Great question, and it depends on how you want to approach scaling and discovery.
If your niche audience lives mostly on Twitter, it makes sense to start there, especially for early traction and community building. Twitter is great for direct engagement, trend-jacking, and organic conversions in tight-knit niches.
That said, don’t rule out Meta Ads completely — here’s why:
Retargeting: Even if your top-of-funnel is Twitter, Meta is fantastic for retargeting site visitors and abandoned carts.
Lookalike Audiences: Once you’ve got some buyer data, you can build lookalikes on Meta to scale beyond Twitter’s reach.
Visual creatives: If your product is visual (fashion, gadgets, art), Meta's ad formats (Reels, Stories) might perform better than Twitter’s limited visuals.
Smart Strategy:
Start with Twitter organic + ads to test messaging and build proof.
Add Meta retargeting pixel early (even before you run ads).
Once sales come in, test Meta cold ads using proven Twitter hooks and creatives.
