Thanks Martijn,

I actually want to know what would you do for the 404 page itself. It is something like:

www.mainurl.com/404.html and for some reason this started to create some other links such as

www.mainrul.com/404.html?aspxerrorpath=/contact-office.aspx

Do you think I should add 404 page and subpages to Robot.txt ?

Thanks!

Hi,

got different opinion on this so i wanted to double check with your comment is.

We've got /404.html page and I was wondering if you would add this page to robot text so it wouldn't be indexed or would you just add no index tag? What would be the best approach?

Thanks!

I had that argument with a client once and i manage to persuade them not to go ahead with it as they had .com and .co.uk .

.com is international so i think it did make sense not to use .eu but in your case, if you don't have .com then probably you need to look at which countries you want to target. If your client is UK based and if they target client from all around EU, then it might make sense to use .eu as you have very little chance to target someone in Italy with co.uk or .com.fr domains. If you are targeting only UK and FR then, you don't need .eu. It will just duplicate your work.

They are two separate things and I would recommend to have both if you can, as Like button is get people to share your home page with their friends and Like Box is to get them to join your Facebook page which is important have more followers for retention and branding purposes.  From SEO point, it is important if people share your page but you also need to get people to share your future posts which is also important and to do this you need to make sure you grow your followers on Like Page. Like box on home page would be good way to get more followers.

I hope that helps

You can either create a new Webmaster account for Subdomains then you can track the traffic for each subdomain or you can use the tracking of the main URL on Subdomains. Depends on how you want to track the results.

Regarding, creating sitemap, that depends on what you are trying to achieve with your sub domains. If you are creating proper websites under subdomains then sitemap is recommended. If they are just a landing page then you won't need one.
