You have gotten some great answers. What I would like to add is, reverse the process of thought a bit by thinking where your customer is. Go list with directories where your customer might be looking for a company like yours. If you are looking to register with any directory, do it for the value of the traffic or exposure that directory might be able to pass on to you and not the SEO/link value. If we do that, you'll get the best ROI and it'll be a safer approach in terms of SEO in 2013. I hope this helps.

Yes, as Ryan said, this is the nature of the internet. Just like you can write about anything, anybody, you can create a link to anybody and just to clarify, the block that Ryan is talking about is essentially that if someone linked to you, you could "technically" setup a block so anybody visiting your website from that link, would not be able to access your website..but it would still get counted as a link from that website to yours.

I think it makes sense to let the user select the currency and see the changed price or use the geolocation to automatically display that price. It would be a considerable amount of time and effort to try and make the different set of pages unique, so in short it does not make sense to make different urls for different currencies. However, if you plan in the future that you are trying to translate the content in other languages as well, then it's a different story. In that case you are targeting different countries and it's best served by country level domains for the countries you are targeting. I hope this helps.

I actually remember Lore from a while ago. It's an interesting, easy to use FAQ CMS.

Anyways, I would also recommend implementing Canonical Tags for any possible duplicate content issues. So whether it's the print or the web version, each one of them will contain a canonical tag pointing to the web url of that article in the section of your website.

I agree with Neil. It's not bad, just a good user practice to keep them lowercase so that's there's no confusion. The best bet for you would to be to use a consistent format and mimic that in your canonical URLs so only that variation gets crawled and indexed.

I am not sure whether that's a good solution or not, but look into the option of providing no product description in your feed. Just the Product Name, Categories, Tags/Attributes etc. Maybe a shorter version of the description...First 100 characters maybe ? That would at-least protect from future datafeed consumers....

Sounds like your client clearly needs the SEO / Webmaster Best Practices cleared out and taken care of. Help the Search Engines Rank your website. Provide them enough information that they can rank you. Too little or Too much, both can lead to "no benefits".

So yes, I would optimize those page titles to both SEO and User Friendly. If nobody is able to see those 210 characters, why have them. Also work on a SEO and User Friendly Description as well as H tags if and as needed.

I'd also recommend to look at your blog not just for SEO reasons as a link that helps towards SEO, but as your customer acquisition and brand awareness tool. The SEO Benefit is a freebie (maybe an essential freebie) that you get out of it. So if you think of this blog with this attitude, you'll end up building a great blog with tons of content, great readership and so on.

And to directly answer your question, honestly since it's just 1 domain name, I would not worry about it too much. As donford set, you'll technically get a little bit more value if this blog was hosted on a different Class C IP. Other then that, I wouldn't worry much about changing registrars etc. Not a big deal, however if it bothers you and you'd like to shift the domain to a different registrar, that's okay as well. Again, I would not stress much on this small issue.

I hope this helps.

You are not, you are absolutely right on the way you are thinking. Except that I have not seen any of that "root domain" advantage get passed onto the sub-domain level.

If your main-domain is a brand domain, maybe you could do the sub-domain and I understand your reasoning behind it, however I would not expect the sub-domain to trickle through the SERPS and get the domain authority and trust like your root level domain does.
