Now I'm creating my first global product and so what?

Hello everyone, for a while I've been following the Indie Hackers' newsletter and posts. I'm working as a digital marketer for about 8 years.

I'm also an indie marketer with side projects for some extra cash. Driving traffic with SEO and earn money from Adsense, also I build my own YouTube channel.

But now, for years I would like to build a live product. Now I'm organizing an Airtable sheet and collecting the best landing pages that CROs are high on.

I would like to hear some ideas for validating my idea. I will share my product on ProductHunt, Betalist and other communities; also here. I hope I will succeed in this project and share my results here.
