Landing Page Performance vs Bounce, PostHog

Landing Page Performance vs Bounce for PostHog stores. Tracked live in Vortex IQ Nerve Centre. How to read it, why it matters, and how to act on it.

Metrics type: Key Metrics • Category: Analytics

At a glance

Landing Page Performance vs Bounce is a cross-platform table that sets each landing page’s performance against its bounce rate. It is built to catch a costly co-occurrence: a slow or poorly performing landing page that also bleeds visitors before they engage. When sluggish load and high bounce show up on the same page, you have found a leak you are paying to fill with traffic, and this table ranks those pages so you fix the worst first.

What it counts	Each landing page with its performance signal alongside its bounce rate, ranked to surface the worst combinations.
Sample type	Backend API data from PostHog page and session data, aligned with performance signals on the standard data refresh.
Why it matters	A slow landing page that also bounces visitors wastes acquisition spend twice. Pairing the two metrics turns a vague “the page is bad” into a ranked fix list.
Reading the value	Read each row as a page. The pages where weak performance and high bounce co-occur are the priority fixes.
Currency	count
Time window	30D
Alert trigger	slow landing page + high bounce co-occur
Sentiment key	ph_xc_landing_page_perf_vs_bounce

Calculation

Calculated automatically from your PostHog data alongside your connected performance signals. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.

Worked example

A representative reading of Landing Page Performance vs Bounce for a typical merchant on PostHog. Suppose a paid-traffic landing page loads slowly and bounces 71% of visitors, while your homepage loads fast and bounces 38%. The table ranks the slow, high-bounce page at the top because that is where money leaks: you pay for the click, the page is slow, the visitor leaves. After an image-optimisation fix on 02 Jun 26, the page’s bounce falls to 49% and it drops down the ranking. Cross-reference Bounce Rate and Top Pages for the per-page detail.

Reconciling against the vendor’s own dashboard

Where to look in PostHog’s own dashboard:

In PostHog, a trend or table insight on entry pages with a bounce filter gives the bounce side per landing page. The performance side comes from your connected performance signals. Line the two up per page to reproduce this table. Bounce definitions, single-event versus single-pageview sessions, are the main source of difference.

Why the Vortex IQ value may legitimately differ:

Reason	Direction	What to do
Bounce definition. A bounce as a single pageview versus a single event gives different rates.	Variable	Match the bounce definition.
Landing-page grouping. Query strings can split one landing page into several rows.	Variable	Apply URL cleaning.
Performance source. The performance signal may come from a separate connector with its own sampling.	Variable	Confirm the performance source.

Cross-connector reconciliation: this card already joins PostHog with performance data. For persistent oddities, use Vortex Mind to trace the source.

Known limitations / merchant FAQs

Q: How often does Landing Page Performance vs Bounce update? The card refreshes on the standard data refresh (typically every 30-60 minutes for live integrations). For real-time signals, force a manual refresh from the dashboard.

Q: Why focus on pages where both signals are bad? A page can be slow but still convert, or fast but naturally high-bounce. The expensive case is when slow load and high bounce co-occur on a page you are paying to send traffic to. That combination is the highest-leverage fix.

Q: A page has high bounce but it is informational. Is that a problem? Not always. A blog or support page that answers a question in one visit will bounce by design. Judge bounce against the page’s purpose, which is why this card pairs it with performance and ranking.

Q: Can I customise the alert threshold? Yes, alert thresholds are configurable per profile in the Alert Rules tab. Adjust to match your business baseline rather than relying on the generic default.
