new domain for each sub-niche? | warrior forum - the #1 ... - g skin care products

Hey warrior, I really need your advice.
My health.
Can be used to promote related domain names of different subdomainsniches (e. g.
Weight loss, skin care, etc. ).
Do you think I should use the same domain for each child User
By creating new market segments
Directory (not subdirectory)
Domain) or purchase a new domain with keywords for each subdomain nameniche?
In terms of SEO, are there any obvious pros and cons of these two methods?
Thank you very much for any comments. Thanks!
