Hi, could someone please help me identify my true niche?

Currently, I have two clients:

Client A: - I edit both long-form and short-form videos. - I create captions and thumbnails as needed. - I handle posting their videos across all their social media accounts. - I track their analytics. - I transcribe their voice messages and organize them in a spreadsheet.

Client B: - I manage TikTok content for three of his accounts. - I oversee a team of editors. - I review and provide feedback on the edited videos. - I handle TikTok ad campaigns. - I produce some of the TikTok videos. - I create captions for all TikTok content. - Previously, I managed their TikTok shop, but now we only focus on affiliate marketing.

I find that I enjoy my work with Client B more. However, I'm unsure whether I should classify myself as a social media manager, project manager, or online store manager.

Please help me in specifying my niche so I can offer my services to other potential clients. Thank you!! 🥺
