Framed forwarding of domain names bad for seo?

should I avoid frame forwarding for seo?

[mancunian]

I am trying to save money and have many domain names for completely separate websites but only one webspace to save money. (note there are no page name conflicts so it is possible)
My current hosting company who I need to stop using allow the setting up of alias domian name s on a single web space which is great.

However my new hosting company only allow aliases to be set up on very expensive accounts.

They told me that I can still buy new domain names and simply have "framed fowarding" to the web space which is similar but bot the same as an alias.

I am concerned that theis "framed forwarding" will have a negative effect on seo just as normal frames do on web pages. However I do not really undrestand what framed forwarding is!

Can anybody tell me the best way to host many different client seo pages on one web space (no home pages involved so no conflicts) and is "framed forwarding" a potential problem to avoid?

Thank you

If your host permits server side scripting (PHP, ASP, CFML), just write a bit of code that redirects the user to a page based on the domain name.

So (pseudocode):
get CGI.http_host
CASE CGI.http_host IS 'site.com'
GOTO /site1/index.htm
ELSE CGI.http_host ID 'site2.com'
GOTO /site/index.htm
ENDCASE

I recently ran into a major problem with frame forwarding - on Yahoo. The principal domain simply vanished and all the content was attributed to the framing domain with URLs that were a hybrid of the two.

It is now 3 months since we purchased the raming domain and took it offline. However, Yahoo has not brought back the original, which was in their database for almost 10 years and is in their directory.

A helpful Yahoo employee tried to get the issue fixed, but so far, no go. As I was told, "It shouldn't happen." -- ah, yes, but it does!
