Measuring SEO: Which Question, Which Data? Why Search Console, GA4, Server Logs and CrUX Disagree
Search Console, GA4, server logs and CrUX count different parts of the same visit, so they give different numbers; the right number depends on the question you ask. We cover the question-metric-source mapping, why the numbers disagree, C# code that separates Google traffic in logs using Google's Referer rules, and the measurement options for mertozen.com.
Measuring On-Site Behavior with GA4: The Event Model, page_view in an Angular SPA, Custom Events and Key Events
In an Angular SPA you send page_view either through enhanced measurement's history tracking or by hand, never both; if you send it by hand, do it inside a TitleStrategy, because the router writes the title after NavigationEnd. We cover GA4's event model, key events, gtag with a CSP nonce in Razor pages, events that matter for a blog and Measurement Protocol code that sends no personal data.
Privacy and Consent in Analytics: The KVKK Cookie Guide, Consent Mode and Cookieless Alternatives
You do not load the analytics tag before consent, and when the consent rate changes, GA4's number drops without any change in traffic; you tell them apart with a source consent does not affect. We cover what the KVKK cookie guide means for measurement, ITrackingConsentFeature in ASP.NET Core, consent-gated loading in Angular, basic vs advanced Consent Mode, the 2026 change and cookieless alternatives. Not legal advice.
