 2. SERP read

### 2.1 Head SERP pressure

`video compressor` 是高量老词，不是新词红利。SERP 被大站压住：FreeConvert、Clideo、VEED、InVideo 等都有强域名、现成工具、长尾页面和编辑器/转换器套件。

但 Top 10 不是完全封闭：Rotato Tools、compress.addy.ie、8mb.video、Kommodo 等小/专工具能进入，说明“工作工具 + 清晰差异化 + 可完成任务”仍有空间。

### 2.2 可打入口

优先顺序：

1. `/mp4-compressor`：`mp4 compressor` KD 41，强任务、格式明确，最适合早期拿长尾。
2. `/compress-video-for-discord`：`compress video for Discord` KD 31，目标大小明确，能用 10MB preset 建立体验差异。
3. `/privacy-video-compressor`：对抗 upload-based incumbents，增强 GEO/AI citation 可引用性。
4. `/`：承接 head term，但首期不应以 head term 排名作为唯一成功标准。
5. `/compress-video-for-whatsapp`、`/compress-video-for-instagram`：低量但能补全 preset/use-case 矩阵，必须有真实设置和 caveats。

### 2.3 AIO / AI citation 风险

AI Overview / ChatGPT Search / Perplexity 很可能引用强域名、官方文档、或大型工具页。新站需要结构化、可引用、低夸张 copy：

- 每页首屏下方放 40–70 words Short answer block。
- 明确回答：Does this upload my video? What output format? How to hit Discord 10MB? Why did compression miss target size?
- 每页有 `Last updated`、browser support、format caveat、privacy caveat。
- 平台名只作 compatibility/share-context 描述，不写 official/endorsed。

## 3. Competitor UX baseline

### 3.1 Baseline table

| Competitor | SERP role | Tool interaction baseline | Strength | Gap we can attack | Must match / beat |
|---|---|---|---|---|---|
| FreeConvert `/video-compressor` | Head-term incumbent, large multi-tool site | Choose file from device/cloud/URL, max 1GB free, advanced compression methods: percentage of original size, CRF/quality, max bitrate, resize, H.264/H.265, batch/preset controls | Authority, broad format support, advanced settings, cloud imports | Upload privacy concern, config complexity, generic funnel | Simple file picker, target MB, resolution/quality, visible before/after size, H.264 compatibility explanation |
| VEED `/tools/video-compressor` | Brand/editor incumbent | Upload file, auto balance quality/size, manual quality/resolution/compression level, real-time file size estimates, then download or continue editing; free up to 1GB | Strong UX, editor upsell, social/email/website use cases | Heavy editor funnel, upload-based workflow, less privacy-first | Immediate compressor above fold, no editor distraction, local/no-upload proof, size estimates if feasible |
| Clideo `/compress-video` | Tool-suite incumbent + platform pages | Upload, set parameters/preset, estimate compression/output size, preview before saving, premium larger limits/no watermark, mobile-responsive | IA depth, mobile story, related guides/platform pages | Cloud upload, Premium limitations, app upsell | Preview/result card, estimated output, platform page template, FAQ around permanent quality tradeoff |
| Rotato Tools `/compress` | Direct local/privacy competitor | Drop file, browser/on-device FFmpeg, auto compression, compare original/compressed with slider, download; no signup/private | Strong privacy claim, simple UX, tool suite | Generic path under Rotato, fewer target-size/task pages, “no visible quality loss” risky | No-upload trust strip, local processing copy, better target-size presets, platform pages, avoid absolute quality claims |
| Kommodo `/tools/compress` | Direct WebCodecs/browser competitor | Select/drag video, choose resolution and quality, compress with progress, download MP4/H.264; claims WebCodecs/GPU, no upload, no limits with memory caveat | Closest positioning, WebCodecs specificity, email/social use cases | Claims “no limits/unlimited” risk; no dedicated target-size platform matrix in reviewed page | WebCodecs-first copy, H.264 output, resolution presets, browser support table, target-size presets, conservative file-cap copy |
| 8mb.video | Discord/target-size niche | Upload server-side, compress just under 8MB, server status, deletion after 20 min or first download, Discord disclaimer | Strong niche memory, target-size promise, deletion copy | Old 8MB framing, narrow Discord use, server upload | 10MB Discord preset, deletion not needed in local mode, platform disclaimer, target-miss honesty |
| Autocompressor | Target-size power tool | Upload media or URL, 2 GiB input limit, choose target size, output format, compression level, job link/status/download, completed files deleted after 24h | Target-size depth, Discord/Gmail fit, advanced codec choices | Complex UI, server upload, niche/technical | Custom MB + presets, simple quality-time choice, avoid overcomplex codec options in v0 |
| InVideo compressor | Editor platform funnel | Upload up to 800MB, choose compression quality, compress/download; links to many format/platform pages | SEO long-tail matrix, no-signup funnel | Upload-based, editor upsell, broad claims | Build route matrix early, but each route needs unique preset/tool entry |
| Adobe Express video resizer | Adjacent resize competitor | Upload up to 1GB/1h, pick destination size, resize, continue editing | Brand trust, destination presets, mobile/editor ecosystem | Resizer not compressor; upload/editor heavy | Instagram page should learn from destination presets but stay compressor/resolution-focused |

