Does a CDN affect search rankings?
-
I feel kind of stupid asking this, but if i use one it would speed things up quite a bit. It is for a ecommerce website, any guidance on this would be awesome!
-
Google officially said the site speed is a SEO factor which, when implemented, will affect 1% of SERP results. This gives some idea of the scope of it's relevancy. (not saying 1% is either high or low, this is all very subjective)
Having said that, beyond speed improvement, CDN provides other SEO related benefits.
I've actually just published a 2-part Blog post that investigates SEO & CDN related myths and talks about CDN and SEO benefits, I hope you`ll find it useful. it should answer all questions:
Part 1: SEO & CDN Myths
Part 2: SEO & CDN benefits -
I use a CDN and have never seen any impact on my SEO. As long as your HTML is served off your domain you're fine.
If you're using AWS Cloudfront you can set up a CNAME so that your content comes from, say, images.mydomain.com instead of xyz.cdn.com. Helps obscure it from visitors and looks a bit neater.

Using a properly configured CDN will not have any negative effects on SEO. It can have positive effects on your rankings by offering faster page loads.
With Google's current system, you would not see a SEO benefit per se. If your current site is deemed slow by Google, you could have your current speed penalty lifted.
Moving to a CDN will surely provide a better user experience. Google is constantly adjusting it's algorithms in chase of the best user experience, so this is a chance for you to get ahead of the game. It is reasonable to think in the future Google may consider site speed as a ranking factor.
Two other suggestions regarding setting up a CDN:
-
you need to be very conscious of your cache settings. You could make a change on your site and users will not see the change if you do not ensure that change is propagated throughout your CDN
-
try to include all files which would benefit from a CDN. I have seen some sites just add their videos and image files to the CDN. Custom Javascript, CSS files and so forth can all benefit from CDN. PageSpeed and YSlow are two great tools for optimizing page loading times.
-
-
As far as I know, the urls of your additional resources such as images, css, and scripts shouldn't affect your SEO either way.
-
But, does the use of a Content Delivery Network (cdn) itself affect seo? For example my pics / code will be hosted differently. Just kind of confusing to me since I'm used to URL structure being: mydomain.com/images/pic.jpg instead of xyz.cdn.com/2523/myname/pic.jpg. Is this even something to be concerned about?
-
Site speed is only relevant when your site is extremely slow. Google doesn't penalize you unless your page load time is excessively long. You won't get a boost in rankings by speeding up your site.
With that in mind, Site load times do affect your user experience, so you may notice a lower bounce rate, more pages per visit, and possibly a higher conversion rate.

Google image search filter tabs and how to rank on them
I have noticed Google image search has included suggestion tabs (e.g,. design, nature... when searching background) on the top of the image search.

Are there specific meta tags I can add into my images so that my images will show up on each tab?
Do those filters just show content based on image keywords or something else? IRme7gQ0 -
Can an external firewall affect rankings?
For security reasons we are now routing traffic through an external firewall cum CDN. Our server and domain IPs remain the same, but any request is routed through an external IP, which then forwards the traffic. Would our rankings be affected because of IP changes? Thanks Sam

Does an Apostrophe affect searches?
Does Google differentiate between keyphrase structures such as Mens Sunglasses & Men**'**s Sunglasses? I.e. does the inclusion/exclusion of an apostrophe make any difference when optimising your main keyword/phrase for a page? Keyword explorer appears to give different results..... I.e. no data for Men's Sunglasses, but data appears for Mens sunglasses. So if I optimise my page to include the apostrophe, will it screw the potential success for that page? Thanks 🙂 Bob

How to remove my cdn sub domins on Google search result?
A few months ago I moved all my Wordpress images into a sub domain. After I purchased CDN service, I again moved that images to my root domain. I added User-agent: * Disallow: / to my CDN domain. But now, when I perform site search on the Google, I found that my CDN sub domains are indexed by the Google. I think this will make duplicate content issue. I already hit by the Panguin. How do I remove these search results on Google? Should I add my cdn domain to webmaster tools to request URL removal request? Problem is, If I use cdn.mydomain.com it shows my www.mydomain.com. My blog:- http://goo.gl/58Utt site search result:- http://goo.gl/ElNwc

My Rankings Keep Going Down - Needs some more ideas on why...
Hi Everyone, I have been working on the website www.PetsSpark.com for a while now. I used to be on the first page for many of my keywords, now I am lucky if i am on the 2nd or 3rd. I stopped my SEO efforts for about 3 months while making changes to the website, its whithin these 3 months that I started dropping from the first page. The biggest thing I notice is the "type" of website now ranking for my main keywords. Mostly Forums, Blogs, or Product Review websites. Take for instance Dog Tear Stain Remover. I used to rank at about #5 for this keyword and now i rank at #20. I'm not sure if my loss of ranking is a combination of things like who Google is letting rank now or if there is something wrong on my website, etc. Can anyone give me a little insight?? Please.... I will also be happy to give more information about what has been going on if needed.
