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!

These are: wp-admin/admin-ajax.php showing as response code 400 and also xmlrpc.php showing as response code 405 robots.txt is as follows: user-agent: * disallow: /wp-admin/ allow: /wp-admin/admin-ajax.php Any help with what is wrong here and how to fix it would be greatly appreciated.

Will a CSS Overflow Scroll for content affect SEO rankings?
If I use a CSS overflow scroll for copy, will my SEO rankings be affected? Will Google still be able to index my copy accurately and will keywords used in the copy that are covered by the scroll be recognized by Google?

"Search Box Optimization"
A client of ours recently received en email from a random SEO "company" claiming they could increase website traffic using a technique known as "search box optimization". Essentially, they are claiming they can insert a company name into the autocomplete results on Google. Clearly, this isn't a legitimate service - however, is it a well known technique? Despite our recommendation to not move forward with it, the client is still very intrigued. Here is a video of a similar service:

Do the search engines penalise you for images being WATERMARKED?
Our site contains a library of thousands of images which we are thinking of watermarking. Does anyone know if Google penalise sites for this or is it best practice in order to protect revenues? As watermarking these images makes them less shareable (but protects revenues) i was thinking Google might then penalise us - which might affect traffic Any ideas?

Does using parentheses affect the crawlers?
Quick question: if you using a parantheses around a keyword, do search bots still recognize the keyword? Fox ex: Welcome to a website about the National Basketball Association (NBA). Will the bots recognize that I'm trying to optimize to NBA and not (NBA)? Is this different for tags vs. actual body copy?
