Competitive Share of Voice
Overview
Competitive Share of Voice (SOV) measures your website's visibility in search results compared to competitors for a specific set of keywords. It shows what percentage of potential impressions and clicks your brand captures versus others in your industry or niche.
What is Competitive Share of Voice?
Share of Voice tracks:
- Visibility percentage: Your share of total SERP impressions
- Ranking distribution: How your rankings compare to competitors
- Market presence: Your overall search visibility in your niche
- Competitive position: Where you stand relative to key competitors
Why Share of Voice Matters
Market Position Understanding
- Benchmark performance: Know your competitive standing
- Identify gaps: See where competitors outperform you
- Track market share: Monitor changes in visibility over time
- Set realistic goals: Understand what's achievable
Strategic Planning
- Resource allocation: Focus on winnable battles
- Opportunity identification: Find weak competitor areas
- Threat detection: Spot rising competitors early
- Content strategy: Know which topics to prioritize
Performance Measurement
- Beyond rankings: More holistic than position tracking
- Market context: Your growth relative to market
- Competitive intelligence: Understand competitive dynamics
- Progress tracking: Measure SEO program effectiveness
How Share of Voice is Calculated
Basic Formula
Your SOV = (Your Visibility / Total Visibility) × 100
Visibility Calculation Methods
Method 1: Position-Based Weighting
Each ranking position has a weight based on typical CTR:
Position Weights:
- Position 1: 100 points (30% CTR)
- Position 2: 50 points (15% CTR)
- Position 3: 35 points (10% CTR)
- Position 4-10: Declining points
- Position 11+: Minimal points
Calculation:
- For each keyword, assign points based on your position
- Sum points across all keywords
- Compare to total points possible (all #1 rankings)
Method 2: Traffic Potential
Visibility = Search Volume × Expected CTR for your position
Example:
- Keyword: "keyword research" (10,000 monthly searches)
- Your position: 3 (10% CTR)
- Your visibility: 10,000 × 0.10 = 1,000
Total SOV:
Your SOV = Sum of your visibility / Sum of all visibility × 100
Method 3: SERP Coverage
SOV = (Keywords you rank for / Total keywords in set) × 100
Simpler but less nuanced than weighted methods.

Common Mistakes
Mistake 1: Wrong Competitor Set
Problem: Tracking business competitors, not SERP competitors Solution: Include who actually ranks, not just business rivals
Mistake 2: Keyword Set Too Broad
Problem: Including irrelevant keywords dilutes insights Solution: Focus on business-relevant, monetizable keywords
Mistake 3: Ignoring Volume Weighting
Problem: All keywords weighted equally Solution: Weight by search volume and business value
Mistake 4: Snapshot Mentality
Problem: Looking at single point in time Solution: Track trends, understand trajectory
Mistake 5: No Action Plan
Problem: Tracking SOV but not using insights Solution: Link SOV analysis to content and optimization strategy
Best Practices
Do's
- Track consistently: Same keywords, same frequency
- Weight appropriately: Volume and business value
- Include SERP features: Not just organic positions
- Segment analysis: By category, intent, funnel stage
- Take action: Use insights to drive strategy
Don'ts
- Don't track vanity metrics: Focus on business-relevant keywords
- Don't ignore small competitors: They can steal share quickly
- Don't forget brand terms: Include but segment separately
- Don't set unrealistic goals: Consider competitive landscape
- Don't track in isolation: Combine with other metrics
