The benefits of Google Analytics

Updated October 2026. This post first described Universal Analytics, the old version of Google Analytics. Google stopped processing data in standard Universal Analytics properties on July 1, 2023, and removed access to their old data from July 1, 2024. We’ve rewritten it for Google Analytics 4 (GA4), the version everyone uses now.

Your website is up and running. Now you need to know what’s working: who is coming, where they come from, what they read and whether they get in touch. That is what Google Analytics is for.

What Google Analytics shows you

Google Analytics 4 is a free tracking tool from Google. Its main reports are:

• Realtime: what people are doing on your site in the last 30 minutes. Handy for checking that tracking works, or that a newsletter or ad is sending visitors.
• Acquisition: how visitors arrive, for example from Google search, ads, social media, email, other websites or AI tools such as ChatGPT.
• Engagement: which pages people view, where they land first, and the events they trigger, such as clicks, scrolls and downloads.
• Key events: the actions that matter most to your business, such as a contact form send, a phone-number tap or a purchase. GA4 used to call these conversions. Google now uses “key events” in Analytics and keeps “conversions” for actions used to measure ads.
• User attributes and tech: visitors’ country, city, language, device and browser. Age, gender and interests appear only if you turn on Google signals, and Google hides small groups to protect privacy, as its demographics report guide explains.
• Monetization: sales and revenue, if you run an online store.

One number works differently from the old version. In GA4, bounce rate is the share of visits that weren’t “engaged”: visits that lasted 10 seconds or less, viewed one page and triggered no key event. It is the opposite of the engagement rate, which is the more useful number to watch.

Why you should be using it

A great website is only half the job. The other half is learning what keeps visitors interested and what brings them back, so you can do more of what works and change what doesn’t. Without data, you’re guessing. Here are five reasons to start.

1. 1 – It’s free

   The standard version of Google Analytics costs nothing. There is a paid version, Analytics 360, for large organizations. For what it tells you, it’s one of the best bargains you can make.

2. 2 – Get to know your visitors, maximize your reach

   Who’s visiting your website, from where, and on what devices? Different groups want slightly different things from your business. If most of your visitors are on phones, the mobile version of your site is the one that matters most. If a growing share comes from another city or country, that might be a market worth serving.

3. 3 – Learn about your website’s channels

   How did your visitors get to your website? A Google search? A business directory? A Facebook ad? An answer in ChatGPT? Google Analytics shows how people find their way to your site, so you can put more into the channels that bring the most visitors and enquiries. Connect Search Console as well, and you can see which Google searches bring people to which pages.

4. 4 – What are your visitors doing?

   Once people reach your site, it helps to know what they do there: which pages they read, which pages lead to an enquiry, and where they leave. That shows you where to improve, whether it’s a page people abandon or a contact form they never reach.

5. 5 – See the effect of what you do

   Compare any period with another: this month against last month, or the weeks after a campaign against the weeks before. That shows you which campaigns, posts and changes made a difference, and the Realtime report confirms that a launch or newsletter is working as it happens.

Set it up so the numbers mean something

• Mark your key events. Decide which actions count as success, such as form sends, calls and purchases, and mark them as key events. Without them, Analytics can tell you how many people came but not whether the site did its job.
• Check the numbers against reality. Bots and form spam can inflate visits and key events. If Analytics says ten people sent the contact form this month, check that ten real enquiries arrived.
• Link Search Console, so you can see search queries next to what visitors did.
• Look every month, at the same few reports, and write down one thing to change.

A Real Game Changer

Google Analytics is one of the most useful free tools a business website can have, as long as it is set up to measure what matters to you. It turns “we think the site is working” into “we know which pages bring enquiries”.

It is also the starting point for search work: our SEO and AI search page explains how we use Analytics and Search Console to decide what to improve. Get in touch with Millennial Web Development if you’d like help setting up Google Analytics on your site.
