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)

What happens to crawled URLs subsequently blocked by robots.txt?
We have a very large store with 278,146 individual product pages. Since these are all various sizes and packaging quantities of less than 200 product categories my feeling is that Google would be better off making sure our category pages are indexed. I would like to block all product pages via robots.txt until we are sure all category pages are indexed, then unblock them. Our product pages rarely change, no ratings or product reviews so there is little reason for a search engine to revisit a product page. The sales team is afraid blocking a previously indexed product page will result in in it being removed from the Google index and would prefer to submit the categories by hand, 10 per day via requested crawling. Which is the better practice?

Is it ok to repeat a (focus) keyword used on a previous page, on a new page?
I am cataloguing the pages on our website in terms of which focus keyword has been used with the page. I've noticed that some pages repeated the same keyword / term. I've heard that it's not really good practice, as it's like telling google conflicting information, as the pages with the same keywords will be competing against each other. Is this correct information? If so, is the alternative to use various long-winded keywords instead? If not, meaning it's ok to repeat the keyword on different pages, is there a maximum recommended number of times that we want to repeat the word? Still new-ish to SEO, so any help is much appreciated! V.

How can I avoid duplicate content for a new landing page which is the same as an old one?
Hello mozers! I have a question about duplicate content for you... One on my clients pages have been dropping in search volume for a while now, and I've discovered it's because the search term isn't as popular as it used to be. So... we need to create a new landing page using a more popular search term. The page which is losing traffic is based on the search query "Can I put a solid roof on my conservatory" this only gets 0-10 searches per month according to the keyword explorer tool. However, if we changed this to "replacing conservatory roof with solid roof" this gets up to 500 searches per month. Muuuuch better! The issue is, I don't want to close down and re-direct the old page because it's got a featured snippet and sits in position 1. So I'd like to create another page instead... however, as the two are effectively the same content, I would then land myself in a duplicate content issue. If I were to put a rel="canonical" tag in the original "can I put a solid roof...." page but say the master page is now the new one, would that get around the issue?

If Robots.txt have blocked an Image (Image URL) but the other page which can be indexed has this image, how is the image treated?
Hi MOZers, This probably is a dumb question but I have a case where the robots.tags has an image url blocked but this image is used on a page (lets call it Page A) which can be indexed. If the image on Page A has an Alt tags, then how is this information digested by crawlers? A) would Google totally ignore the image and the ALT tags information? OR B) Google would consider the ALT tags information? I am asking this because all the images on the website are blocked by robots.txt at the moment but I would really like website crawlers to crawl the alt tags information. Chances are that I will ask the webmaster to allow indexing of images too but I would like to understand what's happening currently. Looking forward to all your responses 🙂 Malika

"noindex, follow" or "robots.txt" for thin content pages
Does anyone have any testing evidence what is better to use for pages with thin content, yet important pages to keep on a website? I am referring to content shared across multiple websites (such as e-commerce, real estate etc). Imagine a website with 300 high quality pages indexed and 5,000 thin product type pages, which are pages that would not generate relevant search traffic. Question goes: Does the interlinking value achieved by "noindex, follow" outweigh the negative of Google having to crawl all those "noindex" pages? With robots.txt one has Google's crawling focus on just the important pages that are indexed and that may give ranking a boost. Any experiments with insight to this would be great. I do get the story about "make the pages unique", "get customer reviews and comments" etc....but the above question is the important question here.

Artist Bios on Multiple Pages: Duplicate Content or not?
I am currently working on an eComm site for a company that sells art prints. On each print's page, there is a bio about the artist followed by a couple of paragraphs about the print. My concern is that some artists have hundreds of prints on this site, and the bio is reprinted on every page,which makes sense from a usability standpoint, but I am concerned that it will trigger a duplicate content penalty from Google. Some people are trying to convince me that Google won't penalize for this content, since the intent is not to game the SERPs. However, I'm not confident that this isn't being penalized already, or that it won't be in the near future. Because it is just a section of text that is duplicated, but the rest of the text on each page is original, I can't use the rel=canonical tag. I've thought about putting each artist bio into a graphic, but that is a huge undertaking, and not the most elegant solution. Could I put the bio on a separate page with only the artist's info and then place that data on each print page using an <iframe>and then put a noindex,nofollow in the robots.txt file?</p> <p>Is there a better solution? Is this effort even necessary?</p> <p>Thoughts?</p></iframe>

Soft 404's from pages blocked by robots.txt -- cause for concern?
We're seeing soft 404 errors appear in our google webmaster tools section on pages that are blocked by robots.txt (our search result pages). Should we be concerned? Is there anything we can do about this?
