How to actually know which channel drove your traffic

You launch, you post in five places, and an hour later your visitor count jumps. Great. Now answer one question: which post did it? If you cannot, you are about to spend next week repeating the thing that did nothing and dropping the thing that worked.

This is the most common way founders waste their first month after launch. Not laziness, just missing plumbing. The fix takes ten minutes and changes every decision after it.

Tag every link you share

A UTM tag is a few words added to the end of a link that tells your analytics where the click came from. Same page, different label per place you post it. Your analytics then groups visitors by that label, so Reddit traffic and X traffic land in separate rows instead of one anonymous pile.

• Reddit: yoursite.com/?utm_source=reddit
• X post: yoursite.com/?utm_source=x
• Newsletter: yoursite.com/?utm_source=newsletter
• Cold email: yoursite.com/?utm_source=email

Keep the labels short and reuse the exact same spelling every time. "x" and "twitter" and "X" become three different rows, and now you are back to guessing.

Read sources, not just totals

A total visitor count tells you something happened. The sources breakdown tells you what to do next. Once a week, look at which labels brought real visitors, which brought people who actually signed up, and which brought a number that looked nice and did nothing else. Traffic that does not convert is not a win, it is a distraction wearing a costume.

That is the whole loop: tag what you share, read it by source, double down on what converts. Do that and your second month is aimed instead of scattered.
