What is Organic Traffic Share?
Proportion of traffic from unpaid search.
How to calculate it
Calculate Organic Traffic Share as: Organic sessions / Total sessions × 100. Pull the inputs from your connected data and track the trend over time in your dashboard.
Examples
Example 1
14,000 of 24,000 sessions are organic -> 58%, reducing reliance on paid acquisition.
Example 2
Organic accounts for 16,000 of 28,000 sessions -> 57%. Non-branded organic is growing fastest, showing content and SEO efforts are compounding.
Why it matters
Organic traffic share is the proportion of traffic coming from unpaid search and signals SEO strength and reduced dependence on paid acquisition. A rising share usually means lower blended acquisition costs and more durable, compounding demand. Splitting branded from non-branded organic traffic gives a truer read of SEO progress.
Benchmark context
Higher is generally better for cost efficiency; the right level depends on your channel strategy, but a growing non-branded organic share is a strong sign of SEO health.
Common pitfalls
Ignoring branded vs non-branded split.
