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.

Google image search filter tabs and how to rank on them
I have noticed Google image search has included suggestion tabs (e.g,. design, nature... when searching background) on the top of the image search.
Technical SEO | | Mike555
Are there specific meta tags I can add into my images so that my images will show up on each tab?
Do those filters just show content based on image keywords or something else? IRme7gQ0 -
Does an Apostrophe affect searches?
Does Google differentiate between keyphrase structures such as Mens Sunglasses & Men**'**s Sunglasses? I.e. does the inclusion/exclusion of an apostrophe make any difference when optimising your main keyword/phrase for a page? Keyword explorer appears to give different results..... I.e. no data for Men's Sunglasses, but data appears for Mens sunglasses. So if I optimise my page to include the apostrophe, will it screw the potential success for that page? Thanks 🙂 Bob

Image Search
Hello Community, I have been reading and researching about image search and trying to find patterns within the results but unfortunately I could not get to a conclusion on 2 matters. Hopefully this community would have the answers I am searching for. 1) Watermarked Images (To remove or not to remove watermark from photos) I see a lot of confusion on this subject and am pretty much confused myself. Although it might be true that watermarked photos do not cause a punishment, it sure does not seem to help. At least in my industry and on a bunch of different random queries I have made, watermarked images are hard to come by on Google's images results. Usually the first results do not have any watermarks. I have read online that Google takes into account user behavior and most users prefer images with no watermark. But again, it is something "I have read online" so I don't have any proof. I would love to have further clarification and, if possible, a definite guide on how to improve my image results. 2) Multiple nested folders (Folder depth) Due to speed concerns our tech guys are using 1 image per folder and created a convoluted folder structure where the photos are actually 9 levels deep. Most of our competition and many small Wordpress blogs outrank us on Google images and on ALL INSTANCES I have checked, their photos are 3, 4 or 5 levels deep. Never inside 9 nested folders.

So... A) Should I consider removing the watermark - which is not that intrusive but is visible?
B) Should I try to simplify the folder structure for my photos? Thank you0 -
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

Sudden drop in Rankings after 301 redirect
Greetings to Moz Community. Couple of months back, I have redirected my old blog to a new URL with 301 redirect because of spammy links pointed to my old blog. I have transfer all the posts manually, changed the permalink structure and 301 redirected every individual URL. All the ranking were boosted within couple of weeks and regained the traffic. After a month I have observed, the links pointed to old site are showing up in Webmaster Tools for the new domain. I was shocked (no previous experience) and again Disavowed all links. Today, all the positions went down for new domain. My questions are: 1. Did the Disavow tool worked this time with new domain? All the links pointed to old domain were devaluated? Is this the reason for ranking drop? Or 2. 301 Old domain with Unnatural links causes the issue? 3. Removing 301 will help to regain few keyword positions? I'm taking this as a case study. Already removed the 301 redirect. Looking for solid discussion.Thanks.

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 handle (internal) search result pages?
Hi Mozers, I'm not quite sure what the best way is to handle internal search pages. In this case it's for an ecommerce website with about 8.000+ products and search pages currently look like: example.com/search.php?search=QUERY+HERE. I'm leaning towards making them follow, noindex. Since pages like this can be easily abused for duplicate content and because I'd rather have the category pages ranked. How would you handle this?

Image search and CDNs
Hi, Our site has a very high domain strength. Although our site ranks well for general search phrases, we rank poorly for image search (even though our site has very high quality images). Our images are hosted on a separate CDN with a different domain. Although there are a number of benefits to doing this, since they are on a different domain, are we not able to capitalize on our my site's domain strength? Is there any way to associate our CDN to our main site via Google webmaster tools? Has anyone researched the search ranking impacts due to storing your images on a CDN, given that your domain strength is very high? Curious on people's thoughts?
