What is Bounce Rate?

Bounce Rate is the percentage of website sessions where the visitor viewed a single page without engagement. In GA4 the definition shifted: a session under 10 seconds with no conversion and no second pageview is "bounced." High bounce isn't always bad — depends on page type and user intent.

// formula (GA4)

GA4's "engaged session" = 10+ seconds long OR ≥1 conversion OR ≥2 pageviews. Sessions failing all three are bounces. Looser than Universal Analytics' single-page-view definition.

// industry averages

• Content site / blog — 65-85% (high is normal; users read and leave).
• E-commerce category page — 40-55%.
• E-commerce product page — 50-70%.
• SaaS landing page — 40-60%.
• Corporate homepage — 30-50%.
• Lead capture / one-pager — 70-90% (single-purpose).

// causes of high bounce

1. Page speed — pages over 3s see bounce up 32%.
2. Mobile-unfit design — desktop layout forced onto mobile.
3. Ad-page mismatch — "discounted running shoes" ad pointing to generic homepage.
4. Bad traffic — irrelevant keywords; search waste.
5. Pop-up overload — cookie + newsletter + WhatsApp on first paint.

// metrics to read alongside bounce

• Average engagement time — if bouncing users still spent 30s, content was fine; intent was just one-page.
• Scroll depth — 70%+ scroll counts as engagement even if technically bounced.
• Conversion rate — bouncing traffic that converts is fine; don't panic.

// fixing bounce

• Speed — Core Web Vitals compliance.
• Intent match — ad → relevant landing page.
• Content structure — answer the user's question above the fold.
• Internal linking — related-content blocks, "see also" recommendations.
• CTA clarity — user must know the next step.
