Switch from Google Analytics

misomoon imports a Google Analytics 4 property straight from Google, so your daily history moves without export files. Your tracking calls keep their event names: gtag('event', 'sign_up', { method: 'email' }) becomes misomoon('sign_up', { props: { method: 'email' } }), and the purchase event carries revenue. Revenue history, key events, and Universal Analytics data stay behind.

#Add misomoon next to Google Analytics

1. Add your site in misomoon and paste its script tag into the <head> of every page, next to the Google tag (Track your site). If Google Tag Manager loads your Google tag, add misomoon there instead (Install with Google Tag Manager).
2. Leave both on for a week or two, until misomoon's numbers look right to you.

#Replace Google Analytics' calls

misomoon counts pageviews by itself, route changes in single-page apps included, so gtag('config', 'TAG_ID') needs no replacement. For each event, keep its name and move its parameters into props. A property value is a string, a number, or a boolean, and an event keeps up to 30 of them.

Keep Google's event names, such as sign_up and purchase. The import brings your events under those names, so the days before and after the switch add up under one name.

misomoon takes amount in the currency's major units, the same as Google's value. Each site has one reporting currency, and revenue in another currency stays out of the totals (Track revenue). If a payment provider's webhook reports your sales, connect it and leave revenue out of purchase, or each sale counts twice. For events your server sends, use the Node SDK (Send events from your server).

Key events don't move. Add each one again as a goal in Settings > Goals (Create a goal). A goal counts the events misomoon already collected, so you can add it at any time.

#Move Google Tag Manager tags

Keep your site's dataLayer pushes as they are, and add misomoon's tags next to the GA4 ones:

1. Create a Custom HTML tag with the trigger All Pages. Paste the queue line and the script tag, so calls made before m.js loads wait for it:

   htmlCopy

   <script>window.misomoon = window.misomoon || function () { (misomoon.q = misomoon.q || []).push(arguments) }</script>
   <script defer src="https://analytics.example.com/m.js?s=your-site"></script>

2. For each GA4 Event tag except purchase, create a Custom HTML tag with the same trigger that calls misomoon with the same event name, such as <script>misomoon('sign_up')</script>.

3. Submit and publish the container.

For a purchase that your page pushes to the dataLayer, call misomoon next to the push, with the same values:

dataLayer.push({ ecommerce: null })
dataLayer.push({ event: 'purchase', ecommerce: { transaction_id: 'T_12345', value: 72.05, currency: 'USD' } })
misomoon('purchase', { revenue: { amount: 72.05, currency: 'USD' }, props: { transaction_id: 'T_12345' } })

#Bring your history

Use misomoon's Google import. Follow Import a Google Analytics property, and leave To empty. The import ends the day before misomoon started counting (Days that count once).

The import fills the top-line numbers, the chart, channels, sources, referrers, UTM tags, pages, entry pages, countries, regions, cities, browsers, operating systems, devices, and custom events (What imported data fills). Imported days appear only in reports without filters. Google's own page_view, session_start, first_visit, user_engagement, and scroll events stay out, because misomoon measures them itself. Google's click, file_download, and form_submit become Outbound link, Download, and Form sent.

If the import shows Failed:, or you picked the wrong dates, delete the import and run it again.

Universal Analytics data is gone. Google shut Universal Analytics down, its API included, from the week of July 1, 2024. A report you downloaded from it before then can come in only as a CSV upload that you rewrite in misomoon's CSV format. Upload it after your GA4 import, so misomoon skips any day the GA4 import already holds.

#Remove Google Analytics

Once the import shows in misomoon, remove the Google tag and your gtag() calls. With Google Tag Manager, pause the Google tag and the GA4 Event tags, then publish the container. To keep seeing the Google searches that bring people to the site, connect Search Console, which doesn't need Google Analytics.

#What stays behind

• Revenue and ecommerce history. misomoon's imports fill no revenue.
• Key events. An import fills no goal conversions, so add the goals again.
• Event parameters. The import brings each event's count and visitors, not its parameters.
• Exit pages, browser versions, and scroll depth. The Google import fills none of them.
• Funnels, paths, and behavior. The Funnels, Paths, Behavior, and Speed views show only what misomoon collected.
• misomoon's bounce rule on imported days. From Google, a bounce is a session that wasn't engaged. misomoon's own data counts a visit with one pageview and no interaction.
• Universal Analytics data, unless you saved reports before July 2024.
