Analytics
GA4 for SEO: reports, metrics and practical use
Google Analytics 4 differs fundamentally from Universal Analytics. New data model, events instead of sessions, no traditional bounce rate. We cover which GA4 reports are genuinely useful for SEO and how to read them.
Since July 2023, Universal Analytics has stopped processing new data. GA4 is the only version of Google Analytics still operational. For SEO practitioners this means mastering a new interface, new terminology, and a new way of thinking about analytics.
GA4 has a steeper learning curve but is more powerful: cross-platform tracking, predictive metrics, and more flexible segmentation. For SEO tasks you need to know 5–7 key reports — the rest can be learned gradually.
GA4 vs Universal Analytics
| Universal Analytics (UA) | Google Analytics 4 (GA4) |
|---|---|
| Session-based | Event-based |
| Bounce Rate | Engagement Rate |
| Pageviews as primary hit | All actions are events of the same type |
| Goals | Conversions based on events |
| 26+ months data retention | Up to 14 months (default 2 months) |
| Standard reports cover most tasks | Custom reports and Explorations needed |
GA4 data model
In GA4, everything is an event. A page view is page_view, a click is click, a scroll is scroll, a form submission is form_submit. This makes the data model universal for both web and mobile applications.
Engaged session
A session is considered engaged if it lasts 10+ seconds or includes 2+ page views
Data retention
Maximum retention period for user data in GA4
Events per session
Maximum number of unique events in one GA4 property
UA historical data
GA4 does not import Universal Analytics data — it starts from scratch
Organic traffic in GA4
In GA4, organic traffic from Google is found under Reports → Acquisition → Traffic acquisition. The channel is called Organic Search. Ensure that the attribution model is set to 'Data-driven' or 'Last click' in property settings.
Path: Reports → Life cycle → Acquisition → Traffic acquisition → filter by channel 'Organic Search'. Here you see sessions, active users, engagement, and conversions from organic search.

Landing Pages is one of the most important reports for SEO. It shows which pages users land on from organic search and how they behave once there.
Path: Reports → Engagement → Landing page. Add a secondary dimension 'Session channel' and filter by Organic Search. You get a list of pages with metrics: sessions, engaged sessions, average duration, conversions.
| Metric pattern | What it signals | Action |
|---|---|---|
| High traffic + low conversions | Page attracts but doesn't convert | Improve CTAs and content relevance |
| Low traffic + high conversions | Converts well but has low visibility | Strengthen SEO optimisation and links |
| High bounce rate | Content doesn't match user intent | Rework content to match the query |
| Traffic drop over period | Lost positions or demand shift | Check positions in GSC |
Engagement instead of bounce rate
GA4 has no traditional bounce rate. Instead it has Engagement Rate: the share of sessions where the user spent 10+ seconds, completed a conversion, or viewed 2+ pages.
Bounce Rate in GA4 is the inverse of Engagement Rate: the share of sessions WITHOUT engagement. Formula: Bounce Rate = 1 - Engagement Rate. A high Bounce Rate in GA4 (40%+) means users leave quickly — the page likely doesn't match the query.
Organic conversions
Setting up conversions in GA4: Admin → Conversions → New conversion event. Mark an event as a conversion (e.g. form_submit, purchase, generate_lead). It will then appear in reports.
For SEO reporting, segment conversions by Organic Search channel in the Acquisition reports or in Explorations. This lets you see the ROI of the organic channel separately from paid.
GSC integration
GA4 and GSC can be linked: Admin → Product links → Search Console links. After linking, a dedicated 'Search Console' section appears in GA4 with GSC data directly inside Analytics.
| GSC report in GA4 | What it shows |
|---|---|
| Google organic search queries | Queries + clicks + CTR + position from GSC |
| Google organic search pages | Pages with organic traffic from GSC data |
| Google organic search countries | Geography of organic traffic |
| Google organic search devices | Desktop/Mobile/Tablet breakdown of organic traffic |

FAQ
page_view event for 404 pages. To isolate them in reports, add a custom dimension or set up a page_not_found event via GTM: trigger on a URL containing /404 or a page title matching 'Page not found'.
