To track the performance of your Smily website and measure the effectiveness of your marketing campaigns, you need to add two identifiers in the settings of the Website application in your Smily account:

  • Google Analytics 4 (GA4) key → to analyze traffic and conversions

  • Google Tag Manager (GTM) key → to manage your marketing tags

Important: Both keys must be added to ensure complete and reliable tracking of your website.

This guide explains how to obtain your identifiers and configure them on your Smily website.

Step 1: Get Your Google Analytics 4 (GA4) ID

Create Your GA4 Account

  1. Go to analytics.google.com

  2. Sign in with your Google account (or create one)

  3. Click Start measuring or Admin > Create Property

  4. Fill in the required information:

    • Property name: give your site a name (e.g. “My Rental Website”)

    • Time zone: select your time zone (e.g. Europe/Paris)

    • Currency: EUR

  5. Answer the questions about your business

  6. Accept the terms of service

Retrieve Your GA4 Measurement ID

Once your account is created:

  1. In Google Analytics 4, click Admin (gear icon at the bottom left)

  2. In the Property column, click Data streams

  3. Click Add stream > Web

  4. Enter your Smily website URL (e.g. yoursite.com)

  5. Give the stream a name (e.g. “Main Website”)

  6. Click Create stream

  7. Copy the Measurement ID that appears

Your GA4 Measurement ID starts with G- and looks like this:
G-XXXXXXXXXX

Step 2: Get Your Google Tag Manager (GTM) ID

Create Your GTM Account

  1. Go to tagmanager.google.com

  2. Sign in with your Google account (the same one used for GA4)

  3. Click Create account

  4. Fill in the information:

    • Account name: your company name

    • Country: select your country

  5. Configure the container:

    • Container name: your website URL (e.g. yoursite.com)

    • Target platform: Web

  6. Click Create

  7. Accept the terms of service

Retrieve Your GTM Container ID

After creation, Google Tag Manager will display a window with:

  • Your Container ID

  • Two code snippets (you do not need to copy them, Smily handles this)

Copy only the Container ID.

Your GTM ID starts with GTM- and looks like this:
GTM-XXXXXXX

You can close the window—you now have everything you need.

Step 3: Configure GA4 and GTM on Your Smily Website

Now that you have both IDs, it’s time to add them to your Smily website.

Access Your Website Settings

  1. Log in to the Website Application in Smily

  2. If you have multiple websites, select the one you want to configure

  3. In the menu, click Preferences

Add Your IDs

On the Preferences page, you will see two fields:

Zight 2026-1-5 at 17.13.49

1. Google Analytics 4 Field

  • Find the Google Analytics 4 field

  • Paste your GA4 ID (starting with G-)

  • Format: G-XXXXXXXXXX

2. Google Tag Manager Field

  • Find the Google Tag Manager field

  • Paste your GTM ID (starting with GTM-)

  • Format: GTM-XXXXXXX

3. Save

  • Click Save at the top of the page

That’s it! Tracking is now active on your Smily website. Both tools (GA4 and GTM) now work together to track your visitors and conversions.

Step 4: Enable Conversion Tracking (Optional)

To accurately track confirmed bookings as conversions in Google Analytics, you need to enable the redirection of the payment page to your own domain.

Required action: Contact Smily Support to request activation of the payment page redirection. This configuration allows GA4 to track conversions on your own domain.

Once enabled by support, your bookings will automatically be tracked as conversions in Google Analytics 4.

Check That Tracking Is Working

Check GA4

  1. Go back to your Google Analytics 4 account

  2. In the menu, click Reports > Realtime

  3. Open your Smily website in a new browser tab

  4. Browse a few pages of your site

  5. Return to GA4: you should see your visit appear in real time

If you see your visit, GA4 is working correctly! ✅

Check GTM

  • Install the free Chrome extension Tag Assistant (available in the Chrome Web Store)
    or

  • Use Preview mode in GTM:

    1. In your GTM account, click Preview (top right)

    2. Enter your Smily website URL

    3. A window will open showing active tags

If you see the GTM container, GTM is working correctly! ✅

Why Install Both Tools?

GA4 and GTM work together to provide complete tracking:

  • GA4 collects and analyzes your website data (visitors, page views, conversions)

  • GTM manages the installation of GA4 and all your other marketing tools (Facebook Pixel, Google Ads, etc.)

Without GTM, you won’t be able to easily add other tracking tools later.
Without GA4, you won’t have any data to analyze.

Both are required for effective tracking.

Frequently Asked Questions

Do I really need to install both?

Yes, absolutely. GA4 and GTM complement each other:

  • GA4 alone is not enough if you want to add other tools (Facebook, Google Ads)

  • GTM alone does not collect any data

For complete and scalable tracking, you must install both IDs on your Smily website.

How long does it take to see data?

  • Real-time: immediately (you can test right away)

  • Full reports: 24 to 48 hours to see complete data in GA4

Is it free?

Yes, Google Analytics 4 and Google Tag Manager are 100% free for standard use.

Is tracking GDPR-compliant?

Yes. Tracking only starts if visitors accept cookies via the consent widget. Make sure the cookie widget is properly installed on your Smily website (this is usually done by default).
