The trap of constantly swapping your link
When you run several projects, the temptation is to change the bio link to match your latest video: the shop today, the podcast tomorrow. Except anyone landing on an older video then hits the wrong link, and you lose visitors without ever noticing. That is wasted traffic.
A link page settles this for good. Your bio link never moves again: it points to a page that lists all your projects. You stop chasing the right link and simply reorder the blocks on your page as your priorities change.
Organizing a multi-project page without cluttering it
The risk with several projects is the catch-all page where the eye gets lost. Give it structure: put the priority project at the top (whatever you are pushing right now), group the rest by theme, and give every block a clear action label (Listen to the podcast, Visit the shop, Book a call). A visitor should understand where to click in three seconds.
You can also set up proper deep links to each project so the right app or page opens directly, and shorten the URLs so they stay clean. If your projects speak to different audiences, a sharp label stops someone clicking in the wrong place.
Steering it and evolving without breaking anything
The advantage of one page is that you can evolve it without ever touching your bio. New project? Add a block. One on hold? Remove it. Big release? Move it straight to the top for the launch. Your bio link stays identical everywhere, on every video.
Then watch which projects pull the most clicks and adjust the order. If you really need to separate two very different worlds, you can create two distinct pages. But in the vast majority of cases, one tidy page does the job and keeps all your attention in one place.
