No evolution in my ranking

Hello All,
I have already post a message here some weeks ago and i was asking how to rank my website, i worked a little on my SEO and keywords, and now i start to see my keywords in the SERPs,

I have optimised the content of every article for a special keyword, and verify the keyword density, etc. Now i dont know what can i do to have a better ranking. Except of optimizing my keywords in the content and working on internal working, what can i do more ? Help plz and plz dont ignore my message thank youuuuuuuuuu

keyword density is usually a trap... measure how many matches your page one competitors have and be competitive with that. See how they get their high match counts without getting penalties. If your website is very new it can take months to get credit for your backlinks. You just have to keep moving forward knowing eventually it all comes into play. Don't forget email, PPC, and social. If you ignore the other channels you are ignoring 85% of the opportunity.
