I have an idea. To make a new "link in bio" site. It can be differentiated, of course, but should I do it?
The keyword "link in bio" is searched between 10K and 100K per month. Still, would making a new alternative bring customers?
I would think most of these searches are users, not content creators. You should converse with content creators, no one probably would have thought linktree would be a thing, I've seen it early and didn't understand, it's very niche specific to content creators on specific platforms, I still think it's weird it's needed. Maybe you can find the same concept of a specific custom one page for some other niche. Generally it's better to start with a niche more than a solution, it's easy to get sucked into making a better mouse trap that nobody is looking for. (But honestly mouse traps aren't properly solved if you ask me)
