Content Variation Engine: Multi-Location Uniqueness via Jaccard Scoring

runnable

System for generating unique content variations across multiple locations or verticals without duplicate content penalties. Uses Jaccard similarity scoring (target 0.75-0.85) to measure uniqueness. Covers the 7 variation axes and rewrite protocol.

Content Variation Engine: Multi-Location Uniqueness via Jaccard Scoring

Multi-location businesses need unique content per location — not the same page with "[CITY]" swapped out. Jaccard scoring measures actual phrase-level uniqueness. This system targets 0.75-0.85 similarity (on-topic but not duplicate).

Why Jaccard Scoring

Jaccard similarity measures shared phrases between two documents:

Jaccard(A, B) = |A ∩ B| / |A ∪ B|
  • Score of 1.0 = identical documents
  • Score of 0.0 = no shared phrases
  • Target: 0.75-0.85 — similar enough to be on-topic, unique enough to avoid duplicate content penalties

Scores above 0.90 = near-duplicate = Google may deindex or suppress the variant page. Scores below 0.70 = so different they may not rank for the same keyword family.

The 7 Variation Axes

Each location page variation draws uniqueness from these seven sources:

Axis 1: Geographic References

  • City name, county, neighborhood names
  • Local landmarks, districts, zip codes
  • Regional terminology (Chicagoland vs greater Chicago area)
  • Distance references ("serving [City] and surrounding [radius] mile area")

Axis 2: Local Social Proof

  • Customer testimonials from that specific city
  • Named projects in that area
  • Local contractor/partner mentions

Axis 3: Local Context

  • City-specific regulations or codes (if applicable)
  • Local weather patterns affecting the service
  • Area-specific pricing considerations

Axis 4: Different Examples

  • Same service explained with different examples per location
  • Different case study or before/after for each city

Axis 5: Different Stats

  • Local stat sourced from city/county data
  • Area-specific market condition
  • Neighborhood-level data if available

Axis 6: Opening and Closing Paragraphs

  • Intro and CTA rewritten entirely — never shared across variants
  • Different opening hook angle per location

Axis 7: FAQ Variation

  • 2-3 FAQ questions that are city-specific
  • Local permit, code, or process questions
  • City-named queries ("What do roofing companies in Denver charge?")

Rewrite Protocol

Step 1: Write the master page (anchor location — typically headquarters or primary market)

Step 2: For each variant location, apply variation to these sections in order:

| Section | Change Required | Notes | |---------|----------------|-------| | Title tag + H1 | Always | City name mandatory | | Intro paragraph | Full rewrite | New opening hook | | Social proof section | New testimonials | Location-specific | | Process/differentiator section | Light edit | Same structure, new examples | | Local context section | New content | City-specific info | | FAQ section | 2-3 unique Qs added | Keep 3-4 from master | | CTA section | Light edit | Same CTA, city name | | Meta description | Full rewrite | City + unique value prop |

Step 3: Run Jaccard check before publishing.

Jaccard Measurement (Manual Method)

For teams without automated tools:

  1. Extract all unique 3-word phrases from master page
  2. Extract all unique 3-word phrases from variant page
  3. Count phrases in both (intersection)
  4. Count total unique phrases (union)
  5. Divide intersection by union

If score exceeds 0.85: identify the repeated phrase blocks and rewrite those sections specifically.

Quick proxy test: If 3 consecutive sentences in the variant are word-for-word identical to the master, the section needs a rewrite.

Minimum Uniqueness by Page Section

| Section | Minimum Unique Content | |---------|----------------------| | H1 + Title | 100% (city-modified) | | Intro paragraph | 100% (full rewrite) | | Social proof | 100% (new testimonials) | | Body sections | 40-60% unique per section | | FAQ | 30%+ unique questions | | CTA | 20%+ unique (city name minimum) |

Overall page: Target 35-40% unique content at minimum. 50%+ is the safe zone.

Scale Note

At 20+ location pages, manual variation becomes unsustainable. At that scale:

  • Templatize the stable sections (process, credentials, guarantees)
  • Build a local data insert layer (city name, local stat, testimonial)
  • Write new intro paragraphs (the highest-weight uniqueness section) for every page
  • Automated Jaccard checks before publish
