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 - topic:timeago_earlier,about a year

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.

Why Google de-rank a website.
Hi, I was inspecting a website which is covering the topic of best wheelbarrow of 2021, it is a new website and and starts ranking on google. But, after few days it got de-rank automatically and Moz is also not showing any result to that. I was wandering why this just happened and what should I do if I made my website and will not face this kind of situation?

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

Lost ranking after domain switch
I recently migrated from https://whitefusemedia.com to https://whitefuse.com. The website URL structure and content remained the same and I followed all the best practice guidance regarding checks on the new domain and appropriate 301 redirects. I have seen traffic drop by about 50% and the traffic that is still coming through is mainly coming through links still listed by Google under the old domain (https://whitefusemedia.com). Is this normal? Should I expect to see this bounce back, or is there anything I can do now to regain the rankings?

Redirect and ranking issue
Hi there - was wondering whether someone might be able to help. For a period of a day and a half, all the traffic to our website's blog articles were mistakenly being redirected to our homepage. A number of these articles ranked in the top 5 in Google worldwide for their targeted keywords, so this was a considerable amount of organic traffic that was instantly being redirected. It was a strange site glitch and our web team rectified the error, but now all these articles have disappeared from Google rankings (not visible anywhere in the first five pages). I'm presuming this must be linked to this redirect issue - we've been advised to wait and see whether Google restores these rankings, but I'm still concerned as to whether this represents a more serious problem? We have re-indexed the pages we are most concerned about, but am not sure whether there is anything else obvious we should think to do. If anyone has any thoughts, I'd be happy to hear them!

Parked domain is first in search results
We have several brand related domains which are parked and pointing to our main website. Some of these websites are redirecting using a 302 (don't ask, that's a whole other story), but these are being changed. But it shouldn't matter what type of redirect they are no? Since there has never been any traffic and they are not indexed? But it seems that one of them was indexed: exotravel.vn. A search for our brand name or the previous brand name (exotravel and exotissimo) brings up this parked domain first! How can that be? The domain has never been used and has no backlinks. exotravel.vn is redirecting and I submitted a change of address weeks ago to Google, but its still coming up first in all brand name searches for exotissimo or exotravel.

Huge ranking difference between google and bing
I am trying to rank for the keyword "trash bags" I did a lot of on-page optimization and link building. We started ranking #2 on bing and yahoo but google seems to be stubbornly fluctuating between being as high as 20 and as low as 45 and even dropped our rankings for a couple of weeks. Is there any need for concern if google is acting so different from bing/yahoo?
