[Help] Web 2.0 Buffer Sites Keywording question.. Please advice

Hello everyone!

I made web 2.0 18 buffer sites blogs for my money site.
I just wanna ask about how to use keywords safely. Well this is my first try ranking a website..

From those 18 buffer sites. I chose 5 keywords from my money site. So 1 keyword and 1 LSI per blog post..
And I have like 5 blogs targeting 1 keyword, the other 1 keyword has 4 blogs. and the last 3 keywords has 3 blogs each.. (all in all 18 blogs)..

Is 1 keyword and 1 LSI per post safe?
And 5 blogs targeting 1 keyword safe? how about the other keywords?

Thanks!

Don't forget publish post at least once monthly. x18.

Bump.. anyone? (short message)

Don't forget to add links from authority websites that are in your niche but not a direct competition to you, you don't want all 18 blogs to link only to your niche, its not natural and Google can penalize you.

Try using the website keyword revealer to identify low competition long tail keywords, I search, create a group then generate Seo optimised easy to read content based on those (obviously researched). Good luck.
