      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.jpg

      Examples of other website:

      Website 1:
      https://www.zalando.nl/heren-home/

      Sourcecode:
      https://secure-i3.ztat.net//camp/03/d5/1a0168ac81f2ffb010803d108221.jpg
      https://secure-media.ztat.net/media/cms/adproduct/ad-product.min.css?_=1447764579000

        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.

          Hidden H1 Tag on Image

          Hi, In the page I'm working on, I encountered an tag in an image, rather than in a text form. Do you think it's an issue when it comes to SEO?
          What do you suggest I should do if there is an issue? Keen to hear from you!

          I have multiple URLs that redirect to the same website. Is this an issue?

          I have multiple URLs that all lead to the same website. Years ago they were purchased and were sitting dormant. Currently they are 301 redirects and each of the URLs feed to different areas of my website. Should I be worried about losing authority? And if so, is there a better way to do this?

          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?

          Does a subdomain benefit from being on a high authority domain?

          I think the title sums up the question, but does a new subdomain get any ranking benefits from being on a pre-existing high authority domain. Or does the new subdomain have to fend for itself in the SERPs?

          Replace Header Text With Image

          I have a static website that I would like to retheme. I have the mockup, and its spliced. The website holds nice rankings right now, and I want to keep them in place. The one thing that will change with this new design is the header will no longer be text, but instead an image.  Is there a way to ensure googlebot still sees the H1 tag header exactly how it is now but use an image for the header instead? I dont want any blackhat tricks that will get me banned. Just wondering if there is a simple way to have googlebot see the header as text (not ALT img txt) so the site does not appear to have changed at all. (It hasnt, I only am changing the graphics and colors of background, and header image for better branding.

          How to move my blog from subdomain to subfolder?

          Not an unusual situation, I have a blog on blog.domain.com it has quite a few blog postings.  The platform is old and will be scrapped, but the blog content itself is going to be moved to domain.com/blog. The current process is we are manually listing all linked to/content pages and we are going to 301 redirect them to their counterparts on the new blog.  This is going to be a tedious process. A) Is there any way to automate the moving of the blog? B) What is the best way to do the massive 301 redirect, php headers, .htaccess?  Should we move the individual pages with redirects, or redirect the domain in the .htaccess (this will be very difficult to match all the titles and file structure)?
