Could you use a robots.txt file to disalow a duplicate content page from being crawled?
-
A website has duplicate content pages to make it easier for users to find the information from a couple spots in the site navigation. Site owner would like to keep it this way without hurting SEO.
I've thought of using the robots.txt file to disallow search engines from crawling one of the pages. Would you think this is a workable/acceptable solution?
-
Yeah, sorry for the confusion. I put the tag on all the pages (Original and Duplicate). I sent you a PM with another good article on Rel canonical tag
-
Peter, Thanks for the clarification.
-
Generally agree, although I'd just add that Robots.txt also isn't so great at removing content that's already been indexed (it's better at prevention). So, I find that it's not just not ideal - it sometimes doesn't even work in these cases.
Rel-canonical is generally a good bet, and it should go on the duplicate (you can actually put it on both, although it's not necessary).

Next time I'll read the reference links better
Thank you!

per google webmaster tools:
If Google knows that these pages have the same content, we may index only one version for our search results. Our algorithms select the page we think best answers the user's query. Now, however, users can specify a canonical page to search engines by adding a element with the attribute
rel="canonical"to the section of the non-canonical version of the page. Adding this link and attribute lets site owners identify sets of identical content and suggest to Google: "Of all these pages with identical content, this page is the most useful. Please prioritize it in search results." -
Thanks Kyle. Anthony had a similar view on using the rel canonical tag. I'm just curious about adding it to both the original page or duplicate page? Or both?
Thanks,
Greg

Anthony, Thanks for your response. See Kyle, he also felt using the rel canonical tag was the best thing to do. However he seemed to think you'd put it on the original page - the one you want to rank for. And you're suggesting putting on the duplicate page. Should it be added to both while specifying which page is the 'original'?
Thanks!
Greg

I'm not sure I understand why the site owner seems to think that the duplicate content is necessary?
If I was in your situation I would be trying to convince the client to remove the duplicate content from their site, rather than trying to find a way around it.
If the information is difficult to find then this may be due to a problem with the site architecture. If the site does not flow well enough for visitors to find the information they need, then perhaps a site redesign is necessary.
-
Well, the answer would be yes and no. A robots.txt file would stop the bots from indexing the page, but links from other pages in site to that non indexed page could therefor make it crawlable and then indexed. AS posted in google webmaster tools here:
"You need a robots.txt file only if your site includes content that you don't want search engines to index. If you want search engines to index everything in your site, you don't need a robots.txt file (not even an empty one).
While Google won't crawl or index the content of pages blocked by robots.txt, we may still index the URLs if we find them on other pages on the web. As a result, the URL of the page and, potentially, other publicly available information such as anchor text in links to the site, or the title from the Open Directory Project (www.dmoz.org), can appear in Google search results."
I think the best way to avoid any conflict is applying the rel="canonical" tag to each duplicate page that you don't want indexed.
You can find more info on rel canonical here
Hope this helps out some.

The best way would be to use the Rel canonical tag
On the page you would like to rank for put the Rel canonical tag in
This lets google know that this is the original page.Check out this link posted by Rand about the Rel canonical tag [http://www.seomoz.org/blog/canonical-url-tag-the-most-important-advancement-in-seo-practices-since-sitemaps](http://www.seomoz.org/blog/canonical-url-tag-the-most-important-advancement-in-seo-practices-since-sitemaps)

Can I use duplicate content in different US cities without hurting SEO?
So, I have major concerns with this plan. My company has hundreds of facilities located all over the country. Each facility has it's own website. We have a third party company working to build a content strategy for us. What they came up with is to create a bank of content specific to each service line. If/when any facility offers that service, they then upload the content for that service line to that facility website. So in theory, you might have 10-12 websites all in different cities, with the same content for a service. They claim "Google is smart, it knows its content all from the same company, and because it's in different local markets, it will still rank." My contention is that duplicate content is duplicate content, and unless it is "localize" it, Google is going to prioritize one page of it and the rest will get very little exposure in the rankings no matter where you are. I could be wrong, but I want to be sure we aren't shooting ourselves in the foot with this strategy, because it is a major major undertaking and too important to go off in the wrong direction. SEO Experts, your help is genuinely appreciated!

