What is Organic Traffic Growth?

A period-over-period SEO KPI. Negative growth means traffic fell versus the baseline.

  • Same metric (sessions, users, or GSC clicks)
  • Align seasonality (YoY often clearer than MoM)
  • Annotate algorithm updates

The Formula

Organic Traffic Growth
Growth % = ((New traffic − Old traffic) ÷ Old traffic) × 100

Worked Example

Scenario: Organic sessions rose from 8,000 to 10,400.
Step 1: Delta = 10400 − 8000 = 2400
Step 2: (2400 ÷ 8000) × 100 = 30%
Answer: Organic traffic grew 30%.

Common Use Cases

  • Monthly reporting: MoM/YoY growth
  • Post-launch reviews: content impact
  • Incident analysis: quantify drops

Pro Tips

  • Segment brand vs non-brand
  • Watch index coverage when traffic falls
  • Use comparable date ranges

Limitations: Organic Traffic Growth results are educational SEO planning aids—not guarantees of rankings or traffic. Search algorithms and attribution models vary.
