domain-keywords

Keyword tracking, ranking, and opportunity scoring for SEO/SEM research

What it is for

domain-keywords: Keyword tracking, ranking, and opportunity scoring

Overview

This crate provides a comprehensive keyword research and tracking system for SEO/SEM analysis. It handles keyword management, ranking tracking across competitors, SERP feature detection, and opportunity scoring.

Layer

Domain - depends on: foundation-basemodels

Key Types

• Keyword - A keyword being tracked
• KeywordRanking - A ranking record for a keyword/competitor
• KeywordOpportunity - Computed opportunity score
• KeywordMarketMetrics - Per-keyword, per-location market data (seasonality)
• KeywordVolumeHistory - Time-series search-volume observations for a keyword
• KeywordIntent - Search intent classification
• KeywordStatus - Tracking status

Scoring System

Opportunity scores are calculated using:

• Volume score (30%): Based on monthly search volume
• Difficulty score (25%): Inverted ranking difficulty
• Competition score (25%): Based on competitor rankings
• Intent score (20%): Based on search intent type

Example

use domain_keywords::{
Keyword, KeywordRanking, KeywordIntent, KeywordStatus,
scoring::{calculate_opportunity, volume_score}
};

// Create a keyword
let keyword = Keyword::new(tenant_id, "plumber phoenix")
.with_search_volume(12_000)
.with_difficulty(45)
.with_intent(KeywordIntent::Commercial);

// Create a ranking
let ranking = KeywordRanking::new(keyword.id, competitor_id)
.with_rank(5)
.with_featured_snippet();

// Calculate opportunity
let opportunity = calculate_opportunity(&keyword, &ranking, None);
println!("Opportunity: {} ({})", opportunity.opportunity_score, opportunity.priority_tier);

No pub use re-exports: every item above is declared in this crate.

Boundary

Reaches into foundation.

Shares tier domain with 41 other crates: domain-agreements, domain-ai-report, domain-billing, domain-catalog, domain-classify, domain-comments, domain-competitive-intel, domain-contact, … (41 total).

_What this crate deliberately does NOT own is a judgment. No committed registry records one for it, so none is stated here._

Feature flags

No Cargo features are defined: every capability is unconditional, so no consumer can receive a half-wired crate.

Targets

Error model

No public error type was detected: no public item declares a type named *Error, and no public signature returns one.

Operational characteristics

No unsafe block, unsafe fn, unsafe impl or unsafe trait was found by the parser anywhere in this crate's source.

Configuration

No environment variable is read with a literal name anywhere in this crate. A variable whose key is computed at run time cannot be listed here, and is not claimed to be absent.

Related capabilities

1 workspace crate depends on this one: application-keywords.
