CDN for SEO (or not)?
-
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!

Thank you, Dirk.
I always enjoy getting explicit answers from people who I have grown to trust.
Thanks!

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).

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.

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

Are In-Page Tabs still detrimental to SEO?
Hi Mozers, Are in-page tabs still detrimental for SEO? In-page tabs: allow you to alternate between views within the same context, not to navigate to different areas. As in one long HTML page that just looks like it's divided into different pages via tabs that you can click between. Each tab has it's own URL, which I guess is for analytics tracking purposes? https://XXX https://XXX?qt-staff_profile_tabs=1 https://XXX?qt-staff_profile_tabs=2 https://XXX?qt-staff_profile_tabs=3

Lightboxes and SEO
Do lightboxes (AKA popup boxes when you click "learn more" type CTAs) have any negative effect on SEO? We are looking at revamping our sites to have more of a tiled approach, and a lightbox with summary content popping out with additional CTAs, directing to pages with more information or free trial pages. Is there any downside to this approach from an organic perspective? is there anything specific to keep in mind when creating these if not?

AJAX requests and implication for SEO
Hi, I got a question in regard to webpages being served via AJAX request as I couldn't find a definitive answer in regard to an issue we currently face: When visitors on our site select a facet on a Listing Page, the site doesn't fully reload. As a consequence only certain tags of the content (H1, description,..) are updated, while other tags like canonical URLs, meta noindex,nofollow tag, or the title tag are not updating as long as you don't refresh the page. We have no information about how this will be crawled and indexed yet but I was wondering if anyone of you knows, how this will impact SEO?

SEO value of affiliate external links
There are websites that have linked to my site. Whenever I hover over link I see my direct website URL and I am not seeing "no follow" when viewing source code so I assume these are passing link juice. However when I click on link it directs briefly to shareasale (affiliate account) in web address bar, but then quickly directs back to my website URL as directed. I was curious if these good links I am acquiring truly pass juice or since they briefly pass through an affiliate site if that cancels or dilutes the link juice. Also I am noticing when inspecting element that after the HREF it says class="external-link" I am just not sure if my link building efforts are being ruined by having an affiliate account running.I did not tell them I had one. I guess they are searching to see that I have one and trying to make a few extra commission dollars.

Advanced SEO - What would you do after you run out of keywords?
Hello! Our company has been growing in terms of traffic and ranking well for a couple of years but we are now kind of stagnating because we just don't know what to do next. We have a good blog - and with our blogs, we have been targeting all major keywords with their related keywords as a bucket. - "keyword theme / page" for a long time. But it seems we now don't have any major keyword theme to write about. What is worse is that we don't see any traffic growth since 2014 September. (although we added many good blogs) So what would do you when you run out of keywords? or keyword themes? Would you just keep pumping in more blogs and hope that you get more clicks? or at some point, you just don't care about keywords and write whatever relevant to your site? Wouldn't it hurt our site if we create similar keyword themed pages? (like regurgitating our keywords?) or even same keyword targeting pages? You must have similar experience if you are an owner of a niche site. Can you please share your experience with this kind of headaches? Thank you and look forward to your comments.

Are these URL hashtags an SEO issue?
Hi guys - I'm looking at a website which uses hashtags to reveal the relevant content So there's page intro text which stays the same... then you can click a button and the text below that changes So this is www.blablabla.com/packages is the main page - and www.blablabla.com/packages#firstpackage reveals first package text on this page - www.blablabla.com/packages#secondpackage reveals second package text on this same page - and so on. What's the best way to deal with this? My understanding is the URLs after # will not be indexed very easily/atall by Google - what is best practice in this situation?

Migrating online store to subdomain using shopify and effects on seo and energy down the road for seo
I'm looking for some clarity... Looking at using Shopify for an existing online store that we have to migrate. Setting up the store with shopify means we will be using a subdomain such as shop.mywebsite.com instead of mywebsite.com/shop. The following are points to consider when responding The client currently has an online store, however it's a proprietary shopping store and CMS that has since gone defunct and they need to migrate to an alternative in order to survive online against new CMS systems that allow the site and its content to be better optimized. There is a lot of existing SEO done on the current site that we don't want to loose PR on. There is roughly 2000 products Client has a fixed budget, dealing with checkout issues, custom work and various other "bugs" seems to be easier controlled with Shopify...thus budget can be used more on content/strategy and migration We want to run the main site in Wordpress and are wanting to use Shopify since it supports a gateway, has great features and seems like it would allow us to get more bang for the buck and can focus more on the main site and content strategy and drive traffic to the subdomain store if needed Or main concern is the effort of migrating 2000+ products to shopify and the traffic and PR it gives the current site will have a negative effect on the main domain itself. Should we really be considering this path? The domain is diveidc.com One main benefit to the subdomain is the ability to clearly segment products from the service portion of the site in the analytics and focus 2 clear strategies and track it in a very defined manner. We're really on the fence with this...any thoughts are welcome.
