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.comEdit: 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>
Does URL masking effect SEO?

The masking is done with framesetUsing a frame, often called framed forwarding for masking the real URL is generally bad for SEO and delivers a bad user experience.The URL inside the frame is not hidden from search engines (or users). There are essentially two separate pages/URLs and both can be indexed. The only page with content is the inner/framed page, so this will likely be the page that will be returned in search results (if it is indexed).I have removed the original page www.domain.com/p/page.html from google index to avoid duplicate.You can't remove the inner/framed page from the index without removing the actual content from the index. Without the content being indexed then you are obviously not going to rank for anything on that page. The outer frameset is simply a container, by itself it has no content.There is no duplicate. They are two different URLs. One simply contains the other in a frame.When the user navigates your site the URL in the address bar does not change (as you suggest) and they are unable to bookmark individual pages. This can be confusing and frustrating for users.<frame src=www.domain.com/p/page.htmlIncidentally, without the scheme (eg. http://) on the URL this is likely to break in most browsers (historically this would have only worked in IE).
