What should I do differently with my SaaS websites?

Hi, I continue to launch SaaS products at a young age, although keep failing. I have like a hundred signups on https://obeatow.com, but keeping changing things hoping to get sales. Before I build a SaaS, I do this: Come up with something thats missing from existing solutions. I find a name for my SaaS by spending forever googling a word each time with a new variation of letters. Its a pain, but how else is my SEO worth it like literally. Then I check the domain status, and buy it since I want to get my Idea out there. Make landing page with Tailwind and build it as waiting lists suck.
