Does Google still see masked domains as duplicate content?

[TracyWeb]

Older reads state the domain forwarding or masking will create duplicate content but Google has evolved quite a bit and I'm wondering if that is still the case?

Not suggesting that a 301 is not the proper way to redirect something but my question is: Does Google still see masked domains as duplicate content?

Is there any viable use for domain masking other than for affiliates?

To my knowledge, yes.

They have certainly evolved, but in my opinion their evolution would point only to the fact that they will see through masking tricks even better than they once did.

I ran an experiment with an affiliate link in 2008, and because the domain I purchased was the exact match of a product (the owner was trying to brand his name with his domain instead of the product which people actually searched for), and my masked domain was ranked #1 for weeks!

Shortly thereafter though, Google realized it was duplicate content, and while the experiment made over $1,000 in that time, the moral of the story is that they did catch on, and the rightful owner of the site reclaimed the #1 spot (and my masked domain got the boot just like it should have).

If they were able to detect this 3 years ago in my little experiment, I would bet they could detect it now much faster, so in my opinion it would be best to avoid these tactics altogether.
