Does using a sub-domain lessen the effectiveness of your main domain?
-
For example a website without a blog and is a simple html site with no blogging capabilities. We go out to Blogger or Wordpress and set up the blog portion of the website using something like blog.yourdomain.com. Does this make a difference SEO wise? Is is more effective to be sure that you are using the main domain and not a sub-domain? I have heard both sides before but can't seem to find the concrete answer. Thanks for any advise out there.

Actually it's a bit more complex than Rafi explains.
If the main site is an ecommerce site (sells products), it's okay to have the blog on the main site unless you end up with a high volume of content on the blog that can weaken the "purchase" intent of the main site. In that case, the blog on a sub-domain is actually somewhat better because it separates the "informational" intent out and can in turn build up a stronger authority signal as "informational" as a sub-domain. But only if you drive a lot of traffic, engagement and links to the sub-domain.
If the topic is isolated to a niche topic not generally strong on the main site, that's another valuable reason for the sub-domain path. Again, by isolating it within a sub-domain you're preventing dilution of the topical focus of the main site. That also applies if you have products or services that you can build up enough content within that niche to justify an entire sub-domain.
If the main site is informational and the blog is informational, and there is a lot of cross-topical relationshps, it's best to keep the blog as a folder/directory within the main site - in this scenario you get more value by going this route because of the commonality of intent and topical focus.

Hi there,
Nothing makes a difference from an SEO standpoint unless you have good content in it. So, if you host a blog on your domain with good and relevant content that complements or goes hand-in-hand with your domain's theme or line of business, it would definitely add up to the strength of your domain overall going forward. Though its a sub-domain, treat it such that it is an entirely different domain, optimize it the way you would do any other domain. Personally, I would host the blog on my domain itself so that I don't run in to the weird world of cross linking problems especially when its hosted on the same IP address that my domain is hosted on. So if its a business need to have your blog separately, its better to go with a dedicated IP and also make sure it belongs to a different class C IP. We faced issues related to cross linking no matter how clean we tried to maintain them both. Please note that this is purely out of my experience.
Best regards,
Devanur Rafi.

Back links with instant effect?!
I realise this is incredibly controversial! And I also realise I’ll get a ton of trolls pulling me to shreds but… I’m in need of running a short-term experiment, but to do the experiment I need to get a test site ranking high very quickly (not worried about if it gets penalised, it is only a short-term test).

Redirecting main www. subdomain to new domain. Can you then create a new subdomain on the old domain?
Hi there, The scenario is this: We have been working on a rebrand and have changed the company name So, we want to redirect www.old-name.com to www.new-name.com However, the parent company is retaining the old brand name for corporate purposes So, in an ideal world, we'd be able to keep www.old-name.com active - but clearly that would sacrifice all of the authority built up over the years, so we do have to redirect the main www. subdomain in it's entirity. However - one suggested solution is to redirect www.old-domain.com to www.new-domain.com... but then create a new corporate subdomain: for example, business.old-domain.com business.old-domain.com will not be competing with the new site on any service/product related terms; it will only need to appear in SERPs for the company name I'd appreciate some thoughts on this, as I've not done this before or found any examples of anyone that has. Is that a massive risk in terms of sending a confusing message to Google? Thanks for your help

International Domains for SEO
My company is international and we have websites for each country with Country Code Top Level Domains (ccTLD). I am in the US and I am seeing that other countries such as Costa Rica and Germany are ranking above us in search results. I thought Google automatically geo-targeted users by default and therefore I should only get .com or US results. Any idea why other countries would rank above our site?

Menu & Sub menu structure - section specific sub menu?
Hi, At present I have a set of regions across the nav bar with drop downs for towns within these regions. This totals about 60 links. This set up is pretty much site wide and the site ranks well for many of these towns. However, this is quite a lot of links per page (without the page specific/content links) and I am wondering about having just a horizontal sub menu of towns appear below the nav bar only specific to the selected region. Do you think cutting down the number of menu links will be beneficial to the content page's ranking. Sorry if that isn't very clear, can't think of a better way of putting it. TIA,

Website domain hosting and set-up for foreign domains?
Hi, I am just wondering what the best practice is for marketing a business in two separate countries? I have a new client that wants me to create their website targeted at the UK market which for me is normal but they also want to target Australia (Probably couldn't get any further away) My initial thoughts are that the business would need two separate websites. The first one in the uk and the second website hosted on servers in Australia with different content. Is this correct? or does anyone have any advice which may simplify getting this thing off the ground. Thanks in advance.

Cookies and redirects - what are the negative effects?
I am advising a client who wants to streamline their online customers experience through the use of cookies. The first time someone visits mysite.com, they will visit the normal index page, and on that page will be asked to identify themselves as a Personal or Business customer - and taken through to a relevant page. This will result in a cookie being added. The next time they come back to mysite.com, the cookie will automatically direct them from the index page to mysite.com/personal/ or mysite.com/business/. My question is, what are the SEO implications of this, especially given the fact the index page is their primary landing page for almost all organic traffic? Bots I realise that googlebot etc do not store cookies, so this should result in no change from the bots perspective (i.e. no redirect) but is it that simple? In effect we'll be showing the bot one thing and second time + visitors something else. Is this not effectively cloaking? All advice gratefully received!
