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'
www.ourdomainname.com/wp-content/uploads/2015/09/example.jpgExamples of other website:

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.

Dynamically Inserting Noindex With Javascript
Hello, I have a broken plugin creating hundreds of WP-Content directory pages being indexed by Google. I can not access the source code of these pages to add a noindex to them. The page URL's all have the plugin name within them. In order to resolve the issue, I wrote a solution with javascript to dynamically add in a noindex tag to any URL containing the plugin name. Would this noindex be respected by Google and is there a way to immediately check that it is respected? Currently, I can not delete the plugin due to issues with it's php. If you would like to view the code: https://codepen.io/trodrick/pen/Gwwaej?editors=0010 Thanks!

Is SEO effected of putting an external link in the primary navigation of a website?
I have a customer, www.xxx.com. This site has good traffic, low bounce rate (28%), 2:00 min avg time on site, and 45% return visitor rating. No spam rankings, etc. Good load time. Another site, www.yyy.com, has sent out a request for them to add them as a new link in www.xxx.com's primary navigation - using a title such as "abc" (not the name of the company or site of yyy.com). This second site, www.yyy.com, has a bounce rate of 98%, avg time on site is :30, and 10.2% return visitor rate. No spam flags noted in Open Site explorer. Plus they are asking other sites similar to www.xxx.com to do the same thing. Questions/Concerns and Feedback appreciated: Will yyy.com's analytics and quality pass back to xxx.com and cause Google or algorithms to flag or penalize xxx.com? (It ranks #1 for quite a few things.) The relevancy between the sites is good -same industry, same business objectives. From a usability standpoint, isn't it more appropriate to place a link to another website in a different way? e.g. a promotional graphic wit a link or anchor text links? Isn't it more appropriate to ask another business for links - not using the primary nav of a site? (It seems yyy.com is essentially asking other sites for 'free advertising/promotion.' Thanks!

JavaScript page loader - SEO impact
Hello all,
Technical SEO | | Lvet
I am working on a site that has a bizarre page load system. All pages get loaded trough the same Javascript snippet, for example: Changing the values in the form changes the page that is loaded. The most incredible thing is that, against my expectations, pages do get indexed by Google.
My question is: "Does loading pages dynamically using JavaScript affect the overall SEO performance?" Why are pages getting indexed? Thank you for shedding light on this.
Cheers

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

For an image which is in the CSS and not the HTML, can you add an alt tag?
I would like to improve SEO on a page with three big images, which are currently hosted in the CSS. The sample I am working with is at http://xquisitevents.com/about-us/ and I put my cursor over the big picture of the wedding dress with bouquet, I inspected the element and saw this code in a div tag: #upperleft { background-image:url(images/AboutTopLeft.jpg); Can I add an alt tag to the CSS somehow, or can I have it added to the HTML? What is the best way to handle this, to include keywords like exquisite weddings and special event designs?

Exact match subdomains
Hi, I have seen significant SEO benefits from owning exact match domains and was wondering whether exact match subdomains hold the same (or some) of these benefits? eg. halloweencostumes.co.uk vs. halloween [dot] costumes.co.uk Many thanks.
