What should I do with these 2 domains?

I have 2 domain names that I bought awhile ago for little projects that didn't go in the direction I had hoped. My goal for these 2 domains is turn them into $5 a day money getters so I can earn small extra cash and also learn about SEO.. So my question to all you domain gurus is. Is it possible to rank a site in a niche even if the domain has no keywords for the niche? Should I even try? Thank you

Keywords in domain is not a necessity to have success . So go ahead and build your sites confidently. Focus on content.

Keywords in the domain name can help but is not need it to rank.

Excellent. Thank you to both of you
