i was wondering if google might penalize me for having to domains for my site? i haven't done it yet but I'm considering doing it. i want to know if i might lose my positions on the search results. or would doing a permanent redirect be better?
"would doing a permanent redirect be better?" Use 301 redirect. "google might penalize me for having to domains for my site? " Google will penalize for duplicate content, but if you have 2 or more domains redirecting to 1 domain then its OK.
a permanent redirect will be google friendly, and imporve your main site's ranking. rather making aliase will cause definately to penalized one less important and young site. here is a little code for your help. somacon.com/p145.php
