A URL that opens is not a page that can be found. What "publish" hides.

I was looking at a place to put a page. It asked for no account, it took markdown, and it gave me a working link in a few seconds. I was about to keep it on my list of places that publish instantly when I read one line in its own description of itself: published pages are unlisted. I opened the link again. It worked. It looked like every other published page I have. And it was, for my purpose, worth nothing, because my purpose was for a stranger to arrive, and an unlisted page is one that no stranger can find.

Two things that feel like one

A working URL and a findable page feel identical when you hold the link in your hand. You paste it to a friend, it opens, the words are there, the page is public in the only sense you tested. But there are two different properties hiding under the one word, and they come apart exactly when you stop being the person with the link and start being the person who does not have it yet.

The first property is that anyone who already has the address can open it. The second is that someone who does not have the address can discover it, because a search engine was allowed to read it, keep it, and offer it in an answer. The first is a private door you can hand keys to. The second is a door on a public street with a sign a passer by can read. An unlisted page has the first and not the second. For sending a link to one person, the first is all you need. For being found by people you will never meet, the first is nothing at all.

Why the word blurs them

The confusion is built into the word publish, which names two acts as if they were one. One act is to make a page exist at an address. The other is to let the page be discovered by someone who was not told the address. A lot of tools do the first and quietly skip the second, sometimes as a feature, privacy by default, sometimes just because the first is easy and the second is a decision they did not make. And because the link they hand you opens, nothing on your screen tells you which of the two acts happened. The page that will never rank looks exactly like the page that will.

How to tell which one you got

You cannot tell by looking at the page while logged in, because your session sees everything. You tell by reading the page as a stranger would, with no account, and by asking two small questions. Does the page carry an instruction that asks search engines to skip it, the quiet tag that says do not index this. And is the page linked from anywhere a search engine actually walks, a list, an index, a feed, or is it an island that only exists at the end of a link you were handed. If the answer is a skip instruction and an island, the link is a private door. If the answer is no skip instruction and a path leading in, it is a public street.

What I do about it

I publish where a page is born findable, and I check each one as a stranger before I count it as done, because a page nobody can find is a draft with extra steps. It is a strangely easy thing to get wrong, because the reward for publishing, the link that opens, arrives immediately, and the thing you actually wanted, a person who was searching and arrived, arrives later or not at all, and never announces which page it came from. So it is tempting to treat the link as the finish line. It is not the finish line. It is the receipt for having started.

The general shape

The value of publishing is discovery, not the existence of an address. When a system hands you a URL, it has proven the easy half and said nothing about the half you cared about. The honest measure of a published page is not that it opens, which every page does, but that a stranger with a question can be led to it, which most pages cannot. Measure the thing you want, arrivals from people who were not told where to look, and treat a working link as what it is, a necessary step that on its own means very little.

I build BlueTicks for Gmail, a Chrome and Firefox extension that shows WhatsApp style ticks in your Gmail sent list, one tick sent and two blue ticks opened. Everything above comes from distributing it in public and caring whether a page can be found and not only opened. It costs 4 dollars a year, and the free tier covers 30 emails a month. You can find it at blueticks.io.
