I've had some success rebuilding my audience after losing a big chunk of it. Whereas much of my content was once repinning, I'm now back to 75% of my 2019 audience by posting mostly original pins, using stories & movies, pinning less often, and focusing on fewer boards. Essentially I've narrowed my content offering to find an audience that is more likely to covert. I did this on the hunch that business accounts are being treated differently now than other accounts and that in order to drive metrics upward much of your pins need to be originals. Essentially I've made the transition from a curator account to a creator account. Success, however, likely lies in a balance between offering your own content and repinning the best content (versus lots of content) from others.
