SEO Keyword Research

When to Activate

Use this skill when planning content strategy, identifying new ranking opportunities, building topic clusters, analyzing competitors' organic strategy, or prioritizing which pages to create or optimize. This is the foundation of any organic growth strategy.

First Questions

1. What does the business do and who is the target audience?
2. What are the core products, services, or topics?
3. What is the site's current domain authority/strength? (determines feasible keyword difficulty)
4. What's the goal? (traffic, leads, sales, brand awareness)
5. What content already exists? (avoid cannibalization, find gaps)
6. Who are the top 3-5 organic competitors?

Search Intent Classification

Before targeting any keyword, classify its intent. Google rewards pages that match search intent — mismatched intent will never rank.

The Four Intent Types

Intent	Description	SERP Signals	Content Format
Informational	User wants to learn something	Blog posts, guides, wikis, knowledge panels, PAA boxes	How-to guides, explainers, lists
Navigational	User wants to find a specific site or page	Brand results dominate, site links	Homepage, specific product/brand page
Commercial Investigation	User is researching before a purchase	Comparison articles, review sites, "best of" lists	Comparison posts, reviews, buyer's guides
Transactional	User is ready to buy or take action	Product pages, pricing pages, shopping results, ads	Product pages, pricing pages, signup pages

Intent Identification Method

1. Google the keyword — What types of results does Google show?
2. Look at the top 5 results — Are they blog posts? Product pages? Landing pages?
3. Check SERP features — Shopping results = transactional. Featured snippets = informational.
4. Examine the language — "How to," "what is" = informational. "Best," "vs," "review" = commercial. "Buy," "pricing," "coupon" = transactional.

Intent Mapping to Funnel

Top of Funnel (Awareness)     → Informational intent
Middle of Funnel (Consideration) → Commercial investigation intent
Bottom of Funnel (Decision)    → Transactional intent

Keyword Difficulty Assessment

Not all keywords are worth targeting. Assess difficulty before committing resources.

Factors That Determine Difficulty

1. Domain Rating (DR) of top-ranking pages — If the top 10 are all DR 80+ sites, a DR 30 site will struggle
2. Backlink profiles of ranking pages — How many referring domains do the top results have?
3. Content quality of ranking pages — Can you create something meaningfully better?
4. SERP features — Featured snippets, PAA, and knowledge panels reduce organic CTR
5. Search intent alignment — If your page type doesn't match the intent, difficulty is effectively infinite

Difficulty Tiers (for a DR 30-50 site)

Keyword Difficulty (KD)	Feasibility	Strategy
KD 0-20	Target aggressively	Win with good content alone
KD 21-40	Good opportunities	Need solid content + some internal links
KD 41-60	Competitive	Need strong content + internal links + backlinks
KD 61-80	Very competitive	Need exceptional content + backlink campaign
KD 80+	Extremely difficult	Only target if you have DR 70+ or a unique angle

The Reality Check

For new or small sites (DR < 30):

• Focus on KD 0-30 keywords
• Target long-tail variations with lower competition
• Build topical authority in a niche before going after head terms
• A KD 10 keyword with 500 searches/month is more valuable than a KD 70 keyword with 10,000 searches/month that you'll never rank for

Search Volume Analysis

Understanding Search Volume

• Search volume is a monthly average, often 12-month trailing
• Volumes are rounded (100, 200, 500, 1K, 2K, 5K, 10K, etc.)
• Seasonal keywords have misleading averages — check trends
• Zero-volume keywords can still drive valuable traffic (long-tail, emerging terms)

Volume Thresholds by Strategy

Business Type	Minimum Volume Worth Targeting	Why
Local business	10-50/month	Small volume but high conversion intent
B2B SaaS	50-200/month	Low volume but high-value customers
B2B content marketing	200-1,000/month	Need enough volume to justify content investment
B2C / eCommerce	1,000+/month	Higher volume needed to drive meaningful traffic
Publisher / media	5,000+/month	Ad revenue model needs scale

Beyond Volume: Traffic Potential

A keyword's true traffic potential is often 3-10x its search volume because:

• A page ranking for "email marketing strategy" also ranks for "email marketing plan," "email strategy," and hundreds of long-tail variations
• Check what the top-ranking page for your keyword actually gets in total organic traffic (use Ahrefs/Semrush)
• Target the keyword that has the highest traffic potential, not just the highest individual search volume

Long-Tail Keyword Strategy

Long-tail keywords are longer, more specific phrases with lower volume but higher conversion rates and lower competition.

