Welcome to the Q&A Forum

The answer depends on a few factors. Step back and take a fresh look at each page. Don't think of it as the page's author or webmaster. Think about it from the view of a user who searched for a phone and landed on the page. How much information is what the user was hoping to find? How much of each page is repeated keywords that have nothing to do with the page's content? How much of each page is duplicated information that will be found on every other page in your site? It comes down to percentages. I do like your pages. They are clean, easy to navigate and well-presented. The only concern I have is the sidebars with the points mentioned. I do not see how Google could have any concern with your content unless you have other duplicate pages on your site of the information. I just took another look at the links you offered. While there is some duplication, it really is not much.

There are a lot of different reasons why they chose this way to place the blog (software, hosting-limits, easiest out-of-the-box setup, etc..) It does not do too much "damage" though. Having a sub-folder is the best-practise but using sub-domain is the second best. It would be "harmful" if they used another domain, which is not the case.

Hi Ryan, I have posted the stats for that further down in this thread
