I have a pet peeve: I hate non-clickable links. Can’t stand them. I find them annoying and atrocious. And I’m not the only one. In fact it’s so common that there’s a term for expecting something should link (or do any action based on how it looks). It’s called an affordance.
To be fair, a “non-clickable link” is an oxymoron. However, I assume that any text on a website that references another page will link to it. It might be an email address, a page title, or a navigation tag – but sometimes there’s no way to click it. To me, this isn’t text. It’s a non-clickable link.
The reason I assume the text is clickable is because text referencing other pages is an affordance.
