Question. You stated the PR value is based on the meta info and text. All that will change as basically I am chaning up my keywords and text so yes it will change
Also the only part of the URLS that will be the same (or at least will like to keep the same) will be the blog post. My MAIN PAGES liek about us, contact etc, those pages will change the URL as it will focus on new keywords. So with that in mind will I still lose my PR4 status with the new info im promoting?