### 3.2 Interaction baseline — what v0 must let users do

P0 interactive acceptance baseline:

1. Open `/` and select a local MP4 file without creating account.
2. See privacy cue before selecting file: “processed locally in supported browsers; no upload by default”.
3. See parsed input facts when possible: size, type, duration, resolution.
4. Pick a target preset: Discord 10MB, WhatsApp 16MB, Email 25MB, Instagram recommended settings, or custom MB.
5. Pick resolution: keep original, 1080p, 720p, 480p.
6. Pick quality: High, Balanced, Smallest.
7. Start compression and see progress, elapsed time, “keep this tab open”, and cancel.
8. Complete and see before size, output size, ratio, preset used, target met/missed status, download button.
9. If target is missed, show actual size and next actions: lower resolution, increase target MB, choose Smallest, trim video.
10. If unsupported/failed, show reason bucket: unsupported browser, unsupported codec, memory, timeout, mux error, user cancelled, unknown.
11. On mobile, warn that local compression may be slow and desktop Chrome/Edge is recommended.
12. In default local mode, browser network log must not show media upload, thumbnail upload, filename upload, or raw metadata upload.

### 3.3 UX anti-patterns to avoid

- “Upload your video” wording as the default CTA. Use “Choose video” / “Select local video” unless server mode exists.
- Compress button before target/preset clarity.
- Hiding target-missed output as success.
- Generic “Something went wrong” failures.
- Full editor detours before download.
- A platform page that says “for Discord” but does not preselect Discord 10MB.
- “No quality loss” / “lossless” copy in hero, FAQ, alt text, schema, or meta.

## 4. Route matrix

### 4.1 P0 pages

| Route | Priority | Index | Primary keyword | Intent | Above-fold tool behavior | Unique value | Target words | Density target |
|---|---|---|---|---|---|---|---:|---|
| `/` | P0 | index | video compressor | Compress video now | Default tool with all presets; no-upload trust strip visible | Head page: private browser compressor + target-size presets | 900–1,300 | primary + synonyms 2.5–3.3% natural |
| `/mp4-compressor` | P0 | index | mp4 compressor | Reduce MP4 file size online | Tool opens in MP4/H.264 mode; explains output MP4/H.264 + AAC | Format-specific guidance, H.264 compatibility, target MB | 850–1,150 | 2.5–3.4% |
| `/compress-video-for-discord` | P0 | index | compress video for Discord | Fit Discord upload/share limit | 10MB preset preselected; custom target available | Strongest long-tail, target-size outcome and target-miss recovery | 850–1,150 | 2.4–3.3% |
| `/compress-video-for-whatsapp` | P0 | index | compress video for WhatsApp | Fit WhatsApp sharing | 16MB preset preselected; explain quality/resolution tradeoff | Useful task page, careful platform copy | 800–1,050 | 2.2–3.1% |
| `/compress-video-for-instagram` | P0 | index | compress video for Instagram | Prepare upload quality/resolution | 1080p + Balanced recommended; no fake universal MB limit | Format/resolution guidance rather than strict size claim | 850–1,100 | 2.2–3.1% |
| `/privacy-video-compressor` | P0 | index | no upload video compressor | Find private/browser/local compressor | Tool CTA + local processing explanation; no upload proof points | Differentiation and AI citation page | 850–1,150 | 2.2–3.2% |

### 4.2 P1 pages

Only index after corresponding function/preset is real:

| Route | Primary keyword | Index condition | Notes |
|---|---|---|---|
| `/compress-video-to-10mb` | compress video to 10mb | Target-size algorithm works and target-missed UI exists | Can canonical to Discord page only if no unique copy; otherwise separate page |
| `/compress-video-to-25mb` | compress video to 25mb | Email 25MB preset works | Good email attachment intent |
| `/video-compressor-for-email` | video compressor for email | 25MB workflow tested | P1 likely useful for office/student ICP |
| `/reduce-video-file-size` | reduce video file size | Enough educational + tool content to avoid thin page | Can be an evergreen explainer/hub |
| `/mov-compressor` | mov compressor | MOV input verified across browsers | Noindex until tested |
| `/webm-compressor` | webm compressor | WebM input verified | Noindex until tested |
| `/video-resizer` | video resizer | Resize function exists as distinct feature | Do not create if only downscale inside compressor |

