      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

              Using the same image across the site?

              Hi just wondering i'm using the same image across 20 pages which are optimized for SEO purposes. I was wondering is there issues with this from SEO standpoint? Will Google devalue the page because the same image is being used? Cheers.

              Help with facet URLs in Magento

              Hi Guys, Wondering if I can get some technical help here... We have our site britishbraces.co.uk , built in Magento. As per eCommerce sites, we have paginated pages throughout. These have rel=next/prev implemented but not correctly ( as it is not in is it in ) - this fix is in process. Our canonicals are currently incorrect as far as I believe, as even when content is filtered, the canonical takes you back to the first page URL. For example, http://www.britishbraces.co.uk/braces/x-style.html?ajaxcatalog=true&brand=380&max=51.19&min=31.19 Canonical to... http://www.britishbraces.co.uk/braces/x-style.html Which I understand to be incorrect. As I want the coloured filtered pages to be indexed ( due to search volume for colour related queries ), but I don't want the price filtered pages to be indexed - I am unsure how to implement the solution? As I understand, because rel=next/prev implemented ( with no View All page ), the rel=canonical is not necessary as Google understands page 1 is the first page in the series. Therefore, once a user has filtered by colour, there should then be a canonical pointing to the coloured filter URL? ( e.g. /product/black ) But when a user filters by price, there should be noindex on those URLs ? Or can this be blocked in robots.txt prior? My head is a little confused here and I know we have an issue because our amount of indexed pages is increasing day by day but to no solution of the facet urls. Can anybody help - apologies in advance if I have confused the matter. Thanks

              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.

              URL Rewriting Best Practices

              Hey Moz! I’m getting ready to implement URL rewrites on my website to improve site structure/URL readability. More specifically I want to: Improve our website structure by removing redundant directories. Replace underscores with dashes and remove file extensions for our URLs. Please see my example below: Old structure: http://www.widgets.com/widgets/commercial-widgets/small_blue_widget.htm New structure: https://www.widgets.com/commercial-widgets/small-blue-widget I've read several URL rewriting guides online, all of which seem to provide similar but overall different methods to do this. I'm looking for what's considered best practices to implement these rewrites. From what I understand, the most common method is to implement rewrites in our .htaccess file using mod_rewrite (which will find the old URLs and rewrite them according to the rewrites I implement). One question I can't seem to find a definitive answer to is when I implement the rewrite to remove file extensions/replace underscores with dashes in our URLs, do the webpage file names need to be edited to the new format? From what I understand the webpage file names must remain the same for the rewrites in the .htaccess to work. However, our internal links (including canonical links) must be changed to the new URL format. Can anyone shed light on this? Also, I'm aware that implementing URL rewriting improperly could negatively affect our SERP rankings. If I redirect our old website directory structure to our new structure using this rewrite, are my bases covered in regards to having the proper 301 redirects in place to not affect our rankings negatively? Please offer any advice/reliable guides to handle this properly. Thanks in advance!

              Image URLs - best practice

              Hi - I'm assuming image URL best practice follows same principles as non image URLs (not too many files and so on) - I notice alot of web devs putting photos in subdomains, so wonder if I'm missing something (I usually avoid subdomains like the plague)!

              Switching site from non-www to www

              Howdy folks, I've got a website that is roughly 3 months old. I created it as a naked URL as I often prefer the look but I've noticed that a lot of my competition has www and also some of my clients seem to prefer it as well. I feel like switching it to www will be of long-term benefit for my site. The problem is that I currently have several pages with first page rankings and a backlinks. I am wondering what the negative effects of switching it to www would be, and how I can minimize any issues. I am guessing I should do a redirect, and I have access to some of the backlinks so I can change those as well, but is there anything else? Thoughts? I appreciate the feedback!

              Would changing the file name of an image (not the alt attribute) have an effect of on seo / ranking of that image and thus the site?

              Would changing the file name of image, not the alt attribute nor the image itself (so it would be exactly the same but just a name change) have any effect on : a) A sites seo ranking b) the individual images seo ranking (although i guess if b) would be true it would have an effect on a) although potentially small.) This is the sort of change i would be thinking of making : ![Red ford truck](2554.jpg) changed to ![Red ford truck](6842.jpg)

              301 Redirection and apostrophes in URLs

              Hi I am experiencing trouble getting any redirects with apostrophes in the URLs to 301 redirect in order to eliminate 404 errors. I have tried replacing the instance of the apostrophe in the source URL field to %27 and variations of this but to no avail. The site is a wordpress site (the old URLS are legacies from the old Business Catalyst site) and I am using the redirection plug in. I have gone into some detail with a helpful soul here http://wordpress.org/support/topic/how-to-deal-with-apostrophes-in-source-url but unfortunately to no result. If anyone has any idea how to solve this puzzle I would be grateful for the help.
