My client is a CPA firm that had a website built with a CPA site builder company. They no longer want that site, but I have earned them good rank with many of their local keywords. We have designed a new site and sent them an htaccess file with correct redirects, but they are not responding and won't implement the redirects.
Is there any way to save the link authority of the old urls on my new site? I have domain access (GoDaddy) but no cpanel access for the old site to add the htaccess file. Right now, I have forwarded the (OLD).net site to the (NEW) .com site, but I think I will lose all link authority of those previous .net links. Any suggestions?