### 4.3 Noindex / redirect rules

- `/no-upload-video-compressor` → 308 to `/privacy-video-compressor` unless unique content is written.
- `/online-video-compressor` → 308 to `/` unless unique head page exists.
- `/free-video-compressor` → 308 to `/` unless pricing/free page has unique value.
- Unsupported format/platform placeholders: `noindex`, excluded from sitemap.
- Any page whose preset/tool behavior is not implemented: `noindex` until functional.

## 5. SEO-Copy Freeze contract

### 5.1 Global copy rules

Required on every P0 indexable page:

- Unique title 40–60 chars.
- Meta description 140–160 chars recommended; 70–160 acceptable if reason documented.
- One H1 only; H1 must match visible hero title.
- H2 count >= 3; H3 count >= 2 for homepage/tool/hub pages.
- Body content >= 800 words for indexable P0 SEO pages.
- Short answer block 40–70 words near top, visible, not hidden in FAQ only.
- FAQPage schema for FAQ section; BreadcrumbList on all non-home routes; WebApplication/SoftwareApplication on tool pages.
- Internal links: home ↔ all P0 pages; platform pages link to `/mp4-compressor` and `/privacy-video-compressor`; privacy page links back to tool pages.
- All images/icons with non-empty alt; decorative icons use empty alt only if semantically decorative in HTML, but SEO screenshots/OG need descriptive alt.

Forbidden terms in copy/schema/meta/alt:

- unlimited video compression
- lossless video compressor
- no quality loss
- supports all formats
- any video size
- official Discord compressor / official WhatsApp compressor / official Instagram compressor
- fastest video compressor online

Allowed safer phrasing:

- “No upload by default in supported browsers.”
- “Reduce file size with quality tradeoffs.”
- “P0 focuses on MP4/H.264 output.”
- “Large files depend on browser, device memory, codec, duration, and resolution.”
- “If the output misses your target, try 720p, a higher target size, or a shorter clip.”

## 6. Schema plan

### 6.1 Global schema

Required:

- `WebSite` on all pages.
- `Organization` or `Person/Organization` depending final brand policy; avoid fake company claims if no company page.
- `BreadcrumbList` on all non-home pages.
- `FAQPage` on every P0 page with visible FAQ copy matching page content.
- `WebApplication` or `SoftwareApplication` for tool pages.

Recommended WebApplication fields:

```json
{
  "@type": "WebApplication",
  "name": "VideoCompressor.online",
  "applicationCategory": "MultimediaApplication",
  "operatingSystem": "Web browser",
  "browserRequirements": "Best on desktop Chrome or Edge; support depends on browser video APIs and device memory.",
  "offers": {"@type":"Offer","price":"0","priceCurrency":"USD"}
}
```

Do not add unsupported claims in schema:

- `featureList: unlimited compression`
- `featureList: lossless compression`
- `fileFormat: all formats`
- official platform affiliation.

### 6.2 Page-specific schema notes

| Route | Schema | Notes |
|---|---|---|
| `/` | WebApplication + FAQPage + WebSite | FAQ must include privacy, target size, MP4 output, quality tradeoff, mobile/browser support |
| `/mp4-compressor` | WebApplication + FAQPage + BreadcrumbList | Mention MP4/H.264/AAC first; do not imply every codec works |
| `/compress-video-for-discord` | WebApplication + FAQPage + BreadcrumbList | Add platform disclaimer in visible copy, not schema affiliation |
| `/compress-video-for-whatsapp` | WebApplication + FAQPage + BreadcrumbList | 16MB guidance must be sourced/qualified; avoid official claim |
| `/compress-video-for-instagram` | WebApplication + FAQPage + BreadcrumbList | Focus on resolution/quality; no fake universal MB limit |
| `/privacy-video-compressor` | CreativeWork/Article + FAQPage + BreadcrumbList + WebApplication mention | Strongest AI citation page for no-upload explanation |

## 7. GEO / AEO block plan

Every P0 page should include these reusable blocks with route-specific wording:

1. Short answer block: 40–70 words, visible near top.
2. “Best settings” table: target size, resolution, quality, expected tradeoff.
3. “What happens in your browser” privacy block.
4. “If compression misses the target” troubleshooting list.
5. FAQ with direct answers, not marketing paragraphs.
6. Compatibility caveat: desktop Chrome/Edge best; Safari/iPhone/mobile caveat.
7. Last updated line: `Last updated: 2026-06-03` at launch; update after QA browser/file-cap evidence.

