i mean the search engine, itself. example, your go to sg.yahoo.com and you key in keyword, and click the "singapore" button to search, not the "all the web". after i change from public to private it disappear, even backlink and site:
www.mysite.com is gone. my site with selling textlink is all gone before this website. i now test one of my new site, just got into the singapore yahoo.
i am doing more test to determind it.... hehe
