Measure what matters, improve what converts
Web Analytics Agency and Google Analytics 4
Measure, understand and improve your business’s digital performance
Web analytics is not about accumulating data, but about turning it into decisions that grow your business. At our agency, we measure what really matters to understand how users interact with your website, detect what works and what doesn’t, and optimise every step of the journey to conversion.
At BIGSEO, we help you transform analytics into a strategic tool to improve results: more qualified leads, more sales and greater control over the performance of your digital ecosystem.

More than 10 years measuring the success of online businesses
Experience makes all the difference when it comes to interpreting data. At our agency, we have been analysing digital projects from different sectors, business models and levels of complexity for more than a decade.
We know what to measure, how to do it and, above all, how to convert that data into real improvements in performance and profitability.
A strategic and technical approach
Analytics requires a solid technical foundation, but also a strategic vision. At BIGSEO, we bring both worlds together so that measurement is aligned with business objectives.
We don’t just look at the data: we analyse it, contextualise it and turn it into concrete actions to improve your results.
We work closely with your marketing or development team
We adapt to your team’s way of working. We collaborate directly with marketing, development or product teams to ensure correct implementation and effective use of data.
Analytics is not a silo: it is a key part of your overall digital strategy.
What does professional web analytics offer you?
Reliable data for smarter decision-making
Poor measurement leads to poor decisions. We implement robust and accurate analytics systems so you can trust your data and use it as a basis for defining strategies, prioritising actions and optimising resources.
Identification of leakage points and opportunities for improvement
We analyse user behaviour to detect where conversions are being lost and what elements are slowing down the performance of your website or application. We convert these insights into clear opportunities for optimisation and growth.
Better performance in campaigns and conversion funnels
Well-configured analytics allow you to understand the real impact of your campaigns and acquisition channels. We measure the entire funnel to optimise acquisition, improve conversion, and maximise the value of each user.
Greater control over the ROI of your digital investment
Knowing which actions generate results and which do not is key to scaling your business. We help you measure the return on investment of your digital actions and focus your efforts where they really add value.

FAQs about analytics at the agency
We want to help you make an informed and valuable decision. We answer several common questions.
What are the differences between GA4 and Universal Analytics?
GA4 is the evolution of Universal Analytics. It is designed to provide a more comprehensive view of user behaviour across all your channels (web, app, etc.), with a measurement model based on events rather than sessions. It also allows for customised reports, better integration with BigQuery, and measurement that is more focused on the customer lifecycle. It is the current standard from Google.
What can you measure with Google Analytics 4?
Almost everything that happens on your website or app: visits, clicks, submitted forms, purchases, time on page, navigation paths, custom events, conversions, scrolling, video playback, button interactions, and much more. GA4 is very flexible and can be adapted to what really matters to your business.
How do I know if my measurement is reliable?
We audit your current implementation to detect errors, duplicates, or misconfigured events. We then correct or redo the measurement using best practices with Google Tag Manager and GA4, ensuring that the data reflects reality and does not lead to erroneous decisions.
What is an event and how is it configured?
Yes. All our projects include a review and adjustment phase after delivery to fine-tune the design, content and functionality. We also offer maintenance plans to ensure your website continues to evolve smoothly and is always up to date and secure.
Do I need technical knowledge to understand the data?
No. We create visual dashboards in Looker Studio (formerly Data Studio) that translate your metrics into clear insights focused on business objectives. In addition, we train and support you so that you and your team can make data-driven decisions without having to be analysts.
