Welcome to the Q&A Forum

It's not mandatory that your physical address should match with Who is Info. Most of the times domain are registered with some other address and site physical add is diff.

Publishing physical address in website will help you in building trust. Even when u do local listing of site google matches both address and it will help your website appearing in Google Local Listing.

Also if you see from  user point of view they will never trust of share credit card if site doesn't have physical address and even google has mentioned same thing after panda update that they don't like sites on which user doesn't trust or feel comfortable in giving there credit card details.

As per your Q i believe u r showing those first 10 snippets in 2 different pages within your site. If that's the case it can never be issue of duplicate content.

In any blog we show 4 or 5 lines summary at main page & remaining on another page when we click on "more option" so main page will also have summary. So go ahead and do it.

In My website we show summary of 1 article in 10 different related community to get better rankings, but till date we have never faced any penalty.

But if u r taking snippets from other site, then u can add Canonical tag to your page pointing to site from where u have copied content. In that case google know that u have copied content from another site.

It it's related to your filed, you will definitely get benefit from links

Category wise structure is alwaz a better option.

If your site is small than you can keep all pages in root folder, but as your site grows it would be very difficult for you to manage all pages on root & google will treat all pages at same level

go for 1st option.

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

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

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.

Our Site learnhub.com & Jumbotest.com saw 30% increase in Traffic after panda update.

If the search is for Company product or service, You can take little advantage by doing local listing of each franchisee. Except This content rewriting is only option as per my knol.
