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.

Removing a site from Google index with no index met tags
Hi there! I wanted to remove a duplicated site from the google index. I've read that you can do this by removing the URL from Google Search console and, although I can't find it in Google Search console, Google keeps on showing the site on SERPs. So I wanted to add a "no index" meta tag to the code of the site however I've only found out how to do this for individual pages, can you do the same for a entire site? How can I do it? Thank you for your help in advance! L

Homepage not indexed - seems to defy explanation
Hey folks Hoping to get some more eyes on a specific problem I am seeing with a clients site. Site: http:www.ukjuicers.com We have checked everything we can think of and the usual suspects here are not present: Canonical URL is in place Site is shown as indexed in search console No Crawl, DNS, Connectivity or server errors No robots.txt blocking - verified in search console No robots meta tags or directives Fetch as Google works Fetch & render works site command returns all other pages info command does not return the homepage homepage is cached and cache has been updated since this issue started: http://webcache.googleusercontent.com/search?q=cache:www.ukjuicers.com homepage is indexed in yahoo and Bing all variations redirect to the www.ukjuicers.com domain (.co.uk, .com, www, sans www etc) The only issue I found after some extensive digging was some issues with the HTTP and HTTPS versions of the site both being available and both specifying the canonical version as themselves. So, http site used canonicals with http and https site used canonicals with https. So, a conflict there with the canonical exacerbating the problem it is there to solve. The HTTPS site is not indexed though and we have set this up in webmaster tools and now the web developer has set redirects to ensure all versions even the https now 301 redirect to the http://www.ukjuicers.com page so these canonical issues have been ironed out. But... it's still not indexing the homepage. The practical implications of this are quite scary - the site used to be somewhere between 1st and 4th for keywords like 'juicers', 'juicer' etc. Now they are bottom of page 1 or top of page 2 with an internal page. They were jostling with the big boys (amazon, argos, john lewis etc) but now they are right at the bottom of the second page. It's a strange one - i have seen all manor of technical problems over the years but this one seems to defy sensible explanation. The next step is to do a full technical SEO audit of the site but I am always of the opinion that with many eyes all bugs are shallow so if anyone has any input or experience with odd indexation problems like this would love to get your input. Cheers

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.

How to determine which pages are not indexed
Is there a way to determine which pages of a website are not being indexed by the search engines? I know Google Webmasters has a sitemap area where it tells you how many urls have been submitted and how many are indexed out of those submitted. However, it doesn't necessarily show which urls aren't being indexed.

What to do with 302 redirects being indexed
Hi there, Our site's forums include permalinks that for some reason uses an intermediary URL that 302 redirects to the URL with the permalink anchor. For example: http://en.tradimo.com/learn/chart-analysis/time-frames/ In the comments, there is a permalink to the following URL; en.tradimo.com/co/50c450005f2b949e3200001b/ Â (there is no content here, and never has been). Â This URL 302 redirects to the following final URL: http://en.tradimo.com/learn/chart-analysis/time-frames/?offset=0&limit=20#50c450005f2b949e3200001b The problem is, Google is indexing the redirect URL (en.tradimo.com/co/50c450005f2b949e3200001b/) and showing duplicate content even though we are using the nofollow tag on these links. Ideally, we would directly use the last link rather than redirecting. Â Alternatively, I'd say a 301 redirect would be preferable. Â But if both aren't available, is there a way to get these pages out of the index? Is the canonical tag the best way? Â I really wish I could just add /co/ to the robots.txt file, but I think they would still be in the index, right? Thanks for your help!

Google is indexing my directories
I'm sure this has been asked before, but I was looking at all of Google's results for my site and I found dozens of results for directories such as: Index of /scouting/blog/wp-includes/js/swfupload/plugins Obviously I don't want those indexed. How do I prevent Google from indexing those? Also, it only seems to be doing it with Wordpress, not any of the directories on my main site. (We have a wordpress blog, which is only a portion of the site)

Instant Indexing
I've been  working on a site for a while now, methodically building content and building trust and authority. Lately I've noticed that anything I publish there appears to be instantly indexed by Google, which surprises me. I haven't had this happen before so I'm curious. I'd be interested to hear the experience of others.
