What Is Share of Search?
Share of search represents the percentage of branded search queries that include your company name, product name, or service name compared to the total search volume for all competing brands within your industry or category. Unlike traditional SEO metrics that focus on keyword rankings or traffic volumes, share of search directly measures how often consumers actively seek out your brand when expressing purchase intent or information needs in search engines.
When someone searches for your brand name, they have moved beyond casual browsing into active consideration. A page can rank number one for a valuable keyword while your overall brand searches remain flat, indicating that users find your content useful but don't connect it with your brand identity. This disconnect reveals why share of search provides insights that standard SEO dashboards cannot.
How to Calculate Share of Search
The basic share of search calculation is straightforward:
The Formula
Share of Search = (Your Brand Branded Searches ÷ Total Competitive Set Branded Searches) × 100
Practical Example
Consider a software company in the project management space:
- Branded searches for "Asana": 50,000 monthly queries
- Combined branded searches for all competitors (Monday.com, Trello, ClickUp, Basecamp): 200,000
Calculation: (50,000 ÷ 200,000) × 100 = 25%
This means Asana captures one-quarter of all branded search interest in the project management software category. Companies that invest in comprehensive web development and brand-building initiatives often see their share of search grow as consumer awareness increases.
Measures Real Brand Demand
Traditional SEO metrics tell you about traffic and rankings, but share of search reveals whether consumers actively want YOUR brand when making purchase decisions.
Predicts Market Share Changes
Share of search serves as a leading indicator--shifts often precede corresponding market share changes by several months.
Validates Marketing Investments
Track share of search before and after campaigns to see if brand-building efforts translate into genuine consumer consideration.
Provides Crisis Early Warning
Sudden share declines often precede other negative indicators, enabling rapid response before brand damage compounds.
Share of Search vs. Share of Voice: Understanding the Difference
These related metrics serve different purposes:
Share of Voice (SOV) in SEO
Measures your brand's visibility across SERPs for target keywords--including organic listings, featured snippets, knowledge panels, and other SERP features. It reflects how much of the available search real estate your brand occupies.
Share of Search
Specifically measures branded search queries--how often consumers actively search for your brand compared to competitors. It captures demand from consumers who have already developed brand awareness.
When to Use Each
| Use Share of Search When... | Use Share of Voice When... |
|---|---|
| Understanding brand awareness trends | Measuring content visibility |
| Analyzing competitive brand demand | Evaluating technical SEO |
| Validating marketing campaigns | Tracking SERP feature dominance |
| Predicting market share changes | Optimizing for target keywords |
Best Practice: Track both metrics together for a complete picture of brand performance.
Determine which brands constitute your competitive set. This should include brands that consumers actually consider alongside yours--not every company in your industry. Reflect consumer consideration sets rather than industry classifications.

Strategic Applications of Share of Search
Competitive Benchmarking

Campaign Performance Measurement
Establish baselines before campaigns, then track share changes. Significant increases indicate successful brand-building; flat or declining share may signal messaging problems.
Crisis Monitoring and Recovery
During brand crises, share of search provides early warning. Rising share during recovery validates reputation management success.
Market Entry Strategy
For new markets or products, baseline share of search reveals whether consumers associate your brand with the new category. Low baseline indicates need for awareness investment.