Finding Long-Tail Keywords

1. Google Autocomplete — Start typing your seed keyword and note suggestions
2. People Also Ask (PAA) — Questions Google surfaces in the SERP
3. Related Searches — At the bottom of the Google results page
4. Google Search Console — Queries your site already ranks for (positions 5-20 are optimization opportunities)
5. "Searches related to" on Reddit/Quora — Real questions from real people
6. Keyword tools — Filter by low KD + commercial or transactional intent
7. Customer support tickets and sales call transcripts — The exact language your customers use

Long-Tail Examples

Head Term (hard)	Long-Tail Variation (easier)	Intent
CRM software	best CRM for small law firms	Commercial
email marketing	how to write a welcome email sequence	Informational
project management	project management tool for remote teams under 10 people	Commercial
SEO	how to do keyword research for a new blog	Informational

Topic Cluster Model

Organize content into clusters around pillar topics. This builds topical authority and helps Google understand your content's breadth and depth.

Structure

                    [PILLAR PAGE]
                   /    |    |    \
            [Cluster] [Cluster] [Cluster] [Cluster]
               |         |         |         |
           [Sub-topic] [Sub-topic] [Sub-topic] [Sub-topic]

Building a Topic Cluster

1. Identify the pillar topic — A broad, high-volume keyword: "email marketing"
2. Map cluster pages — Subtopics that support the pillar: "email segmentation," "email automation," "email subject lines," "email deliverability"
3. Identify sub-topics — Even more specific pages under each cluster: "how to segment by purchase history," "welcome email sequence template"
4. Create the internal linking structure:
   • Pillar links to every cluster page
   • Every cluster page links back to the pillar
   • Cluster pages link to related cluster pages
   • Sub-topics link to their parent cluster page

Example Topic Cluster: "Content Marketing"

Pillar Page: The Complete Guide to Content Marketing (targets: "content marketing")

Cluster Pages:

• Content Marketing Strategy (targets: "content marketing strategy")
• Content Marketing ROI (targets: "content marketing ROI")
• Content Marketing Tools (targets: "best content marketing tools")
• Content Distribution (targets: "content distribution strategy")
• Content Calendar (targets: "content calendar template")

Sub-Topic Pages (under "Content Marketing Strategy"):

• How to Create a Content Brief (targets: "content brief template")
• Editorial Calendar Template (targets: "editorial calendar template")
• Content Marketing for B2B (targets: "B2B content marketing")
• Content Marketing for SaaS (targets: "SaaS content marketing strategy")

Keyword Mapping to Content

Map each keyword to a specific page to avoid cannibalization (multiple pages competing for the same keyword).

Keyword Map Template

Primary Keyword	Volume	KD	Intent	Page URL	Status	Priority
email marketing strategy	5,400	52	Informational	/blog/email-marketing-strategy/	Published	High
best email marketing tools	3,200	45	Commercial	/blog/best-email-marketing-tools/	Draft	High
email segmentation	2,100	38	Informational	/blog/email-segmentation-guide/	Not started	Medium
email marketing ROI	800	29	Informational	/blog/email-marketing-roi/	Not started	Medium
welcome email sequence	1,300	22	Informational	/blog/welcome-email-sequence/	Not started	High

Rules

• One primary keyword per page
• 2-5 secondary keywords per page (naturally related)
• If two pages target the same keyword, consolidate or differentiate
• Map keywords to existing pages before creating new ones

Competitor Keyword Analysis

Process

1. Identify 3-5 organic competitors (sites that rank for your target keywords, not just business competitors)
2. Export their top-ranking pages and keywords (using Ahrefs, Semrush, or Sistrix)
3. Find content gaps: keywords competitors rank for that you don't
4. Assess difficulty: can you compete for these terms given your domain strength?
5. Prioritize: high volume + low difficulty + high business value = top priority

What to Look For

• Their pillar pages — What are the broad topics they've invested in?
• Their top traffic pages — What drives the most organic traffic?
• Their weaknesses — Thin content, outdated posts, missing subtopics
• Their link magnets — What content earns them the most backlinks? (Replicate the format)
• Keyword overlap — Where do you already compete? Where are the gaps?

Keyword Research Process (Step by Step)

1. Seed keywords: List 10-20 seed keywords from your product, services, and audience language
2. Expand: Use keyword tools to expand each seed into 50-200 related keywords
3. Classify intent: Tag each keyword with intent (informational, commercial, transactional)
4. Assess difficulty: Filter out keywords above your feasible KD range
5. Estimate value: Which keywords align with business goals? (not all traffic is equal)
6. Cluster: Group keywords into topic clusters
7. Map: Assign each keyword to a page (existing or planned)
8. Prioritize: Score each keyword/page on a 2x2 of difficulty vs. business value
9. Build the calendar: Schedule content creation based on priority
10. Track: Monitor rankings weekly, refresh research quarterly

Quality Gate

• Every target keyword has been classified by search intent
• Keyword difficulty is realistic for the site's current domain strength
• Long-tail opportunities have been identified alongside head terms
• Keywords are organized into topic clusters with clear internal linking plans
• A keyword map exists that assigns one primary keyword per page
• Competitor keyword analysis has been performed to find gaps
• Business value has been considered, not just volume (a 200/month keyword that drives demos > a 10,000/month keyword that drives irrelevant traffic)
• The keyword research is documented and shareable with the team
