Yes dp dropped by one position for the keyword “dp” in google.com or google.in ….

I am from India. I am such a lazy guy that i never tried to write whole url in browser to open digital point. I just type this “dp” keyword in google.in or google.com to open forums.digitalpoint.com. My expected website forums.digitalpoint.com always comes in first position in google for the keyword dp.
I was shocked that dp drops by one position for the keyword “dp”.
This is the first time i am seeing dp in 2nd position.

My question is Why dp dropped by 1 position??
Few of my thoughts are:
1) From this i can say google algorithm always gives first preference to combined keywords in domain name.

2)Does google gives position for fresh pages? That is in top 10 pages. “This is G o o g l e’s cache of http://www.dpreview.com/ as retrieved on 8 Jun 2008 14:41:10 GMT.” This information is taken from google cache. Do you agree that google gives position for fresh pages (fresh content)?? If yes please reply me.

3) I have observed google is giving 1st preference to those websites which is having more number of similar pages. Total number of similar pages for this website (http://www.dpreview.com/) is 29. Which is highest in top 10 pages. I am comparing only with those websites who are having keyword “dp” in domain name for top 10 pages.

4)Now open page source for www.dpreview.com (ctrl+u) . I have observerd that google is giving good priority for keyword frequency. the word “dp” is repeated total 116 times which is highest when compared to top 10 sites in google 1st page for the keyword “dp”.

5)Traffic does not play any role for positioning. Why because when compared to digitalpoint traffic dpreview traffic is nothing. do you agree??

These are the main reasons i have found why dp drops by one position in google search for the keyword “dp”. From this i can conclude that we can bring any page in top position by propor On- page optimization.
