What are data analytics?

Data analytics is the boring superpower: take a pile of events and decide what to do on Tuesday. Not a dashboard for the board. A sentence that says which page made a customer.

Definition

Data analytics is collecting events, cleaning the mess, and turning them into a decision. Pageviews are not analytics. “This URL made $400 and this one made $0” is analytics.

If you cannot change behavior with the number, you built interior design. Pretty charts. No steering wheel.

The four types, in human

  1. Descriptive: what happened. Traffic, revenue, unsubscribes. Start here. Stay here longer than the course told you to.
  2. Diagnostic: why. That landing page converted because the ad matched the H1. That one died because you asked for a phone number.
  3. Predictive: what might happen. Fine when you have history. Comedy when you have 40 users and a neural net.
  4. Prescriptive: what to do. “Kill the channel. Double the swap. Change the button.” This is the point. Everything else is homework.

What to track if you ship on the internet

  • Unique visitors to each campaign URL.
  • The conversion the page promised (email, trial, purchase).
  • Revenue or kept subscribers, not just joins.
  • Where they came from, without lying to UTM parameters.

That is enough to run a funnel. Vanity: bounce rate you do not understand, “engagement,” a heat map of people rage-clicking your logo.

I use DataFast when the question is “which article made a customer.” Affiliate link. The review is here. Google Analytics can count. It is worse at the money sentence.

How people lie with analytics

  • Reporting sessions as humans.
  • Counting waitlist emails as customers.
  • Ignoring refunds.
  • Changing the definition of “active” the week the chart looks bad.
  • A/B testing a button color with 70 visitors and calling it science.

If you are building in public, post a number you would still defend on a bad week.

A weekly ritual that fits in twenty minutes

Pick one question. “Which source sent keeping subscribers?” Open the tool. Write one sentence. Do one thing. Close the laptop. Analytics as a hobby is how you avoid shipping Tuesday’s issue.

For a list, watch who is still there on day 14. For a product, watch who paid and did not refund. For SEO, watch which URLs get impressions with no page — then write the page. That is why this one exists.

FAQ

Do I need a data team?

No. You need unique URLs and one conversion. Hire analysts after you have a question they cannot answer in a spreadsheet.

Is Google Analytics enough?

It is enough to see traffic. It is not enough if you care which blog post made a sale. Pair it with something that sees revenue.

What’s a good conversion rate?

Depends on the traffic. Compare against yourself. Screenshots on Twitter are not a benchmark.
