Viral score

Based on absolute engagement — the platform doesn’t expose follower counts here, so large accounts score higher.

From likes, comments.

The mechanics

Hook: Announcement
Structure: Hook
Style: Conversational paragraphs at a steady pace.
Tone: corporate
Written for: Marketers and content teams

I'm back from a week at my mom's house and now I'm getting ads for her toothpaste brand, the brand I've been putting in my mouth for a week. We never talked about this brand or googled it or anything like that. As a privacy tech worker, let me explain why this is happening. 🧵

Oh my god. When Linda Yaccarino said that Visa was a “returning advertiser” she meant the company spent $10 on Twitter ads in the last 12 weeks. Not ten million. Not ten thousand. Ten dollars.

Today we're announcing Live Studio, a brand new livestreaming command center on X X is where everything is happening now. So we're launching the best tools for pro streamers to go live, connect with their followers & manage their streams Check it out on 𝕏.com in Creator Studio

MY FIRST X VIDEO MADE OVER $250,000! 😲 But it’s a bit of a facade. Advertisers saw the attention it was getting and bought ads on my video (I think) and thus my revenue per view is prob higher than what you’d experience

Hi! I'm one of the prompt writers that worked on this ad. It's a lot harder than people think! Prompts that my team used include: -make it funny -make it epic AND funny -funnier!!! Please be nice to my team as many of them will be laid off/replaced by AI
