Welcome to the Q&A Forum

As I think if you have a Business website then the Product FAQ at the below. Because if a Person looking for a Product, then it finds the faq on the same page will help you to grow your sales as well as reduces the use of Email Support or Call Support.

Thanks, Jordan.

You do need to make sure you do a 301 redirect to the pages without extensions.

Great question!  I think this is a question that a lot of people are thinking about right now.  I know we've thought about it recently. This question, definitely has a lot to do with company culture.  Remember that the rel=author tags connects to personal pages not company pages, so the important question is, do you still want people who no longer work at your company to support it?  Obviously Google's rel=author does have an SEO impact, however if these people were unhappy when they left the company having their friends see your company in Google search with an image of them might leave a bad taste in there mouth. If you don't have this problem and don't think people will mind, I say go for it, especially if they are G+ users.  This will affect the searches of people in the Authors circles and hopefully have an overall impact on your search volume.  It will help authors who are no longer with your company, through branding and will help your company overall, so it will be a win/win for both parties.

The purpose of the crumb trail to let users know where they are and provide an easy method to Navigate back along the path they have taken. In which case, as a user there is a particular place I expect to see the crumb trail, usually at the top of a content block directly under the page header. If its not user friendly I wouldn't expect it to be beneficial to SEO either. Loving the design though

I would redirect the brand site to the company site.  I'd place it into a folder.

LOL Yes you could look at it the other way around. If they write blogs in the company's time, tell them to rel=canonical to the corporates blog version.

If they are very technical, just write down the specs or steps that you are discussing at the side, kind of like a guide you can follow while seeing the video.
