      Does CDN impact on SEO or not?

      There seems conflicting ideas as to whether they impact positively or negatively, I realise that if the page loads quicker this is a good thing for SEO and usability of course.

      Does Google see CDN as just cheating and a get-around for not doing the work from the ground up and using good hosting etc?

      Do you have any direct experience?

      All constructive input much appreciated!

          I doubt that Google is seeing using a CDN as cheating - it is one of the factors which helps increasing the speed of the site and increase user experience. It would be an ideal world if you could get a 100% score on Pagespeed Insights and all A scores on webpagetest.org - but you have to start somewhere, and adding a CDN is normally one of the easier things to do. So it's certainly not cheating - rather taking a step in the good direction.

          Apart from that, Google is offering a CDN itself (https://cloud.google.com/dns/docs).

          rgds,

          Dirk

            Hi Egol,

            You can mask the url of the CDN behind your own url - so rather than displaying d3vam04na8c92l.cloudfront.net/imagename.jpg (the example is Cloudfront but it's possible for most CDN's) it could be something like images.mysite.com/imagename.jpg - so links to these pages would still be beneficial to your domain rather than the cdn.

            Dirk

              I like the answer given by Nitin.  I agree with the speed benefits and that has tempted me to consider CDNs.

              I also have a question to toss out....

              Let's imagine that I have a site with very popular images or very popular pdf, ppt, doc, etc files.  If those are on my domain then google can easily see that popular images in image search are associated with my domain.  Also if people embed my images or hotlink my images or link to my pdf ppt doc, etc files then google can see that activity and popularity is associated with my domain.

              Many sites have enormous investments beyond typical webpages.  Google does rank pdf ppt doc etc files.  They accumulate pagerank and have the ability to pass link benefits.  In addition, they can build brand mention popularity, as an example, people can say... "Look at this great photo on egol.com" and that mention, I believe, can provide ranking benefit, advertising value for your domain.  If people who find your image or other document instead say... "Look at this great photo on xyz123cdn.com" then that strips those benefits from my domain.  It strips type-in traffic from my domain.

              Does anyone know of any testing or statements from Google that address how image and information files work when used on CDN.

                Hi,

                Generally, people advice to use CDN for serving static content very fast on your site, that helps you improve your page speed and hence, there it adds value from SEO & UX perspective.

                Now, the definition of CDN will help you understand how exactly it can help you improve your page speed. So, here you go:

                "A CDN is essentially a network of geographically dispersed servers. Each CDN node (also called Edge Servers) caches the static content of a site like the images, CSS/JS files and other structural components. The majority of an end-user's page load time is spent on retrieving this content, and so it makes sense to provide these "building blocks" of a site in as many server nodes as possible, distributed throughout the world.

                When a user requests your site, the node closest in proximity to user will deliver the static content, ensuring the shortest distance for the data to travel (reduced latency), therefore providing the fastest site experience."

                Also, check the attached image to understand it well. Hope this helps 🙂

                  SEO on dynamic website

                  Hi. I am hoping you can advise. I have a client in one of my training groups and their site is a golf booking engine where all pages are dynamically created based on parameters used in their website search. They want to know what is the best thing to do for SEO. They have some landing pages that Google can see but there is only a small bit of text at the top and the rest of the page is dynamically created. I have advised that they should create landing pages for each of their locations and clubs and use canonicals to handle what Google indexes.Is this the right advice or should they noindex? Thanks S

                  Best SEO for table in mobile view

                  I'm wondering what the best way to present a table for mobile view in terms of SEO? It's a complicated table (not simple rows & columns but also col spans) which doesn't work with any responsive techniques I can find. I can offer different content for desktop / mobile so desktop is OK. But what's the best way forward with Google for mobile? I could offer a jpg or simply an explanation to revisit the page on desktop, but neither of those options  seem particularly Google-friendly?

                  Creative Commons Images Good for SEO?

                  I've been looking at large image packages through iStock, Getty, Fotolia and 123RF, but before spending a bunch of money, I wanted to get some of your feedback on Creative Commons images. Should be worried that something found on Google Images > Search Tools > Usage Rights section can be used without issue or legal threats from the big image companies so long as they are appropriately referenced? AND will using these types of images and linking to the sources have any affect on SEO efforts or make the blog/website look spammy in Google's eyes because we need to link to the source? How are you using Creative Commons images and is there anything I should be aware of in the process of searching, saving, using, referencing, etc? Patrick

                  If you have an unlimited SEO budget, what would you do?

                  Here's a bit of background information: I've achieved the targets and is now being offered what is essentially an unlimited budget. I have a nice list of ideas but thought I would the brilliant people here at the SEOMOZ community what they would do. So as to promote as much response as possible, I'm going to keep my list to myself for now. And by "SEO", I mean I can do things like content strategy, blogging, infographics, etc. Shoot away!

                  Is DOCTYPE important for SEO?

                  Hello fellow Mozzers. I am just having a brief look at a potential clients website before speaking to them tomorrow and whilst looking at the source I noticed that they don't appear to have a clear definition for their Doctype. All the have at the top of each page is I have to admit that Doctypes aren't my strong point but I know that they are normally slightly more descriptive than this. Can this have any effect on rankings? or is this just an issue for W3C validation? Thanks 🙂

                  Iframe redirect bad for SEO?

                  Hi, I have a website (http://www.blowingminds.de) wich I put a spreadshirt shop into via iframe. The thing is I am not sure on how the iframe effects my SEO? Can I just optimise the main domain for search? Well I want the spreadshirt shop to be found under the domain name (www.blowingminds.de) but the only real way to do it is by implementing an iframe because each spreadshirt shop has its own subdomain eg.: blowingminds.spreadshirt.de but the only real way to do it is via iframe, as they do not offer a complete domain redirect. (Or have I overseen some other way?) I hope you guys can help me on this one 🙂 Thanks in advance. Malte
