In plain English
Share of voice is a way of asking: out of all the possible attention available for a group of keywords, how much of it are we getting? If you rank in the top three for half the keywords in your market, your share of voice is much higher than if you are buried on page two.
Technical definition
Share of voice is a competitive metric that expresses the percentage of total organic impressions, clicks, or rankings your site captures for a defined keyword universe, relative to the total available or relative to the combined share of all competitors.
Quick example
For 100 keywords, your site earns an estimated 5,000 clicks a month and all competitors combined earn 20,000. Your organic share of voice is 25%.

Why Share of Voice matters
Rankings and traffic are useful, but share of voice shows how you compare to everyone else in your market.
It measures market position
A traffic increase looks good, but if competitors grew faster, you are still losing ground. Share of voice makes that clear.
It surfaces cannibalisation and gaps
A falling share of voice highlights where competitors are outranking you and where you have coverage holes.
It is a board-level metric
Stakeholders understand market share. Share of voice translates SEO into language that fits wider business reporting.
It tracks the impact of SERP features
Even if rankings are flat, a competitor gaining featured snippets or video carousels can steal share without outranking you.
How it works
Share of voice can be calculated in several ways, but the principle is the same.
- 1
Define the keyword universe
Pick the set of keywords that represent your market or product category.
- 2
Collect ranking or click data
Use a rank tracker, Search Console, or third-party tool to estimate clicks for each keyword.
- 3
Estimate traffic per site
For each keyword, estimate the clicks each competitor earns based on ranking position and search volume.
- 4
Calculate the percentage
Divide your total estimated clicks by the total estimated clicks for the whole set.
Types and variations
Share of voice can be measured for different channels and intents.
Organic share of voice
The share of estimated organic clicks your site captures for a keyword set.
Paid share of voice
The share of paid impressions or clicks for a keyword set.
Social share of voice
The share of brand mentions, hashtags, or engagement in a market.
SERP feature share
The share of featured snippets, videos, images, or other rich results for a keyword set.
Branded vs non-branded share
Separating brand-name searches from generic market searches for a clearer picture.
Real examples
How share of voice changes strategy and reporting.
A site that doubles its organic SOV after a refresh
A client updates and consolidates its content hub. Organic share of voice rises from 8% to 19% for its core keyword set over 12 months.
A brand with strong SOV but low conversion
The brand has high visibility but the traffic is not converting. The insight leads to a landing page overhaul that improves both rankings and conversion.
A vanity keyword with 100% SOV
The company brags about dominating a branded term with no search volume. The metric looks impressive but drives no business value.
A competitor ignored because rankings look okay
Rankings for tracked keywords are stable, but SOV shows a competitor is winning featured snippets and images. Traffic drops while rankings stay flat.
Best practices
A good share of voice calculation is accurate, stable, and actionable.
What to do
- Use a consistent keyword set that reflects your real market
- Include branded and non-branded keywords separately
- Track by category or product line, not only sitewide
- Compare against a fixed set of competitors, not the whole web
- Re-baseline quarterly as the market and keyword set evolves
- Combine share of voice with conversion data to show business impact
What to avoid
- Calculating share on a tiny or irrelevant keyword set
- Changing the keyword set too often and losing trend data
- Using only position data when click data is available
- Comparing branded share to non-branded share in one number
- Ignoring zero-click SERPs where share is harder to measure
Common mistakes
Treating position one as the only thing that matters
A page one ranking outside the top three gets far fewer clicks. Share of voice weights visibility more accurately.
Using ranking alone
Rankings do not account for SERP features or search intent. Click-based share of voice is usually more meaningful.
Forgetting about brand vs non-brand
Branded searches inflate your share. Separate the two to see real market performance.
Share of voice is the board-level SEO metric
Rankings and traffic are tactical. Share of voice is strategic. It tells you whether your brand owns the conversation or is just participating. A falling share of voice is often the first warning that a competitor is gaining ground, even before traffic drops. It is the metric that translates SEO into market position.
- SOV connects SEO to business outcomes more clearly than rankings alone
- It reveals the full competitive landscape, not just your own numbers
- SERP feature share can explain traffic changes that rankings cannot
- SOV is best tracked by category and product line
- A small SOV improvement in a large market is worth more than a large share of a tiny one

Frequently asked questions
How is SEO share of voice calculated?
The most common method is to estimate clicks your site earns for a keyword set, then divide that by the total estimated clicks for the same set across all tracked competitors.
Is share of voice the same as market share?
Not exactly. Market share is based on revenue or customers. Share of voice is based on visibility or mentions. The two often correlate but are not the same.
What tools measure share of voice?
Semrush, Ahrefs, and custom rank tracking dashboards are the most common tools. Google Search Console can also be used for your own data.
