How to Submit XML Site Map with more than 300 Subdomains?

[vaibhav45]

Hi,
I am creating sitemaps for site which has more than 500 Sub domains. Page varies from 20 to 500 in all subdomains & it will keep on adding in coming months.

I have seen sites that create separate sitemap.xml for each subdomain which  they mention in separate robots.txt file http://windows7.iyogi.com/robots.txt

XML site map eg for subdomain: http://windows7.iyogi.com/sitemap.xml.gz ,

Currently in my website we have only 1 robots.txt file for main domain & sub domains.

Please tell me shall i create separate robots.txt & XML site map file for each subdomain or 1 file. Creating separate xml for each sub-domain is not feasible as we have to verify in GWT separately.

Is there any automatic way & do i have to ping separately if i add new pages in subdomain.

Please advise me.

The more important, and URGENT issue is why are there so many subdomains, and why are there going to be more?  That's got to be one of the most serious and potentially harmful things you could do to your SEO efforts unless it's an extremely rare situation that justifies the tactic.

Hi Alan, i recently joined this co & i can't change the whole structure.

I believe they have created virtual sub - domains & Moreover site traffic is growing at a great rate so they can't think of changing structure.

Last month it has been ranked as 20th Most visited website in India, so things are pretty fine. Moreover it's an education website and students can easily remember Subdomain URL  eg: http://gmat.abc.com . also direct traffic to these sub domains is very high. So now how should i solve problem of XML sitemap

Okay with this little bit of information it does sound like it might in fact be legitimate.  If it is, then the best solution is to work with the development team to automate the creation of each sitemap.xml file, and have them submitted to Google automatically, I know this is possible because I use the google Sitemaps plug-in for WordPress - and it automatically submits to Google and Bing.

How it does that I do not know. That's up to smart web developers to figure out and replicate.

Yea in wordpress that option is available, but we are using Ruby On rails platform, so i am not sure whether we can do or not.

For eg http://windows7.iyogi.com/sitemap.xml.gz  they use Wordpress CMS & it's mentioned in page that

"It was generated using the Blogging-Software WordPress and the Google Sitemap Generator Plugin by Arne Brachhold."

Anyway thx for ur help i will speak to my smart developers, let's c what they can do
