Hey Jom,

I must admit I am not sure on the level of urgency to sort this problem out but personally I like to keep the duplication of content to a minimum.

There are multiple ways to sort this out but the most straight forward would probably be to add a rel canonical tag to your web pages.

Here is a good post discussing the faceted issues you can get from e-commerce site, here is SEOMoz's canonicalization guide and here is another seomoz blog post about e-commerce sites and the use of the rel canonical tag.

Hope this helps

I know we are talking basics here but have you made sure that you have your Adwords account linked to your Analytics account?

Also what I tend to do is to create seperate profiles for different types of traffic so that I can get an overview easily from the Analytics overview page and I find it easier than segmentation for reports. Here is what I do for those that are interested:

1. Returning Visitors Profile - create custom filter (include) on visitor type and type in "returning"

2. New Visitors Profile - create custom filter (include) on visitor type and type in "new"

3. Paid Visitors Profile - create custom filter (include) on campaign medium and type in "cpc|ppc"

4. Organic Visitors Profile - create custom filter (include) on campaign medium and type in "orgnaic"

5. Social Media Visitors - there are alot of filters on this one!

By doing this I have never had any data issues with one profile merging with another

The pipe and hyphen as already suggested are the way to go for pure usability and space saving for your title tag. In my opinion neither has a direct SEO advantage over the other however they both have a distinct advantage over other techniques. For me keeping the keywords used in the page title to the point help without any extra "by, or, and" breaks the keyword blocks both visually and semantically for the search engines. Now don't get me wrong I don't think this makes or breaks a good SEO effort on a page but for me it's certainly a preference.

Roger, The way we have approached this in the past was to go with separate TLD's using Magento. The main thing we did was to focus on a complete content rewrite for all pages including product descriptions to remove any possibility of duplicate content issues holding back the new sites and then set about localising with directories, webmaster tools and some low level link building. This seemed to do the trick in getting our .co.uk and .ie domains to rank above the older .com original site.
