I haven't tested this theory, but I have a feeling users of my website may believe that the 'Concept' tag is clickable, when it isn't. How can I make it clear that this is not a button?
We don't have the larger context of your problem, so here's some quick thoughts:
You could try making an element that looks more like a banner (or a bookmark). If you want to reduce the visual noise, you can make it a bit more subtle, so the other content stands out. You can use a lighter font so it's distinct from the actual content.
Here's a version w/ lighter and tucked completely into the corner, and one where you don't put any borders, just a simple gray text.
Here's another way to think of the issue, that comes in two steps:
- what do people think should happen when they click on [Concept]?
- can you implement that?
If people click it, most likely they're hoping to sort of "zoom in", to somehow get more details about the tag content. So maybe you can show a list of everything that's tagged with "Concept". But if all you can do is show a little pop-up defining what a "Concept" is, that's still granting the user some extra detail.
