Using sub-domains for marketing - any good?

I have some old 4 and 5 letter com domains. Just wondering if I should use those for keyword rich sub-domains on those short domains. Like TrainYourPuppyIn30Days.abcd(.)com (Just made that up - I wish I did own the abcd(.) domain.

Of course, I could do it, but does it help your marketing?

I do own the 0l23(.) com domain - the first two characters are lower case letters "O" and "L". (Right now it is just a blank page.) Just playing on godaddy one day. Not very good for someone to type in, but it looks nice. How about LoseWeightNowAsEasyAs.Ol23(.)com

My initial research says that Google ad words can use sub-domains in your ad as the destination url. Just don't how good it would be for SEO.

I would also save the cost of each domain name. (godaddy has made a chunk of change from me over the years)

I could even have a lookup page on the short domain name page to link to each of the subdomains.

Has anyone used this technique with any degree of success?

 

yes dear, sub doamin are really helpful to get targeted audience, u need to promote at right place.

 

Subdomains definitely help in seo marketing.
As long as the subdomain offers substantially distinct content, Google and the other search engines index and rank subdomains the same way they would any other website.

 

Something should be keep in mind. There are lots of sub domains you can find in the Google search engine ranking. So, you cannot through it out of marketing. I haven't yet apply the technique you mentioned here, but it seems nice to me! And definitely the domain automatically be famous over night.

 

I use sub domains as well but in SEO sub domains are treated as seperate domain names in terms of rankings, so please keep that in mind.

 

Ive had much higher rankings using EMD than a subdomain using the same keyword in the domain. Ever thought of registering a new domain name as your brand and create an authority site? Thin sites tend to be knocked out to the SERPS eventually...

 

EMD -> exact match domain. I agree - much better. For a lot of them the problem is domain cost and finding a keyword rich domain name. The sub-domain can be (almost) anything.

I was thinking of a site with several hundred sub-domains using a wild card technique with a data base for the info on each sub-domain set of pages. Would only take a few templates with PHP replacement on the pages. Then some code to link the sub-domain name to the database entry which in turn would populate the template. Change the templates and change all the pages.

Could even make the page extensions htm or html and tell .htaccess to process them as php pages. I don't think Google cares about the extension, but to the casual user it would look like a whole bunch of html pages.

Then do a custom page (password protected) to facilitate maintaining the data base. Simple cut and paste to a form to create a new sub-domain with associated information. Could have multiple similar sub-domain names going to the same page.

Maybe something with like a whole bunch of ShareASale or ClickBank offers.

I have the basic design worked out. Should start coding in the next several days.

I was just wondering if anyone had any success using this technique.
