enhanced measurement

Enhanced measurement lives in the GA4 Admin under each web data stream. Flip it on and the Google tag starts sending a fixed set of event types with no developer work. The events are page_view, scroll, click (outbound only), view_search_results (site search), video_start / video_progress / video_complete (embedded YouTube), file_download, and form_start / form_submit.

What it captures, and what it misses

The convenience has hard edges. The scroll event fires once, at 90% page depth, so you cannot see who reached 25% or 50% without a custom Google Tag Manager trigger. Julius Fedorovicius of Analytics Mania notes that enhanced measurement only tracks that single 90% threshold, with no setting to change it. Form tracking is auto-detected and often unreliable: it can miss AJAX-submitted forms and fire on things that are not real submissions. Outbound click only counts links leaving your domain, and page_view on single-page apps can double-count or skip route changes depending on setup.

For SEO work the practical takeaway is that enhanced measurement gives you a fast, code-free baseline of engagement signals, but treat those numbers as directional. Anything you plan to report on or optimize toward (form completions, scroll milestones, real content depth) usually needs a deliberate GTM or gtag implementation on top. Verify each toggle matches how your site actually behaves before trusting the reports, and remember you need Editor access at the property level to change these settings.
