Reading your referrer list without fooling yourself

The referrer list is the part of your statistics that looks the most like insight and misleads the most reliably. It is a list of the places people came from. Reading it correctly takes about two minutes of knowing what it is not.

What is recorded

The domain only. Not the page, not the full link, not whatever a campaign or a search engine appended to the end of it.

That is a deliberate limit and it is the same trade made everywhere else here — but it does limit you as well. The list will tell you that a forum sent you 300 people. It will not tell you which thread. That part you have to go and find.

And a visit with no referrer at all produces no row. Somebody arriving from a mail client, a chat app, a PDF, or a browser configured not to send referrers is not "direct traffic" in your list — they are simply absent from it.

Trap one: a big domain is not a big fan

Across every counter on this site, the most common referrer domain appears in the lists of 479 different websites. It is not the case that one platform is enthusiastically linking to 479 people. It is a platform where a lot of pages live, each with its own counter, each recording its own host as the place its visitors came from.

The second most common is a search engine, appearing for 130 sites, which is what a search engine ought to look like.

The general rule: if a domain shows up for everybody, it is infrastructure. If it shows up for you, it is a link.

Trap two: one row is not a trend

Of the 564 distinct domains recorded here, 474 appear for exactly one site. That is the normal shape of a referrer list: mostly single relationships. One forum, one directory, one friend's blogroll.

This is worth internalising before you start drawing conclusions from a list of ten domains with small numbers next to them. That is not a traffic mix. It is ten separate one-off events that happen to be printed in the same table.

Trap three: your own site is in there

Some of the rows are your own domain. That is not visitors arriving — it is people already on your site moving from one page to another, with the previous page reported as the referrer.

It is easy to miss because it usually sits near the top, and it inflates exactly the number people most want to see go up. Find your own domain in the list and mentally set it aside before reading the rest.

What the list is actually good for

One thing, mainly, and it is worth the whole feature: noticing that somebody linked to you, while it is still happening.

A domain that was not there last week and is now near the top is a live link with people coming through it. That is the window in which you can go and find the thread, answer the question being asked about your project, thank whoever posted it, or publish the follow-up while anyone is still paying attention.

A week later it is a row in a table. The referrer list is not a report to be read at leisure — it is closer to a doorbell.
