No, a better way would be to ping itch.io's official social media accounts with a link to your game page. An even better way would be to focus on making a good game with a good presentation and getting people to look at it. Features games are hand-picked, and staff finds them like anyone else would.

First you must have something that you think its good and people will want to play it. Then just hype it on much forum as you can and be active memeber in them. After release share it everywhere you can and people will come.
