Site Search

Site search is a GA4 enhanced measurement event, and the view_search_results event is automatically triggered when a visitor enters a search term in the site's internal search box. The collected search_term parameter can be used to determine the information visitors are looking for and use it to establish a content strategy.

Site search in GA4 Enhanced Measurement automatically fires the view_search_results event when a URL includes search term parameters. By default, URL parameter names such as q, s, search, query, and keyword are automatically detected, and if other parameter names are used, they must be entered directly in the enhanced measurement settings. Collected search terms are recorded as the search_term parameter.

Site search data is very useful for your content strategy. By identifying the keywords that visitors frequently search for, you can find out what information the current site cannot provide, and based on this, you can plan new content or improve navigation.

In UA, you must register parameters in Management → View Settings → Site Search Settings to activate the search report. GA4 has automated this with enhanced measurement toggles, but there are times when URL parameter names need to be set manually.

GA4 screen path: Administration → Data Streams → Enhanced Measurements → Toggle ‘Site Search’ and enter parameter name. You can check popular search terms using the view_search_results event and search_term parameter in the Report → Event tab.

weballin practice perspective: Site search data on hospital sites directly shows the information patients are looking for. Frequently searched topics, such as 'double eyelid cost', 'anesthesia method', and 'recovery period', can be developed into separate FAQs or content pages to improve SEO and user experience at the same time.

Frequently asked questions

Why is the site search event not being captured?

If the site search is JavaScript-based rather than URL parameter-based (displaying search results dynamically without changing the URL), automatic detection is not possible with enhanced measurement. In this case, you must separately set up a custom event in GTM that sends the search event when the user clicks the search button or submits the form.

Where can I check site search data?

If you click the view_search_results event in the Report → Event tab, you can see a list of search_term parameter values. If you register search_term as a custom dimension in exploratory analysis, you can analyze the conversion rate and bounce rate for each search term in detail.
