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.

CSS background image links bad for seo?
On one of the websites I manage SEO for, the developers are changing how our graphical links are coded. They're basically coding in such away where there is no anchor text and no alt tag, so for example: So there's no anchor nor alt context for Google's crawler. How badly will this affect SEO, or is it extremely minimal and I shouldn't worry about? Thanks in advance.

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

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?

Websites being hacked & duplicated, what should we do?
Hi, please help! Our website was hacked and being totally duplicated. They even injected codes to intercept our orders. Although the codes issue had been solved, still there're two mirror sites out there. When search for some of our key words, they even have good ranks. What exactly can we do to let Google ban those two sites. Thanks in advance!

Microsite on subdomain vs. subdirectory
Based on this post from 2009, it's recommended in most situations to set up a microsite as a subdirectory as opposed to a subdomain. http://www.seomoz.org/blog/understanding-root-domains-subdomains-vs-subfolders-microsites. The primary argument seems to be that the search engines view the subdomain as a separate entity from the domain and therefore, the subdomain doesn't benefit from any of the trust rank, quality scores, etc. Rand made a comment that seemed like the subdomain could SOMETIMES inherit some of these factors, but didn't expound on those instances. What determines whether the search engine will view your subdomain hosted microsite as part of the main domain vs. a completely separate site? I read it has to do with the interlinking between the two.
