Best Site Structure/Contenr for SEO?

For site structure I was wondering if I should:

Post an article and use it as a homepage (then internally link my content within to pass link Juice)

OR

Should list all my money making articles within featured post blocks (that way it looks like a nice landing page for users to navigate through, also passing link Juice specifically to just those articles) ?

For content, I was thinking of writing several articles to rank for every keyword within my niche's keyword.

I've been reading that longer content does better in ranking in google. Also I've read that less articles on your website improves SEO.

Should I write a long article and include those other keywords as H2 sections in my article?

OR

Write articles for each of the keywords then internally link it to my main keyword?

You definitely should be including the fringe keywords you're targeting as H2s and H3s - it'll help you rank for them better.

Post an article and use that on home page with a snapshot - brief info and link that article with internal pages or featured blog posts.

Write long articles - 800-1200 words in a natural manner covering your SEO Keywords and link them to relevant internal pages.

Hope that helps.

Good luck.
