A general 'PDF Resources' TikTok account can work well with a cohesive strategy. The key is to maintain consistency in tone and style while emphasizing the versatility and value of your PDFs. Showcasing how your guides solve various problems across niches can help attract a broad audience. However, niche-specific accounts often perform better because they target a focused audience with tailored content and messaging.
The internet marketing and health and fitness accounts you’ve already set up are great examples of this approach. A general account is worth exploring, but ensure it aligns with your goals and complements your niche-specific efforts to maintain a balanced strategy.
