GA4 vs Matomo vs Plausible: Which Suits a UK Site in 2026

Quick answer

For most UK small businesses, GA4 is the sensible default: it costs £0 and links straight to Google Ads and Search Console. Choose Plausible if you want simple, cookie-free numbers on one page for a small monthly fee. Choose Matomo if you want full control and are happy to self-host it or pay for its cloud version.

This guide compares the three on cost, privacy, ease of use and what each is genuinely good at, then gives a quick way to decide based on how your business actually wins customers.

What each tool is

Google Analytics 4 (GA4) is Google’s free analytics platform and the one most websites already have installed. It tracks visits, traffic sources, pages and actions such as form submissions and purchases, and it connects to Google Ads so you can see which ads bring enquiries.

Plausible is a lightweight, privacy-focused alternative. Its website describes it as using no cookies and no persistent identifiers, with visitor data processed on servers owned by European companies that never leaves the EU. The code is open source, so it can be self-hosted.

Matomo is a full-featured analytics platform designed as an alternative to Google Analytics, which you can install on your own server for free or pay to have hosted. It sits between the other two: more depth than Plausible, more control over your data than GA4.

GA4 vs Matomo vs Plausible at a glance

What they cost

At the time of writing, November 2026, the published prices were as follows. Prices change, so check each page before signing up.

• GA4: free for standard properties. Google also sells an enterprise version, which small businesses do not need.
• Plausible: its site lists Starter at $9 a month, Growth at $14 and Business at $19, with two months free on yearly billing and a 30-day free trial.
• Matomo: its pricing page lists the self-hosted On-Premise version as free forever, and Cloud plans from 29 a month before tax. Paid add-on bundles for self-hosting are priced separately.

“Free” self-hosting is not quite free. It needs a server, updates and someone to look after it. If your website is on managed hosting, ask whether a self-hosted analytics tool can run alongside it.

Privacy and cookie consent

Under UK law, storing or reading information on a visitor’s device, which includes most analytics cookies, normally needs consent. Since 5 February 2026, the amended Privacy and Electronic Communications Regulations include an exception for statistics. Schedule A1 allows storage or access where the sole purpose is collecting statistics about how the service is used in order to improve it, visitors get clear information about it and a simple, free way to object, and any sharing is only to help improve the service.

What that means in practice:

• Plausible says it uses no cookies at all, so the cookie question largely falls away, though you should still describe it in your privacy notice.
• Matomo can be configured to run without cookies or with tightly limited data, which can fit the statistics exception when set up carefully.
• GA4 uses cookies by default and sends data to Google. If you link it to advertising features, it is doing more than statistics, so a consent banner remains the safe approach.

This is a summary, not legal advice. If your sector handles sensitive data, take advice before choosing.

Where GA4 wins

• Google Ads: conversions flow straight back to your campaigns, which helps automated bidding find more enquiries.
• Search Console link: see search terms and landing pages in one place.
• E-commerce tracking: product views, baskets and purchases with revenue.
• Price: nothing to pay, whatever your traffic.

The downsides are real: it is hard to learn, reports hide in menus, and with a consent banner you will see fewer visits than really happened, because people who decline are not counted. GA4 also keeps user-level data for either 2 or 14 months, according to Google’s data retention help page, so set it to 14 months on day one if you want year-on-year comparisons.

Where Plausible and Matomo win

Plausible suits a trade or local service business that wants to know three things each month: how many people visited, where they came from and which pages they looked at. The whole dashboard fits on one screen, and the script is small, which helps page speed. Our guide to website speed for small businesses explains why that matters.

Matomo suits businesses that want GA4-style depth with the data kept on their own server, such as clinics, solicitors or firms with strict client confidentiality, and that have a developer or a host who can manage it.

Which one should you choose?

You can also run two at once. Some businesses keep GA4 for advertising data and Plausible for a quick, honest view of traffic. Just mention both in your privacy notice.

A worked example: two businesses, two answers

A roofing firm in Kent spends a few hundred pounds a month on Google Ads and gets most of its work by phone. For them, GA4 is the clear choice. Calls from the website and form submissions can be marked as key events and sent back to Google Ads, which lets the campaigns learn which searches turn into jobs. Without that link, the ads are optimised for clicks rather than calls, which is how small budgets get wasted. The cost is learning GA4 well enough to read two or three reports each month, or having someone do it for them.

A wedding florist in the Cotswolds runs no ads at all. Her enquiries come from Instagram, Google searches for her name and recommendations from venues. She wants to know whether people find her gallery pages and which venues’ websites send visitors. Plausible gives her that on one screen, with no banner covering her photography and no menus to learn. For her, the small monthly fee buys something GA4 does not: numbers she will actually look at.

Neither choice is wrong. The right tool is the one that answers the questions your business actually asks, and that someone in the business will open every month.

Switching tools later

Historic data does not move between tools, so a switch means starting a fresh baseline. If you are thinking of changing, run the new tool alongside the old one for a month or two, compare the numbers, then remove the old script. Expect the totals to differ: each tool counts visitors slightly differently, and consent banners hide some visits from GA4 that a cookie-free tool may still see.

Setting up whichever you choose

1. Install the tracking code once, site-wide, preferably through your theme or a tag manager rather than several plugins.
2. Exclude your own visits and your team’s, so internal browsing does not inflate the numbers.
3. Set up goals or key events: form submissions, phone link taps, bookings, purchases.
4. Test each goal yourself on a phone, using mobile data.
5. Write down your starting numbers so you can compare in three months.
6. Book a monthly 20-minute check in your calendar.

If your numbers fall suddenly after a change, our guide to sudden traffic drops helps you work out whether the problem is real or a tracking fault.
