Any value to redundant sites?

[AuctionHugh]

If I have www.mainsite.com with a good PR and search placement, is it possible to HARM my placement with the following?

1. register www.good-keywords-1.info and www.good-seo-words-2.info.
2. copy my entire exact www.mainsite.com to the above sites
3. submit www.good-keywords-1.info and www.good-seo-words-2.info for listing on the major search engines.

This would be fast and cheap - but might it harm www.mainsite.com placement or have any backlash that anyone knows of?

Yes, yes, yes Google and the other SEs hate duplicate content and consider it spam. Develop original content for other domains or better yet, concentrate on the site you have and promote that.

The two new sites will jump up and show good in the search engines for about two weeks and then they will totally disappear. Never to be heard from again.

A better way would be to target the keyword and have every page on the site targeting those keywords, with unique content.

Or

Turn them into blogs and do what I did here.

Do not do this as it could harm your current website placements.

Do not do this as it could harm your current website placements.

I've never seen it harm the main site.

[incrediblehelp]

Sure it potentially could not harm them, but that is not say that it wont some time in the future. The fact is if let the search engines pick which website(s) to filter it is a never a good idea.

If you create completely new websites, new verbage, new content....it might help. But it would be better to put all that energy into the one

My thumb rule for new sites will be creating unique related content to complement the main site. That way, you will have the advantage of boosting the ranking of the main site as well as getting new traffic from them.

I do not see the point of having 2 new sites having the same content as the original unless you are doing a 301 redirect with the site names relating to the main site.

You will almost certainly be penalised for Duplicate content especially by Google. Using no index or robots.txt to stop search engines form indexing one of the websites will avoid this penalty. However the purpose is lost entirely assuming that wanted to do this in the first place so you can target multiple keywords for the different sites.
The best way will be to use t least slight variations of the content and titles so they are not treated as duplicate content by search engines.

Don't forget that Google is a domain registrar, meaning they have unfettered access to the REAL whois data (including hidden iownership). If all 3 domains are registered to you, then what do you think?

Honestly this is a VERY bad idea, take the thought, wrap in some nice 2ply toilet tissue, and flush it away forever, never to be thought again :)
