No Index PDFs
-
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

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

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

Investigating a huge spike in indexed pages
I've noticed an enormous spike in pages indexed through WMT in the last week. Now I know WMT can be a bit (OK, a lot) off base in its reporting but this was pretty hard to explain. See, we're in the middle of a huge campaign against dupe content and we've put a number of measures in place to fight it. For example: Implemented a strong canonicalization effort NOINDEX'd content we know to be duplicate programatically Are currently fixing true duplicate content issues through rewriting titles, desc etc. So I was pretty surprised to see the blow-up. Any ideas as to what else might cause such a counter intuitive trend? Has anyone else see Google do something that suddenly gloms onto a bunch of phantom pages?

Pages removed from Google index?
Hi All, I had around 2,300 pages in the google index until a week ago. The index removed a load and left me with 152 submitted, 152 indexed? I have just re-submitted my sitemap and will wait to see what happens. Any idea why it has done this? I have seen a drop in my rankings since. Thanks

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

Getting a video displaying a lightbox indexed
We have created a video for a category page with the goal of building links to the page and improving the conversion rate of visitors to the page. This category is Christmas oriented so we want to get the video dropped in ASAP. Unfortunately there was a mixup with our developer and he created a lightbox pop-up to display the video on the category page. I'm concerned this will hurt our ability to get the video indexed in Google. Here was his response. Is what he says here true? "With the video originally being in lightbox the iFrame Embed was enough since the video can't be on the page, it would have to be hidden on the page which is ignored by Google. The SEO would be derived from modifying the video sitemap to define the category page as the HTML page for the Wistia video and Google will make the association. The sitemap did all the heavy lifting, the schema markup did not come till later so it had no additional affect on Google other then to re-enforce the sitemap." Thanks for your help!

Why google index my IP URL
hi guys, a question please. if site:112.65.247.14 , you can see google index our website IP address, this could duplicate with our darwinmarketing.com content pages. i am not quite sure why google index my IP pages while index domain pages, i understand this could because of backlink, internal link and etc, but i don't see obvious issues there, also i have submit request to google team to remove ip address index, but seems no luck. Please do you have any other suggestion on this? i was trying to do change of address setting in Google Webmaster Tools, but didn't allow as it said "Restricted to root level domains only", any ideas? Thank you! boson

Index forum sites
Hi Moz Team, somehow the last question i raised a few days ago not only wasnt answered up until now, it was also completely deleted and the credit was not "refunded" - obviously there was some data loss involved with your restructuring. Can you check whether you still find the last question and answer it quickly? I need the answer 🙂 Here is one more question: I bought a website that has a huge forum, loads of pages with user generated content. Overall around 500.000 Threads with 9 Million comments. The complete forum is noindex/nofollow when i bought the site, now i am thinking about what is the best way to unleash the potential. The current system is vBulletin 3.6.10. a) Shall i first do an update of vbulletin to version 4 and use the vSEO tool to make the URLs clean, more user and search engine friendly before i switch to index/follow? b) would you recommend to have the forum in the folder structure or on a subdomain? As far as i know subdomain does take lesser strenght from the TLD, however, it is safer because the subdomain is seen as a separate entity from the regular TLD. Having it in he folder makes it easiert to pass strenght from the TLD to the forum, however, it puts my TLD at risk c) Would you release all forum sites at once or section by section? I think section by section looks rather unnatural not only to search engines but also to users, however, i am afraid of blasting more than a millionpages into the index at once. d) Would you index the first page of a threat or all pages of a threat? I fear duplicate content as the different pages of the threat contain different body content but the same Title and possibly the same h1. Looking forward to hear from you soon! Best Fabian
