Matomo agency: your data, in-house and without cookies

We implement and manage Matomo so that you stop renting your analytics. The data is yours, unsampled, with full history and with the option to measure without asking for consent.

Even More Difficult

Why switch to Matomo?

For three reasons you will notice in the first month: the data is yours, it is not sampled and you can measure without cookies.

Let me explain. With Google Analytics 4 you do not have the data; you have access to it. Google decides how much history it keeps, samples when volume rises and makes you depend on cookie consent, which in Spain means losing between a third and half of your visits, depending on the sector. With Matomo the data lives on your server or on one of your choosing, it is kept in full and it can be configured in cookieless mode, exempt from the banner.

Clearly, it is not all advantages: Matomo has to be maintained, and for advertising integrations GA4 is still more convenient. We tell you so before migrating, not afterwards.

What do you gain by measuring with Matomo?

Basically, you recover the part of reality that you are not seeing today. These are the concrete effects:

Complete data, not a sample. Matomo does not sample, so your reports match reality even when traffic rises.

Measurement without a cookie banner. In cookieless mode you recover the traffic you are currently losing to consent rejection. It is the reason most of our clients end up migrating.

Compliance without surprises. The data does not leave your infrastructure, which makes the conversation with your data protection officer considerably simpler.

History that does not expire. You will be able to compare with three years ago without anyone having deleted the data under a retention policy.

How we work as a Matomo Analytics agency

Even More Difficult

How do we handle the implementation?

With the same rule we apply across all our digital analytics work: verify first, measure second, and never accept a figure without cross-checking it against a second source.

Diagnosis. We review what you measure today, what you are losing through consent and what decisions you need to be able to make. Without this, migrating means changing tools and keeping the problem.

Implementation and tagging. Installation, configuration of goals and events, and e-commerce tracking where applicable. We let Matomo run alongside whatever you already have for a few weeks: it is the only way to check the discrepancy between the two and find out how much traffic you were losing.

Reports and training. Dashboards built around the decisions your business makes and a session with your team, because a tool that only the agency understands is not much use.

Frequently asked questions

For data ownership and for what you stop losing.

Without mixing apples and oranges: GA4 is free, powerful and closely integrated with the Google ecosystem, and for many businesses it is enough. Matomo costs money and has to be maintained, but it gives you back three things GA4 does not: ownership of the data, no sampling and the option to measure without consent.

I would recommend deciding on the basis of your case, not ideology. If your traffic is high, if consent is eating up half your visits or if your sector is sensitive about data protection, Matomo usually pays off. If not, it may not be worth it for you.

Yes. It integrates with Google Tag Manager, with behaviour tools such as heatmaps and with external dashboards via API, as well as having its own.

The honest caveat is in advertising: the native integration with Google Ads is not the same as GA4’s. That is why, in accounts with heavy ad spend, we usually keep both running side by side, each for what it does well, and we explain this in digital analytics.

Between one and three weeks for a corporate website. An e-commerce site with a large catalogue and complex goals takes four or five.

That is why we always allow a period in which it runs alongside your previous tool. It is not excessive caution: the discrepancy between the two is precisely the most interesting figure in the whole migration, because it tells you how much you had not been seeing.

Yes, and that is where a good part of the value lies. Custom dimensions, your own goals, funnels, e-commerce tracking and dashboards built around your decisions rather than around the metrics the tool comes with as standard.

Yes. Matomo can be configured to measure without cookies, and in that mode European regulations do not require a consent banner for analytics.

The practical result is that you recover visits that you are simply not counting today. How many depends on your audience: in the projects we have migrated the difference has always been significant, and in some sectors it has completely changed how the channel is read.

With one honest caveat: without cookies you lose precision in recognising returning users. You gain real volume and lose some detail in tracking across sessions. For most businesses the trade-off is worth it, but it is good to know.
