Using a single sitemap for multiple domains
-
We have a possible duplicate content issue based on the fact that we have a number of websites run from the same code base across .com / .co.uk / .nl / .fr / .de and so on. We want to update our sitemaps alongside using the href lang tags to ensure Google knows we've got different versions of essentially the same page to serve different markets.
Google has written an article on tackling this:https://support.google.com/webmasters/answer/75712?hl=en but my question remains whether having a single sitemap accessible from all the international domains is the best approach here or whether we should have individual sitemaps for each domain.

If you have the different websites running with different languages (i.e. .com is English, .nl is Dutch, .fr is French, etc), then you should probably have a separate sitemap for each site.
If they are all the same language, and you just have the site loading with .com / .nl / .fr, then Google will see this as duplicate content and you should likely make changes to keep them a bit more separate...
Thanks,

Redirect multiple domains to 1 domain or not?
Hi there, I have client who has multiple domains that already have some PA and DA. Problem is that most websites have the same content and rank better on different keywords.

I want to redirect all the websites to 1 domain because it’s easier to manage and it removes any duplicate content. Question is if I redirect domain x to domain y do the rankings of domain x increase on domain y? Or is it better to keep domain x separately to generate more referral traffic to domain y? Thanks in advance! Cheers0 -
Sitemap: Linking horizontal pages on a sitemap that has a vertical hierarchy structure
I'm currently in the process of revamping a website and creating a sitemap for it so that all pages get indexed by search engines. The site is divided into two websites that share the same root domain. The marketing site is on example.com and the application is on go.example.com. To get to go.example.com from example.com, you need to go through one of three “action pages”. The action pages are accessed from every page on example.com where we have a CTA button on the site (that’s pretty much every page). These action pages do not link back to any other page on the site though, nor are they a necessary step to navigate to other webpages. These action pages are only viewed when a user is ready to be taken to the application site. My question is, how should these pages be set up in a vertical sitemap since these three pages have a horizontal structure? Any insight would be much appreciated!

Value of domain name for domain authority. Please help to figure out!
I am doing SEO for an appliance repair company. Their company website's domain doesn't have high authority, and I am going to increase that by link earning and content improving. I think a better domain name might also help me out. The current URL contain the word "appliance" but doesn't have "repair" in it. I am thinking a new domain that would contain both keywords will serve better. Could you please share with me your thought on this? Am I in the right direction, or not at all? I know Google penalizes mirror sites since this they are considered as duplicated content. I'll upload my content to the new domain and make the old one point to that new URL. I am wondering if canonical might help? Or 301 redirect will be a better solution? Any advise would be highly appreciated! Thank you!

Transfer a Main Domain to a Sub-Domain
My IT department tells me they want to transfer my main site domain, which has been in existence since 1999 as an e-commerce site (maindomain.com) to a sub-domain (www2.maindomain.com) or a completely new domain (newdomain.net). This is because we are launching a new website and B2C e-commerce engine, but we still have to maintain the legacy B2B e-commerce engine which contains hard-coded URLs, and both systems can't use the same domain. I've been researching the issue across SEOmoz, but I haven't come across this exact type of scenario (mostly I've seen a sub-domain to new domain). I see major problems with their proposal, including negative SEO impact, loss of domain authority/ranking and issues with branding. Does anyone know the exact type of impact I can expect to see in this scenario and specific steps I should go about to minimize the impact? Btw, I will be using Danny Dover's guide on properly moving domains where appropriate. Thanks!

Keyword in Domain or not?
My on page optimization grade is an "A" with the following factors; Factor Overview <dl class="scoreboard clearfix"> <dt>Critical Factors</dt> <dd>4 / 4</dd> <dt>High Importance Factors</dt> <dd>7 / 7</dd> <dt>Moderate Importance Factors</dt> <dd>8 / 9</dd> <dt>Low Importance Factors</dt> <dd>11 / 11</dd> <dt>Optional Factors</dt> <dd>5 / 5</dd> </dl> The main thing I appear to be missing is keywords in my URL. How truly important is that in today's SEO world and how much time or ranking would be lost if I do not have control to change the external links to my website if I decided to migrate to a keyword relevant url?

Sitemap with References to Second Domain
I have just discovered a client site that is serving content from a single database into two separate domains and has created xml sitemaps which contain references to both domains in an attempt to avoid being tagged for duplicate content. I always thought that a sitemap was intended to show the files inside a single domain and the idea of multiple domains in the sitemap had never occurred to me... The sites are both very large storefronts and one of them (the larger of the two) has recently seen a 50% drop in search traffic and loss of some 600 search terms from top 50 positions in Google. My first instinct is that the sitemaps should be altered to only show files within each domain, but am worried about causing further loss of traffic. Is it possible that the inclusion URLs for the second domain in the sitemap may in fact be signalling duplicate content to Search Engines? Does anyone have a definitive view of whether these sitemaps are good, bad or irrelevant?
