      I see this strangely formatted image URLs on websites time and again - is this an issue - I imagine it isn't best practice but does it make any difference to SEO?

      Thanks in advance, Luke

        It's not best practice for sure, and it doesn't help with SEO (ideally, you want clean, clear, descriptive URLs and paths). That said, if Google can index the content of the page (or the image), it's not a dealbreaker. You can check by using the URL/image path in Google Images e.g. this one.

          Hi Andy - yes, just capitals and non-standard characters in the URLs (bad practice, basically, for URLs) - I don't think an example will help beyond what I've told you - hope that's OK, Luke

              Google not Indexing images on CDN.

              My URL is: http://bit.ly/1H2TArH We have set up a CDN on our own domain: http://bit.ly/292GkZC  We have an image sitemap: http://bit.ly/29ca5s3 The image sitemap uses the CDN URLs. We verified the CDN subdomain in GWT. The robots.txt does not restrict any of the photos: http://bit.ly/29eNSXv. We used to have a disallow to /thumb/ which had a 301 redirect to our CDN but we removed both the disallow in the robots.txt as well as the 301. Yet, GWT still reports none of our images on the CDN are indexed. The above screenshot is from the GWT of our main domain.The GWT from the CDN subdomain just shows 0. We did not submit a sitemap to the verified subdomain property because we already have a sitemap submitted to the property on the main domain name. While making a search of images indexed from our CDN, nothing comes up: http://bit.ly/293ZbC1While checking the GWT of the CDN subdomain, I have been getting crawling errors, mainly 500 level errors. Not that many in comparison to the number of images and traffic that we get on our website. Google is crawling, but it seems like it just doesn't index the pictures!? Can anyone help? I have followed all the information that I was able to find on the web but yet, our images on the CDN still can't seem to get indexed.

              Does rewriting a URL affect the page authority?

              Hi all, I recently optimized an overview page for a car rental website. Because the page didn’t rank very well, I rewrote the URL, putting the exact keyword combination in it. Then I asked Google to re-crawl the URL through Search Console. This afternoon, I checked Open Site Explorer and saw that the Page Authority had decreased to 1, while the subpages still have an authority of about 18-20. Hence my question: is rewriting a URL a bad idea for SEO? Thank you,
              Lise

              If Robots.txt have blocked an Image (Image URL) but the other page which can be indexed has this image, how is the image treated?

              Hi MOZers, This probably is a dumb question but I have a case where the robots.tags has an image url blocked but this image is used on a page (lets call it Page A) which can be indexed. If the image on Page A has an Alt tags, then how is this information digested by crawlers? A) would Google totally ignore the image and the ALT tags information? OR B) Google would consider the ALT tags information? I am asking this because all the images on the website are blocked by robots.txt at the moment but I would really like website crawlers to crawl the alt tags information. Chances are that I will ask the webmaster to allow indexing of images too but I would like to understand what's happening currently. Looking forward to all your responses 🙂 Malika

              Should I redirect images when I migrate my site

              We are about to migrate a large website with a fair few images (20,000). At the moment we include images in the sitemap.xml so they are indexed by Google and drive traffic (not sure how I can find out how much though). Current image slugs are like:
              http://website.com/assets/images/a2/65680/thumbnails/638x425-crop.jpg?1402460458 Like on the old site, images on the new website will also have unreadable cache slugs, like:
              http://website.com/site_media/media/cache/ce/7a/ce7aeffb1e5bdfc8d4288885c52de8e3.jpg All content pages on the new site will have the same slugs as on the old site. Should I go through the trouble of redirecting all these images?

              Weird 404 URL Problem - domain name being placed at end of urls

              Hey there. For some reason when doing crawl tests I'm finding pages with the domain name being tacked on the end and causing 404 errors. 
              For example:  http://domainname.com/page-name/http://domainname.com This is happening to all pages, posts and even category type 1. Site is in Wordpress
              2. Using Yoast SEO plugin Any suggestions? Thanks!

              Best way to noindex an image?

              Hi all, A client wanted a few pages noindexed, which was no problem using the meta robots noindex tag. However they now want associated images removed, some of which still appear on pages that they still want indexed. I added the images to their robots.txt file a few weeks ago (probably over a month ago actually) but they're all still showing when you do an image search. What's the best way to noindex them for good, and how do I go about implementing it? Many thanks, Steve

              Multiple URLs for the same page

              I am working with a client and recently discovered that they have several URLs that go to the same page. http://www.maps.com/FunFacts.aspx

              http://www.maps.com/FunFacts
              http://www.maps.com/funfacts.aspx?.nav=FF I am afraid this is happening all over the site. So, my question is: Is this hurting the SEO and how? If so what is the best way to go about fixing this problem? Thanks for your help!
