I have a primary branded domain, but have acquired 2 generic domains that are basically the biggest keywords for my product. The experience I want is that if a visitor comes through www.domainA.com, www.DomainB.com, etc, for that to be the domain that person will see (as opposed to a redirect), At least thats what I think I want, I'm still learning alot.
The reason I'm looking for this solution is that I want to use the generic domains in AdWords campaigns, but Google doesnt seem to let you advertise domains with redirects.
What is the reason for using keyword rich domains for ad landing pages. Wouldn't it be better to use the branded domain, and push the brand and trust in you?
Shopify does have the option to switch off redirects to a primary domain. This may give you what you want.
A word of warning. The same content on duplicate domains can make it harder to get rankings. You will have three copies of every page competing with each other, instead of one authoritative copy that gains all the ranking signals.
The reason I want to use them is because I was able to acquire them very inexpensively, and many of my competitors are using some variation of the product in their branded domains - but now I own by far and away the best two URLs for this product.
I'm thinking of eventually changing the brand to BE the term, but it would just be a ton of work right now editing the brand through the entire site and email setup.
So if I do what was suggested earlier in the thread - use 301 masked redirects through my registrar, Google will recognize each page for each URL?
With registrar forwarding you have to work out exactly what they are doing.
I think masked normally means they use a frame to make it look like the original domain, but the destination domain is inside the frame. Typically bad for many reasons.
There is no such thing as a 301 masked redirects. 301 are a specific header respones which causes the address to change. When registrars talk about an unmasked forwarding they are typically talking about a 301 or 302 redirect.
Shopify lets you add multiple domaions to their system and you can select not to redirect. I think this lets you create duplicates of your store, but you should check with them about it.
