SEO friendly redirection

Hi first off all i want to say that english is not my native language so maybe you guys will not understad what i mean but i will try.

so i have a cloacking script that scrapes content from digg, stumbleupon, etc. sites, and its hard to make google yahoo to index this kind a sites already,
but i also what to redirect from those expired domian sites i will have coacking script on to one main site, so the cloacked, scraped content is not seen for visitor(they should be redireted to main site) , but is indexad by google...

How to make this kind a redirect? Is there some htaccess trick??

If you are planning to cloak, I'd advise you to use one of the cloaking softwares available unless you are a good programmer yourself - even then, I'd suggest you go for a cloaking package.

The reason is that these cloaking script makers have a lot of experience in dealing with the search engines and constant tracking of IP addresses of the search bots. Without this, your site would be found out and be banned within weeks, if not days.

basicly i whant to use expired domain traffic, backlinks- together with cloacking script and redirect all that traffic to one site...
i have one good cloacking script but i dont know how to redirect like i said above..

A cloaking script would allow you to configure the redirects. which cloaking script are you using?

You could easily both create the sites you are talking about and cloak/redirect them with http://www.simplifiedsec.com. For the site creation portion, we allow you to scrape content from the search engines (it's all automated), scrape content from any rss feed source, and create custom content using articles, or your own written content which you can use variables to perform word replacements. In other words, a single article with enough replacements can give you enough content for hundreds of pages. You can control the keyword density and such quite easily this way.

For the redirection, well, that's simple. We use ip based cloaking on the server side, so the redirect can't be detected. Our bot ip list has over 20,000 ip's and is updated 3 times a day. Our next software release will include geoip based cloaking as well so you can send traffic to different places depending on their geo location.
