In which rartio We have to work on website home page & inner pages -resolve my query ?

Hey Warriors,Can you clear one more question revolving in mind that if we are working the website i will clear you as i am working one of the web designing website then from long time keywords are not ranking in SERPS as i am working in the keyword web design company, it was standing on 18 number from long time .

Now the question is that at that time i was working on only one keyword web design company linking it with home page . Now i have started from last 1 week working on different keywords assigned to different inner pages and home page . Now i have started working inner keywords with their urls and along with that working on important keywords of home page with it url as i am working on all keywords now not working on only one as it consider as spam as per my knowledge.

So as i have discussed with you Is it the right way to do the seo for my or any website logically, and please tell me one thing in which proportion or ratio we have to work on home page and inner pages . as our 1st priority is always to make globally presence of home page in the search engines .
