Duplicate content q - Can search engines tell where the original text was copied from?
-
I was under the impression that when a search engine comes across duplicate content it won't be able to determine which one is the original. Is this not the case?
-
Not sure canonical tags work that way! You use the canonical tag to provide the search engines with the "official" URL of your content. This is especially useful when you're using a CMS that delivers your content on a number of alternate urls. It won't help search engines determine the "owner" of the content.
Matt Cutts has said that Google is getting better at identifying the original owner of the site, but it's not perfect. Google don't have a magic way of seeing everything that goes on, they have to crawl which takes time.
I don't know if it would help if you manually submit your page to google using the Google Webmaster tools / fetch as googlebot option as soon as you purplish your page. Might help get your page into the index first. Not exactly a scalable approach if you're publishing a lot of material though.
One of the best ways of protecting yourself is to embed relevant (absolute) links into the body of your content pointing to related articles on your own site. One website I'm working on gets a surprising number of referrals that way! Oh,also think about adding links to your new content from some of your older content, if it's relevant and makes sense to do so.
Authorship markup might also help.

What if both sites added canonical tags on their content?
-
That all depends if the site that you have taken the content from has placed canonical tags on there content which says that there site was the original owner of the content. This means that you will get seen as having duplicate content and they wont.

Home page duplicate content...
Hello all! I've just downloaded my first Moz crawl CSV and I noticed that the home page appears twice - one with an appending forward slash at the end: http://www.example.com

Tags, Categories, & Duplicate Content
Looking for some advice on a duplicate content issue that we're having that definitely isn't unique to us. See, we are allowing all our tag and category pages, as well as our blog pagination be indexed and followed, but Moz is detecting that all as duplicate content, which is obvious since it is the same content that is on our blog posts. We've decided in the past to keep these pages the way they are as it hasn't seemed to hurt us specifically and we hoped it would help our overall ranking. We haven't seen positive or negative signals either way, just the warnings from Moz. We are wondering if we should noindex these pages and if that could cause a positive change, but we're worried it might cause a big negative change as well. Have you confronted this issue? What did you decide and what were the results? Thanks in advance!

Somehow it seems maybe because the pinned the images on pinterest but the CDN got indexed and there now seems to be about 50% of the site duplicated (about 2500 pages eg: http://d2rf6flfy1l.cloudfront.net..) Is this a problem with duplicate content? How come Moz doesnt show it up as crawl errors?

Duplicate Title and Content. How to fix?
So this is the biggest error I have. But I don't know how to fix it. I get that I have to make it so that the duplicats redirect to the source, but I don't know how to do that. For example, this is out of our crawl diagnostic: | On The Block - Page 3 http://www.maddenstudents.com/forumdisplay.php?57-On-The-Block/page3 1 1 0 On The Block - Page 3 http://www.maddenstudents.com/forumdisplay.php?57-On-The-Block/page3&s=8d631e0ac09b7a462164132b60433f98 | 1 | 1 | 0 | That's just an example. But I have over 1000+ like that. How would I go about fixing that? Getting rid of the "&s=8d631e0ac09b7a462164132b60433f98"? I have godaddy as my domain and web hoster. Could they be able to fix it?

404's and duplicate content.
I have real estate based websites that add new pages when new listings are added to the market and then deletes pages when the property is sold. My concern is that there are a significant amount of 404's created and the listing pages that are added are going to be the same as others in my market who use the same IDX provider. I can go with a different IDX provider that uses IFrame which doesn't create new pages but I used a IFrame before and my time on site was 3min w/ 2.5 pgs per visit and now it's 7.5 pg/visit with 6+min on the site. The new pages create new content daily so is fresh content and better on site metrics (with the 404's) better or less 404's, no dup content and shorter onsite metrics better? Any thoughts on this issue? Any advice would be appreciated

Block Quotes and Citations for duplicate content
I've been reading about the proper use for block quotes and citations lately, and wanted to see if I was interpreting it the right way. This is what I read: http://www.pitstopmedia.com/sem/blockquote-cite-q-tags-seo So basically my question is, if I wanted to reference Amazon or another stores product reviews, could I use the block quote and citation tags around their content so it doesn't look like duplicate content? I think it would be great for my visitors, but also to the source as I am giving them credit. It would also be a good source to link to on my products pages, as I am not competing with the manufacturer for sales. I could also do this for product information right from the manufacturer. I want to do this for a contact lens site. I'd like to use Acuvue's reviews from their website, as well as some of their product descriptions. Of course I have my own user reviews and content for each product on my website, but I think some official copy could do well. Would this be the best method? Is this how Rottentomatoes.com does it? On every movie page they have 2-3 sentences from 50 or so reviews, and not much unique content of their own. Cheers, Vinnie
