[Help please] Quick question about 5 similar keyword groups

Hello folks,
In my niche I have 4 keywords of interest that have one word separating them. The site will be about both.

One is like:

"weight loss capsule"

and the other

"Weight Loss Pills"
"product for losing weight"
and other 2 keywords ...

They both get a bit of traffic but little competition, though my first keywords gets the most traffic. but for others keywords there is not much competition

Should I make one page of 1500 words for each keyword and write articles for each page, or should I try to include one page of like 8000 words for both keywords and have all the articles point back to one page? and after send some backlinks with differents anchor text.


Thanks and sorry for my english !

My suggestion would be to change from "weight loss capsule" which seems very generic to something of more interest to those who want to lose weight, which is losing weight quickly! For example - "quick weight loss capsule" , and you could do the same with "pills", etc. Then your articles could be about how people can lose weight quickly, which as I said before is of great interest to many.
