      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:

        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.

          Moving E-Commerce Store to Subdomain?

          Hi all, We have a customer who currently uses Square for their in-store point-of-sale system as well as for their e-commerce website. From my understanding, a Square site is a watered-down version of Weebly, and is proving to be highly restrictive from an SEO and content structuring standpoint. It's been an uphill battle to try and get traction for their site in SERPs. Would it be a bad idea to move the entire Square online store to a subdomain, and install WordPress on the root domain? This way their online store would remain as-is, but the primary pages on the site would be on WordPress which would give us a lot more control over the content. I just want to make sure this doesn't negatively impact their SEO. Thanks!

          Can an external firewall affect rankings?

          For security reasons we are now routing traffic through an external firewall cum CDN. Our server and domain IPs remain the same, but any request is routed through an external IP, which then forwards the traffic. Would our rankings be affected because of IP changes? Thanks Sam

          Subdomain 403 error

          Hi Everyone, A crawler from our SEO tool detects a 403 error from a link from our main domain to a a couple of subdomains. However, these subdomains are perfect accessibly. What could be the problem? Is this error caused by the server, the crawlbot or something else? I would love to hear your thoughts.

          Measuring the size of a competitors website?

          I think our website is too big, far too many indexed pages. I'd like to do some research on how big our competitors' websites are (how many indexed pages). Is there a way to do this? Cheers, Rhys

          Image Search

          Hello Community, I have been reading and researching about image search and trying to find patterns within the results but unfortunately I could not get to a conclusion on 2 matters. Hopefully this community would have the answers I am searching for. 1) Watermarked Images (To remove or not to remove watermark from photos) I see a lot of confusion on this subject and am pretty much confused myself. Although it might be true that watermarked photos do not cause a punishment, it sure does not seem to help. At least in my industry and on a bunch of different random queries I have made, watermarked images are hard to come by on Google's images results. Usually the first results do not have any watermarks. I have read online that Google takes into account user behavior and most users prefer images with no watermark. But again, it is something "I have read online" so I don't have any proof.  I would love to have further clarification and, if possible, a definite guide on how to improve my image results. 2)  Multiple nested folders (Folder depth) Due to speed concerns our tech guys are using 1 image per folder and created a convoluted folder structure where the photos are actually 9 levels deep. Most of our competition and many small Wordpress blogs outrank us on Google images and on ALL INSTANCES I have checked, their photos are 3, 4 or 5 levels deep. Never inside 9 nested folders.  
          So... A) Should I consider removing the watermark - which is not that intrusive but is visible?
          B) Should I try to simplify the folder structure for my photos? Thank you

          Should we move our documentation off subdomain?

          Background: We have a popular open source e-commerce platform at http://spreecommerce.com.  Right now the documentation is on http://guides.spreecommerce.com.  We have "edge" documentation (for stuff that's not yet released) on http://edgeguides.spreecommerce.com but since it's largely duplicative we've told google not to index any of the edge stuff (via robots.txt). Question: Should we consider moving the guides under the main website under /docs or something like this?  There's a ton of great content that people often read to learn more about the platform.  Seems like we might be diluting our juice a bit to have it on a separate domain.  WDYT?

          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?
