How do I set up a GA4 property and web data stream?

The short version

• Use a Google Account the business owns. Never your web company’s or a staff member’s personal Gmail.
• Admin, then Create, then Account. Name the account after your business.
• Name the property, and set the right time zone and currency.
• Add a Web data stream with your site’s address. Review enhanced measurement before data starts.
• Copy the Measurement ID (G-) and add the Google tag to your site.

Before you start

Check whether Analytics already exists. A past web company may have set it up. Search old emails for “Google Analytics,” and ask whoever built your site. If a property exists and you can’t get in, our help article on seeing your visitor numbers explains how to get access. Creating a second property starts from zero and splits your data.

Decide which Google Account will own it. Our answer on which logins your business should own explains why it should belong to the business. A Google Workspace account or a Gmail address used only for the business both work.

How do I create the account and property?

These steps follow Google’s setup page.

1. Go to analytics.google.com and sign in. If it’s your first time, select Start measuring.
2. If you already have an account, open Admin, select Create, then Account.
3. Enter an Account name, usually your business name.
4. Review the data-sharing settings and choose the ones you’re comfortable with. Select Next.
5. Enter a Property name, such as your website’s name.
6. Choose your Reporting time zone and Currency. Analytics uses the time zone to decide which day a visit counts on.
7. Select Next. Choose your industry and business size.
8. Select Next. Choose how you plan to use Analytics. Google uses this to pick which reports you see first.
9. Select Create and accept the Terms of Service and Data Processing Amendment.

How do I add the web data stream?

1. When asked to start collecting data, choose Web. Later, you can find this in Admin, under Data collection and modification, then Data streams, then Add stream, then Web.
2. Enter your website’s main address, such as https://yourbusiness.com.
3. Enter a Stream name, such as “Website.”
4. Review Enhanced measurement. Google’s enhanced measurement page says it collects page views, scrolls, outbound clicks, site search, YouTube video plays, file downloads and form interactions without extra code. The same page says you must make sure no personally identifiable information is collected. If your site puts names, emails or phone numbers into page addresses or search terms, such as on a thank-you page, select the settings icon and turn off the options that would pick them up, or fix the site first. Check your cookie consent setup too; our guide to measuring with fewer cookies covers it.
5. Select Create stream.
6. On the stream details page, copy the Measurement ID. It starts with G-.

You’ll paste this ID, or the full Google tag, into your website. Our guide to adding GA4 to your website covers WordPress, website builders and Tag Manager.

What should I set straight after?

Do these on day one, before data starts piling up:

• Data retention: the default keeps detailed data for 2 months, and you can choose 14. It only affects Explorations and funnel reports, per Google’s data retention page. Our guide to measuring with fewer cookies covers the privacy side of the choice.
• Internal traffic: filter out your office. See stopping GA4 counting your own visits.
• A second administrator: add a trusted person in your business, so you’re never locked out. Our help article on adding users lists the roles.
• Key events: mark your form submissions and phone taps. See setting up key events.
• Search Console: link it once the tag is working. See linking Search Console to GA4.

Why does the setup matter?

Mistakes at this stage stick. The owner account decides who controls years of data. A wrong time zone shifts every day’s numbers. A second stream for the same site splits your visits in two. Ten careful minutes now saves untangling it later.

What are the common mistakes?

• Setting it up under the web company’s account. If you part ways, you can lose the data. Add them as a user instead.
• One property per page or per campaign. For a typical small business, one website gets one property and one web stream. Google allows more, but splitting a single site makes reports harder to read.
• A separate property for the www and non-www versions. One stream covers your site. Pick the address visitors actually see.
• Creating a new property because you can’t get into the old one. Try to recover access first, so you keep the history.
• Forgetting retention. Explorations can’t look back further than the setting, so decide on 2 or 14 months on day one.

What if I don’t see Admin or Create?

• Can’t find Admin: it’s the gear icon at the bottom left. If it’s missing, check you’re signed in to the right Google Account.
• Admin opens but Create is missing or greyed out: your role isn’t high enough. Google says creating a property needs the Editor role on the account. Ask an Administrator to change your role.
• “Start measuring” doesn’t appear: you already have an account. Use Admin, then Create.
• You can’t find the Measurement ID later: go to Admin, then Data streams, select your web stream, and look under Stream details.

How much does it cost, and how long does it take?

GA4 is free. Creating the account, property and stream takes about 10 minutes. Data can take up to 30 minutes to start after the tag is on your site, per Google’s setup page.

How does E-3 handle this?

Accounts E-3 sets up are created in the client’s name, with E-3 added as a user, so the data always stays theirs. Our SEO and AI search service includes this setup.
