| 1 | # Keyword Cannibalization Detection |
| 2 | |
| 3 | > Find pages competing for the same keyword |
| 4 | |
| 5 | ## What is Keyword Cannibalization |
| 6 | |
| 7 | **Problem**: Multiple pages on your site targeting the same keyword. |
| 8 | |
| 9 | ``` |
| 10 | /blog/best-crm-software → Target: "best crm" |
| 11 | /guide/crm-comparison → Target: "best crm" |
| 12 | /products/crm → Target: "best crm" |
| 13 | ``` |
| 14 | |
| 15 | **Consequences**: |
| 16 | - Google doesn't know which to rank → none rank well |
| 17 | - Internal link equity is diluted |
| 18 | - Confusing user experience |
| 19 | - Wasted crawl budget |
| 20 | |

| 22 | |
| 23 | ## Detection Methods |
| 24 | |
| 25 | ### Method A: With GSC Data (Recommended) |
| 26 | |
| 27 | ``` |
| 28 | Import GSC "Queries" report |
| 29 | ↓ |
| 30 | Group by keyword |
| 31 | ↓ |
| 32 | Find keywords with multiple URLs |
| 33 | ↓ |
| 34 | Analyze each URL's: |
| 35 | - Impressions |
| 36 | - Clicks |
| 37 | - Average position |
| 38 | - Position fluctuation |
| 39 | ↓ |
| 40 | Identify cannibalization |
| 41 | ``` |
| 42 | |
| 43 | **Cannibalization Signals**: |
| 44 | - Same keyword has 2+ URLs with impressions |
| 45 | - Ranking fluctuates frequently (Google is indecisive) |
| 46 | - Both pages stuck at positions 5-15 |
| 47 | |
| 48 | ### Method B: Without GSC Data |
| 49 | |
| 50 | ``` |
| 51 | Input target keyword list |
| 52 | ↓ |
| 53 | For each keyword: |
| 54 | - site:domain.com "keyword" search |
| 55 | - Analyze multiple results returned |
| 56 | ↓ |
| 57 | Check content overlap between pages |
| 58 | ↓ |
| 59 | Identify potential cannibalization |
| 60 | ``` |

| 64 | ## Output Format |
| 65 | |
| 66 | ```markdown |
| 67 | # Keyword Cannibalization Report |
| 68 | |
| 69 | ## Found X Cannibalization Groups |
| 70 | |
| 71 | ### Group #1: "best crm software" |
| 72 | |
| 73 | | URL | Position | Impressions | Clicks | Content Angle | |
| 74 | |-----|----------|-------------|--------|---------------| |
| 75 | | /blog/best-crm-2024 | #8 | 5,000 | 120 | Review article | |
| 76 | | /guide/crm-comparison | #12 | 3,200 | 45 | Comparison guide | |
| 77 | | /products/crm | #15 | 1,800 | 30 | Product page | |
| 78 | |
| 79 | **Diagnosis**: Three pages have different angles but titles/H1s all target "best crm" |
| 80 | |
| 81 | **Recommendation**: Differentiation strategy |
| 82 | - /blog/best-crm-2024 → Keep, primary target for "best crm software" |
| 83 | - /guide/crm-comparison → Retarget to "crm comparison guide" |
| 84 | - /products/crm → Retarget to brand term "YourBrand CRM features" |
| 85 | |

| 88 | ### Group #2: "how to use crm" |
| 89 | |
| 90 | | URL | Position | Content Overlap | |
| 91 | |-----|----------|-----------------| |
| 92 | | /blog/crm-tutorial | #11 | 80% | |
| 93 | | /help/getting-started | #14 | 75% | |
| 94 | |
| 95 | **Diagnosis**: Two pages with highly overlapping content |
| 96 | |
| 97 | **Recommendation**: Merge strategy |
| 98 | - Merge into /blog/crm-tutorial (higher traffic) |
| 99 | - 301 redirect /help/getting-started to merged page |
| 100 | - Or: Rewrite /help/getting-started as product-specific tutorial |

| 106 | | Keyword | Strategy | Keep URL | Action for Others | |
| 107 | |---------|----------|----------|-------------------| |
| 108 | | best crm software | Differentiate | /blog/best-crm-2024 | Update titles | |

| 110 | | ... | ... | ... | ... | |
| 111 | ``` |
| 112 | |
| 113 | --- |
| 114 | |
| 115 | ## Four Resolution Strategies |
| 116 | |
| 117 | ### 1. Merge |
| 118 | |
| 119 | **When**: Content overlap >70% |
| 120 | |
| 121 | ``` |
| 122 | A + B → A (the better one) |
| 123 | B → 301 to A |
| 124 | ``` |
| 125 | |
| 126 | **Steps**: |
| 127 | - Pick the page with better traffic/ranking |
| 128 | - Merge unique content from the other page |
| 129 | - Set up 301 redirect |
| 130 | - Update internal links |
| 131 | |
| 132 | ### 2. Redirect |
| 133 | |
| 134 | **When**: One page is clearly weaker |
| 135 | |
| 136 | ``` |
| 137 | Weak page → 301 to strong page |
| 138 | ``` |
| 139 | |
| 140 | **Steps**: |
| 141 | - 301 redirect directly, no content merge |
| 142 | - Ensure strong page covers weak page's intent |
| 143 | |
| 144 | ### 3. Differentiate |
| 145 | |
| 146 | **When**: Two pages serve different intents |
| 147 | |
| 148 | ``` |
| 149 | A → Keyword X |
| 150 | B → Keyword Y (related but different) |
| 151 | ``` |
| 152 | |
| 153 | **Steps**: |
| 154 | - Modify title, H1, meta description |
| 155 | - Adjust content angle |
| 156 | - Update internal link anchor text |
| 157 | |
| 158 | ### 4. Delete |
| 159 | |
| 160 | **When**: Page has no value |
| 161 | |
| 162 | ``` |
| 163 | Low-quality page → Delete or noindex |
| 164 | ``` |
| 165 | |
| 166 | **Steps**: |
| 167 | - 410 delete (explicitly tell Google) |
| 168 | - Or noindex (keep but don't rank) |
| 169 | |
| 170 | --- |
| 171 | |
| 172 | ## Usage |
| 173 | |
| 174 | ```bash |
| 175 | # With GSC data |
| 176 | /seo cannibalization --gsc [csv-file] |
| 177 | |
| 178 | # With keyword list |
| 179 | /seo cannibalization --keywords "keyword1, keyword2, ..." |
| 180 | |
| 181 | # Analyze entire site |
| 182 | /seo cannibalization https://example.com |
| 183 | ``` |
| 184 | |

| 186 | |
| 187 | ## Prevention |
| 188 | |
| 189 | ### Keyword Mapping |
| 190 | |
| 191 | Before writing new content, check if existing pages cover that keyword: |
| 192 | |
| 193 | ```markdown |
| 194 | | Target Keyword | Existing Page | Status | |
| 195 | |----------------|---------------|--------| |
| 196 | | best crm | /blog/best-crm-2024 | Covered | |
| 197 | | crm pricing | — | Available | |
| 198 | | crm vs erp | /blog/crm-erp-difference | Covered | |
| 199 | ``` |
| 200 | |
| 201 | ### Content Planning Principles |
| 202 | |
| 203 | 1. **One keyword = One page** |
| 204 | 2. Check keyword mapping before new content |
| 205 | 3. Run cannibalization detection regularly |
| 206 | 4. Keep internal link anchors consistent with target keywords |
