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.

Does Google index internal anchors as separate pages?
Hi, Back in September, I added a function that sets an anchor on each subheading (h[2-6]) and creates a Table of content that links to each of those anchors. These anchors did show up in the SERPs as JumpTo Links. Fine. Back then I also changed the canonicals to a slightly different structur and meanwhile there was some massive increase in the number of indexed pages - WAY over the top - which has since been fixed by removing (410) a complete section of the site. However ... there are still ~34.000 pages indexed to what really are more like 4.000 plus (all properly canonicalised). Naturally I am wondering, what google thinks it is indexing. The number is just way of and quite inexplainable. So I was wondering: Does Google save JumpTo links as unique pages? Also, does anybody know any method of actually getting all the pages in the google index? (Not actually existing sites via Screaming Frog etc, but actual pages in the index - all methods I found sadly do not work.) Finally: Does somebody have any other explanation for the incongruency in indexed vs. actual pages? Thanks for your replies! Nico

No index on subdomains
Hi, We have a subdomain that is appearing in the search results - I want to hide this as it looks really bad. If I were to add the no index tag to the sub domain would URL would this affect the whole domain or just that sub domain? The main domain is vitally important - it is just that sub domain I need to hide. Many thanks

Question on noscript tags and indexing
If I have a <noscript>tag on every page of my website with the same sentence over and over saying something to the effect of "Sorry our site uses Javascript, please enable javascript for the full site experience.", Webmaster Tools will tell me that one of the most common words on my site is "Javascript".</p> <p>Is this something to be concerned about from an SEO perspective? My site is obviously not about Javascript and I don't want to dilute my page's topic or authority by repeating words that are not relevant to the topic of my site.</p> <p>Thanks!</p></noscript>

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,

How to get Google to index another page
Hi, I will try to make my question clear, although it is a bit complex. For my site the most important keyword is "Insurance" or at least the danish variation of this. My problem is that Google are'nt indexing my frontpage on this, but are indexing a subpage - www.mydomain.dk/insurance instead of www.mydomain.dk. My link bulding will be to subpages and to my main domain, but i wont be able to get that many links to www.mydomain.dk/insurance. So im interested in making my frontpage the page that is my main page for the keyword insurance, but without just blowing the traffic im getting from the subpage at the moment. Is there any solutions to do this? Thanks in advance.
