Direct traffic improve SERP af ? kw 34 from 9

Hello,

I own a really new and fresh website. I'm rank on most of the kw I want. I have a nice direct traffic source with qualified traffic (they spent around 4/5min on my website). Actually my website have 2/300 visits per day with seo, and I can bring with my traffic source 3/4000 unique qualified visitor to my website (they will post comments etc, that's real and good quality traffic).

I've try a day to use my direct traffic source and bring all of my traffic to my new website. I've see something amazing on my serpbook, all of my main kw have up a lot the day I've use my direct traffic source.

I was rank 34 on my main kw the 28 march, then the 29 march I use my direct traffic source and bring 3000 unique qualified visitors to my website and I'm now rank 9 and it doesnt really decrease:



Same for all of my kw..

Can you explain me why ? Because I've search a lot on the internet but NOBODY say that direct qualified traffic can increase kw rank

You think it's the direct traffic who have make my serp increase or it's the content all of the users have post on my website ?

I dont have big big knowledge in SEO.. thanks, and sorry for my bad english

Without more details it is difficult to say for sure. You might be able to find some information using Google Webmaster Tool's, but since your site appears to be pretty new here is my best guess for your query:

No the direct traffic is not the precise determinant of your rank. It plays a role, but G's capacity to process that information to the extent of making a major ranking impact in that period of time is negligible. While having a low bounce rate, and good on-site interaction will help you long-term with rankings it is FAR more likely at this time that your keywords are non-competitive and/or your pure content is of high enough quality to warrant that jump.

All this assumes you did little to no off-site backlinking. For low competition words a well silo-ed website can very easily rank page 1 for keywords with content alone, so this is the most likely scenario, but it is definitely beneficial to keep those other key metrics high particularly if you are using Google Analytics for stats and traffic tracking.

It really just seems that moving from 34 -> 9 would be very unlikely to result solely from on-site metrics measures. More likely the content is ranking.
