Will a mirror page hurt my site?

mirroring on a keyword-rich domain name

[tigerflag]

I have a niche business selling blue widgets. I didn't know anything about SEO when I started, so my domain name has nothing to do with my product. Call it www.abstract-name.com. My site is high-quality, with unusual products, lots of original content and valid code. I'm very proud of it.

My main keywords have a lot of competition. Many of the top listings in the SERPs are not as relevant to the keywords as my site is, but in spite of a lot of SEO I'm having trouble being seen. I just bought two domains, called www.bigbluewidgets.com and www.bluewidgetsonline.com . They are on a different IP address than my main site.

I would like to make a mirror of my home page and put it on the two new domains, using title and description metatags specific to the keywords in their URLs. If I did that and had all the links to deeper pages point to the pages on my original site, would that be considered unethical?

In other words, I would not be using a redirect, instead I would be using hyperlinks back to my original site.

If people doing searches for those keywords clicked on my site, they would be taken to a very relevant result. So in that sense it isn't dishonest. But is it considered black hat, and will I be penalized for it?

Thanks

This doesn't sound like the best approach - if you tell us what you are trying to achieve by 'I would like to make a mirror page of my home page' we might be able to advise you better. :)

The homepage on my existing site shows five types of blue widgets, with each category going to its own page where people can buy the products. There are also links to information sections with articles I've written about blue widgets, links to contact info, shipping and return policies, etc.

I don't want to duplicate the entire site. I just want the new domains to bring up a page with the same good content as the original site, and when people click to go to a deeper page, they'll go to the deeper page on the original site and shop from there.

Would I be penalized for this? Would the penalty come from being a duplicate page? If so, perhaps I could change it sufficiently. Or would the penalty come from having the page link to pages in my site? I don't want to create thousands of pages like this, just two that have relevant keywords in the URL.

It sounds awfully like a 'landing page' and not the good type.
Its certainly not a technique I would use.
If you have a cluster of pages devoted to Blue Widgets of Type A, you are probably better to farm them all off to their one site together?
But I'm not sure I would even do that - having everything on one site reduces your offsite SEO overheads, as well as your general update time.
I realise you can see this making sense in your head, but from practical experience, I can't see the point of adding a new domain for this :(

Anyone else?>

Thank you for your help; I really appreciate it. I did a lot of reading on landing pages, duplicate content penalties, etc.

I ended up making two pages, each with different titles, descriptions, anchor text for the links, and modified the copy in the body. They are optimized for the keyword in their URL's. I ran them through a duplicate content checker. While they have the same stylesheet and look similar visually, they're only 41-44% similar to my existing homepage, and 56% similar to each other. So I can rest easy that they aren't duplicate pages.
