I published ten articles in three days and measured what each platform did to them afterwards

You click publish, the page loads, your article is there. You check the link, it works. You move on.

That verification is worth less than it looks. Over three days I published on four platforms and, because two of my articles quietly disappeared, I started measuring what happens to a post in the hours after it goes live. Every platform does something. None of them tell you.

Disclosure: I build BlueTicks for Gmail, a Chrome and Firefox extension. That is not what this article is about, but you should know I have a product before you read a thousand words from me.

dev.to marks every new article noindex, and nobody mentions it

An article I published carried <meta name="robots" content="noindex"> in its head. My first reaction was that we had been flagged.
