How to Best Manage Multiple Domains?

[thealika]

Hi,
I am new here and this is my first question.
(so please excuse if my etiquette slightly off)

I have just taken over the SEO work for a website in South Africa (.co.za) it is for an Attorney of immigration law, and naturally I would love to make it into a star on google.

I have about 15 extra keyword domains at my disposal, 5 of them are parked and the rest are not doing anything at the moment. so my question is: what should I do with them to get the best SEO results for their keyword names?

I was thinking to make a WordPress Multi Site, un-park the domains and create a separate site for each domain. Create a visually similar front page, but all the links head back over to the main site. Then work on optimising the SEO for each domain. (lengthy work but it's not too hard to rank in google.co.za)

what do you think?

I also heard that parking domains is a bad Idea, because google sees it as duplicate content; is that so?

website:
www.migrationlawyers.co.za

Parked domains:
MigrationLawyers.co.za
MigrationLawyer.co.za
MigrationLawyers.de
ImmigrationLaw.co.za
EmigrationLaw.co.za

Keyword domains: Migration-Attorney.com
Migration-Lawyers.com
MigrationCounsel.co.za
ApplyForPermanentResidencesSouthAfrica.com
AvoidDeportationSouthAfrica.co.za
AvoidDeportationSouthAfrica.com
RetirementVisaSouthAfrica.com
SouthAfricanCitizenship.co.za
SouthAfricanPermits.co.za
StudyPermitSouthAfrica.co.za

Thanks a lot,
Nikita

To be honest I would focus my efforts into making one or two really good websites rather than making 15 different websites.

Using exact match domains on a larger scale is a lot different in today's market in comparison to say 2 years ago where you could make a 5 pages site and get the EMD ranking.

If you do go with a 15 site strategy, you need to make 15 x sites, 15 x content pieces to make sure its unique, 15x splitting up hosting  I would not even use any tracking that can link up the sites imo.

Fair enough, and good point!

I wasn't planing to concentrate too much on all the 15 sites. 
I think maybe I should heed to your suggestion and make 2-3 sites.

So what should I do with the other domains. (my customer told me he has quite a few more, and is waiting for the login details to come through and he will hand them over to me) what is the best way to utilise them?

thank you very much.

James is correct, is a lot of effort that you could be putting into your primary site.

If some o ne them have good exact match keywords in the domain, them it may be worth the time.

I have a few sites, selling the same product, but I did this because I already have my primary site performing at its optimum, so them putting time into a second site to crowd the results makes sense, but I would be trying to get the first site to the top first.

What do you think is a good "TOP" ? do you think there is a good time to say, hmm that is enough, i can start building the other sites?

Thanks

When your ranking 1, 2 or 3 for your main keywords, depending on how competitive your keywords are. when you don't think your efforts will get you much further. Example don't waste your time trying to beat wikipedia
