<b>Custom vs Lookalike audiences: telling TikTok who to clone</b>

Two audience tools sound similar but do opposite jobs. Let's separate them clearly.

— Custom Audience = a list of people who already know you (past buyers, site visitors, video viewers)
— Lookalike Audience = brand-new people who resemble that list, found by TikTok

Here's the deeper thinking. A Custom Audience is small and warm, great for reminding past visitors. A Lookalike takes that same warm list and says to TikTok: 'go find a million strangers who act like these.' That's how you grow beyond people who already found you.

The quiet rule: your Lookalike is only as good as the list it copies. Feed it your buyers, not just random visitors, and the clones come out far better.

Don't worry if this felt abstract, it clicks once you build one.

Try this: list one strong source you could upload (past buyers?). That becomes your best Lookalike seed. Nicely done.
