Is it problematic for Google when the site of a subdomain is on a different host than the site of the primary domain?
-
The Website on the subdomain runs on a different server (host) than the site on the main domain.

Hi Martin,
This should not have an impact. Google is focussed on providing the best user experience, providing relevant content to its visitors, adapted to the device they are using & served in an efficient way (performance). How you organise your technical architecture behind it should have no importance. You would certainly not be the first to have a website running on different servers for different parts of the site. Typical example is a shop using Magento or some other e-commerce application on 1 host, and a blog on Wordpress on another host.
That said - there are still some points you need to take into consideration:
1. Server location - while probably not as important as it's used to - it's probably better to keep the location closer to your main audience (mainly because it can have an impact on performance. Quote from http://googlewebmastercentral.blogspot.com.es/2010/03/working-with-multi-regional-websites.html on location as ranking factor
Server location (through the IP address of the server) is frequently near your users. However, some websites use distributed content delivery networks (CDNs) or are hosted in a country with better webserver infrastructure, so we try not to rely on the server location alone.
If both servers are in the same location it should not be a problem.
2. You might consider to shift the subdomain to a directory as Google seem to prefer all content on one subdomain. You might want to check this WBF on subdomains vs directories: https://moz.com/blog/subdomains-vs-subfolders-rel-canonical-vs-301-how-to-structure-links-optimally-for-seo-whiteboard-friday
Even when using a directory - it is still possible to use two different servers.
Hope this helps,
Dirk

Google not indexing /showing my site in search results...
Hi there, I know there are answers all over the web to this type of question (and in Webmaster tools) however, I think I have a specific problem that I can't really find an answer to online. site is: www.lizlinkleter.com Firstly, the site has been live for over 2 weeks... I have done everything from adding analytics, to submitting a sitemap, to adding to webmaster tools, to fetching each individual page as googlebot and then submitting to index via webmaster tools. I've checked my robot files and code elsewhere on the site and the site is not blocking search engines (as far as I can see) There are no security issues in webmaster tools or MOZ. Google says it has indexed 31 pages in the 'Index Status' section, but on the site dashboard it says only 2 URLS are indexed. When I do a site:www.lizlinketer.com search the only results I get are pages that are excluded in the robots file: /xmlrpc.php & /admin-ajax.php. Now, here's where I think the issue stems from - I developed the site myself for my wife and I am new to doing this, so I developed it on the live URL (I now know this was silly) - I did block the content from search engines and have the site passworded, but I think Google must have crawled the site before I did this - the issue with this was that I had pulled in the Wordpress theme's dummy content to make the site easier to build - so lots of nasty dupe content. The site took me a couple of months to construct (working on it on and off) and I eventually pushed it live and submitted to Analytics and webmaster tools (obviously it was all original content at this stage)... But this is where I made another mistake - I submitted an old site map that had quite a few old dummy content URLs in there... I corrected this almost immediately, but it probably did not look good to Google... My guess is that Google is punishing me for having the dummy content on the site when it first went live - fair enough - I was stupid - but how can I get it to index the real site?! My question is, with no tech issues to clear up (I can't resubmit site through webmaster tools) how can I get Google to take notice of the site and have it show up in search results? Your help would be massively appreciated! Regards, Fraser

Approach for an established site looking to serve different content to regions in a single country/lang
Hi guys, I have an established site that currently serves the same content to all regions - west and east - in a single country with the same language. We are now looking to vary the content across west and east regions - not dramatically, but the products offered will be slightly different. From what i gather, modifying the url is best for countries, so feels like overkill for regions within the same country. I'm also unlikely to have very unique content, outside of the varied products, so I'm mindful of duplicate/similar content, but I know I can use canonical tags to address. I have a fairly modern CMS that can target content based on region, but mindful of upsetting Google re; showing different content to what the bot might encounter, assuming this is still a thing. So, three questions from an SEO perspective - Do i need to really focus on changing my url structure, especially as I'm already established in a competitive market, or will I do more harm than good? Is the region in the URL a strong signal? If I should make some changes to the url and/or metadata, what are the best bang for buck changes you would make? How does Google Local fit into this? Is it a separate process via webmaster tools, or does it align to the above changes? Cheers!!! Jez

Redirecting domain to the main domain (hosting cost?)
Hello Everyone, I have the following situation. There is main domain and a secondary domain that is related to the page on the main domain. I want to integrate the content of the secondary domain into the page on the main domain and redirect the secondary domain via 301 to that specific page. As i understand I can do it via .htaccess using rewrite mechanism. http://www.seomoz.org/learn-seo/redirection But the question is does it mean I have to keep paying for the hosting for the secondary domain? Because htaccess has to be located on the web server so I would need a hosting plan for it? Is that true? Is there any way around it? P.S. to avoid any confusion - I am talking about hosting plan - not domain registration fees

Best geotargeting strategy: Subdomains or subfolders or country specific domain
How have the relatively recent changes in how G perceives subdomains changed the best route to onsite geotargeting i.e. not building out new country specific sites on country specific and hosted domains and instead developing sub-domains or sub-folders and geo-targeting those via webmaster tools ? In other words, given the recent change in G perception, are sub-domains now a better option than a sub-folder or is there not much in it ? Also if client has a .co.uk and they want to geo-target say France, is the sub-domain/sub-folder route still an option or is the .co.uk still too UK specific, and these options would only work using a .com ? In other words can sites on country specific domains (.co.uk , .fr, .de etc etc) use sub-folders or domains to geo-target other countries or do they have no option other than to develop new country specific (domains/hosting/language) websites ? Any thoughts regarding current best practice in this regard much appreciated. I have seen last Febs WBF which covers geotargeting in depth but the way google perceives subdomains has changed since then Many Thanks Dan

New project old domain should I 301 redirect while new sites built
I just took on a larger scale e-commerce project and came across a tricky road block that I need some advise on. Ok I'm building the site from scratch and due to it's complexity it may take 3-4 months before I have it designed and coded. The client has a domain name that has some decent page/domain authority and I would hate to loose that while the sites being built. Currently I have nothing to display as his previous site got hacked and it was deleted by the previous web admin. Being that a blog has already been approved as part of the project I already installed wordpress to keep the domain fresh however here's the issue, I installed wordpress in a folder called blog and debating if I should 301 redirect or 302 redirect his index here? The blog will always reside in the blog folder even after launch. Will performing a 301 redirect pull all the juice away from my index page? I'm assuming yes. IF so what would occur once the project is complete and I make the ecommerce site live in the index page? Thanks in Advance! Mike
