Frequently Asked Questions
Why do fonts from the fancy text generator work on Instagram?
They are special Unicode characters, not real fonts, so they paste anywhere — Instagram, WhatsApp, TikTok bios and more.
How is engagement rate calculated?
The standard formula: (likes + comments) divided by followers, times 100. The tool also supports reach-based calculation.
Is the YouTube earnings calculator accurate?
It gives a realistic estimate range based on typical RPM values by niche and region, but actual earnings vary by channel.
