Moz Q&A is closed.
After more than 13 years, and tens of thousands of questions, Moz Q&A closed on 12th December 2024. Whilst we’re not completely removing the content - many posts will still be possible to view - we have locked both new posts and new replies. More details here.
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)

Duplicate content in Shopify - subsequent pages in collections
Hello everyone! I hope an expert in this community can help me verify the canonical codes I'll add to our store is correct. Currently, in our Shopify store, the subsequent pages in the collections are not indexed by Google, however the canonical URL on these pages aren't pointing to the main collection page (page 1), e.g. The canonical URL of page 2, page 3 etc are used as canonical URLs instead of the first page of the collections. I have the canonical codes attached below, it would be much appreciated if an expert can urgently verify these codes are good to use and will solve the above issues? Thanks so much for your kind help in advance!! -----------------CODES BELOW--------------- <title><br /> {{ page_title }}{% if current_tags %} – tagged "{{ current_tags | join: ', ' }}"{% endif %}{% if current_page != 1 %} – Page {{ current_page }}{% endif %}{% unless page_title contains shop.name %} – {{ shop.name }}{% endunless %}<br /></title>

Blocking Pages Via Robots, Can Images On Those Pages Be Included In Image Search
Hi! I have pages within my forum where visitors can upload photos. When they upload photos they provide a simple statement about the photo but no real information about the image,definitely not enough for the page to be deemed worthy of being indexed. The industry however is one that really leans on images and having the images in Google Image search is important to us. The url structure is like such: domain.com/community/photos/~username~/picture111111.aspx I wish to block the whole folder from Googlebot to prevent these low quality pages from being added to Google's main SERP results. This would be something like this: User-agent: googlebot Disallow: /community/photos/ Can I disallow Googlebot specifically rather than just using User-agent: * which would then allow googlebot-image to pick up the photos? I plan on configuring a way to add meaningful alt attributes and image names to assist in visibility, but the actual act of blocking the pages and getting the images picked up... Is this possible? Thanks! Leona

Duplicate Content | eBay
My client is generating templates for his eBay template based on content he has on his eCommerce platform. I'm 100% sure this will cause duplicate content issues. My question is this.. and I'm not sure where eBay policy stands with this but adding the canonical tag to the template.. will this work if it's coming from a different page i.e. eBay? Update: I'm not finding any information regarding this on the eBay policy's: http://ocs.ebay.com/ws/eBayISAPI.dll?CustomerSupport&action=0&searchstring=canonical So it does look like I can have rel="canonical" tag in custom eBay templates but I'm concern this can be considered: "cheating" since rel="canonical is actually a 301 but as this says: http://googlewebmastercentral.blogspot.com/2009/12/handling-legitimate-cross-domain.html it's legitimately duplicate content. The question is now: should I add it or not? UPDATE seems eBay templates are embedded in a iframe but the snap shot on google actually shows the template. This makes me wonder how they are handling iframes now. looking at http://www.webmaster-toolkit.com/search-engine-simulator.shtml does shows the content inside the iframe. Interesting. Anyone else have feedback?
