TL;DR:
Web analytics is the practice of measuring and understanding website traffic: how many people visit, where they come from, which pages they see, and whether they take the actions you care about. It turns raw visits into decisions, what to build, what to write, where to spend. Modern privacy-first web analytics does this without cookies or personal data.
Web analytics answers a deceptively simple question: what is actually happening on my website? Not guesses about who is interested, but a measured account of who arrived, how they found you, what they looked at, and whether they did the thing you wanted. It is the feedback loop that turns a website from a guess into a system you can improve.
What web analytics measures
- Audience: how many visitors and sessions, and returning versus new.
- Acquisition: where visitors come from, search, social, referrals, campaigns.
- Behaviour: which pages they view, in what order, and where they leave.
- Conversions: whether they signed up, bought, or did what you care about.
The core metrics
| Metric | What it tells you |
|---|---|
| Visitors | How many distinct people came |
| Pageviews | How many pages were loaded |
| Sessions | How many visits (a run of activity) |
| Bounce rate | Share who left after one page |
| Sources | Where the traffic came from |
| Conversions | Who took a key action |
Traditional vs privacy-first web analytics
Traditional web analytics (Google Analytics being the archetype) uses cookies to recognise visitors over time, which is powerful but triggers consent banners and privacy questions. Privacy-first web analytics measures the same core things (visitors, sources, pages, conversions) without cookies or personal data, so it needs no banner. For most sites the privacy-first metrics are all they ever actually read.
Open Analytics is privacy-first web analytics: realtime, cookieless, with revenue attribution and an AI-queryable dataset.
See how it worksFrequently asked questions
- What is web analytics used for?
- To understand and improve a website: which marketing brings visitors, which pages hold attention or lose it, and whether people take the actions you care about. It replaces guesswork with measurement, so you can decide what to build, write and spend based on what actually happens.
- What is the difference between web analytics and product analytics?
- Web analytics measures website traffic and behaviour, visitors, sources, pages, conversions. Product analytics focuses on in-app user behaviour and events over time, usually for software products. They overlap on event tracking; web analytics leads with traffic and acquisition, product analytics with retention and feature use.
- Is web analytics legal without consent?
- Cookieless web analytics that stores no personal data needs no consent, because it falls outside the EU's ePrivacy and GDPR consent requirements. Cookie-based web analytics like Google Analytics generally does require consent. So the answer depends on whether the tool sets cookies.
