Will using CDN Affect SEO?
-
I'm got a website with a slider and each of the 6 slides has a 5-second video background. The website is B2B and the user profile for the website is employees at Fortune 1000 companies in the United States using desktop computers to browse. The videos are highly optimized and we did testing using various browsers and bandwidth connections to determine the videos loaded fast enough on down to a 15mbit/s connection (which is pretty low by today's average U.S. business bandwidths.)
We tried hosting the videos on Vimeo and YouTube but it caused issues in the timing of the slide show display. (I've not seen any other website do what we do the way we do it. Most sites have a single video background with a single text overlay on top.)
The downside to this is that loading all those videos produces a lot of bandwidth usage for our server. The website is serving a niche service industry though so we're not exceeding our current limits.
I'm wondering though might there be some benefit to hosting just the video files on a CDN? Obviously that would mean lest bandwidth usage for our server, and possibly quicker load times where the CDN server is closer to the user than our server. But are there benefits or downsides from an SEO perspective noting that I'm proposing only putting the videos on the CDN, not the entire web page.

In theory as per Joe using a CDN can certainly influence your site speed load, however I found their are a few caveats to this.
Firstly are you serving content in the same country/content to your audience and does your CDN have a node in this location to allow a faster pull of content. The speed gain may only be helped if this is the case.
Second, can your CDN serve content via SSL be it an installed or shared SSL.
And can your CDN serve via HTTP2 for simultaneous loading of files in parallel with one another. All of this can certainly affect your SEO, but hopefully the gains are enough to actually have a positive influence.
For Videos - my favourite is still actually Youtube, it can boost your own following and don't forget Youtube is the second largest search engine that I am aware of. Hosting and having content here can only be an added benefit.

The quicker your site loads the more rewarded you'll be - SEO wise, but, read the fine print when you research for a service provider, beware of any mention of down-times! This could be detrimental.
My first step would be to optimise the video, see if/ how that speeds things up.

Multi-Store SEO
I am currently developing a website which will have a multi-store function, i.e. one for US & ROW customers and one for UK & EU customers. The domain names will be along the lines of: Original domain: www.website.com UK & EU domain: eu.website.com US & ROW domain: us.website.com When a customer visits the website they will be redirected to one or the other depending on their location. Can anyone see any problems which this may cause in respect to SEO? I know there may be a duplicate content issue here also, how should I best deal with this?

How will this affect the rankings and traffic of the new site once this happens?
Hi, we will be moving a clients’ site address from one domain to another and will of course be doing 301 redirects and notifying Google of the site address change in WMT. The problem is, that at some point in the future (say 3-6 months), the old domain will be going live with a new site as the current client does not own the domain and the owner will be wanting it back unfortunately. How will this affect the rankings and traffic of the new site (new domain) once this (old domain with new site) happens? Will the site address change be enough to keep the rankings but it will lose backlink traffic? Or will rankings go down since the 301 redirects will in essence no longer be in affect? Many thanks for your help in advance.

How does having multiple pages on similar topics affect SEO?
Hey everyone, On our site we have multiple pages that have similar content. As an example, we have a section on Cars (in general) and then specific pages for Used Cars, European Cars, Remodeled Cars etc. Much of the content is similar on these page and the only difference is some content and the additional term in the URL (for example car.com/remodeled-cars and /european-cars). In the past few months, we've noticed a dip in our organic ranking and started doing research. Also, we noticed that Google, in SERPs, shows the general page (cars.com/cars) and not the specific page (/european-cars), even if the specific page has more content. Can having multiple pages with similar content hurt SEO? If so, what is the best way to remedy this? We can consolidate some of the pages and make the difference between them a little clearer, but does it make that much of a difference for rankings? Thanks in advance!

CMS generating thousands of links, will it hurt my SEO?
I've shifted my static (HTML) eCommerce website to Magento. I am facing serious problem, my website has total 20 products (each product has canonical URL) , I was surprised to see thousands of links indexed in Google as well as in my webmaster Crawler stats, later on I removed all from webmaster tool and marked as fixed, also blocked crawlers to crawl on those specific directories through robots.txt file. Now my question is will these urls still effect my website's SEO? As they still exist and accessible but blocked for crawlers. And is there any better way to block them other than robots.txt.Thanks

Predictive SEO
Hello all, I am trying to perform a predictive competitive SEO analysis to estimate what I will need to do to surpass my competitors. I am unsure of how to do this and would like some advice or link to an article. What I am trying to do is predict where I can rank in three months, six months and one year as well as what I need to do compared to my competitors. Specifically also to estimate how many links I would need to acquire to both my page as well as domain. I have already pulled my competitors domain links, page links, and age. Adam

Do interstitials hurt SEO?
If you go to www.homeportfolio.com and click on one of the links in the footer. you'll notice you are presented with an interstitial. Can you tell me if that hurts our SEO and if we lose any link juice or suffer in any other way as a result of this linking method? my main concern is whether having anchor text that says "bathroom ideas" that goes to an interstitial that doesn't mention bathroom ideas is non-relevant... even if it refreshes 12 seconds to a page that is.
