How long with no conversions do you typically continue ad spend?
But, no one should be advertising on Twitter for any reason anymore. It’s not brand safe and it’s always been absolutely trash; but, now it’s even worse.
Shift your budget to any other meaningful platform within the channel; you’ll be glad you did.
I was in Hong Kong for two weeks late last year and every time I opened Twitter there I saw a promoted post for a voachinese.com article (something something China bad). It’s always VOA Chinese even though my language is clearly English, and my account is completely passive, never tweeted anything, liked anything or followed anyone, most of my visits are HN referrals about something tech related. It was quite surreal, like they bought the entire ad space of the region or something.
