What will you do with the subdomains, keep it or remove it?

[teconsite.com]

A client of us has this webpage

http://www.losestores.com/

not very good in design, but it has good products.
He is having a problem with SEO, he is in page 2 for "estores" keyword. His domain authority is 27 and is upper than other domains that are ranking in page one.

The question is the following:

Since the webpage began to work the programmer that created it, did the following: a subdomain per section

http://estores.losestores.com/

http://cortinas.losestores.com/

http://venecianas.losestores.com/

and so on.

This page is not very big one.

Will you remove the subdomains and do de following?

www.losestores.com/estores

www.losestores.com/cortinas

What will be best?

Thanks

Victoria

Hi Victoria

By coincidence I was looking at a seomoz blog about this earlier. Its dated 2009, but I think its still valid and explains this issue pretty well.

in summary, it's better to go for sub folders rather than sub domains, ie www.losestores.com/cortinas

If the content in the subdomains is directly related to the main domain's content, then yes the folder approach would be best. You would consolidate all your links and domain authority into one strong domain. With the subdomain approach your DA is divided.

If you proceed with this change, be sure to properly 301 redirect the URLs and update all links within your site along with any other links you have control over in other locations.
