Customize Search results in Enterprise search 2010

I work with SharePoint 2010 and I'm开发者_运维知识库 very new to the same. I've been assigned the task of customizing the search center results to reflect entries of one particular subsite in our intranet at the top at all times. Any suggestions on how to go about getting this done? I will be much obliged.

The ordinary way to do that is to set the subsite up as an authoritative source:

1. Go to Central Administration
2. Click Manage service applications (below Application Management)
3. Click your Search Service Application
4. Click Authoritative Pages (below Queries adn Results)
5. Add the URL of your important site in Most authoritative pages
