Traffic increase, due multiple counts of same user.

[Gonzo2028]

Hello everybody,

thanks for this awesome lib, i was using ga4lite before to reduce the js footprint on my sites.
I now successfully implemented ga4mp, but i am having a strange issue now, it seems, that users are getting counted multiple times.
My site are single page applications
i am calling it as follows on the initial request:

async initAnalytics() { if (Webapp.getDevEnvironment() === true || Webapp.getGoogleAnalyticsStatus() === false || User.getAdminStatus() === true) { return; } await DomHandler.loadScript('/scripts/libs/ga4mp-0.0.8/ga4mp.umd.js'); window.ga4track = ga4mp(["{{ANALYTICS_ID}}"], { user_id: undefined, non_personalized_ads: true, debug: true, }); Webapp.sendPageViewToAnalytics(null); if (window.performance) { const duration = window.performance.timing.domContentLoadedEventEnd - window.performance.timing.navigationStart; ga4track.trackEvent('timing_complete', { 'name': 'load', 'value': duration, }) } }

every following "page_view" which is handled by navigation api or pushState (depending on browser)
I am just calling this:

static async sendPageViewToAnalytics(duration: number | null) { if (Webapp.getDevEnvironment() === true || Webapp.getGoogleAnalyticsStatus() === false) { return; } const fullReferrer = window.location.protocol + "//" + window.location.host + Webapp.getReferrer(); const fullUrl = window.location.href; ga4track.trackEvent('page_view', { page_location: fullUrl, page_referrer: (fullReferrer !== fullUrl ? fullReferrer : ''), page_title: document.title, language: Webapp.getCurrentLanguage() }); if (duration !== null) { ga4track.trackEvent('timing_complete', { 'name': 'load', 'value': duration }) } }

The code is currenlty running live here: https://mallorca-social-clubs.com/.
The requests "pings" are looking fine so far, they are exact the same amount i would expect.

Any ideas what i am doing wrong here or ist it a bug?
Sadly the documentation lacks a lot of information.

Every page refresh by browser reload, F5 or CTRA+Shift+R seems to count as a new user. I havent noticed this behaviour with gtag which i was using before (just like two weeks), before i had the old GA running wihout issues for years until Google stopped it.

Thanks in advance

Anyone?
I tried different implementations in my single page application, but it keeps counting same users multiple times and i have no idea why.

Same here. Since I use this library, me user counts are doubled.

This library does not account for session state. You need to manage the generation and updating of the clientId yourself to ensure accurate session and user counts.

@thyngster thanks, I know. I implemented a really simple use case, because all I need is pageview event. Nevermind, I solved it with @minimal-analytics/ga4 npm package.
