SEO Keyword Strategist
Overview
Keywords are entity pointers, not density targets. Google's Knowledge Graph holds 54+ billion entities and 1.6+ trillion facts. Modern keyword strategy is about mapping content to entities and intent, not counting keyword occurrences.
Dead Metrics — Stop Using These
| Myth |
Reality |
| Keyword density 0.5-1.5% |
No correlation with rankings (2026 study, 1,536 results). Google uses NLP, not word counting |
| LSI keywords |
Confirmed myth. John Mueller: "There's no such thing as LSI keywords." Use "semantically related terms" instead |
| Content scoring tools predict rankings |
Correlation 0.17-0.30 (weak). Use for gap finding, not score chasing |
| Search volume is accurate |
Google Keyword Planner overestimates 54% of the time. Use volumes as directional only |
Intent Classification
| Intent |
% of Searches |
Content Type |
AI Overview Risk |
| Informational |
52.65% |
Guides, how-tos, explainers |
HIGH — AI answers directly |
| Navigational |
32.15% |
Brand/product pages |
LOW — users want specific site |
| Commercial |
14.51% |
Comparisons, reviews, "best X" |
MEDIUM — sweet spot for clicks |
| Transactional |
0.69% |
Product/checkout pages |
LOW — users want to buy |
Priority: Target commercial intent keywords — high conversion potential, not fully absorbed by AI Overviews. Informational head terms are increasingly zero-click (58.5% US, 83% when AI Overviews appear).
Entity-First Keyword Strategy
Google shifted from "strings" to "things." Optimize for entities, not keyword strings.
Three pillars:
- Precision — Each page = one canonical entity. Align title, H1, and schema
mainEntityOfPage
- Coverage — Site collectively covers all subtopics that define your niche (topical authority)
- Connectivity — Internal links mirror Knowledge Graph entity relationships
Practical steps:
- Place primary keyword in title, H1, first paragraph, and 1-2 subheadings naturally
- Cover expected subtopics comprehensively (check People Also Ask for gaps)
- Use schema markup to explicitly declare entities (Product, Organization, etc.)
- Write for meaning, not matching — Google's NLP (BERT, MUM, Gemini) understands synonyms and context
Keyword Clustering
SERP-based clustering is the gold standard. If 3+ of the same URLs appear in top 10 for two keywords, they belong in one cluster.
Rule: One search intent = one keyword cluster = one page.
Method:
- Collect target keywords
- Check SERP overlap (same pages ranking = same cluster)
- Verify intent alignment (informational vs commercial)
- Assign one cluster per page — never create separate pages for keywords in the same cluster
Cannibalization Detection
Not every instance of multiple pages ranking for the same keyword is a problem. Ahrefs reports 9,700 cases on their own site — almost none need fixing.
It's a problem when:
- Pages swap positions 3+ times in 7 days (red flag)
- Rankings drop 5-15 positions when "wrong" page is selected
- CTR is split between pages serving identical intent
It's NOT a problem when:
- Both pages rank stably in top positions
- Pages serve different intents (blog post = informational, product page = transactional)
- Total traffic from both exceeds what one page would get
Detection via GSC API:
Query dimensions: ["query", "page"]
Group by query → count distinct pages
Flag: queries where count(page) > 1 AND positions swap frequently
Resolution decision:
| Signal |
Action |
| Position swapping, same intent |
Consolidate — merge weaker into stronger, 301 redirect. Case studies show +200-466% traffic |
| Different intents, both stable |
Leave it — keyword diversification is beneficial |
| Same intent, one clearly dominant |
Re-optimize — change weaker page to target different cluster |
Zero-Click Strategy
58.5% of US searches result in zero clicks. When AI Overviews appear, 83% zero-click.
- For informational keywords: optimize for AI Overview citation as brand visibility (even without clicks)
- For commercial keywords: these retain higher CTR — prioritize them
- Track CTR alongside rankings — #1 with 0.6% CTR on an AIO query may be less valuable than #5 without AIO
Anti-Patterns
| Don't |
Why |
| Target keyword density percentages |
Dead metric — no ranking correlation |
| Use "LSI keyword" tools |
LSI is a myth; use topical gap analysis instead |
| Chase content scoring tool numbers |
0.17-0.30 correlation; score ≠ ranking |
| Trust search volume precision |
54% overestimated; use as directional only |
| Create separate pages for same-cluster keywords |
Causes cannibalization; one cluster = one page |
| Treat all multi-page rankings as cannibalization |
Often beneficial; check for actual harm first |
| Ignore zero-click data |
58.5% of searches get no clicks; factor into strategy |
