      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?

                          Same URL for languages sub-directories

                          Hi All, I have a main domain and 9 different subdirectories for languages,  example: www.example.com/page.html www.example.com/uk/page-uk.html www.example.com/es/page-es.html we are implementing hreflang tags for the languages, but we are thinking to get rid of the dashes on the languages URL: -uk or -es, so it will be: www.example.com/page.html www.example.com/uk/page.html www.example.com/es/page.hrml would this be a problem? to have same page names even if they are in different subdirectories? would we need to add canonical tags, at lease for the main domain URLs? www.kornferry.com/page.html Thank you, Rachel

                          Redirect multiple domains to 1 domain or not?

                          Hi there, I have client who has multiple domains that already have some PA and DA. Problem is that most websites have the same content and rank better on different keywords.
                          I want to redirect all the websites to 1 domain because it’s easier to manage and it removes any duplicate content. Question is if I redirect domain x to domain y do the rankings of domain x increase on domain y? Or is it better to keep domain x separately to generate more referral traffic to domain y? Thanks in advance! Cheers

                          Spammers created bad links to old hacked domain, now redirected to our new domain. Advice?

                          My client had an old site hacked (let's call it "myolddomain.com") and the hackers created many links in other hacked sites with links such as http://myolddomain.com/styless.asp?jordan-12-taxi-kids-cheap-T8927.html The old myolddomain.com site was redirected to a different new site since then, but we still see over a thousand spam links showing up in the new site's Search Console 404 crawl errors report. Also, using the links: operator in google search, we see many results of spam links. Should we be worried about these bad links pointing to our old site and redirecting to 404s on the new site? What is the best recommendation to clean them up? Ignore? 410s? Other? I'm seeing conflicting advice out there. The old site is hosted by the client's previous web developer who doesn't want to clean anything up on their end without an ongoing hosting contract. So beyond turning redirects on or off, the client doesn't want to pay for any additional hosting. So we don't have much control over anything related to "myolddomain.com". 😞 Thanks in advance for any assistance!

                          Are images stored in Amazon S3 buckets indexable to your domain?

                          We're storing all our images in S3 bucket, common practice, but we want to get these images to drive traffic back to our site -- and credit for that traffic. We've configured the URLs to be s3.owler.com/<image_name>/<image_id>. I've not seen any of these images show in our web master tools. I am wondering if we're actually not going to get the credit for these images because technically they do sit on another domain. </image_id></image_name>

                          I have a eCommerce site and the site structure is domain/product-name rather than domain/product-category/product-name Do you think this will have a negative impact SEO Wise? I have seen that some of my individual product pages do get better rankings than my categories.

                          We're launching a blog on a sub-domain of a corp site (blog.corpsite.com). We already have corpsite.com set up in the Search Console. Should I set up a separate property for this sub-domain in the Search Console (WMT) in order to manage it? Is it necessary? Thanks, JM

                          Image search and CDNs

                          Hi, Our site has a very high domain strength.  Although our site ranks well for general search phrases, we rank poorly for image search (even though our site has very high quality images). Our images are hosted on a separate CDN with a different domain.  Although there are a number of benefits to doing this, since they are on a different domain, are we not able to capitalize on our my site's domain strength?  Is there any way to associate our CDN to our main site via Google webmaster tools?  Has anyone researched the search ranking impacts due to storing your images on a CDN, given that your domain strength is very high? Curious on people's thoughts?
