# Tracking launch day traffic so the numbers mean something

> Before launching, build every tagged link at once, define one conversion event, verify the event actually fires, and record a baseline. Then measure sessions by source, conversion rate by source, and how much traffic is still landing in direct. The largest source almost always converts worst.

Launch day produces a traffic spike and, for most people, no usable information. A few hours of setup beforehand turns it into the most informative day your product will have for months.

## Before you post anything

**Build and store every tagged link.** All of them, at once, in one note. Building links ad hoc while posting is where inconsistent casing gets in, and inconsistent casing cannot be fixed retroactively.

Free tool: [UTM Builder](https://rankcert.com/tools/utm-builder) - Build tagged campaign URLs with consistent utm_source, utm_medium and utm_campaign values so your launch traffic is actually attributable.

**Define one conversion event.** Signup, or trial start, or whatever the real goal is. One event. Traffic without a conversion denominator tells you nothing about quality.

**Check your analytics actually fires.** Load your own site in a private window and confirm the event arrives. The number of launches that produce no data because a script was blocked by a consent banner is not small.

**Set a baseline.** Note yesterday's sessions and signups. Without it you cannot tell what the launch added.

**Check the page you are sending people to.** Load it on a phone, on mobile data. Launch traffic is heavily mobile, and a hero image that takes six seconds costs you most of it.

## What to actually measure

Three numbers, in this order:

**1. Sessions by source.** Which post sent people. Straightforward, and the only one most people look at.

**2. Conversion rate by source.** Sessions to your one event, split by source. This is the number that matters, and it is almost always inverted from volume.

**3. Sessions still attributed to direct.** If this is large, you missed tags, or something stripped them. Some mobile apps strip query strings on outbound links, so a chunk of direct is normal - but half your traffic in direct means a tagging failure.

Ignore bounce rate, time on page, and pages per session on launch day. A spike of curious visitors distorts all three and they tell you nothing actionable.

## The finding you should expect

The channel that sends the most traffic almost always converts the worst.

A big aggregator sends a thousand curious visitors who convert at half a percent. A newsletter with four hundred subscribers sends eighty people who convert at fifteen percent. The second one is worth more, and you would never know from a traffic chart.

This matters because it tells you where to spend the *next* six months. Launch day is not a growth channel - it is one day. Its real value is telling you which audience actually wants the product.

## Offline and QR

If you are launching at an event or with print, generate a QR code pointing at a tagged URL. It is the only way that traffic gets attributed at all.

Free tool: [QR Code Generator](https://rankcert.com/tools/qr-code-generator) - Generate a QR code for any URL or text with adjustable error correction, and download it as a high-resolution PNG. No signup, no tracking, no expiry.

Use `utm_medium=qr` and a source naming the specific placement, so two posters in different rooms are distinguishable.

## The week after

Launch traffic decays fast - typically 80% of it in the first 48 hours. What you want from the week after:

**Which source sent people who came back.** Returning visitors from a source are worth far more than first sessions.

**What people searched for on your site.** If you have site search, the queries from launch week are the clearest product feedback you will get all quarter.

**Where they dropped off.** If a thousand people hit the signup page and forty finished, the problem is the form, not the traffic.

**Which pages they read besides the landing page.** Tells you what they needed to know before deciding.

Write down what you expect before launch day: which source will send the most, and which will convert best. Being wrong about the second one is the most useful thing you will learn.
