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://a-moz.groupbuyseo.org/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

How to check if an individual page is indexed by Google?
So my understanding is that you can use site: [page url without http] to check if a page is indexed by Google, is this 100% reliable though? Just recently Ive worked on a few pages that have not shown up when Ive checked them using site: but they do show up when using info: and also show their cached versions, also the rest of the site and pages above it (the url I was checking was quite deep) are indexed just fine. What does this mean? thank you p.s I do not have WMT or GA access for these sites

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>

Should I put meta descriptions on pages that are not indexed?
I have multiple pages that I do not want to be indexed (and they are currently not indexed, so that's great). They don't have meta descriptions on them and I'm wondering if it's worth my time to go in and insert them, since they should hypothetically never be shown. Does anyone have any experience with this? Thanks! The reason this is a question is because one member of our team was linking to this page through Facebook to send people to it and noticed random text on the page being pulled in as the description.

301 Redirect with index.asp
I am very new to all of this so forgive the newbie questions I will get better. Ok so after starting a campaign I see that I have many issues including where some pages are being deemed as duplicate content. 1. The report says the http://lucid8.com has duplicate content on 2 other pages 2. When I look at them it shows that http://lucid8.com/index.asp and http://www.lucid8.com are duplicates. 3. Really these are the exactly the same page because the default page that is opened for www.lucid8.com http://www.lucid8.com etc always opens the index.asp page. 4. Now I read that I should do permanent redirects and how to do this via IIS and I tried to do a redirect from index.asp to www.lucid8.com but that does not work because www.lucid8.com is pointing to index.asp and so we end up in a circle. So the question is how do I get rid of these duplicate page references without causing problems. Thanks

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.