Suggested citation-ready facts:

- “P0 output is MP4/H.264 + AAC first.”
- “Default workflow processes locally in supported browsers; no upload by default.”
- “Target-size compression can miss the exact target depending on source video, duration, codec, and selected quality.”
- “For smaller output, lower resolution before making extreme quality cuts.”
- “Large video compression depends on device memory and browser support.”

## 8. Internal linking plan

Homepage:

- Links to all P0 pages in visible preset/use-case section.
- Footer links to `/privacy-video-compressor`, `/privacy`, `/terms`.

Format/platform pages:

- Top body link back to `/` using “online video compressor”.
- Contextual link to `/privacy-video-compressor` using “no-upload video compressor”.
- Platform pages cross-link only when helpful: Discord ↔ MP4; WhatsApp ↔ MP4; Instagram ↔ MP4 and privacy.

Privacy page:

- Links back to the homepage tool.
- Links to `/mp4-compressor` and platform pages as examples of local workflow.

Anchor rules:

- Use descriptive anchors: “compress MP4 videos”, “compress video for Discord”, “private video compressor”.
- Do not use “click here”.
- Do not overlink every keyword occurrence; 3–6 internal contextual links per page is enough.

## 9. Technical SEO gate for downstream frontend

Before deploy, add `seo:audit` and make deploy chain run:

`npm run build && npm run seo:audit && deploy`

Audit must fail deployment if any P0 indexable page violates:

- status 200 route exists.
- one self-referencing canonical.
- no `noindex` on P0 pages.
- unique title 40–60 chars.
- meta description unique, 70–160 chars, recommended 140–160.
- exactly one H1.
- H2 >= 3 and H3 >= 2 for P0 pages.
- body text >= 800 words for P0 indexable SEO pages.
- primary/synonym density roughly 2.5–3.6%; if lower, waiver with reason and semantic alternatives.
- all non-decorative images have non-empty alt.
- `og:title`, `og:description`, `og:url`, `twitter:card` present.
- `robots.txt` exists and does not block core resources.
- `sitemap.xml` contains all P0 indexable pages and excludes noindex/placeholder pages.
- JSON-LD validates and does not include unsupported claims.
- forbidden copy scanner passes across HTML/meta/schema/alt.

## 10. IP / brand / compliance constraints for SEO templates

1. Platform names are allowed for compatibility and use-case description only.
2. Add visible disclaimers on Discord/WhatsApp/Instagram pages: not affiliated, endorsed, or sponsored.
3. Do not use platform logos unless license/brand guideline approval is confirmed; plain text names are safer.
4. Do not claim official limits unless sourced and date-qualified. For Instagram, avoid exact universal MB limits.
5. Privacy claims must be implementation-backed; if any server upload mode appears later, split copy clearly by mode.
6. Analytics must not collect filename, local path, media content, thumbnail, or raw metadata.
7. If output target is missed, UI and copy must not imply success.
8. If ffmpeg.wasm/WebCodecs limitations are discovered, SEO copy must be updated before launch.

## 11. Next inputs for downstream agents

### For 墨笔 / Copy

Produce SEO-Copy Freeze final copy blocks for the six P0 pages using section outlines above. Each block must mark placement:

- `above_fold`
- `visible`
- `collapsible`
- `child_page`

Need final copy for:

- Hero headline/subhead.
- Short answer block.
- Best settings table.
- How it works.
- Browser support/limits.
- FAQ answers.
- Platform disclaimers.

### For 墨影 / Design

Design must produce content-fit matrix for all six P0 pages. It cannot silently remove SEO copy. Required states:

- empty
- file selected
- unsupported file
- ready
- processing
- success
- target missed
- failed
- mobile warning

### For 墨界 / Frontend

Need technical spike result before final SEO copy locks file-cap numbers:

- WebCodecs-only vs WebCodecs + ffmpeg.wasm fallback.
- MP4 muxing library.
- Tested browser matrix.
- Tested input size/duration/resolution caps.
- Whether target-size algorithm can reliably hit Discord 10MB / WhatsApp 16MB / Email 25MB.
- Network proof that default local mode does not upload media.

### For 墨测 / QA

QA must run real browser tasks, not just DOM/metadata checks:

- Desktop Chrome/Edge: compress one representative MP4/H.264 and download playable output.
- Mobile viewport 390/430px: file picker/preset/error copy usable.
- Network inspection: no media upload in default local mode.
- Target missed path: actual size and retry guidance visible.
- Unsupported file path: actionable reason shown.
- SEO audit: all P0 pages pass technical/content/schema gates.
