Share of Search: Your Slice of the Search Market
Share of search is the share of brand-related queries that involve your brand, and it often predicts market share before sales data does.
Share of Search is the percentage of brand-related searches your brand captures.
What It Is
Share of search measures how much of the brand-related search volume goes to your brand compared with competitors.
It is calculated from searches that include brand names or clear brand-intent terms across a category.
Marketing teams track it because it often predicts market share before sales data confirms the shift.
Why It Matters
- Share of search is a leading indicator of market share.
- It responds quickly to campaigns and news.
- It reveals awareness shifts before revenue data confirms them.
- It is comparable across competitors that track the same set.
- It connects search marketing directly to business goals.
How to Measure It
- Define the set of brand-related searches for your category.
- Track branded search volume for you and each competitor.
- Divide your brand volume by the total category volume.
- Watch the trend over months, not days.
- Segment by market or product line when it helps.
- Refresh the search set as the category evolves.
How to Improve It
- Run brand awareness campaigns.
- Earn press, links, and unlinked mentions.
- Make sure your brand appears where your audience searches.
- Win brand-related features like knowledge panels.
- Respond quickly when competitors gain share.
- Connect brand searches to brand experience so demand converts.
Common Mistakes
- Measuring share only during campaign periods.
- Including unrelated searches that inflate your share.
- Comparing share across different search sets.
- Ignoring the campaigns driving competitor gains.
- Treating search share as a vanity metric with no action behind it.
Before: a brand sees sales dip but cannot explain why.
After: share of search data shows competitor awareness rising.
The result: the team responds with a brand campaign early.
The lesson: search share moves before market share does.
Quick Tip
