      Our products have about 4 PDFs a piece, which really inflates our indexed pages. I was wondering if I could add REL=No Index to the PDF's URL? All of the files are on a file server, so they are embedded with links on our product pages. I know I could add a No Follow attribute, but I was wondering if any one knew if the No Index would work the same or if that is even possible. Thanks!

        The files aren't duplicate. I am familiar with using the XRobots tag. I was really just curious if my theory would work.

        Thanks for all your input.

          Hi Monica,

          I presume you already check all the options before posting this question. I have concluded this by seeing your others posts/reply in this community. 🙂

          Now here is my answer

          To prevent your PDF file (or any non HTML file) from being listed in search results, the only way is to use the HTTP X-Robots-Tag response header, e.g.:

          X-Robots-Tag: noindex

          robots.txt does not prevent your page from being listed in search results.

          What it does is stop the bot from crawling your page, but if a third party links to your PDF file from their website, your page will still be listed.

          If you stop the bot from crawling your page using robots.txt, it will not have the chance to see the X-Robots-Tag: noindex response tag. Therefore, never ever ever disallow a page in robots.txt if you employ the X-Robots-Tag header.

          I hope it helps but not very sure. 🙂

          Thanks

            1. If you want to deindex all PDF files, I recommend using the x-robots-tag in .htaccess - https://yoast.com/x-robots-tag-play/

            2. If the PDFs are pdf versions of existing pages, I would set canonicals to point to the URL you do want indexed (#2 on http://moz.com/blog/htaccess-file-snippets-for-seos )

              If the pdf's are in a separate folder on your site - you could mark that folder as noindex in robots.txt

              As far as I know, it's not possible to add a noindex to a link.

                Google not Indexing images on CDN.

                My URL is: https://bit.ly/2hWAApQ We have set up a CDN on our own domain: https://bit.ly/2KspW3C We have a main xml sitemap: https://bit.ly/2rd2jEb and https://bit.ly/2JMu7GB is one the sub sitemaps with images listed within. The image sitemap uses the CDN URLs. We verified the CDN subdomain in GWT. The robots.txt does not restrict any of the photos: https://bit.ly/2FAWJjk. Yet, GWT still reports none of our images on the CDN are indexed. I ve followed all the steps and still none of the images are being indexed. My problem seems similar to this ticket https://bit.ly/2FzUnBl but however different because we don't have a separate image sitemap but instead have listed image urls within the sitemaps itself. Can anyone help please? I will promptly respond to any queries. Thanks

                How can I get a photo album indexed by Google?

                We have a lot of photos on our website. Unfortunately most of them don't seem to be indexed by Google. We run a party website. One of the things we do, is take pictures at events and put them on the site. An event page with a photo album, can have anywhere between 100 and 750 photo's. For each foto's there is a thumbnail on the page. The thumbnails are lazy loaded by showing a placeholder and loading the picture right before it comes onscreen. There is no pagination of infinite scrolling. Thumbnails don't have an alt text. Each thumbnail links to a picture page. This page only shows the base HTML structure (menu, etc), the image and a close button. The image has a src attribute with full size image, a srcset with several sizes for responsive design and an alt text. There is no real textual content on an image page. (Note that when a user clicks on the thumbnail, the large image is loaded using JavaScript and we mimic the page change. I think it doesn't matter, but am unsure.) I'd like that full size images should be indexed by Google and found with Google image search. Thumbnails should not be indexed (or ignored). Unfortunately most pictures aren't found or their thumbnail is shown. Moz is giving telling me that all the picture pages are duplicate content (19,521 issues), as they are all the same with the exception of the image. The page title isn't the same but similar for all images of an album. Example: On the "A day at the park" event page, we have 136 pictures. A site search on "a day at the park" foto, only reveals two photo's of the albums. 3QolbbI.png QTQVxqY.jpg mwEG90S.jpg

                Z-indexed content

                I have some content on a page that I am not using any type of css hiding techniques, but I am using an image with a higher z-index in order to prevent the text from being seen until a user clicks a link to have the content scroll down. Are there any negative repercussions for doing this in regards to SEO?

                How to stop google from indexing specific sections of a page?

                I'm currently trying to find a way to stop googlebot from indexing specific areas of a page, long ago Yahoo search created this tag class=”robots-nocontent” and I'm trying to see if there is a similar manner for google or if they have adopted the same tag? Any help would be much appreciated.

                CDN Being Crawled and Indexed by Google

                I'm doing a SEO site audit, and I've discovered that the site uses a Content Delivery Network (CDN) that's being crawled and indexed by Google. There are two sub-domains from the CDN that are being crawled and indexed. A small number of organic search visitors have come through these two sub domains. So the CDN based content is out-ranking the root domain, in a small number of cases. It's a huge duplicate content issue (tens of thousands of URLs being crawled) - what's the best way to prevent the crawling and indexing of a CDN like this? Exclude via robots.txt? Additionally, the use of relative canonical tags (instead of absolute) appear to be contributing to this problem as well. As I understand it, these canonical tags are telling the SEs that each sub domain is the "home" of the content/URL. Thanks! Scott

                De-indexing millions of pages - would this work?

                Hi all, We run an e-commerce site with a catalogue of around 5 million products. Unfortunately, we have let Googlebot crawl and index tens of millions of search URLs, the majority of which are very thin of content or duplicates of other URLs. In short: we are in deep. Our bloated Google-index is hampering our real content to rank; Googlebot does not bother crawling our real content (product pages specifically) and hammers the life out of our servers. Since having Googlebot crawl and de-index tens of millions of old URLs would probably take years (?), my plan is this: 301 redirect all old SERP URLs to a new SERP URL. If new URL should not be indexed, add meta robots noindex tag on new URL. When it is evident that Google has indexed most "high quality" new URLs, robots.txt disallow crawling of old SERP URLs. Then directory style remove all old SERP URLs in GWT URL Removal Tool This would be an example of an old URL:
                www.site.com/cgi-bin/weirdapplicationname.cgi?word=bmw&what=1.2&how=2 This would be an example of a new URL:
                www.site.com/search?q=bmw&category=cars&color=blue I have to specific questions: Would Google both de-index the old URL and not index the new URL after 301 redirecting the old URL to the new URL (which is noindexed) as described in point 2 above? What risks are associated with removing tens of millions of URLs directory style in GWT URL Removal Tool? I have done this before but then I removed "only" some useless 50 000 "add to cart"-URLs.Google says themselves that you should not remove duplicate/thin content this way and that using this tool tools this way "may cause problems for your site". And yes, these tens of millions of SERP URLs is a result of a faceted navigation/search function let loose all to long.
                And no, we cannot wait for Googlebot to crawl all these millions of URLs in order to discover the 301. By then we would be out of business. Best regards,
                TalkInThePark
