          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?

            Alphonse it sounded like they were just waiting for the sitemap to launch. Other than that, I couldn't think of anything else to add because the sitemap should solve their issue. However, I have marked this as "Discussion" again.

                We have the same issue however we have image XML sitemaps on each country subdomain's XML Index which point to the image files on images.domain.com.

                Example:

                https://uk.domain.com/image-sitemap1.xml

                https://us.domain.com/image-sitemap1.xml

                These 2 files are the same.

                We also don't have a homepage on images.domain.com and it currently responds with a 404.

                Do you think we need to create a landing page on the homepage and host the image XML sitemap at https://images.domain.com/images-sitemap1.xml rather than in each sub-domain?

                Thanks.

                  Yes, we are doing everything correctly, aside from waiting for IT department to create a sitemap.

                    Are you using your own subdomain or one somewhere else (e.g. akamai.com)? You should use your own subdomain, if possible.

                    Was this a change from a previous version that didn't use a CDN? If those images were/are hosted on your primary domain be sure to match the filenames and paths as closely as possible to what they were before.

                    If you're doing that you shouldn't have a problem once the sitemap is submitted.

                    For more information please check out this post:
                    http://www.goinflow.com/four-seo-best-practices-for-using-a-content-delivery-network-cdn/

                    How do you know that Google only attempts to crawl the primary domain URL (i.e. the .html page)? Are you checking log files?

                    Is the crawler you're using set to crawl external URLs? If not, that could be the issue. Technically a subdomain is a totally separate website so most tools don't crawl them by default.

                      We've correctly applied the CNAME directive from the CDN to reflect the subdomain. Yet, when Google or any other tool attempts to crawl it only shows ONE URL. Not the images that are residing on their own independent URL's.

                        In order to put those image URLs for the crawler to be able to access them you should either:

                        • Link to the URLs of the images (does that .html page in the subdomain contain these URLs?)

                        or

                        • Use the images URLs as resources in the pages already been crawled. Unfortunately this could be tricky when dealing with CDNs since those resources are dynamic.

                        In either case, the sitemap will solve your problem.

                          The sitemap is not completed yet. Server logs show Googlebot only indexing one page the .html page, not other pages.

                            Did you reference the sitemap in the robots.txt file or did you set up it in GWT?

                              Cross Canonicalization for domains with same menu

                              sharing menu items

                              I have a client who took 3 pages from its main website and made them into their own domains. So that now, for example,
                              www.mainsite.com/page
                              redirects to
                              www.page.com This is so users can be given access to the content on that specific page with ease.
                              Now, www.page.com has the same menu items as www.mainsite.com, so that users who select the menu items on www.page.com will be circled back to the main site. But this means that there are now different URLs for these pages.
                              ie:
                              On www.mainsite.com there is: www.mainsite.com/menu-item
                              (the content resides here) And on www.page.com there is: www.page.com/menu-item
                              (Which is basically "scaffolding" to support the page and a means to get around, so to speak.This is to make any and all pages accessible at either domain. ) I have only seen this type of URL on the Moz campaign crawl. In the real world, when a user selects a menu item from the www.page.com, it will circle back to www.mainsite.com/menu-item SEO-wise, should I use cross-canonicalization to point www.page.com/menu-item to www.mainsite.com/menu-item? Or would this be splitting hairs since these are only seen on the Moz crawl?

                              Does having a sub-domain on a different server affect SEO?

                              I'm working with a company that has a hard-coded website on the root domain, and then a WordPress blog on a subdomain on a separate server. We're planning on implementing a hub and spoke model for their content, hosting the main hubs on the root domain and the linked articles on the blog. Is having the blog on a different server going to hinder our SEO efforts?

                              Lost ranking after domain switch

                              I recently migrated from https://whitefusemedia.com to https://whitefuse.com. The website URL structure and content remained the same and I followed all the best practice guidance regarding checks on the new domain and appropriate 301 redirects. I have seen traffic drop by about 50% and the traffic that is still coming through is mainly coming through links still listed by Google under the old domain (https://whitefusemedia.com). Is this normal? Should I expect to see this bounce back, or is there anything I can do now to regain the rankings?

                              Not all images indexed in Google

                              Hi all, Recently, got an unusual issue with images in Google index. We have more than 1,500 images in our sitemap, but according to Search Console only 273 of those are indexed. If I check Google image search directly, I find more images in index, but still not all of them. For example this post has 28 images and only 17 are indexed in Google image. This is happening to other posts as well. Checked all possible reasons (missing alt, image as background, file size, fetch and render in Search Console), but none of these are relevant in our case. So, everything looks fine, but not all images are in index. Any ideas on this issue? Your feedback is much appreciated, thanks

                              Rel canonical between mirrored domains

                              Hi all & happy new near! I'm new to SEO and could do with a spot of advice: I have a site that has several domains that mirror it (not good, I know...)  So www.site.com, www.site.edu.sg, www.othersite.com all serve up the same content.  I was planning to use rel="canonical" to avoid the duplication but I have a concern: Currently several of these mirrors rank - one, the .com ranks #1 on local google search for some useful keywords. the .edu.sg also shows up as #9 for a dirrerent page. In some cases I have multiple mirrors showing up on a specific serp. I would LIKE to rel canonical everything to the local edu.sg domain since this is most representative of the fact that the site is for a school in Singapore but...
                              -The .com is listed in DMOZ (this used to be important) and none of the volunteers there ever respoded to requests to update it to the .edu.sg
                              -The .com ranks higher than the com.sg page for non-local search so I am guessing google has some kind of algorithm to mark down obviosly local domains in other geographic locations Any opinions on this? Should I rel canonical the .com to the .edu.sg or vice versa? I appreciate any advice or opinion before I pull the trigger and end up shooting myself in the foot! Best regards from Singapore!

                              Umlaut in domain

                              Hi, My client wants to expand it's business to Germany and logically we need a domain name to match. We've found a great one and regsiterd several variants to it. However I just found out that in Germany it is possible (while here it's not) to register a domain with an umlaut. My question is: will google assign more value to: schädlinge.de than schadlinge.de when users search for schädlinge? If yes, how large will the difference be? (I will use an umlaut in the title etc) Kind regards,
                              Jason.

                              I feel kind of stupid asking this, but if i use one it would speed things up quite a bit. It is for a ecommerce website, any guidance on this would be awesome!

This client has a few other websites that are divisions of their company. However these divisions/websites are no longer used. They are wanting to delete the websites but redirect the domains to their name main website. They believe this will pass on SEO benefits as these old division sites are old and have a good PR and history. I'm unsure for DEFINITE, which way is correct?
