Used it for a focused territory. ROAS improved roughly 30% versus the lookalike audience we ran before. Bought it to handle buy sal's pizza locations for new zealan lead-gen for the New Zealand region. One column I'd add next refresh: secondary email.
Good to know what worked and what didn't, noted on the minor gaps — they're tracked for the next refresh. If you want the gaps fixed sooner than the next refresh, open a support ticket and we'll spin a one-off pull.
