What Google Search Console shows that GA4 doesn't

Google Search Console (GSC) and GA4 are frequently treated as interchangeable, because both are free Google measurement tools. But they measure genuinely different halves of the same journey. Search Console shows what happened before a click, in Google’s search results. GA4 shows what happened after it, on the actual website.

What Search Console (GSC) shows in its data that GA4 structurally cannot

Impressions. How many times a page appeared in Google’s search results, whether or not it was clicked. GA4 has no visibility into this at all — it only knows about a visit once someone actually arrives.

Average position. Where a page tends to rank for a given query. This is entirely a Search Console concept; GA4 does not track ranking position because it is not a search engine measurement, it is a website behaviour measurement.

Click-through rate by query. The percentage of impressions for a specific search term that turned into an actual click. That figure requires knowing both the impression count and the click count for that exact query, which only Search Console has.

Which exact queries bring traffic, at a level of specificity GA4 does not provide. GA4’s Acquisition reports show that a session came from “organic search” via Google, but not the specific words someone typed to find the page — that level of detail is a Search Console-only view.

Indexing and crawl status. Whether a page is actually indexed by Google, and any crawling or indexing errors reported for the site, is a Search Console-specific report with no GA4 equivalent. GA4 only ever sees a visit after a human has clicked through.

Which other sites link in, and which of a site’s own pages link to which. Search Console’s links reporting shows the top external sites linking to the site, and the specific pages they link to. It also has an internal linking report, showing which of the site’s own pages are most linked to from elsewhere on the site. GA4 has no equivalent view of the link structure pointing at or within a site. It is not built to measure links at all, only visitor behaviour once a session has begun.

Whether structured data is implemented correctly. A site may use structured data, also called schema markup, covered in the local-business context on phone calls, maps and the things only a phone can do. Search Console reports specifically on whether that markup is valid and free of errors Google’s own systems can detect. That check has no GA4 equivalent, since GA4 measures behaviour rather than validating markup.

Google Search Console only covers Google Search, not every search engine

It is worth being explicit that Search Console is a Google-specific tool. It reports exclusively on how a site appears in Google’s own search results. It says nothing about a site’s performance in other search engines, which maintain their own separate webmaster tools reporting on their own index. For most Australian small businesses, Google represents the overwhelming majority of organic search traffic. That is why this cluster and this site generally focus on Search Console, rather than covering every search engine’s own equivalent tool. But it is a real, named limitation, not an oversight.

What GA4 (Google Analytics) shows that Search Console cannot

Search Console stops at the click. Everything a visitor does after landing is GA4’s domain: which pages they view next, whether they submit the enquiry form, how long they stay engaged, whether they leave immediately. None of it is something Search Console measures.

Why the clicks and click counts between the two tools do not need to match

Search Console counts a click the moment Google’s own systems record someone clicking a result. GA4 counts a session once a browser has actually loaded the page and executed the tracking code. The gap between those two moments is where several small, expected discrepancies live. A visitor might click but close the tab before the page finishes loading. An ad blocker might block the GA4 tracking script while still allowing the page itself to load. And Google’s own bot-traffic filtering applies differently in each tool. A moderate difference between the two figures is normal and does not mean either tool is broken.

Both tools need their own regular check, reports and reporting, not a one-time setup

Because the two tools answer genuinely different questions, a review process that checks only GA4 and never opens GSC is missing half of what free measurement already provides. A page could be converting every visitor who reaches it, while quietly losing search visibility over time. GA4 alone would never reveal that decline, because it has no way to see impressions or ranking position at all. Building a habit of checking both Search Console and GA4, not just the one that happens to load first, is what actually closes the gap this page describes.

A practical division of labour: metrics SEO teams should track in Search Console and GA4

Question	Tool
Did my page show up for this search term at all?	Search Console
How many people saw it in results but didn’t click?	Search Console (impressions minus clicks)
What specific words did people search to find this page?	Search Console
What did visitors do once they arrived?	GA4
Did the visit lead to an enquiry?	GA4
Is my page actually indexed by Google?	Search Console

Combined reporting: Looker Studio, BigQuery and SEOTesting.com

For reporting beyond either tool’s own interface, Search Console and GA4 data can both be exported into Looker Studio or queried in BigQuery. Third-party tools such as SEOTesting.com layer additional analysis on top of Search Console’s own API. These are useful once the basics above are already being checked manually, not before.

What to do next

If Search Console is not yet linked to the GA4 property, that link — set up once in GA4’s Admin → Product links — is covered as part of setting up GA4: the first week checklist. Confirm Google Tag Manager, or your platform’s native tagging, is firing the GA4 tag correctly. Do this before assuming a data gap is a Search Console problem rather than a tagging one.
