I have a Yahoo store and own three different URLs (which includes the default "mystore.stores.yahoo.net" domain). So basically it's like this:
I want all of these URLs to point to my one Yahoo store.
A Yahoo help page says this..
Each Yahoo! Store currently has multiple URLs to get to identical pages (for example store.yahoo.com/accountname, shop.store.yahoo.com/accountname, stores.yahoo.com/accountname). If you search for your store using a search engine, you may see these different URLs appearing in the result pages. This may be a problem because the relevancy rankings are spread out among those URLs, whereas you may want to optimize the relevancy rankings to just one URL.
A feature was added to the Domain Name Management page that allows you to select a domain or hostname to which to permanently* redirect (301) all Yahoo! generated URLs. By default, all Yahoo! Store accounts will be set to "none" meaning no URLs will be redirected. By default, all Merchant Solutions stores will be set to redirect to the store.yourdomain.com/page.html where your domain represents the domain you selected at signup or upgrade to Yahoo! Merchant Solutions. You can choose to redirect all Yahoo!-generated URLs to any hostname or domain name listed on the Domain Management page or even to not redirect any URLs.
For some reason or another, just recently, a lot of my targeted search terms are showing up with the "mystore.stores.yahoo.net" address instead of my main personalized domain name that was showing up previously. (No loss in keyword position, mind you.) However, just last week my page rank dropped from a 4 to a 2. What is going on? How do I properly do a 301 redirect within a Yahoo store? The Yahoo folks are very vague and seemingly knowledgeable about their own product. I need help, fast!
