what is the Mechanical turk?

you are absolutelty right Thomas!

If you redirect it to another site with 301 the domain will disappear from google. If you like to keep it then use a 302 redirect. I hope that this helps.

I read the post of Rand. Is totally out of my point of view. This kind of subdoamins I know that they don't pass anything to your site. http://www.seomoz.org/article/search-ranking-factors#predictions. Read this post and you see what I mean. I mean to build subdomains of your site which include the keywords in and my main domain to be with your brand. Like this you avoid the devaluated old trick from the exact match domain, you build your brand and you have also the keyword inside the domain and not in a subdirectories as a subdomain is much powerful like a subdirectory. Me like this I am working and is going pretty well. Also the content on the subdomain must be related to the main site and to be connected between them. I think Egol can tell us if me or you is correct. Maybe we are both wrong but me I don't think so .... Anyway cheers and be happy. From where are you? Me I am from a small island called Cyprus, in Mediterranean sea, down from turkey.

Here the marketer is wrong. Dont have any effect if the domains dont have authority.

Anyway I think you did wrong that you purchased them , you shouldnt, this what you should do was to create subdomains including the desired keyword like

http://keyword.yourdomain.com as this method will give a faster ranking for the subdomain if your main site have an authority. Now you will have to build for all domains the authority. I think you should throw them and build the subdomains. Also I have to agree with the marketer which said that should look like the main site.

yoursite.com/keyword-phrase this method Keith also got devaluated from this what I know and what I saw in action on my own domains.

Another minus of your tactic is the extra money for the domain names and hosting etc...

My method is absolutely free if your hosting provider allows you to host multiple or unlimited subdomains. For example hostgator allows me to have unlimited subdomains at no charge.

They have zero benefits if they dont have backlinks from niche directories or whatever related to the keyword. I have to agree with you.

Hi there   Ron

First of all the exact match domains get devaluated from Google. You mean subdomain by the term internal pages? What you mean by the term "point domain names at internal pages" ? To redirect them to internal pages? Or to create internal pages from the keywords? Example:

http://keyword.yourdomain.com

or

http://yourdomain.com/keyword

ot to redirect the exact match domain to this one ?

http://yourdomain.com/keyword

please tell me some more details so I can help you...If I can !
