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://azwa.1clkaccess.in/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.

Should search pages be indexed?
Hey guys, I've always believed that search pages should be no-indexed but now I'm wondering if there is an argument to index them? Appreciate any thoughts!

If we were to deploy schema and noindex tags to our website via Google tag manager, would these tags be viewed and respected by other search engines?

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

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

Google indexing despite robots.txt block
Hi This subdomain has about 4'000 URLs indexed in Google, although it's blocked via robots.txt: https://www.google.com/search?safe=off&q=site%3Awww1.swisscom.ch&oq=site%3Awww1.swisscom.ch This has been the case for almost a year now, and it does not look like Google tends to respect the blocking in http://www1.swisscom.ch/robots.txt Any clues why this is or what I could do to resolve it? Thanks!

How to Stop Google from Indexing Old Pages
We moved from a .php site to a java site on April 10th. It's almost 2 months later and Google continues to crawl old pages that no longer exist (225,430 Not Found Errors to be exact). These pages no longer exist on the site and there are no internal or external links pointing to these pages. Google has crawled the site since the go live, but continues to try and crawl these pages. What are my next steps?

Having www. and non www. links indexed
Hey guys, As the title states, the two versions of the website are indexed in Google. How should I proceed? Please also note that the links on the website are without the www. How should I proceed knowing that the client prefers to have the www. version indexed. Here are the steps that I have in mind right now: I set the preferred domain on GWMT as the one with www. I 301 redirect any non www. URL to the www. version. What are your thoughts? Should I 301 redirect the URL's? or is setting the preference on GWMT enough? 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.
