5 min readUpdated August 2025

Domain Research helps you discover keyword opportunities by analyzing what keywords websites in your niche are ranking for. Perfect for competitive intelligence and finding content gaps in your market.

What is Domain Research?

Research Mode Overview

Domain Research discovers what keywords are associated with any domain through comprehensive analysis. This helps you understand the keyword landscape in your niche and find opportunities you might have missed.

What You Get

  • • Keywords associated with the domain's niche
  • • Search volume and CPC data
  • • Keyword difficulty scores
  • • Search intent classification
  • • Results sorted by relevance

What You Don't Get

  • • Specific ranking positions
  • • SERP weakness detection
  • • Domain scores or competitive analysis
  • • Individual SERP result data
  • • KeywordScore calculation
Key Difference: Unlike Competitor Research which shows specific rankings, Domain Research finds keywords thematically related to a domain's content and niche, regardless of ranking position.

How Domain Research Works

Research Process

1

Domain Analysis

The system analyzes the domain's content, structure, and niche classification

2

Keyword Discovery

Finds keywords thematically related to the domain's content and market

3

Relevance Sorting

Results are automatically sorted by relevance to the domain's niche

4

Data Enrichment

Each keyword includes volume, CPC, difficulty, and intent data

Domain Input Requirements

Supported Domain Formats

ClearSERP accepts various domain formats and automatically normalizes them for analysis.

Accepted Formats:

  • example.com → Normalized to example.com
  • www.example.com → Normalized to example.com
  • https://example.com → Normalized to example.com
  • https://www.example.com/path → Normalized to example.com
Important: Domain research analyzes the entire domain, not specific pages. Even if you enter a full URL, the analysis covers the whole domain's keyword landscape.

Sorting by Relevance

Automatic Relevance Sorting

Unlike other research modes, Domain Research results are automatically sorted by relevance to the target domain's niche. This cannot be changed as relevance sorting provides the most meaningful insights.

Why Relevance Sorting?

  • • Shows most thematically related keywords first
  • • Helps identify core niche opportunities
  • • Reveals content themes you might have missed
  • • Optimizes discovery of related market segments
Tip: If you need results sorted by volume or difficulty, use the table sorting controls after the research completes, or export to CSV for custom analysis.

Location & Language Settings

Geographic & Language Targeting

Language Selection

Choose the language for keyword discovery. This affects the keyword discovery process and ensures culturally relevant keyword variations are found.

Impact: Different languages may reveal different keyword opportunities even for the same domain, based on regional search patterns.

Location Targeting

Select the target country for search volume and CPC data. This affects the commercial value and search patterns associated with discovered keywords.

Example: A fitness domain might show "gym membership" keywords with higher volume in certain countries compared to others.

Available Filtering Options

Domain Research Filters

Domain Research supports most of the same filters as Keyword Research, helping you refine the discovered keywords to match your specific needs.

Content-Based Filters

Contains Filters

Include only keywords that contain specific terms, with "ANY" or "ALL" logic options.

Example: For a fitness domain, filter for keywords containing "workout" OR "exercise" to focus on activity-related opportunities.

Doesn't Contain Filters

Exclude keywords that contain specific terms you want to avoid.

Use case: Filter out brand names or competitor terms to focus on generic opportunities in the niche.

Metric-Based Filters

Search Volume

Filter by monthly search volume to find keywords with your desired traffic potential within the domain's niche.

Cost Per Click

Filter by estimated CPC to identify high-value commercial opportunities within the market.

Keyword Difficulty

Filter by difficulty score (0-100) to find keywords matching your competitive capability.

Search Intent Filters

Filter discovered keywords by search intent to align with your content strategy goals.

Intent Applications:

  • Informational: Blog content opportunities
  • Commercial: Product comparison pages
  • Transactional: Direct sales opportunities
  • Navigational: Brand awareness gaps

Strategy Benefits:

  • • Align content with user intent
  • • Identify content type opportunities
  • • Discover conversion-focused keywords
  • • Plan content funnel strategies

Understanding Your Results

What the Results Tell You

Included Data:

Keyword: Keywords thematically related to the domain
Search Volume: Average monthly searches
CPC: Estimated cost-per-click for ads
Difficulty: Ranking difficulty score (0-100)
Intent: Classified search intent
Relevance: Sorted by thematic relevance (highest first)

What's Missing:

Ranking Position: No position data for the domain
SERP Analysis: No weakness detection
Traffic Estimates: No actual traffic data
KeywordScore: Not calculated in research mode
Page-Level Data: Domain-level analysis only
Interpretation: High-relevance keywords at the top of your results represent core opportunities in the domain's niche. Lower-relevance keywords may represent adjacent markets or broader category opportunities.

Strategic Use Cases

Competitive Intelligence

Analyze Competitors:

  • • Research competitor domains in your niche
  • • Discover keyword themes they target
  • • Find content gaps in their strategy
  • • Identify shared market opportunities

Market Expansion:

  • • Analyze successful domains in adjacent niches
  • • Find crossover keyword opportunities
  • • Discover new audience segments
  • • Plan content diversification

Content Strategy Development

Niche Analysis Example:

Research authoritative domains in your space (like industry publications or leading competitors) to discover keyword themes that define your market, then create comprehensive content around high-relevance opportunities you're not yet targeting.

Partnership & Collaboration Research

Analyze potential partner domains to understand their keyword focus and find collaboration opportunities in shared market segments.

Tip: Look for domains with complementary (not competing) keyword themes to identify potential cross-promotion or content collaboration opportunities.

Every domain research session is automatically saved to your Research History, preserving all discovered keyword opportunities for future reference.
