## What it does

This skill queries SIF Amazon keyword competition metrics. It counts products across organic listings, Sponsored Products, video ads, brand campaigns, and editorial recommendations. A core metric is the supply-demand ratio, calculated by dividing total search results by monthly search volume. Lower values signal weaker competition.

Requests run via `python scripts/sif_keyword_overview.py` and are cached locally for 24 hours. The tool saves full JSON responses under `<cwd>/linkfox/<YYYY-MM-DD>/<session>/data/`. Execution halts immediately if the environment variable `LINKFOX_AGENT_API_KEY` or `LINKFOXAGENT_API_KEY` is missing.

The API covers 13 Amazon locales, defaulting to the US store. Queries for non-English marketplaces like Germany or Japan must be translated into the respective local language prior to lookup.

# 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

| Field | API Name | Description |
|-------|----------|-------------|
| Keyword | keyword | The queried keyword text |
| Keyword Popularity Rank | keywordPopularityRank | Monthly search volume rank among all keywords (lower = more popular) |
| Estimated Weekly Search Volume | estimatedWeeklySearchVolume | Estimated weekly search count on Amazon |
| Supply-Demand Ratio | supplyDemandRatio | Product count / monthly search volume (lower = less competition) |
| Total Search Result Products | totalSearchResultProductCount | Total products shown under this keyword (organic + ads + recommendations) |
| Natural Search Products | naturalSearchProductCount | Products in organic search results (excluding ads) |
| Sponsored Products (SP) Count | sponsoredProductsCount | Products running Sponsored Products ads |
| Brand Ad Products | brandAdProductCount | Products running Brand Ads |
```
