Images, CSS and Javascript on subdomain or external website
-
Hi guy's,
I came across webshops that put images, CSS and Javascript on different websites or subdomains. Does this boost SEO results? On our Wordpress webshop all the sourcescodes are placed after our own domainname:
www.ourdomainname.com/wp-includes/js/jquery/jquery.js?ver=1.11.3'

The only major improvement I can think of hosting images externally would be improving the overall speed of your website. If you run a pagespeed test with Google's free tool and notice your site is rendering slow then I would first consider reducing the number of javascript and css files being loaded. You will run into issues if your site is loading too many external files you can expect to see increases in bounce rates and poor engagement metrics. This may have changed but Moz did an expierement awhile back on if website speed impacts search ranking however if certain pages are taking too long to load they probably
This may have changed but Moz did an experiment awhile back on if website speed impacts search ranking. Even if speed does not directly impact rankings if certain pages are taking too long to load they probably won't be indexed.
What I would do is run Google's page speed tool on a few pages and if you have Google analytics on your site you can get some insights by looking at Behavior-> Site Speed-> Speed Suggestions and check out some of the recommendations Google is making about your site.If you have a problem with
If you find out that you have a problem with speed I came across a good article on some tips and suggestions that may be helpful for you about reducing http request.
I hope this helps some.

Images on sub domain fed from CDN
I have a client that uses a CDN to fill images, from a sub domain ( images.domain.com). We've made sure that the sub domain itself is not blocked. We've added a robots.txt file, we're creating an image sitemap file & we've verified ownership of the domain within GWT. Yet, any crawler that I use only see's the first page of the sub domain (which is .html) but none of the subsequent URL's which are all .jpeg. Is there something simple I'm missing here?

Product Images with organic results in SERP
Hey Mozzers, I've noticed that several of our product page results in Google have the product image associated with them. Today is the first day I've seen this. Does anyone know anything about these? Has Google put anything out about this? Here's a couple examples: http://content.screencast.com/users/Will_Swales/folders/Jing/media/08a16dcf-505e-443c-866d-fae6d805743e/2014-03-31_1031.png http://content.screencast.com/users/Will_Swales/folders/Jing/media/04972e7b-f6b2-4e78-ab11-95c52d69a200/2014-03-31_1056.png What's interesting is that they don't show for me when I use Chrome's Incognito mode. Any insights much appreciated! Will

No index on subdomains
Hi, We have a subdomain that is appearing in the search results - I want to hide this as it looks really bad. If I were to add the no index tag to the sub domain would URL would this affect the whole domain or just that sub domain? The main domain is vitally important - it is just that sub domain I need to hide. Many thanks

"Fourth-level" subdomains. Any negative impact compared with regular "third-level" subdomains?
Hey moz New client has a site that uses: subdomains ("third-level" stuff like location.business.com) and; "fourth-level" subdomains (location.parent.business.com) Are these fourth-level addresses at risk of being treated differently than the other subdomains? Screaming Frog, for example, doesn't return these fourth-level addresses when doing a crawl for business.com except in the External tab. But maybe I'm just configuring the crawls incorrectly. These addresses rank, but I'm worried that we're losing some link juice along the way. Any thoughts would be appreciated!

Best Way To Clean Up Unruly SubDomain?
Hi, I have several subdomains that present no real SEO value, but are being indexed. They don't earn any backlinks either. What's the best way of cleaning them up? I was thinking the following: 1. Verify them all in Webmaster Tools. 2. Remove all URLs from the index via the Removal Tool in WMT 3. Add site-wide no-index, follow directive. Also, to remove the URLs in WMT, you usually have to block the URLs via /robots.txt. If I'd like to keep Google crawling through the subdomains and remove their URLs, is there a way to do so?

Advice on Linking to an Adult Related Website
I have a question regarding whether or not Google would penalize my main website for linking to a website that has adult content. The site I am linking to is not a porn site, rather it is a site that sells web site templates for adult related stores selling sexy toys, videos, etc. For example my site that is linking to the adult related website is here: http://www.websitetemplatedesign.com/ and the link to the site is in the footer at the bottom left which is an icon. And it links to http://www.adultsextemplates.com/ Im just looking for advice as to whether or not this could be a penalty or not. I did suffer major SERP loss in the last month and Im trying to find what I am doing that may have caused this. Any advice would be appreciated.

Why is my website banned?
IMy website is Costume Machine at www.costumemachine.com . My site has been banned for 1 year now. I have requested that google reconsider my site 3 times without luck. The site is dynamic and basically pulls in feeds from affiliate sites. We have added over 1,500 pages of original content. The site has been running great since 2008 without any penalties. I don't think I got hit with any linking penalty. I cleaned up all questionable links last November when the penalty hit. Am I being hit with a "thin" site penalty? If that is the issue what is the best way to fix the problem?
