It's not that you can own an emoji, but you can link emojis to your personal brand by constant repetition.

A great example is Katelyn Bourgoin (who also brands herself with yellow). Some of her tweets include the 🧠 emoji:

Slowly, this starts to build a presence in her audience’s head that the 🧠 emoji belongs to her.

This works because Katelyn uses it with a clear purpose, not just because.

She talks about Customer behavior and psychology, so using the 🧠 emoji makes a ton of sense for her and her brand.

If you want to own an emoji, make sure that it makes sense in the bigger context of your brand.

I, for example, am trying to own the 🕵️‍♂️ emoji because of The Steal Club.

🕵️‍♂️ How to steal it?

To effectively make an emoji your own, ensure it has a clear and relevant connection to your content.

Consistently and purposefully use this emoji in your posts to create a strong association between it and your online presence.
