Wrong domain name in Yahoo

[webpundit]

We have registered a number of domain in our name due to trademark issues. We have 2 major domains, say www.Primary.com and www.Secondary.com. Both domains have the exact same content, but we're not using redirects.

We use SiteMatch to submit URLs into Yahoo because we have a very large site (over 400K pages.)

We submitted only 1000 pages with the Primary.com domain name through Site Match. So, when I do a search on Yahoo for www.Primary.com, I get only 1000 results. However, when I do a search for www.Secondary.com, I'm getting over 450,000 results! How can this be? We never submitted this site and we have not been marketing it either.

What do I do? And why is this happening?

Somehow the Yahoo spider has picked up the second site. All you need is one link to secondary domain from any site and it will be discoverd. Why complian, if everything is spiderd. But if you wnat traffic to go to main domain, then you can put a 301 Redirect on the secondary site. That will tell Yahoo to index second site instead.

On the first site, I would recommend cancelling your Sitematch, since you are already listed for free.

But why would only a couple of pages from our main domain be indexed by Yahoo and so many pages be indexed from our secondary domain? Will a 301 redirect mean that more pages will be included from our main domain?

I am planning on expanding our PFI for the main domain through Trusted Feed. But all these pages are already in there for free...only, with the secondary domain with no tracking. TFG does not seem like a good solution for pages we already have in there (albeit with the wrong domain)!

Solutions, anyone?
