What it is
Competitor Tracking in Google SERP helps you analyze how your website performs relative to other domains in Google search results.
Within Keyword.com, you can:
Compare ranking positions over time
Analyze traffic equity with Share of Voice
Review historical SERP snapshots
Retroactively evaluate competitor movement
This article explains all the ways you can monitor and analyze competitors inside Google SERP Tracking.
Why it matters
SEO is relative.
Ranking #3 may look strong until you discover a competitor owns positions #1 and #2 across your most valuable keywords.
Competitor tracking helps you:
Identify your true search competitors
Monitor market changes
Discover emerging competitors
Measure visibility gains and losses
Prioritize SEO opportunities
Understanding how competitors move is often more valuable than monitoring your own rankings in isolation.
1. Competitor comparison in Historical Charts
Historical Charts allow you to compare your keyword rankings against competitor domains over time.
From the chart view:
Click the Chart icon next to a keyword
Use the competitor dropdown
Select one or more domains to compare
This shows:
Position changes over time
When competitors overtook you
When you gained back rankings
Whether volatility affected multiple domains
For detailed timeline functionality, see: Historical Charts Explained
2. SERP history
SERP History allows you to review the search results collected for a keyword on a specific date.
Each historical snapshot reflects the actual results collected during that update.
The depth available depends on your tracking plan:
The depth shown depends on your tracking model:
Consistent Tracking
SERP History stores the Top 50 results collected during each update.
Enhanced Tracking
SERP History stores the Top 100 results collected during each update.
This allows you to:
See which competitors were ranking on a specific date
Investigate ranking drops
Identify new competitors entering the SERP
Understand how the search landscape changed over time
Because SERP History shows actual collected results, it provides a reliable record of competitor activity and ranking changes.
Note: Accounts still using the legacy Hybrid Tracking model may have historical snapshots collected at different depths.
3. Share of Voice (click equity analysis)
Share of Voice (SoV) measures competitor visibility based on estimated click distribution, not just ranking position.
How it works:
Uses ranking position
Applies estimated CTR models
Multiplies by search volume
Calculates estimated traffic equity
Higher positions + higher search volume = higher Share of Voice.
This gives you:
Top 10 competitor leaderboard
Daily Share of Voice percentage
Visibility change over time

4. Position vs Visibility - what’s the difference?
There are two primary ways to evaluate competitors.
Position-based analysis
Position-based analysis compares ranking positions directly.
Best for:
Keyword-level investigations
Competitor battles
Tracking specific ranking changes
Short-term monitoring
Visibility-based analysis
Visibility-based analysis uses Share of Voice.
Best for:
Market share analysis
Executive reporting
Competitive benchmarking
Long-term trend analysis
Both views provide valuable insight and are most effective when used together.
Investigating competitor gains and losses
When a competitor suddenly gains visibility:
Review Historical Charts
Open SERP History
Compare ranking movements
Look for new URLs entering the SERP
Check whether multiple competitors moved at the same time
This process helps determine whether changes are caused by:
Competitor optimization
New content
Google algorithm updates
SERP-wide volatility
Best practices
Compare competitors when rankings change significantly
Use longer date ranges to identify trends
Review SERP History before reacting to volatilit
Monitor Share of Voice alongside ranking
Focus on visibility, not just positio
Regularly review emerging competitors
