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.

Website ranking declined after connecting to CDN
Hi! We are trying to rank https://windowmart.ca for various local search terms. Our head office is in Edmonton where we try to rank https://windowmart.ca/edmonton-windows-doors/ for such terms as "windows Edmonton", "replacement windows Edmonton", "windows and doors Edmonton" as well as others. The website was the leader in its niche for around 2 years. Then we've got some server related issues, moved to a new server and connected CDN Nitropack that really improved our google speed test results. Recently we noticed that our rankings started to drop. Do you know if Nitropack can negatively effect local SEO rankings? Thank you!

Company name ranking
Hi all, I hope somebody can share their thoughts on the below. A web designer launched my client's new website and I have been tasked with the SEO. I was approached with an immediate problem, www.clientswebsite.co.uk was ranking 9th for their company name after being indexed by Google. The search results above www.clientswebsite.co.uk were related to my client but not all, for example a direct competitor was also ranking. I have been working on the SEO for 2-3 weeks and I just managed to get to 3rd position for the company name, and then www.clientswebsite.co.uk disappeared from page 1! And now instead, an irelevant sub page is now ranking for the company name on page 2 (a contact page). I have checked and the home page is still indexed (did a site: check). The only problem software picks up is a redirect chain (http://homepage -> http://www.homepage -> https://homepage) the web developers said it wouldn't impact rankings (when I asked them to edit the htaccess file to fix it) I've listed below the SEO tasks I completed whilst attempting to rank the company name: I set up analytics and webmaster tools, in which I set up preferred domain (www) Added a sitemap Edited meta data making sure company name was included I contacted the websites above www.clientswebsite.co.uk that were relevant and asked them to place a link linking to their new website, I was successful with a couple of these. I placed www.clientswebsite.co.uk on all of their social media profiles I reformatted headers on their home page, making sure the H1 included my client's company name I found 2 extra versions of my client's home page (not exact copies, but very similar content) that had been published, so I decided to 301 redirect these to the correct home page Activated SSL and forced to HTTPS I would really appreciate it if anyone could share their thoughts here, whether it be explanations or possible solutions Adam

Google not Indexing images on CDN.
My URL is: https://bit.ly/2hWAApQ We have set up a CDN on our own domain: https://bit.ly/2KspW3C We have a main xml sitemap: https://bit.ly/2rd2jEb and https://bit.ly/2JMu7GB is one the sub sitemaps with images listed within. The image sitemap uses the CDN URLs. We verified the CDN subdomain in GWT. The robots.txt does not restrict any of the photos: https://bit.ly/2FAWJjk. Yet, GWT still reports none of our images on the CDN are indexed. I ve followed all the steps and still none of the images are being indexed. My problem seems similar to this ticket https://bit.ly/2FzUnBl but however different because we don't have a separate image sitemap but instead have listed image urls within the sitemaps itself. Can anyone help please? I will promptly respond to any queries. Thanks

Removing site subdomains from Google search
Hi everyone, I hope you are having a good week? My website has several subdomains that I had shut down some time back and pages on these subdomains are still appearing in the Google search result pages. I want all the URLs from these subdomains to stop appearing in the Google search result pages and I was hoping to see if anyone can help me with this. The subdomains are no longer under my control as I don't have web hosting for these sites (so these subdomain sites just show a default hosting server page). Because of this, I cannot verify these in search console and submit a url/site removal request to Google. In total, there are about 70 pages from these subdomains showing up in Google at the moment and I'm concerned in case these pages have any negative impacts on my SEO. Thanks for taking the time to read my post.

Do Letters With Accents Affect SEO?
Hi Guys, My company has a franchise of a foreign company that uses an accent/foreign letter in its brand name. We have to refer to this franchise with this symbol on our website to meet their standards. I've done some research on this but its not conclusive, so i was wondering whether anyone here can confirm this for me; Will using the letter with this symbol impair our rankings for this franchise name? Obviously as a UK business people search for this franchise with a regular letter and not the accented one. I would have thought that Google is clever enough to recognise the meaning of the accented letter by now and therefore it wouldn't affect rankings (much). Furthermore, do you think that it would make any difference to use the HTML element to represent the accent rather than copy and pasting the symbol onto our website? I would've thought this would help Google pick it up, but it might not make a difference anyway! Any help is appreciated. Thanks Sam

Can a CMS affect SEO?
As the title really, I run www.specialistpaintsonline.co.uk and 6 months ago when I first got it it had bad links which google had put a penalty against it so losts it value. However the penalty was lift in Sept, the site corresponds to all guidelines and seo work has been done and constantly monitored. the issue I have is sales and visits have not gone up, we are failing fast and running on 2 or 3 sales a month isn't enough to cover any sort of cost let alone wages. hence my question can the cms have anything to do with it? Im at a loss and go grey any help or advice would be great. thanks in advance.
