SEO implications of domain mapping (14 posts)

    I'm in the process of setting up a network of blogs with each child blog relating to a micro-niche of the same overall topic. I've opted to give each child blog their own domain with domain mapping for SEO purposes however I starting to thing this could actually have a negative effect on my SEO.
    I want to exchange links between each blog in my network but if each blog is obviously on the same IP address won't this hurt my SEO efforts?

    I'll be using directories rather than sub-domains for each child blog.

    Can someone please explain the SEO implications of this set up? (if there is any that is?)Remember I need to link between each blog because there all relevant to the same market, each child blog is related to a mini-niche.

    The same IP address is my biggest concern. Would I be able to get around this by using multiple dedicated IP?

  2. Eeeeh. Maybe. Unless you're linking back and forth a million times, I think you're okay. Stick to just a link a page, like in the sidebar, and you should be fine.

    You will not gain anything at all simply because this comes from the same network even if you have dedicated IP address for each "child blog".

    Maybe, just maybe you can use C Class IP address i.e. http://is.gd/jWopL.

    This is only possible solution, not my recommendation. I like to keep my SEO by the book :)

  4. if each blog is obviously on the same IP address won't this hurt my SEO efforts?

    Think of how many websites are on the same IP at a shared host.

    Hundreds.

    And Google doesn't care much about those.

    Really, I have looked into this at length, have talked to a *lot* of SEO people about this, and the only *only* way this is even remotely an issue is if you have hundred (hundreds) of links between the domains you're mapping and little to no links to those domains from elsewhere.

    So. Short version: you're fine. It's a non issue.

    Oh yes, I hadn't considered all the shared hosts with the same IP. Thanks everyone, you've reassured me it'll be fine. Just me being my usual over-paranoid self I guess. Thanks for taking the time to answer my question.

    Subdomain and Directories (folders) are treated pretty much the same by Google, that's why you decided to give each blog their domains and that's ok. Now please don't confuse shared IP address with the same network. I didn't say that he's not fine, all I said is that with this nothing will be gained for SEO purposes, that's all.

  7. Incorrect, Emil.

    SubFolders are seen as being the same website. SubDomains are seen as separate sites. If I could find google's spec doc on that, I'd link to it, but they moved things around. SubDomains are a little worse for SEO as you lose link juice. But really it works out in the end if you have good content and get linked to from enough places.

  8. @emil he was asking about mapped domains linked to each other on the same IP, not the SEO differences between subfolders & subdomains. :)

    @Ipstenu Let me help you with that, directly from Google that is:

    #subfolder-subdomain
    Q: Is it better to use subfolders or subdomains?
    A: You should choose whatever is easiest for you to organize and manage. From an indexing and ranking perspective, Google doesn't have a preference.

    It would be wrong for me to give any wrong advices when it comes to SEO, since I do this for a long time :)

  11. Please don't use URL shorteners. There's no need for that, it's not Twitter here :)

    This URL: http://sites.google.com/site/webmasterhelpforum/en/faq--crawling--indexing---ranking#subfolder-subdomain

    Is not Google's webmaster help. That's someone else's site. Google's is at http://www.google.com/support/webmasters/

    From this: http://www.searchenginejournal.com/subdomains-or-subfolders-which-are-better-for-seo/6849/ (which you've also linked to)

    For blogs, I prefer a subfolder (http://www.seomoz.org/blog/) because the link juice which is sent to that blog is going to be naturally distributed to that main domain, and other subfolders under the domain.

    [...]

    With a subdomain, the forum or blog will be listed as a separate entity in the Google search results, which is good for owning the results and one’s reputation management. However, Google and other engines will generally not list more than two of these subdomains in the search results, unless those subdomains can prove to Google that they are independent and relevant entities.

    Wanna talk abotu Matt Cuts on this? Read http://www.mattcutts.com/blog/subdomains-and-subdirectories/

    Yes, it's a 'wash', but even he points out

    For several years Google has used something called “host crowding,” which means that Google will show up to two results from each hostname/subdomain of a domain name.

    Also:

    A subdomain can be useful to separate out content that is completely different. Google uses subdomains for distinct products such news.google.com or maps.google.com, for example.

    They are different, SEO wise, and there are reasons to use them and reasons to not. But they're different and will be reflected differently on Google Search.

    I like short URL, but no big deal, I will not use them anymore ;)

    You can't classify Google Sites from Google Webmasters differently, simply because they have the same meaning and they're from the same site/company.

    However here's the link from Google Webmasters

  13. Sure I can. I have a site on sites.google.com. Doesn't make me google :)

    No preference is not the same as handled differently. (Best answer is not the same as official answer. Just means the OP of that thread marked that answer as best).

    But. To the topic at hand. Andrea nailed it :)

    Yes, but it came from Google Employee. Also check this out http://sites.google.com/site/webmasterhelpforum/en/ is not members site.

    Welcome to the companion site of the Google Webmaster Help Forum.

    Anyhow I think that we cleared this more than enough, anything beyond this would be pointless.

    No hard feelings :)
