Google Analytics 4 measures what visitors do after they reach your site: sessions, engagement, events and conversions. Google Search Console shows what happens before the click: which queries your site appears for in Google Search, how many clicks it gets, its average position, and whether your pages are indexed. One covers on-site behaviour, the other search visibility; you need both.
What does Google Analytics 4 measure?
Google Analytics 4 is an event-based analytics tool that measures visitor behaviour through a tag placed on your site. GA4 reports how many users arrive from each channel, which pages they view, how engaged they are, and how often important events such as form submissions or WhatsApp clicks happen.
- —Acquisition: is traffic coming from organic search, ads, social or direct?
- —Engagement: page views, engagement rate, average engagement time.
- —Events and key events: in 2024 GA4 renamed 'conversions' to 'key events'; goals like forms, calls and quote requests live here.
- —Landing pages: the first page of each visit and how those pages perform.
What does Google Search Console measure?
Google Search Console is Google's free tool for site owners that shows how a site performs in Google Search. Search Console reports data from before the visitor lands on the site: impressions, clicks, click-through rate and average position. It also shows which pages are indexed, crawl problems and any manual actions.
- —Performance report: impressions, clicks, CTR and average position by query, page, country and device.
- —Page indexing report: which URLs are indexed and why others are excluded.
- —URL Inspection: how Google sees a single page, plus a request-indexing button.
- —Sitemaps: submitting sitemap.xml and seeing whether it was read.
- —Core Web Vitals, HTTPS, and manual actions / security issues reports.
Why don't the GA4 and Search Console numbers match?
GA4 and Search Console numbers not matching is normal, because the two tools count different things in different places. Search Console counts search clicks recorded on Google's servers, while GA4 only records a session when its tag runs in the visitor's browser and manages to send data. Declined consent, ad blockers and quick exits widen the gap.
- —Cookie consent: on a privacy-compliant site, visitors who decline analytics cookies are missing or limited in GA4, but Search Console still counts their click.
- —Ad blockers and browser privacy settings can block the GA4 tag.
- —A user who bounces before the page loads is a click in Search Console and nothing in GA4.
- —Search Console covers Google web search only; 'Organic Search' in GA4 also includes Bing, Yandex and others.
- —Search Console hides some rare queries for privacy and reports in Pacific Time.
- —A click is not a person: one user can click several times, while GA4 counts users and sessions separately.
Rule of thumb: watch trends, do not try to reconcile absolute numbers. If organic traffic moves in the same direction in both tools, your measurement is healthy.

Which tool answers which question?
Rather than choosing between GA4 and Search Console, open the right tool for the question at hand. Whether people find you on Google, with which words, and whether a page is indexed are Search Console questions; what visitors do once they arrive, whether they request a quote and which channel drives sales are GA4 questions.
- —'Is my new service page showing on Google?' → Search Console, URL Inspection.
- —'Which searches show my site but get no clicks?' → Search Console, Performance report.
- —'How many quote forms did organic visitors submit?' → GA4, key events.
- —'Do visitors from ads or from organic search convert better?' → GA4, traffic acquisition report.
- —'How fast is my site for real users?' → Search Console, Core Web Vitals report.
How do you link GA4 and Search Console?
GA4 and Search Console are linked by adding a Search Console link under Product links in the GA4 admin panel. The same Google account needs editor access to the GA4 property and owner access to the Search Console property. Once linked, Search Console data can be viewed inside GA4 reports.
- —In Search Console, create a Domain property where possible; it is verified with a DNS TXT record and covers http, https, www and subdomains in one place.
- —GA4 > Admin > Product links > Search Console links > Link.
- —After linking, publish the Search Console collection from Reports > Library in GA4, or the report will not appear in the menu.
- —If you run Google Ads, link GA4 to Google Ads too and import your key events.
What is the setup checklist for developers?
The GA4 and Search Console setup checklist for developers covers verification, loading the tag correctly, defining the important events and respecting cookie consent. Set up properly once, the business owner only has to read reports; set up badly, it leads to months of decisions based on wrong data.
- —Verify Search Console via DNS and submit the sitemap.xml URL.
- —Load the GA4 tag exactly once on every page; a duplicated tag doubles sessions.
- —In single-page apps, confirm with DebugView that route changes are measured as page_view events.
- —Define events such as form submissions, phone and WhatsApp clicks, and mark them as key events.
- —Filter your own office IP as internal traffic.
- —Set data retention to match your needs and privacy notice, and tie tags to cookie consent.

What should a business owner check every month?
Each month a business owner should check the click and impression trend, top queries and indexing errors in Search Console, and organic traffic, key event counts and the best-converting landing pages in GA4. A 20-30 minute monthly review is enough to spot problems before they grow.
- —Search Console: compare the last 28 days with the previous period; is there a sudden drop in clicks?
- —Search Console: queries with high impressions but low CTR are chances to improve titles and meta descriptions.
- —Search Console: any new errors or a rise in 'Crawled - currently not indexed' in the Page indexing report?
- —GA4: are users and key events from organic search growing?
- —GA4: which landing pages bring quote requests, and which get traffic without converting?