Directory with Duplicate content? what to do?
Moz keeps finding loads of pages with duplicate content on my website. The problem is its a directory page to different locations. E.g if we were a clothes shop we would be listing our locations: www.sitename.com/locations/london www.sitename.com/locations/rome www.sitename.com/locations/germany The content on these pages is all the same, except for an embedded google map that shows the location of the place. The problem is that google thinks all these pages are duplicated content. Should i set a canonical link on every single page saying that www.sitename.com/locations/london is the main page? I don't know if i can use canonical links because the page content isn't identical because of the embedded map. Help would be appreciated. Thanks.

Large robots.txt file
We're looking at potentially creating a robots.txt with 1450 lines in it. This will remove 100k+ pages from the crawl that are all old pages (I know, the ideal would be to delete/noindex but not viable unfortunately) Now the issue i'm thinking is that a large robots.txt will either stop the robots.txt from being followed or will slow our crawl rate down. Does anybody have any experience with a robots.txt of that size?

Should I use meta noindex and robots.txt disallow?
Hi, we have an alternate "list view" version of every one of our search results pages The list view has its own URL, indicated by a URL parameter I'm concerned about wasting our crawl budget on all these list view pages, which effectively doubles the amount of pages that need crawling When they were first launched, I had the noindex meta tag be placed on all list view pages, but I'm concerned that they are still being crawled Should I therefore go ahead and also apply a robots.txt disallow on that parameter to ensure that no crawling occurs? Or, will Googlebot/Bingbot also stop crawling that page over time? I assume that noindex still means "crawl"... Thanks 🙂

International SEO - cannibalisation and duplicate content
Hello all, I look after (in house) 3 domains for one niche travel business across three TLDs: .com .com.au and co.uk and a fourth domain on a co.nz TLD which was recently removed from Googles index. Symptoms: For the past 12 months we have been experiencing canibalisation in the SERPs (namely .com.au being rendered in .com) and Panda related ranking devaluations between our .com site and com.au site. Around 12 months ago the .com TLD was hit hard (80% drop in target KWs) by Panda (probably) and we began to action the below changes. Around 6 weeks ago our .com TLD saw big overnight increases in rankings (to date a 70% averaged increase). However, almost to the same percentage we saw in the .com TLD we suffered significant drops in our .com.au rankings. Basically Google seemed to switch its attention from .com TLD to the .com.au TLD. Note: Each TLD is over 6 years old, we've never proactively gone after links (Penguin) and have always aimed for quality in an often spammy industry. **Have done: ** Adding HREF LANG markup to all pages on all domain Each TLD uses local vernacular e.g for the .com site is American Each TLD has pricing in the regional currency Each TLD has details of the respective local offices, the copy references the lacation, we have significant press coverage in each country like The Guardian for our .co.uk site and Sydney Morning Herlad for our Australia site Targeting each site to its respective market in WMT Each TLDs core-pages (within 3 clicks of the primary nav) are 100% unique We're continuing to re-write and publish unique content to each TLD on a weekly basis As the .co.nz site drove such little traffic re-wrting we added no-idex and the TLD has almost compelte dissapread (16% of pages remain) from the SERPs. XML sitemaps Google + profile for each TLD **Have not done: ** Hosted each TLD on a local server Around 600 pages per TLD are duplicated across all TLDs (roughly 50% of all content). These are way down the IA but still duplicated. Images/video sources from local servers Added address and contact details using SCHEMA markup Any help, advice or just validation on this subject would be appreciated! Kian

Using 2 wildcards in the robots.txt file
I have a URL string which I don't want to be indexed. it includes the characters _Q1 ni the middle of the string. So in the robots.txt can I use 2 wildcards in the string to take out all of the URLs with that in it? So something like /_Q1. Will that pickup and block every URL with those characters in the string? Also, this is not directly of the root, but in a secondary directory, so .com/.../_Q1. So do I have to format the robots.txt as //_Q1* as it will be in the second folder or just using /_Q1 will pickup everything no matter what folder it is on? Thanks.

Block an entire subdomain with robots.txt?
Is it possible to block an entire subdomain with robots.txt? I write for a blog that has their root domain as well as a subdomain pointing to the exact same IP. Getting rid of the option is not an option so I'd like to explore other options to avoid duplicate content. Any ideas?
