Duplicate Content Reports
-
Hi
Dupe content reports for a new client are sjhowing very high numbers (8000+) main of them seem to be for sign in, register, & login type pages, is this a scenario where best course of action to resolve is likely to be via the parameter handling tool in GWT ?
Cheers

You don't absolutely have to do both, but by doing the parameter handling you are sending another signal to Google of what you want them to do (keep in mind that both canonical and parameters are only considered suggestions by Google). It's pretty simple to setup the parameter handling, so if you are really concerned about the duplicate content issues, why not do both?
Also, technically, the canonical tag tells Google which URL they've crawled to give prominence to when they are duplicate content, whereas my understanding is that parameter handling (when Google follows your suggestions) actually prevents Google from even crawling URLs with those parameters. In other words, canonical tags tell Google what to do with URLs they've crawled and parameter handling tells Google what URLs not to even crawl.

Thanks Kurt
and what about the parameter handling tool ? if canonical tag method you mention will deal with this then is there any need to do anything with parameter handling tool ?
cheers

I would answer the same as Kurt for the install. You put the noindex tag in the header of the core page and so when all the other pages are generated with the parameters it will be added to those pages automatically. Once you get the pages out of the index, then I would nofollow links or use robots.txt to those pages to keep the bots out to start with.

Hi Dan,
I mean both. The canonical tag will help with duplicate content issues and the parameter handling will help with indexing.
Setting up the canonical tag shouldn't be an issue. If the same page content is being displayed and the only difference is that the URL has some parameters in it, then the canonical tag should naturally be included with the rest of the page's code. Since the canonical tag doesn't change, it should work perfectly.
For example, if you have a page, login.php, and that page always has a parameter, ?visitor=### (where ### is a random number), then you simply put the canonical tag in the head of the login.php page (). That canonical tag will always be in the login.php page no matter whether the URL is login.php?visitor=123 or login.php?visitor=56, etc. It will always tell the search engines that the original page login.php.

Thanks Clever PHD
So is there a way of setting a general rule to apply noindex to all of these duplicates or do you mean to the main actual sign in/login pages which will hence apply to all new, sessions specific, duplicate versions of the main sign-in/log-in pages etc when generated ?
Cheers

HI Kurt
Do you mean both or one or the other ?
Isn't setting up canonical tags on all the possible dynamically generated login, sign up and registration type pages impossible e can you set up some sort of rule that applies to those unpredictable (since we dont know what they are until they are generated by a user session etc) pages ?
Cheers

You can also noindex those pages to simply take them out of the index and then later nofollow links to them.

You can use the parameter handling and setup canonical tags on the pages.

#1 rankings on both HTTP and HTTPS vs duplicate content
We're planning a full migrate to HTTPS for our website which is accessible today by both **www.**website.com, **http://**www.website.com as well as **https://**www.website.com. After the migrate the website will only be accessible by https requests and every other request (Ex. www or http) will be redirected to the same page but in HTTPS by 301 redirects. We've taken a lot of precautions like fixing all the internal links to HTTPS instead of HTTP etc. My questions is: What happened to your rankings for HTTP after making a full migrate to HTTPS?

Duplicate Content within Site
I'm very new here... been reading a lot about Panda and duplicate content. I have a main website and a mobile site (same domain - m.domain.com). I've copied the same text over to those other web pages. Is that okay? Or is that considered duplicate content?

Duplicate content on user queries
Our website supports a unique business industry where our users will come to us to look for something very specific (a very specific product name) to find out where they can get it. The problem that we're facing is that the products are constantly changing due to the industry. So, for example, one month, one product might be found on our website, and the next, it might be removed completely... and then might come back again a couple months later. All things that are completely out of our control - and we have no way of receiving any sort of warning when these things might happen. Because of this, we're seeing a lot of duplicate content issues arise... For Example... Product A is not active today... so www.mysite.com/search/productA will return no results... Product B is also not active today... so www.mysite.com/search/productB will also return no results. As per Moz Analytics, these are showing up as duplicate content because both pages indicate "No results were found for {your searched term}." Unfortunately, it's a bit difficult to return a 204 in these situations (which I don't know if a 204 would help anyway) or a 404, because, for a faster user experience, we simultaneously render different sections of the page... so in the very beginning of the page load - we start rendering the faster content (template type of content) that says "returning 200 code, we got the query successfully & we're loading the page".. the unique content results finish loading last since they take the longest. I'm still very new to the SEO world, so would greatly appreciate any ideas or suggestions that might help with this... I'm stuck. 😛 Thanks in advance!

Duplicate Content in Dot Net Nuke
Our site is built on Dot Net Nuke. SEOmoz shows a very large amount of duplicate content because at the beginning each page got an extension in the following format: www.domain.com/tabid/110/Default.aspx The site additionally exists without the tabid... part. Our web developer says an easy fix with a canonical tag or 301 redirect is not possible. Does anyone have DNN experience and can point us in the right direction? Thanks, Ricarda

Duplicate Content on Navigation Structures
Hello SEOMoz Team, My organization is making a push to have a seamless navigation across all of its domains. Each of the domains publishes distinctly different content about various subjects. We want each of the domains to have its own separate identity as viewed by Google. It has been suggested internally that we keep the exact same navigation structure (40-50 links in the header) across the header of each of our 15 domains to ensure "unity" among all of the sites. Will this create a problem with duplicate content in the form of the menu structure, and will this cause Google to not consider the domains as being separate from each other? Thanks, Richard Robbins

Duplicate Page Content and Titles
A few weeks ago my error count went up for Duplicate Page Content and Titles. 4 errors in all. A week later the errors were gone... But now they are back. I made changes to the Webconfig over a month ago but nothing since. SEOmoz is telling me the duplicate content is this http://www.antiquebanknotes.com/ and http://www.antiquebanknotes.com Thanks for any advise! This is the relevant web.config. <rewrite><rules><rule name="CanonicalHostNameRule1"><match url="(.*)"><conditions><add input="{HTTP_HOST}" pattern="^www.antiquebanknotes.com$" negate="true"></add></conditions>

Mapping Internal Links (Which are causing duplicate content)
I'm working on a site that is throwing off a -lot- of duplicate content for its size. A lot of it appears to be coming from bad links within the site itself, which were caused when it was ported over from static HTML to Expression Engine (by someone else). I'm finding EE an incredibly frustrating platform to work with, as it appears to be directing 404's on sub-pages to the page directly above that subpage, without actually providing a 404 response. It's very weird. Does anyone have any recommendations on software to clearly map out a site's internal link structure so that I can find what bad links are pointing to the wrong pages?

Avoiding duplicate content/same pages
hi I have been checking through all the Q and A but i i'm still not sure how you get http://www.domain.co.uk/index.html to be just http://www.domain.co.uk/? Do you add canonical to the index page to point to the page you prefer and then add a 301 redirect? thanks
