Your top mentions and hashtags will give brands an idea of what you usually post about and whether you’ve collaborated with any of their competitors.
Brands want to work with creators who post about topics relevant to their brand because you’ll likely have followers who are interested in their products. For example, if the brand is an outdoor hiking brand, they'll want to collaborate with a creator who posts about outdoor hiking topics.
