Linkfox Sif Keyword Overview

SIF Keyword Overview

This skill guides you on how to query and analyze keyword-level competition data on Amazon, helping sellers assess market competitiveness and supply-demand dynamics for specific keywords.

Core Concepts

The SIF Keyword Overview tool provides a comprehensive snapshot of competition metrics for a given keyword on Amazon. It returns the number of competing products across different placement types (organic, sponsored, video ads, brand ads, etc.), estimated weekly search volume, keyword popularity ranking, and the supply-demand ratio.

Supply-demand ratio: Calculated as total search result product count / monthly search volume. A lower ratio indicates less competition and greater opportunity. This is a key metric for identifying blue-ocean keywords.

Keyword popularity ranking: Represents where this keyword ranks among all keywords on the marketplace by monthly search volume. A smaller number means higher search popularity (rank 1 is the most popular). When a user says "ranking improved," it means the numeric value decreased; "ranking dropped" means the value increased.

Data Fields

Supported Marketplaces

13 marketplaces: US (United States), UK (United Kingdom), DE (Germany), CA (Canada), JP (Japan), FR (France), ES (Spain), IT (Italy), MX (Mexico), AU (Australia), AE (United Arab Emirates), BR (Brazil), SA (Saudi Arabia).

Default marketplace is US. Use US when the user does not specify a marketplace. Codes outside this list will be rejected by the API pattern.

Important: The keyword parameter should ideally be in the language of the target marketplace. For example, use German keywords for DE, Japanese for JP, etc. If the user provides keywords in a different language, translate them to the marketplace's local language before querying.

调用方式

• API 端点：POST /sif/keywordOverview（完整参数/响应/错误码见 references/api.md）
• Python 脚本：python scripts/sif_keyword_overview.py '<JSON 参数>' [--inline]
• 成本约束：本工具会消耗算力；同一会话同一参数组合默认只调用一次，脚本带 24h 本地缓存。失败/空结果不得自动换关键词、翻页或改邮编连续试探；需要继续检索时先向用户说明会产生额外消耗。

输出策略（脚本默认行为）：

• 始终将完整响应写入 <cwd>/linkfox/<YYYY-MM-DD>/<session>/data/linkfox-sif-keyword-overview-<timestamp>.json（<cwd> 为脚本执行时的工作目录，在 Claude Code 里即当前项目目录；<session> 取自环境变量 SESSION_ID，按用户任务自动聚合；禁止写入 /tmp，当前目录不可写则报错）
• 响应体 ≤ 8 KB：落盘后把完整 JSON 打印到 stdout
• 响应体 > 8 KB：落盘后 stdout 只输出摘要（顶层字段、常见计数如 total/costToken、最大列表字段的长度 + 前 3 条样本）
• 加 --inline 强制全量打印到 stdout（同样落盘）

读数据建议：先看摘要判断是否足够；需要具体字段时优先用 jq或ConvertFrom-Json 从保存的 json 文件按需抽取，避免整份 JSON 进入上下文。

解决认证和算力问题

发生以下异常情况时，采用 references/onboarding.md 引导解决问题：

异常情况

• 未配置API Key：环境变量未配置 LINKFOX_AGENT_API_KEY，也未配置 LINKFOXAGENT_API_KEY。
• 响应401或402状态码
• 响应提示算力或余额不足：消息含"算力余额不足/计费不足/余额不足/quota exceeded/insufficient balance/套餐到期/需充值/请充值"，或类似含义的内容。

Parameter Guide

1. keyword (required): The search keyword to analyze. Should be translated to the target marketplace's language for best results. Maximum length: 1000 characters.
2. country (optional): The Amazon marketplace code. Defaults to US. See Supported Marketplaces above for valid codes.
3. last7d (optional, boolean, default true): Use the latest 7 days. When false, the API uses startDate/endDate.
4. startDate (optional, yyyy-MM-dd): Start date for a custom window. Takes effect when last7d=false.
5. endDate (optional, yyyy-MM-dd): End date paired with startDate.

Usage Examples

1. Basic keyword competition check Query: "How competitive is the keyword 'wireless charger' on Amazon US?"

{"keyword": "wireless charger", "country": "US"}

2. Check competition in a non-US marketplace Query: "How many competitors are there for 'Handyhulle' on Amazon Germany?"

{"keyword": "Handyhulle", "country": "DE"}

3. Supply-demand analysis for product research Query: "What's the supply-demand ratio for 'yoga mat' in the US?"

{"keyword": "yoga mat", "country": "US"}

4. Advertising competition assessment Query: "How many sellers are running ads on 'dog leash' in the UK?"

{"keyword": "dog leash", "country": "UK"}

5. Multi-marketplace comparison (multiple calls) Query: "Compare the competition for 'bluetooth speaker' across US, UK, and DE"

• Call 1: {"keyword": "bluetooth speaker", "country": "US"}
• Call 2: {"keyword": "bluetooth speaker", "country": "UK"}
• Call 3: {"keyword": "Bluetooth Lautsprecher", "country": "DE"}

6. Specific date range Query: "Competition for 'yoga mat' between 2026-03-08 and 2026-03-14"

{"keyword": "yoga mat", "country": "US", "last7d": false, "startDate": "2026-03-08", "endDate": "2026-03-14"}

Display Rules

1. Present data clearly: Show query results in a well-structured table format. Include all relevant metrics the user asked about.
2. Highlight key metrics: When showing results, emphasize the supply-demand ratio, keyword popularity rank, and total product count as these are the most actionable metrics.
3. Ranking clarification: When displaying keyword popularity rank, remind users that lower values mean higher search popularity.
4. Supply-demand interpretation: When showing the supply-demand ratio, provide context: values below 1 suggest high demand relative to supply (opportunity); values above 5 suggest a saturated market.
5. Ad competition breakdown: When users ask about advertising competition, break down the total paid advertising count into its components (SP, Brand, Video) for a more detailed view.
