What to put on it
Your name, niche, and one sentence. A photo that looks like the videos. Platform stats you can defend: followers, average views or average concurrent viewers, and the country split if you have it. Two or three embeds or screenshots. A short menu of offers. An email that you check.
Date the stats. A kit from last year with a peak screenshot is how trust dies in the first reply. Update it when the numbers move, or when you change what you sell.
