One of my website was developed with .net and url extension were .aspx. Recently i converted the site to php where urls extension are .php and all the urls were rewrited from .aspx to php.
I have few My doubts and issues hope it can be solved here
1) All my internal pages PR were dropped to 0 is that due to url change? if so why rewrite has not helped or still i have issues with my rewrite.
2) I developed lots of back links for my old urls (.aspx) is that i need to change all the existing back links to new urls (.php)
3) Still i am continuing my link building and links were secured for new urls. Is back links of old urls (aspx) and new urls(php) with conflict or rewrite will care of this?
4) couple of urls lost their rankings in google but not all. Is that due to url change
Advance thanks for your valuable feed backs
