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!

Hide sitelinks from Google search results
Does anyone have any recommendations on how you can tell Google (hopefully via a URL) not to index that page of a website? I have tried through SEO Yoast to hide certain sitemaps (which has worked to a degree) but certain functionalities of Wordpress websites show links without them actually being part of a "sitemap" so those links are harder to hide. I'm having an issue with one of my websites - the sitelinks that Google is suggesting are nowhere near the most popular pages and I know that you can't make recommendations through Google not to show certain pages through Search Console. anymore. Any suggestions are greatly appreciated! Thanks!

Wordpress versus html and google ranking
My current SEO has always recommended that I take my site to wordpress. I really don't want to move to wordpress. I don't like it... I just like writing code in raw html, css, and script. I feel like I have more control that way. Wordpress just seems like a platform for blogs (I have my blog in wordpress). My question is, do wordpress websites typically rank better? Is there benefit to moving to it?

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

How to Resolve Rankings Drop from a DDOS Attack?
Our rankings just plummeted on Tuesday across the board. There was a DDOS attack on Tuesday and since then the rankings went down and have stayed down, even though the DDOS attack has been resolved. Also, this is the 3rd or 4th attack they've encountered this year. How long could this last? How can we deal with this? Thanks
