Also known as: Single-page Session Rate
Bounce rate is the percentage of visitors who arrive on a page and leave without any further interaction — no second page, no link click, no form submission. It measures how many sessions are single-page 'bounces' out of all sessions that started on that page.
It is a fast proxy for message-match and page quality. A high bounce rate usually signals that the page did not deliver what the visitor expected: wrong message for the traffic source, slow load, confusing layout, or a missing next step. Note that Universal Analytics defined a bounce as a single-page session with no interaction, while Google Analytics 4 replaced it with 'engagement rate' — bounce rate in GA4 is simply the inverse of engaged sessions.
Worked example: an affiliate's paid campaign sends 5,000 visitors to a landing page. If 4,250 leave without any interaction, the bounce rate is 4,250 / 5,000 = 85%. That means only 750 visitors even begin the funnel — and if the page were fixed to bounce at 55%, that same spend would feed 2,250 engaged visitors, tripling the top of the funnel.
Context matters when reading the number. A well-targeted, single-purpose landing page with a form can bounce high yet convert well if the visitor completes the goal on that same page; conversely a blog post with an 80% bounce may be fine. Always read bounce rate alongside conversions, not on its own.
Analytics fires a tag when a visitor lands on a page. If the session ends with no qualifying second interaction — no additional pageview, event, or engagement signal — it is counted as a bounce. Bounce rate is bounces divided by total entrances on that page, expressed as a percentage.
Because the metric is source-sensitive, you segment it: paid search, organic, social, and email traffic each bounce differently. A spike in one channel points to a mismatch between the ad's promise and the page's content. GA4's engagement-based model counts a session as engaged if it lasts over 10 seconds, has a conversion, or has two or more pageviews, so 'bounce' there is anything failing all three.
Why it matters for partnership: Every bounced visitor is traffic you paid for that never entered the broker's funnel, so cutting bounce rate directly recovers lost commissions. For IBs and affiliates, tightening message-match and load speed on landing pages is one of the cheapest ways to lift funded accounts.
An affiliate ran Google Ads for 'zero commission stock trading' pointing to an eToro homepage rather than a dedicated page. Bounce rate hit 85% and cost-per-registration was punishing. After building a message-matched landing page that opened with the exact ad promise and a load time under 2 seconds, bounce fell to 52% and registrations per 1,000 clicks roughly doubled on the same budget.
Match the landing page's headline word-for-word to the ad or link that sent the visitor, and keep load time under 3 seconds — mismatched message and slow pages are the two biggest bounce drivers.
Sending targeted keyword traffic to a generic homepage instead of a specific, message-matched landing page, which inflates bounce rate and wastes ad spend.
It depends on page type and traffic source. Landing pages often sit at 60-90%, content pages 40-60%. Compare against your own baseline and channel, not a single universal target.
GA4 shifted to engagement rate as the primary metric. Bounce rate still exists but is now defined as the inverse of engagement rate rather than the old single-page definition.
Google has stated it does not use analytics bounce rate directly as a ranking signal, but the poor experience that causes bounces can indirectly affect rankings.
Improve message-match with the ad, speed up load time, put a clear CTA above the fold, and remove distractions that pull attention from the single goal.
No. A single-page landing page where visitors complete the goal (like a form) can bounce high yet convert well. Always read bounce alongside conversions.
Divide the number of single-page sessions (no further interaction) by total entrances on the page, then multiply by 100.
