Hi, I am doing link building for one of my credit card related site. But the thing is most of anchor texts which I have given from other websites are pointing out my website without www like http://example.com. Now I am planning to redirect this one to http://www.example.com. So If i do this will it affect my current ranking positions ?
That does not fix the problem completely. You need to do a 301 redirect here is the info http://redfoxseo.com/2009/10/301-redirecting-your-web-sites-main-page/
Yes it will. Also it will be good to do a similar 301 redirects from http://example.com.index.php & http://www.example.com.index.php to http://www.example.com Hope this helps.
