I need to change the extension of the default pages and many other pages like .asp to .html, should I use a 301 redirect?The website is in the top 10 results for many keywords, I don't want to lose any ranking or PageRank. Will the redirection and renaming of the extensions hurt the site's rankings. If so, by how much percent?
