Why result came twice time in SERP?

Mostly I found twice time ranking result in Google search engine ranking result pages especially by website design keywords(jordancreekdesign.com). Why so on? And I want to know this is a positive effect according to search engine point of view.

Do you mean that in a search result, you saw one website coming twice ?

If yes, then I guess its positive. In yahoo, when I search for few keywords, one of my sites page come on top, and on the 4th place, there is another page from my site

 

if it is a search results, then google will correct it sooner or later

 

yes it happens , and there are no. of factors responsible for this

 

If you see the same ranked url in two different pages then it's updating and soon the older one will be removed but if you are seeing two different urls from the same website and they are seperate from each other then it's ranking because each url got it's own backlinks, and if they are under each other then it should be the main url and the url which is linked from the main url.
hope you can understand and i was helpful.

 

maybe some problem in it..
