Does "URL masking" effect SEO?
For example: masking "www.domain.com/p/page.html"
to subdomain.domain.com
*Means everyone who visits "subdomain.domain.com"
, see "www.domain.com/p/page.html"
page, but the top address bar shows "subdomain.domain.com"
Edit: I have a blogger site, and the URL-redirect-masked/Hidden Frame Mask records are created on my DNS. Currently, "subdomain.domain.com"
is indexed, and I have removed the original page "www.domain.com/p/page.html"
from google index to avoid duplicate.
The masking is done with frameset:
<frame src="www.domain.com/p/page.html" name=mainwindow frameborder=no framespacing=0 marginheight=0 marginwidth=0></frame>
