What are the SEO implications of a CNAME?
-
(please ignore ridiculousness of hypothetical situation)
Lets say Amazon had a food division which was at food.amazon.com. I partnered with Amazon's food division and now food.amazon.com will point to my website (food.com). Amazon adds a CNAME record so food.amazon.com resolves to food.com. If food.amazon.com has built up significant page rank / domain authority, will food.com be getting those benefits? Also, lets say food.amazon.com/rice has a lot of PR / authority -- will food.com benefit from the value of those internal pages?

In addition to what Tyler said about the subdomain having no impact, the issue is that CNAME isn't actually redirecting anyone. So the traffic that is coming to food.amazon.com isn't really directing to food.com. It's merely renaming that page url.
In the event that you set it up that way, then sometime later removed the CNAME, and started food.com off on it's own, you would not inherit any of the domain authority from food.amazon.com. You'd essentially be starting from scratch with food.com.

The subdomain is like a completely different domain and has no impact on the tld.

WordPress Sub-directory for SEO
Hi There, I'm working on a WordPress site that includes a premium content blog with approx 900 posts. As part of the project, those 900 posts and other membership functionality will be moved from the main site to another site built specifically for content/membership. Ideally, we want the existing posts to remain on the root domain to avoid a loss in link juice/domain authority. We initially began setting up a WordPress Multisite using the sub-directory option. This allows for the main site to be at www.website.com and the secondary site to be at www.website.com/secondary. Unfortunately, the themes and plugins we need for the platform do not play nicely with WordPress Multisite, so we started seeking a new solution, and, discovered that a second instance of WordPress can be installed in a subdirectory on the server. This would give us the same subdirectory structure while bypassing WordPress Multisite and instead, having two separate single-site installs. Do you foresee any issues with this WordPress subdirectory install? Does Google care/know these are two separate WordPress installs and do we risk losing any link juice/domain authority?

WordPress Themes and SEO
I am helping out a client with updating their website.
Intermediate & Advanced SEO | | cangelmarketer
The theme they currently have hasn't been updated in ages (I am going to guess years). Would there be a difference in updating to the most recent version of their theme and changing them to a completely different theme? Or because they update in the current theme is so large anyway, it won't make a difference in terms of SEO. The reason I ask is that they don't know their Themeforest details to log in and download the most recent version of the theme, so they would have to re-purchase it, and with the hosting, they have access to a range of themes includes in their package.
